Method of signaling a message from a peer to another peer

A method comprising:

• at a first signaling instance of a system, receiving a message having been generated by a source peer of a peer-to-peer network and intended for a recipient peer of the peer-to-peer network,
• determining a unique identifier of the recipient peer from the message,
• selecting a second signaling instance among signaling instances present in the system by applying a deterministic function to input data, wherein the input data comprises:
• the unique identifier of the recipient peer, and
• a dataset consisting of respective unique identifiers of signaling instances present in the system,
• if when the second signaling instance is the first signaling instance, sending the message in a communication channel established between the first signaling instance and the recipient peer without involving any further signaling instance of the system,
• if when the second signaling instance is not the first signaling instance, sending the message to the second signaling instance, wherein the second signaling instance is configured to implement the method.
