متن کاملTransmission of IPv 4 Packets over the IP Convergence Sublayer
IEEE 802.16 is an air interface specification for wireless broadband access. IEEE 802.16 has specified multiple service-specific Convergence Sublayers for transmitting upper-layer protocols. The Packet CS (Packet Convergence Sublayer) is used for the transport of all packet-based protocols such as the Internet Protocol (IP) and IEEE 802.3 (Ethernet). The IP-specific part of the Packet CS enable...
