 Description of Working Group:

 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 tool box 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. It may be that a rechartering of the 
 working group occurs before the completion of this milestone.

 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-PR, and RSVP-PR auth-session, will be addressed.

 It is a non-goal of the working group to develop new resource allocation 
 protocols. Resource reservation and traffic engineering are out of scope 
 of this working group. Additionally, third party signaling is out of 
 scope of this working group. Mobility protocols and AAA work are out of 
 scope of the working group. The work produced in this Working Group 
 should work with existing IETF mobility and AAA protocols, including 
 (but not limited to) Mobile IP, Seamoby, AAA, Midcom and RAP. It
 will also welcome participation and expression of requirements from
 non-IETF standards organization members, for instance 3GPP and 3GPP2 
 and ITU-T.
