A rendezvous protocol is a
computer network protocol that enables resources or
P2P network peers to find each other. A rendezvous protocol uses a
handshaking model, unlike an eager protocol which directly copies the data. In a rendezvous protocol the data is sent when the destination says it is ready, but in an eager protocol the data is sent assuming the destination can store the data.
Examples of rendezvous protocols include
JXTA
JXTA (Juxtapose) was an open-source peer-to-peer protocol specification begun by Sun Microsystems in 2001. The JXTA protocols were defined as a set of XML messages which allow any device connected to a network to exchange messages and collaborat ...

The Invisible Internet Project (I2P) is an anonymous network layer (implemented as a mix network) that allows for censorship-resistant, peer-to-peer communication. Anonymous connections are achieved by encrypting the user's traffic (by using ...

network address translation (NAT) issues, rendezvous protocols generally require that there be at least one unblocked and un-NATed server that lets the peers locate each other and initiate concurrent
packets at each other.
