Explanation

In the Cisco Expressway XMPP federation architecture, the Expressway-E is the edge component deployed in the DMZ that faces the public internet. It is responsible for establishing and terminating the XMPP federation connection to remote (external) federation servers. The Expressway-C is the internal traversal component that communicates with the IM & Presence server inside the enterprise network, but the actual outbound/inbound federation connection to the remote partner's server is handled exclusively by the Expressway-E. The IM & Presence Server and CUCM Publisher do not directly participate in external federation connections.
