Multiplex tcp requests through Envoy HTTP/2 stack

on YouTube ↗11m

" summary

Envoy now terminates and proxies HTTP/2 CONNECT and can encapsulate raw TCP byte streams as H2 data frames using a TCP connection pool H2 codec, enabling metadata as headers and header-based routing. Multiplexing lets many TCP tunnels share one TLS/TCP connection and avoid repeated TLS handshakes. A server-side HTTP connection manager extracts streams while an internal listener/socket avoids kernel copies by moving Envoy buffers, cutting extra copies. Feature lands in Istio 1.8 and upstreaming continues H2 CONNECT encapsulates raw TCP
