Abstract-The success of a service oriented computing significantly depends on its reliability and availability. To achieve better reliability and availability, any fault of the service oriented computing has to be properly handled. Low performance on handling the service fault becomes the most proliferated challenge on fault handling approaches. In this paper, a priority based fault handling strategy selection approach for fault recovery of SOA (Service Oriented Architecture) is proposed using priority selector and fault handler. This approach starts from fault detection method and select the first priority level strategies promptly and if fault could not be handled by first highest level then fault handler selects the second level or intermediate priority level for average performance. As a final in the worst case, least level strategies are applied to resolve the faulty situation. Through experiment, the correctness of the proposed algorithm and the efficiency of the approach are proved. This approach results better performance and high rate of fault repairing.

“…Many researchers have practiced hybrid strategies rather than optimizing a particular strategy. A hybrid technique with application-level logging and connection replication, named CORAL (A Client-Transparent Fault-tolerant) mechanism is proposed in [53]. CORAL recovers in-process requests and does not require deterministic servers, or changes to the clients.…”

“…CoRAL (Aghdaie and Tamir, 2009) is a fault-tolerance solution for web-based services, which is based on connection replication and application-level logging mechanisms. In CoRAL, the state of the TCP connection is preserved using active replication, where the TCP stacks of both primary and backup server process incoming packets simultaneously.…”

A Design Pattern for Recovering From TCP Connection Crashes in HTTP Applications

HTTP is currently being used as the communication protocol for many distributed applications, supporting business and safety-critical services at a world-wide scale. Despite of their increasing importance, HTTP-based applications are still quite exposed to TCP connection crashes, which can result in huge losses for services users and providers, including financial and reputation losses. Typical techniques for achieving reliable HTTP communication rely on buffering and retransmission of complete HTTP messages, and are quite un-adapted to large messages. Stream-based approaches are more efficient as, after a crash, data transmission can be resumed from where it stopped. However, it is very difficult to know how much data is lost after a crash, as TCP provides insufficient support to obtain this information and none to recover from connection crashes. This makes the design of any stream-based reliability mechanism a significant challenge. In this paper we propose a stream-based solution for reliable HTTP communication that is retro-compatible with existing software. The mechanism is presented as a design solution and relieves developers from explicitly designing recovery code for handling connection crashes, providing a standardized way for building reliable applications. Our experimental evaluation shows that the solution is functional and results in acceptable coding and runtime costs.
