Packet Slicing

Advanced FPGA-based Host CPU Offload

If a host application does not require analysis of all packet data in its entirety, packet slicing is a perfect solution to limit the amount of data that an ANIC adapter presents. Examples where this functionality might be relevant is for traffic engineering, billing or protocol analysis type applications. Packets can be optionally sliced to include no packet data at all (only packet headers) or any arbitrary number of bytes, for example just the first 128 bytes of packet data. Different byte slice lengths can be assigned per port or a single value can be applied to all incoming packets.

IP Fragment Handling 

Fragmented IP packets are identified and processed as if they were a single IP packet. For example, the fragments will be classified as the same flow and will be steered to the same host packet buffer.
