Adaptive probabilistic packet filtering router and method thereof

摘要

A router is provided. The router includes a packet marking unit that inserts marking information generated based on an address of the router into a packet received by the router, according to a packet marking probability that is dynamically set, and a marking probability determination unit that calculates filtering efficiency of the router, and determines the packet marking probability based on the filtering efficiency. The marking information is used to obtain the address of the router by a device that has received the packet containing the marking information.

主权项

1. A router, comprising:
a hardware processor configured to calculate filtering efficiency of the router; determine a packet marking probability based on the filtering efficiency; and insert marking information generated based on an address of the router into a packet received by the router, depending on the packet marking probability, wherein the marking information is used to obtain the address of the router by a device that has received the packet containing the marking information and wherein the processor calculates the filtering efficiency based on a distance from a transmission source of the packet, available resources of the router, and the number of links of the router.
