Switching Techniques - In large networks there might be multiple paths linking sender and receiver. Information may be switched as it travels through various communication channels. There are four typical switching techniques available for digital traffic.

 You are familiar with the-concept of switching. Circuit switching is the study of data link layer. The services of networks are provided by using the concept of packet switching.

Circuit switching is a switching method in which a dedicated communication path in physical form between two stations within a network is established, maintained and terminated for each communication session. It has basically three phases as circuit establishment, data transfer and circuit disconnect.

Conceived in the 1960's, packet switching is a more recent technology than circuit switching which addresses a disadvantage of circuit switching: the need to allocate resources for a circuit, thus incurring link capacity wastes when no data flows on a circuit.

1   A message is a logical unit of information and can be of any length.

  1. In message switching, if a station wishes to send a message to another station, it first adds the destination address to the message.
  2. Message switching does not establish a dedicated path between the two communicating devices i.e. no direct link is established between sender and receiver.

• PPP was devised by IETF (Internet Engineering Task Force) to create a data link protocol for point to point lines that can solve all the problems present in SLIP.

• PPP is most commonly used data link protocol. It is used to connect the Home PC to the server of ISP via a modem.

Cell switching is associated with Asynchronous Transmission Mode (ATM) which is considered to be a high speed switching technology that attempted to overcome the speed problems faced by the shared media like Ethernet and FDDI. Cell switching uses a connection-oriented packet-switched network.

Time space switching:- A time space (ts) switch takes the outputs of several time-division switches, for example, TSI switches and connects them as inputs as a space division switch. The effect of this paired arrangement is that packets can be swapped between different output lines.

Datagram is better if numbers of packets are not very large. As it is a connectionless service there is no need to prior call set up. Therefore, It is more flexible and provides alternate route to avoid the congested part of the network.

A circuit is a path between two or more points along which an electrical current flows. In data communication, we may consider a circuit as a specific path between two or more points along which signals can be carried. The signals may be analog, binary or digital. It has been shown in the Figures, wherein the link between PC and modem, link between modem and CTO and so on constitutes a circuit.
