Redundancy Support
The following topics describe the redundancy support for the CSTA Connector:
Redundancy Support Feature Overview
BroadWorks Connector operates in unison with the generic Connector T-Server in order to provide a high availability (HA) solution. The HA deployment configurations are shown below.
The main features of this solution are:
- Connector T-Servers runs as a standard Genesys HA pair.
- BroadWorks Connector operates independently of other Connectors, it does not synchronise information in the same manner as the T-Server HA pair.
- BroadWorks Connector maintains redundant links to the BroadWorks switch independently of the Connector T-Server.
- BroadWorks Connector is able to support multiple T-Server connections.
BroadWorks Connector Operation
BroadWorks Connector supports connections to multiple XSP servers. BroadWorks Connector uses multiple Event Channels, and each Event Channel is given equal weight. BroadWorks CTI balances the event reporting across all the Event Channels. If one of the Event Channels fails, BroadWorks CTI continues to serve the event subscription over the remaining Event Channels adjusting the load accordingly. BroadWorks Connector initiates its link recovery procedure to re-establish a failed connection.
Connector supports multiple T-Server connections. T-Servers may or may not start monitors for the same set of devices, Connector filters the events and requests for each connection against their respective start monitor requests.
Connector responds to SystemStatusRequests from T-Server indicating overall status of links, and reports a failure if all links are down.
