US Patent 10009282 Self-protecting computer network router with queue resource manager

A self-protecting router limits the extent to which its queues can be filled with potentially malicious or otherwise harmful messages received from outside the router, thereby ensuring the queues have sufficient room to accept messages generated internally within the router and are necessary for management and operation of the router. Such routers are, therefore, immune to attack by floods of messages from malicious or malfunctioning network nodes, such as computers, switches and other routers.
