What create delay in packet switching?
The main delay in switching is caused by the switch waiting for the entire packet before sending it out. This is called “Store and Forward”. This can be alleviated by setting the switch to use “Cut-Through” switching. Cut-Through may go by other names, such as Fast Forwarding. Usually this is only available on higher end (enterprise class) switches. Switching delay will only ever be a problem if you have MANY switches cascaded together. In a typical environment it is really quite negligable. Where you will typically see delay in when dealing with a WAN. There are several types of delay there. 1. Serialization Delay: This delay is inversely proportional to the link speed. It is the amount of time it takes to place the bits on the trasmission medium. On a 10 kbit link it takes 0.1 sec to place 1k of data on the link. on 1 10 Mbit link, it would tak 0.0001 sec to place the same 1k 2. Propegation Delay: This delay is caused by the fact that nothing happens instantaniously. In any transmiss
