Abstract: Techniques for implementing traffic deduplication in a visibility network are provided. According to one embodiment, a packet broker of the visibility network can receive a control or data packet replicated from a core network. The packet broker can then apply a first stage deduplication process in which the packet broker attempts to deduplicate the control or data packet based on one or more interfaces of the core network from which the control or data packet originated, and apply a second stage deduplication process in which the packet broker attempts to deduplicate the control or data packet based on the content (e.g., payload) of the control or data packet.
