Deduplication for Network Visibility
Network visibility attempts to capture all the packets in the network. Network visibility’s task is to provide required packet streams to various monitoring tools. It may encounter duplicate packets due to overlapping tapping. Duplicate packets increase the data bandwidth and thus force
the monitoring tools dimensioning to be higher. Therefore, eliminating duplicate packets will improve monitoring performance and reduce investment.
This white paper describes both packet comparison and filtering based deduplication methods including their pros and cons.
