Question

There are three main classes of MAC protocols: channel partitioning, random access, and token ring. Use the Internet search to describe briefly (max 5 sentences) each of these MAC protocols.

Answer 1

hi,

I am happy to help you with this question.

Mac is an abbreviation of media access control.

Here we have to see the main 3 protocols.

• Channel partitioning.
• Random access.
• token ring.

So let us first describe Channel partotioning.

Channel Partitioning: It is a time division based channeling access.

In this we access the location on the basis on time and in multiple rounds.

Each station gets divides into length in each round and the used slots are idle.

It can be subdivided into 2 sub categories : frequency based and time based .

example:6 station LAN.

Random access protocol: It works to find the collisions in the transmitting nodes.

It studies how to detect collisions and how to recover from  it.

If there are 2 or more transmitting nodes then it may be in a state of collision.

Example: ALOHA ,slotted ALOHA.

It is basically due to no prior coordination between nodes.

Token Ring: this protocol is used to define the order in which stations are send .

The stations are connected with each other by using a technology called rings.

it does the functioning by using a 3 byte frame called tokens.

these tokens are traveled in a ring structure and uses token access mechanism .

It creates a token channel accessing provides a fair chance to all the stations .

Thank you.

I hope i was able to help you with this question .If you have any queries please be comfortable to ask in the comment section i will be happy to help you.
