The C based gRPC (C++, Python, Ruby, Objective-C, PHP, C#) https://grpc.io/

Bjorn Svensson ac874c2c83 [core] Add a channel argument to set DSCP on streams (#28322 ) This adds a new channel argument `GRPC_ARG_DSCP` which allows users to create classified gRPC streams with a Differentiated Services Code Point (DSCP) marking on the IP frames. The channel argument is handled on both clients and servers, but currently only on posix based systems. Fixes #17225 Background: In addition to what is already described is #17225, when gRPC is used in telco systems there is often a need to classify streams of importance. There can be multiple hops between two endpoints (e.g. between 2 telecom operators) and some streams that are more important than others (e.g. emergency call related or similar). By marking the IP packets using DSCP the aware routers can make a sound decision of the prioritization. This PR propose to use DSCP as the configuration value since its common for both IPv4/IPv6, an alternative would be to use a config name that includes TOS and Traffic Class. There might be more needed regarding documentation and end2end testing, but there I need some advice.
