WSP

WSP Wireless Session Protocol

WSP is binary form of HTTP offering HTTP 1.1functionality

Long-lived session, session suspend/resume

Optimized for low-bandwidth and long latency.

Push functions

Asychronized requests

Encoding: the number 0x87A5 (1000 0111 1010 0101)is encoded in three octets.

WTP

WTP Wireless Transaction Protocol

Lightweight transaction protocol Message-oriented, not stream oriented, unlike TCP

WDP

WDP Wireless Datagram Protocol

The WDP protocol operates above the data capable

bearer services supported by any available network. Datagram transport service, a UDP like interface.

Multiplexing and Demultiplexing

Port number addressing Segmentation and reassembly (optional)

Error detection

As a general datagram service, WDP offers a consistentservice to the upper layer protocol (Security, Transactionand Session).

Negative voice - Mohsen Banan

Limited distribution

Door open? entry fee $27,000 Reinvent wheels,analog with WWW, binary form,

not real invention but adoption or customization

WAP is not RFC, global open and accepted. Interoperability: WTPs SAR

Efficiency: mobile browsing limited experience

Alternative? LEAP: The Lightweight and EfficientApplication Protocol
