Why WAP doesn't use TCP? terrylee 27-October-2008 11:40:16 AMComments it is not transfer protocol & WAP does use HTTP developed for delivering data across the cellular telephone system and optimized for delivery channels that have low bandwidth. Posted by waqasahmad WAP (Wireless Access Protocol) isn't a transfer protocol like HTTP and it uses complete protocol stack. WAP does use HTTP developed for delivering data across the cellular telephone system and optimized for delivery channels that have low bandwidth. Posted by mariuspaul WAP is not actually a protocol at all, in the sense that HTTP and IP are protocols. In fact, WAP involves multiple protocols and a complete network architecture for delivery of wireless content. These three protocols can be thought of as "glue layers" in WAP: * Wireless Transaction Protocol (WTP) * Wireless Transaction Layer Security (WTLS) * Wireless Datagram Protocol (WDP) WTP provides transaction-level services for both reliable and unreliable transports. It prevents duplicate copies of packets from being received by a destination, and it supports retransmission, if necessary, in cases where packets are dropped. In this respect, WTP is analogous to TCP. However, WTP also differs from TCP. WTP is essentially a pared-down TCP that squeezes some extra performance from the network. Posted by sagitraz |
