Core routers, also known as "backbone routers," are routers located at the center of the network. A router located at the edge of a network is called an access router. Core routers and edge routers are relative concepts. They all belong to routers, but have different sizes and capacities. The core router of one layer is the edge router of another layer. This standard specifies the testing methods for interface characteristics, ATM protocol testing, PPP protocol testing, TCP/ITP protocol testing, routing protocol testing, multicast protocol testing, MPLS and MPLS VPN function testing, network management testing, performance testing, reliability testing, and other aspects of core routers. This standard applies to core routers that support the IPv4 protocol. 2 Normative References: The clauses in the following documents become clauses of this standard through reference in this standard.
