Embodiment Construction

[0036] Embodiments described herein can be applied to networks with redundant deployment of servers to improve recovery time. refer to figure 2 , an example system 100 in which embodiments described herein may be implemented includes a logical client network element A (102) that routinely accesses web services from a server or network element B1 (104). A nominally geographically distributed redundant server or network element B2 (106) (also referred to as a backup or standby redundant server or network element) is also available in the network. It should be appreciated that such standby or redundant servers or standby redundant servers need not exactly duplicate their corresponding primary servers. It should also be appreciated that the configurations shown are examples only. Warping can be achieved very well. Additionally, it should be understood that more than one redundant or backup network element may correspond to the primary network element (such as server B1).

Abstract

A method and system for client recovery strategy to maximize service availability for redundant configurations is provided. The technique includes adaptively adjusting timing parameter(s), detecting failures based on adaptively- adjusted timing parameter(s), and switching over to a redundant server. The timing parameter(s) include a maximum number of retries, response timers, and keepalive messages. Switching over to alternate servers engaged in warm sessions with the client may also be implemented to improve performance. The method and system allow for improved recovery time and suitable shaping of traffic to redundant servers.

Description

technical field [0001] The present invention relates to methods and systems for client recovery strategies to increase service availability in redundant server configurations in a network. While the present invention is particularly directed to, and thus described with specific reference to, the technical field of client recovery policies, it will be appreciated that the present invention may have utility in other fields or applications. Background technique [0002] Such as figure 1 As shown, the redundant arrangement of the system is suitably shown by a reliability block diagram (RBD). As shown, the system 10 shows a redundant configuration, with the system 10 having components arranged in a chain, operating in service. A single module A is connected in series with a pair of redundant modules B1 and B2, B1 and B2 are connected in series with another pair of redundant modules C1 and C2, and C1 and C2 are connected in series with a pool of redundant modules D1, D2 and D3. ...
