WAP and Packet Formats

Question:
Let’s say a WAP server has a WAP stack of the following layers:

  1. Connectionless WSP
  2. UDP
  3. IP

Would you give me example packets that arrive at the server from a WAP-enabled phone requesting a file, say “index.wml,” and the packets that respond to this request?

Answer:
WSP is the session layer protocol.
WTP is the transaction-oriented protocol.
WDP over IP is UDP/IP and is the datagram protocol.
