Packet Slicing

Each packet which enters an Accolade adapter is parsed so that various functions can be performed based upon certain header information or other pieces of data. Packet slicing is a function which can be applied to each packet when the host application does not require analysis of all packet data in its entirety. This is often done so the application is not inundated with information it does not need. 

Examples where packet slicing 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.
