Name-based Routing with On-Path Name Lookup in Information-Centric Network

Name-based routing is one of the core ideas in Information-centric network (ICN). In name-based routing, there is a tradeoff between the cost of name announcement and name lookup. Some ICN architectures introduce an efficient way of name lookup but pay high price in name announcement, others cut off most information exchange in name announcement yet introduce heavy burden in name lookup. In order to solve this problem and balance the cost of name announcement and lookup, we propose Name-based routing with On-Path Name Lookup (OPNL). OPNL looks up name prefixes on the path to name's guaranteed destination. It accomplishes distributed name lookup with lighter burden while maintaining little information exchange in name announcement. Results of simulation experiments show that OPNL makes a tradeoff between the cost of name announcement and lookup to have better scalability, eliminates storage overhead and communication overhead compared with prior works and attains even better performance.
