A complex routing protocol that shares information with other routers in order to determine the best path. IS-IS was the first comprehensive link state protocol, and OSPF and NLSP evolved from it.

This post explains what is IP routing and the various Routing protocols - Distance vector (RIP, IGRP) and Link state (OSPF, IS-IS).

Link-state routing protocols were designed to overcome the limitations of distance vector routing protocols. Link-state routing protocols respond quickly to network changes, send triggered updates ...

In recognition of this, the IETF has recently acknowledged that the routing needs of a data center are different than the WAN, and that it’s time to introduce a new routing protocol for data centers.

In this paper, the authors survey the public presentation between two adaptive routing algorithms: Link State Algorithm (LSA), which is centralized algorithm and Distance Vector Algorithm (DVA ...
