One-To-One Communication

RFC 2810: Internet Relay Chat: Architecture

5.1 One-To-One Communication


   Communication on a one-to-one basis is usually performed by clients,
   since most server-server traffic is not a result of servers talking
   only to each other.  To provide a means for clients to talk to each
   other, it is REQUIRED that all servers be able to send a message in
   exactly one direction along the spanning tree in order to reach any
   client.  Thus the path of a message being delivered is the shortest
   path between any two points on the spanning tree.

   The following examples all refer to Figure 1 above.

   Example 1: A message between clients 1 and 2 is only seen by server
       A, which sends it straight to client 2.

   Example 2: A message between clients 1 and 3 is seen by servers A &
       B, and client 3.  No other clients or servers are allowed see the
       message.

   Example 3: A message between clients 2 and 4 is seen by servers A, B,
       C & D and client 4 only.
