Abstract
Classifying packets is disclosed. In some embodiments, a packet can be classified once for a plurality of nodes. The classification of a packet can be used at a receiving node to determine the receiving node policy for the packet. In some embodiments, the classification of a packet is specified by a classification index associated with the packet. In some embodiments, the receiving node policy for the packet can be determined by performing a lookup in a data structure associated with the receiving node based at least in part on the classification index of the packet. In some embodiments, the classification of the packet is sufficient to specify not only the receiving node policy but also a plurality of policies of a plurality of nodes.
