Hello Networking Gurus,

I'm trying to search this topic for some time now but still unable to find a good reference. Can anyone tell me about the delay it cause in seconds for a packet send by a node via hub, and a collision occurs. PLease include the time the packet was sent (0 sec) >>> Collsion >>> Packet Drop >>> Collision Avoidance (time backoff) >>> packet retransmission.

If you can provide a good reference it will surely help alot.

Thanks in advance, and a happynew year to all.

Regards,
Aries

Its not as simple sent (0 sec) >>> Collsion >>> Packet Drop >>> Collision.

First off the delay time is random, so no reasonable way to predict that. Also, often it takes more than one iteration of the backoff delay to get the inital packet through. And it all depends on the traffic you are trying to avoid.

A good start is to look at:
CSMA/CD at en.wikipedia.org/wiki/CSMA/CD
