Switching Networks A collection of nodes and connections is a communications network Information is routed by being switched from node to node

How to Switch the Information? • Circuit switching • Packet switching – Datagram – Virtual circuit

Circuit switching Communication via circuit switching involves three phases: – Circuit Establishment connection oriented – Data Transfer – Circuit Disconnect Circuit Dedicated communication path between two stations Developed for voice traffic (phone; Public Switched Telephone Network (PSTN)) – Delay (and delay variation (jitter)) is guaranteed as required by voice traffic

Circuit switching is inefficient – Channel capacity dedicated for duration of connection If no data, capacity wasted Information is transmitted at a fixed data rate with no delay (except for the propagation delay)

In packet switching, packets are handled in two ways – Datagram – Virtual circuit
![Datagram Theres no preplanned route established before any packets sent connectionless Each packet treated Datagram There’s no preplanned route established before any packets sent connectionless Each packet treated](https://slidetodoc.com/presentation_image/d7e9c9bbbe0203e7862e077a5bf964bd/image-10.jpg)
Datagram There’s no preplanned route established before any packets sent connectionless Each packet treated independently Packets can take any practical route Packets may arrive out of order Packets may go missing Up to receiver to re-order packets and recover from missing packets
![Virtual Circuit A preplaned route is established before any packets are sent • Virtual Circuit A preplaned route is established before any packets are sent](https://slidetodoc.com/presentation_image/d7e9c9bbbe0203e7862e077a5bf964bd/image-11.jpg)
• Virtual Circuit A preplaned route is established before any packets are sent connection oriented – Call request and call accept packets establish connection (handshake) • • • Once route is established, all the packets follow same route Each packet contains a Virtual Circuit Identifier (VCI) No routing decisions required for each packet Clear request to drop circuit Not a dedicated path
