The Distributed Tracing Working Group invites implementations of the Trace Context Level 2 Candidate Recommendation Snapshot. This specification defines standard HTTP headers and a value format to propagate context information that enables distributed tracing scenarios. The specification standardizes how context information is sent and modified between services. Context information uniquely identifies individual requests in a distributed system and also defines a means to add and propagate provider-specific context information.
