The Adaptive Packet Filtering feature is a licensable addition to the GigaSMART® engine that can identify patterns across any part of the network packet, including the packet payload. Adaptive Packet Filtering can use this awareness to filter based on packet contents beyond Layer 2, 3, and 4 headers, including URLs, patterns in BitTorrent packets, basic application identification, and specific encapsulation protocols. Operators can use Adaptive Packet Filtering to define custom signatures through regular expressions to match their specific applications. With Adaptive Packet Filtering the signatures can also identify sensitive data and obscure it before forwarding to tools.
Adaptive Packet Filtering can identify, and forward packets based on multiple complex headers and encapsulations, including MPLS, VXLAN, MAC-in-MAC, IP-in-IP (IPv4 and/or IPv6) and others.
