In-band Network Telemetryを用いたネットワーク監視方式の一考察

This document explains how the power of the P4 language and Field Programmable Gate Arrays (FPGAs) can be combined to achieve unprecedented time to market in the high bandwidth networking domain. Netcope P4 to FPGA Compiler (Netcope P4) is used to generate a 100 Gbps network probe for datacenter traffic carrying In-band Network Telemetry (INT) headers. While the original traffic (with INT headers stripped away) is forwarded to its destination at wire speed, INT headers are processed, stored and visualized by the Flowmon Collector, a leading commercial platform for network traffic analysis and visibility. The final solution is a clever mix of hardware-accelerated probe and mature network monitoring software, all put together with no need for HDL coding.
