Protocol stack of XML Web Services

Question

Explain the protocol stack of XML Web Services.

Answer 1

Web service protocol stack is the protocol stack (that is, a stack of computer networking protocols) which is employed to define, locate, implement, and form Web services interact with one other. The Web service protocol stack usually stacks four protocols:

(Service) Transport Protocol: accountable for transporting messages among network applications and comprises protocols like HTTP, SMTP, FTP, and also the more recent Blocks Extensible Exchange Protocol (BEEP).

(XML) Messaging Protocol: accountable for encoding messages in a general XML format and hence they can be understood at either end of the network connection. Presently, this area comprises such protocols as XML-RPC, WS-Addressing, and SOAP.

(Service) Description Protocol: employed for explaining the public interface to a particular Web service. The WSDL interface format is usually utilized for this purpose.

(Service) Discovery Protocol: centralizes services into a general registry such that network Web services can publish their position and description, and makes it simple to discover what services are accessible on the network. Universal Description Discovery and Integration (abbreviated as UDDI) was intended for this aim, however it has not been broadly adopted.
