Routers are Computers A router is a computer‚ just like any other computer including a PC. The very first router‚ used for the Advanced Research Projects Agency Network (ARPANET)‚ was the Interface Message Processor (IMP). The IMP was a Honeywell 316 minicomputer; this computer brought the ARPANET to life on August 30‚ 1969. Note: The ARPANET was developed by Advanced Research Projects Agency (ARPA) of the United States Department of Defense. The ARPANET was the world’s first operational packet

(OSPF) routing protocols: The following are advantages of link-state routing protocols (OSPF): * Link-state protocols use cost metrics to choose paths through the network. The cost metric reflects the capacity of the links on those paths. * An LSA exchange is triggered by an event in the network instead of periodic updates. This speeds up the convergence process because there is no need to wait for a series of timers to expire before the routers can converge. * Each router has a complete
