ABSTRACT:
Methods, apparatuses and systems directed to enhanced packet load shedding mechanisms implemented in various network devices. In one implementation, the present invention enables a selective load shedding mechanism that intelligently discards packets to allow or facilitate management access during DoS attacks or other high traffic events. In one implementation, the present invention is directed to a selective load shedding mechanism that, while shedding load necessary to allow a network device to operate appropriately, does not attempt to control traffic flows, which allows for other processes to process, classify, diagnose and/or monitor network traffic during high traffic volume periods. In another implementation, the present invention provides a packet load shedding mechanism that reduces the consumption of system resources during periods of high network traffic volume.
