Application specific traffic optimization in a wireless link
First Claim
1. A transmitting device comprising:
- a circuit configured to provide packet flows for transmission;
the circuit further configured to associate each of the packet flows with a plurality of control parameters at least including a type of flow, a minimum data rate and a maximum transmission delay;
wherein each packet flow is associated with a retransmission configuration;
the circuit further configured to multiplex a plurality of packet flows; and
the circuit further configured to transmit data of the packets based on a priority value associated with the packets and retransmit the data based on the retransmission configuration of a packet flow of the data.

Abstract
A packet data system such as a TCP/IP network transmits packets containing a variety of data types along links in the network. Packets are transmitted in a stream between nodes interconnected by the links connections which conform to a transport layer protocol such as TCP, UDP, and RSTP, and includes wireless links, which transmit packets using a radio frequency (RF) medium. Typical protocols, however, are usually developed to optimize throughput and minimize data error and loss over wired links, and do not lend themselves well to a wireless link. By examining the data in a packet, performance characteristics such as a port number are determined. The performance characteristics indicate the application type, and therefore, the data type, of the packets carried on the connection. Since certain data types, such as streaming audio and video, are more loss tolerant, determination of the data type is used to compute link control parameters for the wireless link which that are optimal to the type of data being transmitted over the link.
