WALRUS is a virtual router made in software that emulates radio modem or controller behaviour within computers running OS LINUX.
WALRUS can handle all functions of a radio modem, including servicing all channels on the interfaces (both serial and Ethernet), however, the only thing it is missing is the radio channel.
WALRUS is particularly beneficial for use in the centres of larger networks, and is usually installed on MServer or MRouter. This provides WALRUS with a great deal of computing power and more RAM memory, and also decreases loading of the radio modem processor.
