A generic transport layer signaling protocol extension in mobile IPv6 networks

ABSTRACT

Next Steps in Signaling (NSIS) is a more general IP signaling protocol suite for the manipulation of state along paths that are taken by data flows. The protocol suite is split into a generic lower layer denoted as NSIS Transport Layer Protocol (NTLP), and a separate upper layer for each specific signaling application known as NSIS Signaling Layer Protocol (NSLP). This paper addresses the crucial issues on the interaction between the NTLP protocol and Mobile IPv6 protocol. We focus on the state management and the signaling transport mechanisms of the NTLP protocol in "Triangle Routing" and "Route Optimization" scenarios. In particular, we also propose a cross layer signaling flow of our extensions in typical NSIS deployment models. With the deployment models, we evaluate the performance of signaling transport service provided by the NTLP protocol.
