Wireless Transaction Protocol

A transaction protocol is defined to provide the services necessary for interactive "browsing" (request/response) applications. During a browsing session, the client requests information from a server, which may be fixed or mobile, and the server responds with the information. The request/response duo is referred to as a "transaction" in this document. The objective of the protocol is to reliably deliver the transaction while balancing the amount of reliability required for the application with the cost of delivering the reliability. WTP runs on top a datagram service and optionally a security service. WTP has been defined as a lightweight transaction oriented protocol that is suitable for implementation in "thin" clients (mobile stations) and operates efficiently over wireless datagram networks. The benefits of using WTP include:
