A New Approach to Name-Based Link-State Routing for Information-Centric Networks

The Link State Content Routing (LSCR) protocol is presented, which supports routing over multiple paths to named content using link-state information. LSCR uses two types of link-state advertisements (LSAs): a Router LSA that contains information about links connected to each router, and an Anchor LSA that carries information regarding a name prefix and the router that advertises being attached to that name prefix, also called an anchor of the prefix. Anchor LSAs are propagated selectively based on a diffusing mechanism. In contrast to prior content routing solutions based on link-state information, LSCR allows routers to establish multiple routes to name prefixes, without requiring each router to know about all the instantiations of each prefix. LSCR is shown to avoid permanent routing loops and to have better performance compared to traditional link-state routing protocols when a name prefix is replicated at multiple sites in the network.
