Service Orientation Architecture is playing a vital role in the middleware and enterprise organizations through its key design principles and there are many benefits of it as well. Loose Coupling between services is one of its design principles that help system or architecture to maintain its efficiency because services are less dependent on each other. Stopping of one service could not affect other service and system but there is a fact that services have less knowledge of other services that’s why services cannot be able to properly communicate with each other and Service Oriented Architecture is totally based on communicative messages between services in order to perform their functionality. This paper provides a basic solution to control the messaging criteria between services. This paper holds the brief description of messaging criteria of services in service oriented architecture by defining the process of message that fulfills the guaranteed delivery of message to its other end while communicating or asking for a service.
