Controller-switch interaction is served by standard southbound APIs such as OpenFlow , XMPP
, or ForCES ; however, a similar level of standardization is not available at application-controller northbound interface.
can also serve as a messaging infrastructure for SOAP/WS-* Web services .
Figure 2-7 shows the structure of the security layer of the instant messaging system under the XMPP
- Remote vulnerability checks for SMTP, POP3, XMPP
, IMAP and FTP services that speak plain text and then switch to SSL/TLS.
1) The XMPP
approach: in order to aggregate networked instrumentation based on social rules, our research explored the above-mentioned XMPP
, also known as Jabber (the name of the company that launched it)--an open protocol used for instant messaging.
To support useful services based on the massive information related to these things, several technologies such as REST (representational state transfer) , MQTT (message queuing telemetry transport) [12, 13], XMPP
(extensible messaging and presence protocol) , and CoAP (constrained application protocol)  are being studied for information delivery, message process, and communication protocol.
With the said service-based architecture, the collaborative server or service manager can add or utilize or share media service for seamless collaboration using Web service technologies (SOAP, XML, WSDL, and XMPP
) [5, 6] and smartphones' built-in communication features.
This is a reasonable way of using OpenFlow, although there are other approaches as well (e.g., XMPP
) which are arguably even better because they work at a higher level of abstraction.
This type of social interaction will proliferate with the advent of HTML5 and as more developers use open standards such as XMPP
and public Application Program Interfaces (APIs) to support platform services.
The company had been in stealth mode and expected to release its product, a distributed controller that supports both BGP and XMPP
, next year.
En este sentido Open Cobalt proporciona dos opciones de comunicacion textual, una local, para establecer comunicaciones dentro del mismo espacio y otra externa por medio del protocolo XMPP
(Extensible Messaging and Presence Protocol), tambien conocido como Jabber, pudiendo utilizarse esta ultima a traves de diferentes servidores gratuitos.
UCB bridges together instant messages, chat rooms, and user presence and has demonstrated interoperability with: mIRC, Jabber/ XMPP
, CPOF native chat, web chat, and VMF free text.
