摘要: A method includes determining addresses, determining masks, and storing the masks in a ternary content-addressable-memory for matching a candidate address to the masks to determine matches to the addresses. The addresses include an address width and positions, the address width equal to the number of positions. Each mask matches one or more addresses, includes a mask width equal to the address width, and includes matching criteria for determining whether to filter a given address. The matching criteria includes a matching component specifying that an identified position in the address includes a particular value or a wildcard component specifying that an identified position in the address is to be ignored. The masks include at least one mask with a wildcard component. The number of masks is less than the number of the addresses. The number of possible addresses corresponding to the masks is equal to the number of the addresses.

摘要: According to one embodiment, a method may include assigning a virtual local area network (VLAN) ingress connection identifier (iXid) to a frame upon ingress. The method may also include classifying a traffic flow for which the frame is a part through ingress engines of the network element based on the iXid. The method may further include swapping the iXid for an egress connection identifier (eXid) in the frame. The method may additionally include policing or shaping the traffic flow based on at least one of the iXid and the eXid. Moreover, the method may include classifying the traffic flow through egress engines of the network element based on the eXid.
