The Next Steps in Signaling Working Group is responsible for
  standardizing an IP signaling protocol with QoS signaling as the first
  use case.  This working group will concentrate on a two-layer
  signaling paradigm.  The intention is to re-use, where appropriate,
  the protocol mechanisms of RSVP, while at the same time simplifying it
  and applying a more general signaling model.
  
  The existing work on the requirements, the framework and analysis of
  existing protocols will be completed and used as input for the
  protocol work.
  
  NSIS will develop a transport layer signaling protocol for the
  transport of upper layer signaling. In order to support a toolbox or
  building block approach, the two-layer model will be used to separate
  the transport of the signaling from the application signaling.  This
  allows for a more general signaling protocol to be developed to
  support signaling for different services or resources, such as NAT &
  firewall traversal and QoS resources.  The initial NSIS application
  will be an optimized RSVP QoS signaling protocol.  The second
  application will be a middle box traversal protocol.  An informational
  document detailing how Differentiated Services can be signaled
  with the QoS Signaling protocol will be made.
  
  Security is a very important concern for NSIS. The working group will
  study and analyze the threats and security requirements for
  signaling.  Compatibility with authentication and authorization
  mechanisms such as those of Diameter, COPS for RSVP (RFC 2749) and
  RSVP Session Authorization (RFC 3250), will be addressed.
  
  It is a non-goal of the working group to develop new resource
  allocation protocols. Traffic engineering is out of scope of this
  WG. Additionally, third party signaling is out of scope of this WG.
  New mobility and AAA protocols are out of scope of the WG.
  However, the work produced in this Working Group should work with 
  existing IETF mobility and AAA protocols, including (but not limited 
  to)
  Mobile IP, Seanoby Context Transfer, etc.  An applicability statement
  will be written to discuss the applicability of NSIS protocols in 
  mobile
  environments.
  
  NSIS also welcomes participation and expression of requirements
  requirements from non-IETF standards organization members, for
  instance 3GPP, 3GPP2 and ITU-T.
