Detailed Description

Bind together a set of IO classes like EmulateSubnet, however, in this case, any OLSR protocol messages which flow through this entity have their hopcount and TTL decremented by a given integer.

TODO: Simulate ETX-measurable loss on link. For this we need only drop HELLO messages to create a situation where the measured ETX for the link will increase.

When used to simulate a cloud, enforce any limit on the number of links connected to that cloud by using a run-time assertion.

Reimplemented from EmulateSubnet.

Forward the given OLSR frame, however, decrement the hop counts in the Packet and in any contained Messages. Note that duplicate packet detection is NOT performed; it is always assumed that the given frame will be forwarded in either direction.
