public class DelayChannel extends ErasureChannel
A speed equal to Infinity (the default) results in no propagation delay. If the loss probability is greater than zero then on each call to the transmit() method, for each receiver in range, with the specified probability, the transmission to that receiver will not occur. Whether a transmission occurs to a particular receiver is independent of whether it occurs to any other receiver.

If the lossProbability is zero, (the default) then the specified receiver will receive the token if it has room. If lossProbability is greater than zero, the token will be lost with the specified probability, independently for each receiver in range. Note that in this base class, a port is in range if it refers to this channel by name and is at the right place in the hierarchy. This base class makes no use of the properties argument. But derived classes may limit the range or otherwise change transmission properties using this argument.
