Packet Filtering

Advanced FPGA-based Host CPU Offload

Monitor Outgoing and Incoming Packets
Each packet can be optionally compared against a number of pre-defined filtering rules. A rule can be defined to trigger on most any L2, L3 or L4 header field(s). The most common fields for filtering rules are IP address (source and/or destination), TCP/UDP port (or a range), protocol, VLAN id and MPLS tag. Rules can be defined so that they trigger on both sides of a bi-directional UDP or TCP session.

Once a packet filter matches, actions such as; drop, U-turn (local retransmit) or steer traffic to a specific host packet buffer can be applied to guide a packet along a desired path.
