Abstract:
A network device may be configured to filter network traffic using multiple different filters bound to different interfaces of the network device. The network device may include logic to identify a relationship map that describes a topology of bind-points associated with the network device. Additionally, the network device may include logic to generate a merge graph based on the relationship map, the merge graph including one or more nodes, where each node represents a walk through the relationship map and includes one or more merge-points, where each merge-point is defined as a filter associated with a bind-point. The network device may also include a ternary content-addressable memory (TCAM) programmed to include entries based on the nodes of the merge graph.
