Abstract

There are two mapping relationships between virtual routers and physical platform: many-to-one and one-to-one. When multiple virtual routers that are in identical logic network cohabit a shared router platform of physical network, we propose an Interiorly Fast Forwarding Mechanism (IFFM) based on study of Open Shortest Past First (OSPF) and investigation in generation of FIB. This mechanism is proved in which reducing delay is the yardstick of solving fast forwarding among multiple virtual routers. Its purpose is to eliminate the hops of packet forwarding and to advance the speed of packet transmitting. Meanwhile, this mechanism enhances network robustness by reducing network loss ratio that is caused by single point of failure.
