SIGNET - New, Extensible Internet Signaling Protocols
The Next Steps in Signaling (NSIS) is a generic IP soft state signaling framework that can be used to provide various signaling services, such as QoS resource reservation setup or firewall configuration in network nodes along the data path of end-to-end communications in IP-based networks. It consists of a generic signaling transport protocol, any number of application-specific signaling protocols. In this project we investigate the protocol performance, robustness, complexity as well as correctness issues in these protocol components through prototypes, simulations and in-depth analysis.
Overview
Originally designed by researchers from Columbia University, University of Goettingen and Siemens, CASP presents a new signaling archicture for generic IP soft state signaling. Unlike RSVP, it separates a general signaling transport mechanism from next-hop discovery and application-specific signaling services. The general signaling transport mechanism, referred as messaging layer protocol, which transparently delivers the actual signaling client data, forms the fundamental basis of next generation signaling in IP-based networks. Due to reuse of existing transport protocols (e.g., TCP, SCTP, UDP), the messaging layer can be used in various scenarios, such as large sizes of signaling data or congested links. The Quality of Service (QoS) client protocol and the firewall/NAT signaling client protocol represents two typical applications demanding signaling. Both the messaging layer and client layer protocols, incorporating RSVP concepts in certain circumstances, are currently being standardized in the Next Steps in Signaling (NSIS) working group of the IETF, under terms of General Internet Signaling Transport (GIST) (which comprises the NSIS Transport Layer Signaling Protocol, NTLP) and NSIS Signaling Layer Protocols (NSLPs).
However, currently these protocols lack a systematic study of their behaviors, performance and complexity. In order to fill this gap, we propose to evaluate the protocol design principles and implementation performance, especiall responsiveness, protocol overhead, robustness and correctness, through prototypes, simulations and in-depth analysis.
We are currently investigating the following issues:
Implementation, simulation and performance evaluation of CASP/GIST, QoS NSLP, NAT/Firewall NSLP.
Diagnostic functionalities for GIST/NSIS
Protocol operations under route changes, mobility and tunneling situations.
