Overview

TChannel is a networking framing protocol used for general RPC, supporting out-of-order responses at extremely high performance where intermediaries can make a forwarding decision quickly. It is easy to implement in multiple languages, especially JavaScript and Python.

Design Goals

Easy implementation in multiple languages
High performance forwarding path where intermediaries can make forwarding decisions quickly
Request/response model with out-of-order responses so that slow requests don't block subsequent faster requests at the head of the line
Ability of large requests/responses to be broken into fragments and sent progressively
Optional checksums
Ability to transport multiple protocols between endpoints (e.g., HTTP+JSON and Thrift)
