Research on the Routing Algorithms of Fabrics in Terabit Router

Terabit router will play a more important role in the future broadband network.As the core of the terabit router,large capacity and high performance switching fabric is one of key technologies to implement terabit router.The performance of the switching fabrics largely depends on the properties of the routing algorithms.In this paper,the issues in designing the routing algorithm in fabric are surveyed,including state information,routing strategies,deadlock and livelock freedom,quality of service routing and fault tolerant routing.Finally,future trend of the routing algorithms is presented,with a focus on QoS provision in the routing algorithms.
