Abstract

Service routing across multiple network domains often requires redirection of service requests. Service request redirection can be achieved with multiple single hop redirection as in Session Initiation Protocol (SIP) or as a single redirection of multiple hops as in Service Network Graph (SNG). For efficiency and manageability, it is desirable to hold all the redirection information and knowledge for service routing in a single entity during redirection of individual service. In this paper, we propose the use of Service Path (SPath) to store and communicate the redirection information and knowledge for better performance. We also discussed how SPath can be applied to access a shared service and perform authentication in a multi-hop inter-domain service routing context using SNG as an example for illustration.
