Routing protocols implement algorithms that tell routers the best paths through internetworks. Routing protocols include Border Gateway Protocol (BGP), Interior Gateway Routing Protocol (IGRP),...
The STP protocol allows switches to have redundant connections, while avoiding problems associated with switching loops. For example, if there is a switching loop, a broadcast would go around in...
That means that if an IP packet is sent, there is no guarantee that it will arrive. If it doesn't arrive, IP will do nothing to re-send it. If it is necessary to re-send lost packets, higher-level...
