INTERNET PROTOCOL ADDRESS IPv4/IPv6 BASED PACKET FILTERING IN WoWLAN MODE

摘要

One embodiment of the present invention provides a system configured to apply Internet Protocol (IP) address based packet filtering prior to entering Wake on Wireless LAN (WoWLAN) mode. During operation, the system receives a request to enter WoWLAN mode. In response to this request, the system collects a set of active IP addresses, as well as a set of active ports. Next, the system filters out packets destined to IP addresses that are not members of the set of active IP addresses, and ports that are not members of the set of active ports. Finally, the system enters WoWLAN mode.
