METHOD AND SYSTEM FOR NETWORK ELEMENT SERVICE RECOVERY
First Claim
1. A method for network element service recovery in a network including a client operative to conduct a session with a frontend server connected to downstream network elements and at least one alternate frontend server connected to alternate downstream network elements, the method comprising:
- detecting by a frontend server of an error in or unavailability of a downstream network element; and
,sending a response code to the client to trigger the client to redirect service to or recover on an alternate frontend server.

Abstract
A method and system for network element recovery are provided. In one form, frontend servers intelligently proxy error or unavailability messages returned by backend servers and simulate frontend server failure. In at least one form, the frontend server also includes intelligence or logic to determine that directing the client to recover service to an alternate system or site would assure better service availability, reliability, and/or quality-of-experience for the client.

6. A method for network element service recovery in a network including a client operative to conduct a session with a frontend server connected to downstream network elements and at least one alternate frontend server connected to alternate downstream network elements, the method comprising:
-
detecting by the frontend server an error in or unavailability of a downstream network element; determining whether element recovery or cluster recovery should be performed; if element recovery is determined, switching over by the frontend server to an alternate downstream network element corresponding to the failed or unavailable downstream network element; and
,if cluster recovery is determined, sending a response code by the frontend server to the client to trigger the client to redirect service to or recover on an alternate frontend server. - View Dependent Claims (7, 8, 9, 10, 11)

12. A system for network element service recovery in a network including a client operative to conduct a session with a frontend server connected to downstream network elements and at least one alternate frontend server connected to alternate downstream network elements, the system comprising:
a control module of a frontend server detecting an error in or unavailability of a downstream network element and sending a response code to the client to trigger the client to redirect service to or recover on an alternate frontend server. - View Dependent Claims (13, 14, 15, 16)
