Session Peering Provisioning (SPP) Protocol over SOAP
Abstract
The Session Peering Provisioning Framework (SPPF) specifies the data
model and the overall structure to provision Session Establishment
Data (SED) into Session Data Registries and SIP Service Provider data
stores. To utilize this framework, one needs a substrate protocol.
Given that the Simple Object Access Protocol (SOAP) is currently
widely used for messaging between elements of such provisioning
systems, this document specifies the usage of SOAP (via HTTPS) as the
substrate protocol for SPPF. The benefits include leveraging
prevalent expertise and a higher probability that existing
provisioning systems will be able to easily migrate to using an SPPF-
based protocol.

1. Introduction
SPPF, defined in [RFC7877], is best supported by a transport and
messaging infrastructure that is connection oriented, is request-
response oriented, is easily secured, supports propagation through
firewalls in a standard fashion, and is easily integrated into back-
office systems. This is due to the fact that the client side of SPPF
is likely to be integrated with organizations' operational support
systems that facilitate transactional provisioning of user addresses
and their associated SED. The server side of SPPF is likely to
reside in a separate organization's network, resulting in the SPPF
provisioning transactions traversing the Internet as they are
propagated from the SPPF client to the SPPF server. Given the
current state of industry practice and technologies, SOAP and HTTP(S)
are well suited for this type of environment. This document
describes the specification for transporting SPPF XML structures,
using SOAP and HTTP(S) as substrates.
The specification in this document for transporting SPPF XML
structures over SOAP and HTTP(S) is primarily comprised of five
subjects: (1) a description of any applicable SOAP features, (2) any
Cartwright, et al. Standards Track [Page 3]
RFC 7878 SPP Protocol over SOAP August 2016
applicable HTTP features, (3) security considerations, (4) (perhaps
most importantly) the Web Services Description Language (WSDL)
definition for the SPP Protocol over SOAP, and (5) XML Schema
Definition (XSD) types that are "substrate" specific.
2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
3. SOAP Features and Protocol Layering
The list of SOAP features that are explicitly used and required for
SPPP over SOAP are limited. Most SOAP features are not necessary for
SPPF. SPPP over SOAP primarily uses SOAP simply as a standard
message-envelope technology. The SOAP message envelope is comprised
of the SOAP header and body. As described in the SOAP specification
[SOAPREF], the SOAP header can contain optional, application-
specific, information about the message. The SOAP body contains the
SPPF message itself, whose structure is defined by the combination of
one of the WSDL operations defined in this document and the SPPF XML
data structures defined in this document and the SPPF document. SPPF
does not rely on any data elements in the SOAP header. All relevant
data elements are defined in the SPPF XML Schema described in
[RFC7877] and the SPPF WSDL types specification described in
Section 9 of this document.
WSDL is a widely standardized and adopted technology for defining the
top-level structures of the messages that are transported within the
body of a SOAP message. The WSDL definition for the SPPF SOAP
messages is defined later in this document, which imports by
reference the XML data types contained in the SPPF schema. The IANA
registry where the SPPF schema resides is described in "The IETF XML
Registry" [RFC3688].
There are multiple structural styles that WSDL allows. The best
practice for this type of application is what is sometimes referred
to as the "document/literal wrapped style". This style is generally
regarded as an optimal approach that enhances maintainability,
comprehension, portability, and, to a certain extent, performance.
It is characterized by setting the soapAction binding style as
"document", the soapAction encoding style as "literal", and then
defining the SOAP messages to simply contain a single data element
that "wraps" a data structure containing all the required input or
output data elements. The figure below illustrates this high-level
technical structure as conceptual layers 3 through 6.

RFC 7878 SPP Protocol over SOAP August 2016
The operations supported by SPPP over SOAP are normatively defined
later in this document. Each SOAP operation defines a request/input
message and a response/output message. Each such request and
response message then contains a single object that wraps the SPPF
XML data types that comprise the inputs and the outputs,
respectively, of the SOAP operation.
SOAP faults are not used by the SPPP over SOAP. All success and
error responses are specified in Section 7.3 of this document.
However, if a SOAP fault were to occur, perhaps due to failures in
the SOAP message handling layer of a SOAP library, the client
application should capture and handle the fault. Specifics on how to
handle such SOAP faults, if they should occur, will be specific to
the chosen SOAP implementation.
Implementations MUST use SOAP 1.2 [SOAPREF] or higher and MUST
support SOAP 1.2. Implementations SHOULD use WSDL 1.1 [WSDLREF] and
MUST NOT use earlier versions. Use of WSDL versions greater than 1.1
may introduce interoperability problems with implementations that use
1.1.
SPPF is a request/reply framework that allows a client application to
submit provisioning data and query requests to a server. The SPPF
data structures are designed to be protocol agnostic. Concerns
regarding encryption, non-repudiation, and authentication are beyond
the scope of this document. For more details, please refer to
Section 4 ("Transport Substrate Protocol Requirements") of [RFC7877].
As illustrated in the previous diagram, SPPF can be viewed as a set
of layers that collectively define the structure of an SPPF request
and response. Layers 1 and 2 represent the transport, envelope, and
authentication technologies. This document defines layers 3, 4, 5,
and 6 for SPPP over SOAP.
1. Layer 1: The transport protocol layer represents the
communication mechanism between the client and server. SPPF can
be layered over any substrate protocol that provides a set of
basic requirements defined in Section 4 of [RFC7877].
2. Layer 2: The message-envelope layer is optional but can provide
features that are above the transport technology layer but below
the application messaging layer. Technologies such as HTTP and
SOAP are examples of message-envelope technologies.
3. Layers 3, 4, 5, and 6: The operation and message layers provide
an envelope-independent and substrate-independent wrapper for the
SPPF data model objects that are being acted on (created,
modified, and queried).
Cartwright, et al. Standards Track [Page 6]
RFC 7878 SPP Protocol over SOAP August 2016
4. HTTP(S) Features and SPPP over SOAP
While SOAP is not tied to HTTP(S), for reasons described in the
Introduction, HTTP(S) is a good choice as the substrate protocol for
the SPP Protocol SOAP messages. HTTP 1.1 includes the "persistent
connection" feature, which allows multiple HTTP request/response
pairs to be transported across a single HTTP connection. This is an
important performance optimization feature, particularly when the
connection is an HTTPS connection where the relatively time-consuming
TLS handshake has occurred.
Implementations compliant with this document MUST use HTTP 1.1
[RFC7230] or higher. Also, implementations SHOULD use persistent
connections.
5. Authentication, Integrity, and Confidentiality
To accomplish authentication, conforming SPPP over SOAP clients and
servers MUST use HTTP Digest Authentication as defined in [RFC7235].
To achieve integrity and privacy, conforming SPPP over SOAP clients
and servers MUST support TLS as defined in [RFC5246] as the secure
transport mechanism. Use of TLS MUST follow the recommendations
contained in [RFC7525]
6. Language Identification
Section 9 of [RFC7877] requires protocols to provide a mechanism to
transmit language tags together with human-readable messages. When
conforming SPPP SOAP servers use such tagging, the XML "lang"
attribute ([W3C.REC-xml-20081126], Section 2.12) MUST be used.
Clients MAY use the HTTP "Accept-Language" header field (see
Section 5.3.5 of [RFC7231]) in order to indicate their language
preference.
7. SPPP SOAP Data Structures
SPPP over SOAP uses a set of XML-based data structures for all the
supported operations and any parameters to which those operations are
applied. As also mentioned earlier in this document, these XML
structures are envelope independent and substrate independent. Refer
to "Protocol Operations" (Section 8) of this document for a
description of all the operations that MUST be supported.
The following sections describe the definitions of all the XML data
structures.
Cartwright, et al. Standards Track [Page 7]
RFC 7878 SPP Protocol over SOAP August 2016
7.1. Concrete Object Key Types
Certain operations in SPPF require an object key that uniquely
identifies the object(s) on which a given operation needs to be
performed. SPPF defines the XML structure of any such object key in
an abstract manner and delegates the concrete representation to any
conforming substrate protocol. The following subsections define the
various types of concrete object key types used in various operations
in SPPP over SOAP.
7.1.1. Generic Object Key
Most objects in SPPP over SOAP are uniquely identified by the
attributes in the generic object key (Refer to "Generic Object Key
Type", Section 5.2.1 of [RFC7877], for details). The concrete XML
representation of ObjKeyType is as below:
<complexType name="ObjKeyType">
<complexContent>
<extension base="sppfb:ObjKeyType">
<sequence>
<element name="rant" type="sppfb:OrgIdType"/>
<element name="name" type="sppfb:ObjNameType"/>
<element name="type" type="sppfs:ObjKeyTypeEnum"/>
</sequence>
</extension>
</complexContent>
</complexType>
The ObjKeyType has the data elements as described below:
o rant: The identifier of the Registrant organization that owns the
object.
o name: The character string that contains the name of the object.
o type: The enumeration value that represents the type of SPPF
object. For example, both a Destination Group and a SED Group can
have the same name "TestObj" and be associated with the same
Registrant ID. Hence, to uniquely identify the object that
represents a Destination Group with the name "TestObj", the type
"DestGrp" must be specified when using this concrete ObjKeyType
structure to identify the Destination Group "TestObj".
Cartwright, et al. Standards Track [Page 8]
RFC 7878 SPP Protocol over SOAP August 2016
The object types in SPPP over SOAP MUST adhere to the above
definition of generic object key and are defined as an enumeration in
the XML data structure as follows:
<simpleType name="ObjKeyTypeEnum">
<restriction base="token">
<enumeration value="SedGrp"/>
<enumeration value="DestGrp"/>
<enumeration value="SedRec"/>
<enumeration value="EgrRte"/>
</restriction>
</simpleType>
7.1.2. Public Identifier Object Key
Public Identifier type objects can further be of various sub-types
like a Telephone Number (TN), Routing Number (RN), TN Prefix, URI, or
TN Range and cannot be cleanly identified with the attributes in the
generic ObjKeyType. The definition of PubIdKeyType is as below:
<complexType name="PubIdKeyType">
<complexContent>
<extension base="sppfb:PubIdKeyType">
<sequence>
<element name="rant" type="sppfb:OrgIdType"/>
<choice>
<element name="number"
type="sppfb:NumberType"/>
<element name="range"
type="sppfb:NumberRangeType"/>
<element name="uri"
type="anyURI"/>
</choice>
</sequence>
</extension>
</complexContent>
</complexType>
The PubIdKeyType has data elements, as described below:
o rant: The identifier of the Registrant organization that owns the
object.
o number: An element of type NumberType (refer to Section 12 of
[RFC7877]) that contains the value and type of a number.
o range: An element of type NumberRangeType (refer to Section 12 of
[RFC7877]) that contains a range of numbers.
Cartwright, et al. Standards Track [Page 9]
RFC 7878 SPP Protocol over SOAP August 2016
o uri: A value that represents a Public Identifier.
Any instance of PubIdKeyType MUST contain exactly one element from
the following set of elements: "number", "range", "uri".
7.1.3. SED Group Offer Key
In addition to the attributes in the generic ObjKeyType, a SED Group
Offer object is uniquely identified by the organization ID of the
organization to whom a SED Group has been offered. The definition of
SedGrpOfferKeyType is as below:
<complexType name="SedGrpOfferKeyType">
<complexContent>
<extension base="sppfb:SedGrpOfferKeyType">
<sequence>
<element name="sedGrpKey" type="sppfs:ObjKeyType"/>
<element name="offeredTo" type="sppfb:OrgIdType"/>
</sequence>
</extension>
</complexContent>
</complexType>
The SedGrpOfferKeyType has the data elements as described below:
o sedGrpKey: Identifies the SED Group that was offered.
o offeredTo: The organization ID of the organization that was
offered the SED Group object identified by the sedGrpKey.
7.2. Operation Request and Response Structures
An SPPF client interacts with an SPPF server by sending one or more
requests to the server and by receiving corresponding responses from
the server. The basic set of operations that an SPPF client can
submit to an SPPF server and the semantics of those operations are
defined in "Framework Operations", Section 7 of [RFC7877]. The
following subsections describe the XML data structures that are used
for each of those types of operations for an SPPP over SOAP
implementation.
7.2.1. Add Operation Structure
In order to add (or modify) an object in the Registry, an authorized
entity can send the spppAddRequest to the Registry.
Cartwright, et al. Standards Track [Page 10]
RFC 7878 SPP Protocol over SOAP August 2016
An SPPP over SOAP Add request is wrapped within the <spppAddRequest>
element while an SPPP over SOAP Add response is wrapped within an
<spppAddResponse> element. The following sub-sections describe the
<spppAddRequest> and <spppAddResponse> elements. Refer to Section 10
for an example of an Add operation on each type of SPPF object.
7.2.1.1. Add Request
An SPPP over SOAP Add request definition is contained within the
generic <spppAddRequest> element.
<element name="spppAddRequest">
<complexType>
<sequence>
<element name="clientTransId"
type="sppfb:TransIdType" minOccurs="0"/>
<element name="minorVer"
type="sppfb:MinorVerType" minOccurs="0"/>
<element name="obj" type="sppfb:BasicObjType"
maxOccurs="unbounded"/>
</sequence>
</complexType>
</element>
The data elements within the <spppAddRequest> element are described
as follows:
o clientTransId: Zero or one client-generated transaction ID that,
within the context of the SPPF client, identifies this request.
This value can be used at the discretion of the SPPF client to
track, log, or correlate requests and their responses. The SPPF
server MUST echo back this value to the client in the
corresponding response to the incoming request. The SPPF server
will not check this value for uniqueness.
o minorVer: Zero or one minor version identifier, as defined in
Section 7.4.
o obj: One or more elements of abstract type BasicObjType (defined
in [RFC7877]). Each element contains all the attributes of an
SPPF object that the client is requesting the SPPF server to add.
Refer to Section 3.1 of [RFC7877] for the XML structure of all
concrete types, for various SPPF objects, that extend from
abstract BasicObjType and hence are eligible to be passed into
this element. The elements are processed by the SPPF server in
the order in which they are included in the request. With respect
to the handling of error conditions, conforming SPPP SOAP servers
MUST stop processing BasicObjType elements in the request at the
Cartwright, et al. Standards Track [Page 11]
RFC 7878 SPP Protocol over SOAP August 2016
first error and roll back any BasicObjType elements that had
already been processed for that add request ("stop and roll
back").
7.2.1.2. Add Response
An SPPP over SOAP add response object is contained within the generic
<spppAddResponse> element. This response structure is used for all
types of SPPF objects that are provisioned by the SPPF client.
<element name="spppAddResponse">
<complexType>
<sequence>
<element name="clientTransId" type="sppfb:TransIdType"
minOccurs="0"/>
<element name="serverTransId" type="sppfb:TransIdType"/>
<element name="overallResult" type="sppfs:ResultCodeType"/>
<element name="detailResult" type="sppfs:ObjResultCodeType"
minOccurs="0" maxOccurs="unbounded"/>
</sequence>
</complexType>
</element>
<complexType name="ResultCodeType">
<sequence>
<element name="code" type="int"/>
<element name="msg" type="string"/>
</sequence>
</complexType>
<complexType name="ObjResultCodeType">
<complexContent>
<extension base="sppfs:ResultCodeType">
<sequence>
<element name="obj" type="sppfb:BasicObjType"/>
</sequence>
</extension>
</complexContent>
</complexType>
An <spppAddResponse> contains the elements necessary for the SPPF
client to precisely determine the overall result of the request, and
if an error occurs, it provides information about the specific
object(s) that caused the error.
Cartwright, et al. Standards Track [Page 12]
RFC 7878 SPP Protocol over SOAP August 2016
The data elements within the SPPP over SOAP Add response are
described as follows:
o clientTransId: Zero or one client transaction ID. This value is
simply an echo of the client transaction ID that the SPPF client
passed into the SPPF update request. When included in the
request, the SPPF server MUST return it in the corresponding
response message.
o serverTransId: Exactly one server transaction ID that identifies
this request for tracking purposes. This value MUST be unique for
a given SPPF server.
o overallResult: Exactly one response code and message pair that
explicitly identifies the result of the request. See Section 7.3
for further details.
o detailResult: An optional response code, response message, and
BasicObjType (as defined in [RFC7877]) triplet. This element will
be present only if an object-level error has occurred. It
indicates the error condition and the exact request object that
contributed to the error. The response code will reflect the
exact error. See Section 7.3 for further details.
7.2.2. Delete Operation Structure
In order to remove an object from the Registry, an authorized entity
can send the spppDelRequest into the Registry. An SPPP over SOAP
Delete request is wrapped within the <spppDelRequest> element while
an SPPP over SOAP Delete response is wrapped within the generic
<spppDelResponse> element. The following subsections describe the
<spppDelRequest> and <spppDelResponse> elements. Refer to Section 10
for an example of the Delete operation on each type of SPPF object.
Cartwright, et al. Standards Track [Page 13]
RFC 7878 SPP Protocol over SOAP August 2016
7.2.2.1. Delete Request
An SPPP over SOAP Delete request definition is contained within the
generic <spppDelRequest> element.
<element name="spppDelRequest">
<complexType>
<sequence>
<element name="clientTransId"
type="sppfb:TransIdType" minOccurs="0"/>
<element name="minorVer"
type="sppfb:MinorVerType" minOccurs="0"/>
<element name="objKey" type="sppfb:ObjKeyType"
maxOccurs="unbounded"/>
</sequence>
</complexType>
</element>
The data elements within the <spppDelRequest> element are described
as follows:
o clientTransId: Zero or one client-generated transaction ID that,
within the context of the SPPF client, identifies this request.
This value can be used at the discretion of the SPPF client to
track, log, or correlate requests and their responses. The SPPF
server MUST echo back this value to the client in the
corresponding response to the incoming request. SPPF server will
not check this value for uniqueness.
o minorVer: Zero or one minor version identifier, as defined in
Section 7.4.
o objKey: One or more elements of abstract type ObjKeyType (as
defined in [RFC7877]). Each element contains attributes that
uniquely identify the object that the client is requesting the
server to delete. Refer to Section 7.1 for a description of all
concrete object key types, for various SPPF objects, which are
eligible to be passed into this element. The elements are
processed by the SPPF server in the order in which they are
included in the request. With respect to the handling of error
conditions, conforming SPPP SOAP servers MUST stop processing
ObjKeyType elements in the request at the first error and roll
back any ObjKeyType elements that had already been processed for
that Delete request ("stop and roll back").

explicitly identifies the result of the request. See Section 7.3
for further details.
o svcMenu: Exactly one element of type SvcMenuType that, in turn,
contains the elements to return the server status, the major and
minor versions of SPPP over SOAP supported by the SPPF server
(refer to Section 12 of [RFC7877] for the definition of
SvcMenuType).
7.3. Response Codes and Messages
This section contains the listing of response codes and their
corresponding human-readable text. These response codes are in
conformance with the response types defined in Section 5.3 of
[RFC7877].
The response code numbering scheme generally adheres to the theory
formalized in Section 4.2.1 of [RFC5321]:
o The first digit of the response code can only be 1 or 2: 1 = a
positive result, and 2 = a negative result.
o The second digit of the response code indicates the category: 0 =
Protocol Syntax, 1 = Implementation Specific Business Rule, 2 =
Security, and 3 = Server System.
o The third and fourth digits of the response code indicate the
individual message event within the category defined by the first
two digits.
The response codes are also categorized as to whether they are
overall response codes that may only be returned in the overallResult
data element in SPPF responses or object-level response codes that
may only be returned in the detailResult element of the SPPF
responses.
Cartwright, et al. Standards Track [Page 30]

+--------+--------------------------+-------------------------------+
Table 1: Response Code Numbering Scheme and Messages
The response message for response code 2001 is "parameterized" with
the following parameter: "[Maximum requests supported]". When the
request is too large, this parameter MUST be used to indicate the
maximum number of requests supported by the server in a single
protocol operation.
Response code 2000 SHOULD be used when the XML Schema validation of
requests fails.
Each of the object-level response messages are "parameterized" with
the following parameters: "AttributeName" and "AttributeValue".
For example, if an SPPF client sends a request to delete a
Destination Group with a name "TestDG", and it does not already
exist, then the error message returned should be: "Attribute value
invalid. AttrName:dgName AttrVal:TestDG".
Cartwright, et al. Standards Track [Page 31]
RFC 7878 SPP Protocol over SOAP August 2016
The use of these parameters MUST adhere to the rules defined in
Section 5.3 of [RFC7877].
7.4. Minor Version Identifier
The minor version identifier element is defined as follows:
o minorVer: Zero or one minor version identifier, indicating the
minor version of the SPPP over SOAP API that the client is
attempting to use. This is used in conjunction with the major
version identifier in the XML Namespace to identify the version of
SPPP over SOAP that the client is using. If the element is not
present, the server assumes that the client is using the latest
minor version of SPPP over SOAP supported by the SPPF server for
the given major version. The versions of SPPP over SOAP supported
by a given SPPF server can be retrieved by the client using this
same spppServerStatusRequest without passing in the minorVer
element.
8. Protocol Operations
Refer to Section 7 of [RFC7877] for a description of all SPPF
operations and any necessary semantics that MUST be adhered to in
order to conform with SPPF.
9. SPPP over SOAP WSDL Definition
The SPPP over SOAP WSDL and data types are defined below. The WSDL
design approach is commonly referred to as "Generic WSDL". It is
generic in the sense that there is not a specific WSDL operation
defined for each object type that is supported by the SPPF protocol.
There is a single WSDL structure for each type of SPPF operation.
Each such WSDL structure contains exactly one input structure and one
output structure that wraps any data elements that are part of the
incoming request and the outgoing response, respectively. The
spppSOAPBinding in the WSDL defines the binding style as "document"
and the encoding as "literal". It is this combination of "wrapped"
input and output data structures, "document" binding style, and
"literal" encoding that characterize the Document Literal Wrapped
style of WSDL specifications.
Notes: The following WSDL has been formatted (e.g., tabs, spaces) to
meet IETF requirements. Deployments MUST replace
"REPLACE_WITH_ACTUAL_URL" in the WSDL below with the URI of the SPPF
server instance.

10. SPPP over SOAP Examples
This section shows an XML message exchange between two SIP Service
Providers (SSPs) and a Registry. The messages in this section are
valid XML instances that conform to the SPPP over SOAP schema version
within this document. This section also relies on the XML data
structures defined in the SPPF specification [RFC7877], which should
also be referenced to understand XML object types embedded in these
example messages.
In this sample use-case scenario, SSP1 and SSP2 provision resource
data in the Registry and use SPPF constructs to selectively share the
SED Groups. In the figure below, SSP2 has two ingress Signaling Path
Border Element (SBE) instances that are associated with the Public
Identities with which SSP2 has the retail relationship. Also, the
two SBE instances for SSP1 are used to show how to use SPPF to
associate route preferences for the destination Ingress Routes and
exercise greater control on outbound traffic to the peer's ingress
SBEs.

Example Use-Case Infrastructure
10.1. Add Destination Group
SSP2 adds a Destination Group to the Registry for later use. The
SSP2 SPPF client sets a unique transaction identifier "txn_1479" for
tracking purposes. The name of the Destination Group is set to
DEST_GRP_SSP2_1.

The Registry processes the request and returns a favorable response
confirming successful creation of the named Destination Group. In
addition to returning a unique server transaction identifier, the
Registry returns the matching client transaction identifier from the
request message back to the SPPF client.

10.6. Add LRN
If another entity that SSP2 shares SED (e.g., routes) with has access

TN where the target subscriber has a retail relationship with SSP2,
it first requires an asynchronous bidirectional handshake to show
mutual consent. To start the process, SSP2 initiates the peering
handshake by offering SSP1 access to its SED Group.

11. Security Considerations
The base security considerations of SPPP outlined in Section 9 of
[RFC7877] also apply to SPPP over SOAP implementations.
Additionally, the following must be considered:
SPPP over SOAP is used to query and update session peering data and
addresses, so the ability to access this protocol should be limited
to users and systems that are authorized to query and update this
data. Because this data is sent in both directions, it may not be
sufficient for just the client or user to be authenticated with the
server. The identity of the server should also be authenticated by
the client, which is often accomplished using the TLS certificate
exchange and validation described in [RFC2818].
11.1. Vulnerabilities
Section 5 describes the use of HTTP and TLS as the underlying
substrate protocols for SPPP over SOAP. These underlying protocols
may have various vulnerabilities, and these may be inherited by SPPP
over SOAP. SPPP over SOAP itself may have vulnerabilities because an
authorization model is not explicitly specified in this document.
During a TLS handshake, TLS servers can optionally request a
certificate from a TLS client; that option is not a requirement for
this protocol. This presents a denial-of-service risk in which
unauthenticated clients can consume server CPU resources by creating
TLS sessions. The risk is increased if the server supports client-
initiated renegotiation. This risk can be mitigated by disabling
client-initiated renegotiation on the server and by ensuring that
other means (such as firewall access control lists) are used to
restrict unauthenticated client access to servers.
In conjunction with the above, it is important that SPPP over SOAP
implementations implement an authorization model that considers the
source of each query or update request and determines whether it is
reasonable to authorize that source to perform that specific query or
update.

12. IANA Considerations
This document uses URNs to describe XML Namespaces and XML Schemas.
According to [RFC3688], IANA has performed the following URN
assignment:
URN: urn:ietf:params:xml:ns:sppf:soap:1
Registrant Contact: IESG
XML: See Section 9 of [RFC7878]
