Windows Communication Foundation what communication protocols are used to access the service, whether security mechanisms are to be used, and the like. WCF includes predefined bindings for most common communication protocols such as SOAP over HTTP, SOAP over TCP, and SOAP over Message Queues, etc. Interaction between WCF endpoint and client is done using a SOAP envelope. SOAP envelopes are in simple XML form, which makes WCF platform-independent. When a client wants to access the service via an endpoint, it not only needs to know the contract, but it also has to adhere to the binding specified by the endpoint. Thus, both client
Communication protocol monolithic communication protocol, into the first two layers of the communication suite. This model was expanded to four layers by additional protocols. However, the Internet protocol development has not focussed on the principle of layering as mandatory recipe for communication, rather it evolved as a convenient description of modularity and protocol cooperation. A different model is the OSI seven layer model, which was developed internationally as a rigorous reference model for general communication, with much stricter rules of protocol interaction and a rigorous layering concept of functionality. Typically, application software is built upon a robust data transport layer. Underlying this
