Unit3 Network Layer Protocols Pdf Internet Protocols Computer Basics – ipv6 addressing – ipv6 protocol network layer services the network layer in the tcp ip protocol suite is responsible for the host to host delivery of datagrams. it provides services to the transport layer and receives services from the data link layer. the network layer translates the logical addresses into physical addresses. Network layer provides support for end to end communication (helps to forward the packets from source to destination) by using routers and switches. network layer manages the quality of services (qos). the service provided by the network layer to the transport layer is called as network service.

In an internet, the goal of the network layer is to deliver a datagram from its source to its destination or destinations. if a datagram is destined for only one destination (one to one delivery), we have unicast routing. if the datagram is destined for several destinations (one to many delivery), we have multicast routing. The services should be independent of the router technology. the transport layer should be shielded from the number, type, and topology of the routers present. the network addresses made available to the transport layer should use a uniform numbering plan, even across lans and wans. The network layer policies. the choice between using virtual circuits and using datagrams affects congestion since many congestion control algorithms work only with virtual circuit subnets.

The icmp is a network layer protocol used by hosts and routers to send the notifications of ip datagram problems back to the sender. icmp uses echo test reply to check whether the destination. • experience has shown that internet nodes don't keep the same ip address for their life time • a network (e.g., an enterprise intranet) will need renumber based on topology change (wholesale reconnection to another isp) • an ipv6 node discovers the need for configuring a new ipv6 address for itself. The document discusses network layer concepts including packet switching, ip addressing, and fragmentation. it provides details on: packet switching breaks data into packets that are routed independently and reassembled at the destination. this allows for more efficient use of bandwidth compared to circuit switching. Arp, rarp, icmp, dhcp 3. network layer introduction the network layer is responsible for the source to destination delivery of a packet, possibly across multiple networks (links). whereas the data link layer oversees the delivery of the packet between two systems on the same network (links), the network layer ensures that each packet gets from its.
