Lecture 5 Circuit And Packet Switching Pdf Packet Switching This course is about computer networks, the internet, and packet switching, not about telephone networks and circuit switching. nevertheless, it is important to understand why the internet and other computer networks use packet switching rather than the more traditional circuit switching technology used in the telephone networks. Q: how to connect end systems to edge router? bandwidth (bits per second) of access network? shared or dedicated?. From computer network by tanenbaum a collection of computers and devices interconnected by communications channels that facilitate communications among users and allows users to share. Q: how does a switch decide on which output port (on a link) to place a packet? switches needed? list vc tables for switches 1, 2, 3, and 4. you may make necessary assumptions. vci number typically needs less memory space. per packet overhead is less than that of the datagram model.

This chapter introduces switched networks, focusing on collision domains, lan design, and the role of switching technologies in network communication. Packet switching: hosts break application layer messages into packets forward packets from one router to the next, across links on path from source to destination. Q: human analogies of reserved resources (circuit switching) versus on demand allocation (packet switching)? v consider a circuit switched network with n=100 users where each user is active with probability p=0.2 and when active, sends data at a rate r=1mbps. It is only because of the router’s capability to route packets between networks that devices on different networks can com municate. this chapter introduces you to the router, its role in the networks, its main hard ware and software components, and the routing process itself.
