/*
|
|
* This describes the protocol used by the talk server and clients.
|
|
*
|
|
* The talk server acts a repository of invitations, responding to
|
|
* requests by clients wishing to rendezvous for the purpose of
|
|
* holding a conversation. In normal operation, a client, the caller,
|
|
* initiates a rendezvous by sending a CTL_MSG to the server of
|
|
* type LOOK_UP. This causes the server to search its invitation
|
|
* tables to check if an invitation currently exists for the caller
|
|
* (to speak to the callee specified in the message). If the lookup
|
|
* fails, the caller then sends an ANNOUNCE message causing the server
|
|
* to broadcast an announcement on the callee's login ports requesting
|
|
* contact. When the callee responds, the local server uses the
|
|
* recorded invitation to respond with the appropriate rendezvous
|
|
* address and the caller and callee client programs establish a
|
|
* stream connection through which the conversation takes place.
