Chapter 4 MAC Sublayer By Dr.Ju Wang CMSC506, 2005 What is MAC Network assumption: Broadcast channel One channel, many stations Competition, interference among stations.

Slotted ALOHA is twice as efficient as pure ALOHA. Low load wastes slots, high loads causes collisions . Efficiency up to 1/e (37%) for random traffic models.

The layer 2 managed switch operate on the data link layer.These switches act as bridges, where they interconnect networks on its media access control (MAC) sublayer. Layer 2 switches build tables for transferring the frames among networks. Ethernet switches are the most common types of layer 2 switches known to us. The devices connected in the Ethernet network possess a hardcoded MAC address. These MAC addresses generally do not change.
