222 © 2002, Cisco Systems, Inc. All rights reserved. Agenda Problem statement: IM&P systems are being deployed by enterprises and carriers. The network effect of those communities is severely limited by the number of participants. There is no current standard for server-to-server connectivity. This is driving further adoption of proprietary public networks (which are quickly becoming the PSTN of IM&P) and slowing the penetration of both XMPP and SIMPLE based solutions. Quick update: XMPP standards progress, implementation, adoption SIMPLE standards progress, implementations, adoption Business Needs: Proposal: Search for a consensus position with respect to an interop profile/protocol for server to server IM&P communications with the intent to drive that position to a standard.

333 © 2002, Cisco Systems, Inc. All rights reserved. SIMPLE and Jabber: better together? Combined “Super Clients” has a SIP UA can act as minimal XMPP host self-test through well-known XMPP host runs as regular XMPP node when behind a firewall or NAT security provided by immediate sending of thread IDs

444 © 2002, Cisco Systems, Inc. All rights reserved. Using the fewest intermediaries possible client to client (client host) client client primes its host before host will receive its messages client (host client) (client host) (host client)

555 © 2002, Cisco Systems, Inc. All rights reserved. Interop between SIP+XMPP hosts and today’s Jabber nodes SIP+XMPP host acts as SIP UA and an XMPP host. Buddy list management and basic presence are handled on behalf of Jabber nodes. Sessions of messages terminate on the Jabber host, and then relay through to Jabber nodes Jabber nodes rely on buddy lists to authorize incoming messages.
