Web service protocol stack:
A web service protocol is a protocol stack that is used to define, locate, implement, and make Web services interact with each other.
A web service protocol stack consists of following four protocols:
- Transport Protocol: It is responsible for transporting messages between network applications and includes protocols such as HTTP, SMTP, FTP etc.
- Messaging Protocol: It is responsible for encoding messages in a common XML format so that they can be understood at either end of a network connection. It includes the protocol such as XML-RPC, WS-Addressing, and SOAP.
- Description Protocol: It is responsible for describing the public interface to a specific Web service. It includes WSDL (Web Service Description Language).
- Discovery Protocol: It is responsible for providing a way to publish and find web services over the web. It includes UDDI (Universal Description, Discovery, and Integration).
