Abstract: A network device receives a fragmented packet of an internet protocol (IP) packet. The fragmented packet is subsequently received relative to an initial fragmented packet of the IP packet and includes a first set of tuple information. The network device determines an entry of a hash table associated with the IP packet, based on the first set of tuple information and a fragment identifier (ID) within the fragmented packet. The network device retrieves a second set of tuple information associated with the fragmented packet from the hash table entry, and transmits an indication of the first and second sets of tuple information.

Abstract: Techniques for using policies in an overlay communication network are disclosed. These techniques include deriving a plurality of source tags for a flow relating to an overlay communication network, the plurality of source tags relating to one or more policies for the flow. The techniques further include deriving a tag pointer for the flow, the tag pointer corresponding to all of the plurality of source tags, encapsulating the tag pointer in the flow, and transmitting the flow over the overlay communication network, wherein the tag pointer is configured to be used to identify a plurality of policies for the flow on egress from the overlay communication network.
