CORBA request portable interceptors: a performance analysis

Interceptors are a mean to add specific network-oriented capabilities (such as authentication, flow control, caching etc.) to a distributed application which runs over a middleware without changing either the application code or the middleware. However, interceptors could be nonintuitive and this could in turn limit their use on a large scale. We present results of an investigation on CORBA portable interceptors in Java on various CORBA platforms. This study includes the identification of the basic mechanisms provided by an interceptor, of their limitations, a proxy-based technique to overcome some of these limitations and a performance analysis. We also release fragments of Java code used for experiments on Interceptor.
