Abstract: Routing is the cornerstone of network architecture , and a new routing mechanism is a requisite for constructing new network architecture . The current routing mechanism of the Internet layer is basically the single next- hop routing mechanism, which is the root of transmission congestion in the network. To solve this congestion problem, a fundamental measure is to change the route selection mode of current routing mechanism to allow parallel transmission over multiple routes . Currently, Border Gateway Protocol (BGP ) is the only inter- domain routing protocol used in the Internet, but the routing system using BGP suffers scalability problem. To solve the scalability issue of the current inter- domain routing system, a new hierarchical routing system, i. e . Scalable Inter- Domain Routing Architecture (s - idra ), is suggested . In addition to scalability, the current routing system is facing other challenges including security, Quality of Service (QoS ), multicasting , mobility and dynamic network topology. Therefore , the res earch on routing protocols , especially the protocol for the new network architecture , is still a tough task and has a long way to go .
