XMPP (the Internet Standard eXtensible Messaging and Presence Protocol) Multi-User Chat (MUC) is normally provided by a single server, with clients accessing a MUC Room via their local XMPP servers. This standard approach gives performance and resilience problems when operating over constrained networks.
This paper looks at how federating the MUC service can address these problems. Isode’s approach to Federated MUC as implemented in the M-Link XMPP server is described in the context of evolving XMPP standards, and benefits of Federated MUC for purposes other than Constrained Networks are considered.
