Whats the difference between Lightstreamer and Jabber/XMPP?
The term Jabber is widely used to refer to a set of open protocols for streaming XML elements between any two points on a network, and to the technologies built using those protocols. The Extensible Messaging and Presence Protocol (XMPP) is the IETF’s formalization of the base XML streaming protocols for instant messaging and presence developed within the Jabber community. XMPP is usually implemented via a client-server architecture wherein a client utilizing XMPP accesses a server over a TCP connection on port 5222. In addition to the base protocols, there exist several extensions specified in the “JEP” series, including two methods for using HTTP connections instead of plain TCP sockets: HTTP-Polling (JEP-0025) and HTTP-Binding (JEP-0124). Anyway, none of these extensions support asynchronous streaming, since they are based on periodic requests from the client to poll the server for incoming “stanzas” (i.e. XML discrete semantic units of structured information). This implies that Jab
