40G Deduplication Packet Broker

Packet duplication is a potential problem in all large data center networks. While there are many causes of packet duplication, a common cause is networks that are tapped at multiple locations which tend to output duplicate copies of packets. Network Packet Brokers or network monitoring and security tools hence receive multiple copies of the same packet from these tapping points as the packets traverse the network. Removal of duplicate packets in the NPB will therefore significantly reduce processing overhead in monitoring and security tools. 

Garland Technology’s AF10G4ACEV2 is designed to remove all duplicate packets in the ingress stream within a roughly 850mS window, for an average packet size of 128 Bytes and send the de-duplicated packet stream back out the egress direction to a Network Packet Broker. The deduplication function is performed by the advanced packet processor, in conjunction with on-board buffer memory and look-up tables. Removal of duplicate packets reduces significant processing overhead in the monitoring and security tools connected to the network.
