Network Layer Protocols Pdf Network Packet Network Congestion It discusses the main services provided by the network layer including packetizing, routing, and forwarding. it also covers topics such as datagram and virtual circuit approaches to packet switching, types of network layer delays and throughput, packet loss, and congestion control mechanisms. Problem: congestion collapse easily leads to congestion collapse senders retransmit the lost packets leading to even greater load and even more packet loss.
Network Layer Pdf Computer Network Internet Protocols Another issue in a network layer protocol is congestion control. congestion in the network layer is a situation in which too many datagrams are present in an area of the internet. congestion may occur if the number of datagrams sent by source computers is beyond the capacity of the network or routers. From a performance standpoint, we study the causes of packet delay and loss in computer network. we identify key architectural principles in networking, including layering and service models. we provide brief introduction history of computer networking. Network layer supervises host to host packet delivery – hosts could be separated by several physical networks data link layer provides node to node delivery, transport layer provides process to process delivery. Understand principles behind network layer services: network layer service models, forwarding versus routing how a router works, routing (path selection), broadcast, multicast.

In this chapter we will look at an ip header and its fields and examine the other protocols that reside on the internet layer. we will discuss ip routing in chapters 5 and 6. The delay required for data to reach a destination and an acknowledgment to return depends on traffic in the internet as well as the distance to the destination. The upper layer protocols that use the service of the network layer expect to receive an ideal service, but the network layer is not perfect. the performance of a network can be measured in terms of delay, throughput, and packet loss.
