  YANG Groupings for Transmission Control Protocol (TCP) Configuration
                     draft-scharf-tcpm-yang-tcp-02

Abstract

   This document specifies a YANG model for TCP on devices that are
   configured by network management protocols.  The YANG model defines
   groupings for fundamental parameters that can be modified in many TCP
   implementations.  The model extends a base model for TCP clients and
   servers [I-D.ietf-netconf-tcp-client-server].

1.  Introduction

   The Transmission Control Protocol (TCP) [RFC0793] is used by many
   applications in the Internet, including control and management
   protocols.  Therefore, TCP is implemented on network elements that
   can be configured via network management protocols such as NETCONF
   [RFC6241] or RESTCONF [RFC8040].  This document specifies a YANG
   model [RFC6020][RFC7950] for configuring TCP on network elements that
   support YANG data models.  This document extends a base model for TCP
   clients and servers [I-D.ietf-netconf-tcp-client-server].  The model
   focuses on fundamental and standard TCP functions that are widely
   implemented.  The model can be augmented to address more advanced or
   implementation-specific TCP features.  Operational state and
   statistics are outside the scope of this memo.

   Many protocol stacks on Internet hosts use other methods to configure
   TCP, such as operating system configuration or policies.  Many TCP/IP
   stacks cannot be configured by network management protocols such as
   NETCONF or RESTCONF and they do not use YANG data models.  Yet, such
   TCP implementations often also have means to configure the parameters
   listed in this document.  All parameters defined in this document are
   optional.

   This specification is orthogonal to a Management Information Base
   (MIB) for the Transmission Control Protocol (TCP) that has been
