Abstract: Introduces a black box framework for the configuration of network communication protocols dynamically. It divides the function of each layer into new protocols, each of which implements a single function, and implementing them through components. There are five kinds of components: Session, Mux, ConduitFactory, Adapter and Protocol according to the features of their behaviors. The architecture of each component throng are abstracted through three tiers: Conduit, behavior and actor. The architecture of each component is described through patterns to make it more reusable and extensible. This black box framework will be applied to ad hoc emulation system.
