Rendezvous protocol

Rendezvous Protocol is a way for two computers to find each other on the internet so they can talk to each other. It's like two friends trying to meet in the park – first, one friend tells the other where they will be, and then the other friend comes to that spot at the agreed time. Similarly, a computer running a Rendezvous Protocol tells another computer where it can be found, like an address or phone number. The other computer then visits that address or dials the number, allowing the computers to connect and communicate.
