ABSTRACT:
A method, apparatus, article of manufacture, and a memory structure communicating information, particularly information transferred to and from an Internet host. The apparatus comprises a radio port control unit, comprising a router, and a stub. The router is communicatively coupled to transmit and receive messages with an Internet host and communicatively coupled to a packet forwarding module to accept SU-sourced messages and to provide SU-addressed messages to the packet forwarding module in a first data transfer protocol. The stub is coupled between the router and the packet forwarding module to translate messages from the first data transfer protocol to a second data transfer protocol and to translate messages from the second data transfer protocol to the first data transfer protocol. The method comprises the steps of receiving a data packet having a data payload, determining if the data payload is a loss-sensitive message or a delay-sensitive message, configuring the data packet to indicate that an acknowledge message is required if the day payload is a loss-sensitive message and configuring the data packet to indicate that the acknowledgement message is not required if the data payload is a delay sensitive message, and transmitting the data packet.
