All rights reserved.Cisco ConfidentialNetwork-level Smart Services 3 Machine to Machine Connectivity Over the Internet Proposal Overview  Interface mechanism for communication between remote entities (devices/networks at the customer site, the network vendor backend system, and/or a managing partner backend system) via the Internet.  Meant to be used in conjunction with other mechanism to realize overall, end-to-end connectivity e.g. – A backend application might contact an embedded client at the network/customer site via a chain of transports consisting of a LAN at the backend, XMPP messaging via the internet (this proposal) and another LAN between GW and devices at the customer site – Backend application and embedded client might communicate via a JAVA Message Service (JMS) or Enterprise Service Bus (ESB).

Control, data and signaling are conveyed via XMPP stanzas. – Secure, layer 3 point to point tunnels that are set up between connectivity endpoints using XMPP as the signaling mechanism.  The Protocol Adaptation function (not an integral part of the connectivity), allows endpoints to adapt their communication protocols (e.g. SOAP, syslog, SNMP etc.) to one of the transports supported connectivity. An endpoint might use XMPP for one communication protocol and layer 3 tunneling for another.  Several XMPP protocol adaptations are defined as standard XMPP extension protocols (XEPs). Other extensions can be defined as needed.  On booting, connectivity instances authenticate themselves to an XMPP server. This is followed by authentication, registration and any necessary contract validation with the back end
