Detailed Description

Csma Channel.

This class represents a simple Csma channel that can be used when many nodes are connected to one wire. It uses a single busy flag to indicate if the channel is currently in use. It does not take into account the distances between stations or the speed of light to determine collisions. Optionally, it allows for full- duplex operation when there are only two attached nodes. To implement full-duplex, we internally keep two TX "subchannels" (one for each attached node). When in half-duplex mode, only the first subchannel is used.
