Typically, these network devices talk to each other using different control protocols to find the best network path. The purpose of building such network controls is to provide a reliable data transport for network endpoints. These network endpoints are servers and workstations. When a network endpoint sends a packet (data), it is switched by these network devices based on the best path they ...
