Abstract:
1. A system of virtual router domains comprising: a host router running a common operating system and a master control processor implemented in virtual networking (v-net) domains capable of separating routing tables used internally from externally visible routes; the host router having a capability of running plural independent processes and routing application copies corresponding to the independent process, but sharing said common operating system; each of at least a subset of said v-net domains running DRP and SNMP processes, and establishing virtual routers, thereby establishing said v-net domains by ones of said independent processes, the v-net domains logically partitioned into ones of said v-net domains within said host router, each said v-net domain having a unique v-net domain ID address and an independent replica array of all global variables across said common operating system, each said process running in a said v-net domain independently of all other said v-net domains on top of said common operating system; and said global variables being accessed by macro references in each said v-net domain.
