Quizplus · Accepted Answer

A Label Information Base (LIB) is a table maintained by each label switching router that contains the mappings between incoming labels and the outgoing interfaces and labels that should be used to forward the packet. It is similar to a forwarding table used in traditional IP routing, but it includes the additional information needed for forwarding packets based on labels. B) LSP refers to Label Switched Path which is a path between two routers that is specified by labels. C) ECN stands for Explicit Congestion Notification and is a mechanism for communicating congestion between network devices. D) FEC refers to Forwarding Equivalence Class which is a group of packets that receive the same forwarding treatment.
