摘要：

随着CORBA(Common Object Request Broker Architecture)应用范围的扩大和应用程序功能的复杂化,单POA(Portable Object Adapter)在层次化请求处理流程下,已不能满足处理大量突发的客户请求和大数据流量的要求.探讨了提高CORBA吞吐率和扩展POA的策略,提出了引入多POA的机制,测试结果表明,多POA机制可提高系统的吞吐率.

Abstract: With the extension of applying area of CORBA and the rising requirement of the complication of application's function, single POA can not satisfy the demand for handling enormous clients' requests and large amount of data in&out in the process of hiberarchy request management any more. Firstly, a kind of muti-POA mechanism is introduced to enhance throughput of CORBA and extend function of POA policy. Secondly, it is proved that multi-POA is able to enhance throughput by test. And finally, the multi-POA system application is discussed in oil field.
