P4 Telemetry collector

As the complexity of computer networks increases to accommodate demand for massive connectivity and cloud services, so does probability fault occurrence surface attacks. Hence need constant monitoring network devices accurate analysis traffic patterns ensure highest performance maximum security. This requires collecting processing telemetry data from many sources in which leads extra bandwidth usage strains CPU at system resulting scalability issues as grows. In this paper, we propose a two-stage postcard collector based on plane programmability using P4 language address issues. We show decrease load server by over 70% while lowering less than 7% most extreme scenario, cost variable delay introduced collection postcards.
