AE Services provides an AEP connection that establishes and maintains a secure communication channel between AE Services and Communication Manager. This transport service, implemented on the AE Services server and on Communication Manager, tunnels ASAI and call information services messages over TCP/IP, using a proprietary Avaya protocol called Application Enablement Protocol (AEP). The AEP connection is secured via Transport Layer Security (TLS).
An AEP transport connection is a secure TCP/IP connection between the AE Services server and a CLAN or Processor Ethernet connection on Communication Manager. When the transport service starts up, it establishes the Communication Manager/AEP transport connection sessions based on the switch connections administered in the AE Services Management Console.
The Link Bounce Resiliency feature provides increased link reliability to the AEP transport connection. This feature ensures that no messages are lost during an interchange or a short network outage of up to 30 seconds.
One AE Services server can support up to 16 AEP transport connections. The 16 AEP connections provide a redundancy failover capability for configurations that use CLAN or Processor Ethernet connections.
If a CLAN goes down or is not accessible over the network, the traffic is redistributed to the remaining CLANs. This failure should be transparent to the application, provided that the failed CLAN was not necessary to support the message bandwidth required by the application.
If a Processor Ethernet connection goes down or is not accessible over the network, the session is still preserved. As long as it is reestablished within 30 seconds, no data will be lost.
