ABSTRACT:
A method for prioritizing IP traffic in a wireless network based on a type-of-service (TOS) identifier is provided. The method includes receiving an IP datagram. The IP datagram comprises an original TOS identifier. An IP message is formed by adding an IP header to the IP datagram. The original TOS identifier is copied from the IP datagram into a duplicate TOS identifier in the IP header.
