Cassandra Network Protocols

When you submit a write request with a constancy of EACH_QUORUM, what network protocol does Cassandra use to write the data to the other DCs? 


Similarly, what network protocol does Cassandra use when writing data as part of replication?

Hand rolled headers and binary serialisation over TCP. 

See o.a.c.net.IncomingTcpConnection for the starting point for an incoming  connection.
