Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0031] figure 1 It shows the process of the client proxy gateway memorizing repeated RPC calls in the known technology.

[0032] In the same DCOM application system, repeated RPC calls occur frequently. Repeated calls here refer to calls to the same remote procedure, including the same calling parameters. During these recurring RPC calls, there are a certain amount of calls whose return value does not change. Memorize and save the relevant information of these calls that are repeated and return the same value. This stage is called the learning stage. .

[0033] figure 2 It shows the process of reducing an RPC call across the wide area network by the proxy gateway of the client in the present invention.

[0034] After learning for a period of time, when repeated RPC calls occur again, the agent can directly reply to the RPC call without initiating a cross-WA...

Abstract

The invention relates to a method for accelerating a DCOM system, for reducing interaction number of a wide area network using DCOM according to an inherent law of DCOM, so as to enhance DCOM transfer efficiency, comprising the steps of: analyzing all DCOM transfer request with proxy; if corresponding information has been stored in a client proxy gateway, answering the request directly from the client proxy gateway for query operation of a component support interface; if corresponding information has been stored in a client proxy gateway, answering the request directly from the client proxy gateway for query operation of DISPID of a component support interface method; analyzing all DCOM transfer answers with proxy, discarding an answer when the transfer thereof has been acted by the client proxy gateway.

Description

technical field [0001] The invention relates to a wide-area network acceleration technology, in particular to a method for accelerating a DCOM system by learning DCOM calling rules in the network and caching a small amount of data to reduce the number of DCOM calling interactions between networks. Background technique [0002] DCOM (Distributed Component Object Model) is an RPC-based distributed component object model introduced by Microsoft that can communicate between networks. At present, DCOM technology has been widely used. While DCOM brings many conveniences, due to the reasons of DCOM itself and third-party libraries, DCOM applications inevitably introduce certain redundancy and inefficiency. [0003] Based on DCOM technology, the original RPC call that only needs one time will trigger several related calls. In this way, the delay of a DCOM call initiated to complete a certain function on a high-latency network will increase exponentially. Contents of the inventio...
