Prefix-based fat flows

Abstract:

A network device includes one or more processors configured to use a fat flow rule that specifies at least one of a mask to be applied to source Internet protocol (IP) addresses or to destination IP addresses, or that source ports or destination ports are to be ignored. The one or more processors may further be configured to receive packets having different source or destination IP addresses and/or different source or destination ports, and nevertheless assign the packets to the same fat flow according to the fat flow rule, e.g., by masking the source or destination IP addresses and/or ignoring the source or destination ports of the packets. In this manner, the network device may aggregate two or more different flows into a single fat flow.
