A routing device including an operating system kernel, a virtual router residing external to the kernel, a router manager configured to manage the virtual router, an application residing external to the virtual router, and a number of physical interfaces is disclosed. The application selectively interacts with the virtual router and the kernel on a dynamic basis, which perform a number of tasks for the application. The virtual router includes a routing protocol stack configured to handle a number of routing protocols, a number of interface drivers configured to communicate with corresponding physical interfaces, an IP stack configured to interact with the routing protocol stack and perform a forwarding function via the interface drivers, the IP stack having a forwarding information table used to perform the forwarding function; and a socket layer having a corresponding socket API configured to facilitate interactions between the IP stack and one or more socket applications.

Method and system for implementing external applications using remote socket application programming interface for virtual routers

Routes between data planes are partitioned according to the source and destination data planes. Partitions are distributed according to the source data plane associated with the partition. Each data plane is configured to clear and resynchronize its own routes when a data plane fails. Also, the restarted data plane is configured to restore routes by retrieving partitions that have the restarted data plane as the source data plane.
