Stellar protocol between peers/nodes

bkolobara

I understand that peers exchange XDR messages between each other, but I can't find any information about the order this messages are sent. Is there a document describing how the communication between peers works? Or is my only hope reading the stellar-core implementation?

Also XDR messages must be wrapped before they are actually sent through TCP. What is the end format of a raw TCP message?

Yeah you would have to look in the code but it isn't that bad. There aren't that many messages:
StellarMessage describes how all the messages are wrapped: https://github.com/stellar/stellar-core/blob/master/src/xdr/Stellar-overlay.x
This marshals and unmarshals the messages on the wire: https://github.com/stellar/stellar-core/blob/master/src/overlay/Peer.cpp
