Tracing HTTP/2 Traffic Using gRPC Tapping Filter with Hardware Acceleration

Explore a conference talk on implementing gRPC tapping filters with hardware acceleration for tracing HTTP/2 traffic in microservice architectures. Delve into the challenges of using tapping filters with Envoy for monitoring upstream and downstream traffic, especially in TLS scenarios. Examine the bottleneck issues in Admin streaming and the potential throttling of XDS updates. Learn about the proposed solution of streaming gRPC Sink for transport socket level tapping, which aims to provide traffic counters and a ConnectionInfo cache replay mechanism. Discover how memory copy lib can be utilized to offload intensive memory copy operations to hardware accelerators, enhancing overall performance in high-traffic environments.
