Beta Version Only
Presence Mirror
The Presence Mirror component enables the storage of user presence information in a
database on a near real-time basis. You must have a supported database to use this
feature. The Presence Mirror is included in the developer extensions installation
package.
Router-to-Router connection
The Router-to-Router connection allows a connection between two routers that are
not in the same cluster or subnet.
S2S command processor
See Server-to-Server command processor.
Secure Socket Layer (SSL)
SSL is a TCP/IP standard for supporting encryption at the socket communication
layer.
Server-to-Server (S2S) command processor
The Server-to-Server command processor, configured within a Connection Manager
component, allows Jabber XCP servers to communicate with each other across
domains.
Single Domain Name Support (SDNS)
The Single Domain Name Support component provides a means of distributing the
load for a single Jabber domain over multiple components. For example, if you want
users who are connecting to routers A and B to participate in Text Conference rooms
on either router, you must configure an SDNS component on both routers. The
services that you can configure for SDNS include JSM, InfoBroker, and Text
Conferencing.
The SDNS plugin (new in Jabber XCP 5.2) uses the SDNS component’s default
settings, and is used for specific implementations in which packet ‘to’ and ‘from’
addresses are required. For example, this plugin can be used for SDNS
implementations that use JSM, Text Conferencing, or SIP gateways; however, it
cannot be used with the InfoBroker (as can the SDNS component).
SMTP command processor
The SMTP (Simple Mail Transfer Protocol) command processor, configured within a
Connection Manager component, redirects IM messages that are sent to offline users
to an email server. The users then receive the messages via email.
Stanza Optimizer
The Stanza Optimizer component implements Extended Stanza Addressing
(described in detail in XEP-33). You can configure the Stanza Optimizer to work in
conjunction with the InfoBroker and Text Conferencing components in order to
