A routed protocol is any network layer protocol that provides enough information in its network layer address to allow a packet to be forwarded from one host to another host based on the addressing scheme, without knowing the entire path from source. Whilst both tcp and udp protocols use the same range of port numbers, due to the difference in protocols the two similarly numbered ports on each protocol are seen as distinct ports.

Networking protocols southeastern louisiana university. Properly working routing protocols can help your network become more adaptable, therefore making your job a lot simpler. Routing algorithm if endpoints are within same co, directly connect if call is between cos in same lec, use onehop path between cos otherwise send call to one of the cores only major decision is at toll switch onehop or twohop path to the destination toll switch why dont we need longer paths. Lan protocols operate at the physical and data link layers of the osi model and define communication over the various lan media. Common protocols 63 process is a clientserver communication type in which the client computer requests an ip address from a dhcp server and the server acknowledges it by giving it one. Bgp speakers communicate across tcp and become peers or neighbors. Top 5 network routing protocols explained lifewire.
It is important to make sure that all systems on the network are configured. There are no dead ends other than destination there are no loops. Each as designates a border router to speak on its behalf. To a better understanding of what ip routing is, lets get acquainted with the basic terms.
