摘要： A data communications system includes a server router (102), such as an access controller gateway, operably coupled to at least one client router (104), such as a base radio controller, by an asynchronous link, such as a LAN (106). The client router forwards data received from the server router and stored in the client router's outbound queue (110) synchronously to a device, such as a mobile station (202). The client router's outbound queue is maintained between a lower queue limit and an upper queue limit so as to both reduce the occurrence of data starvation and reduce the amount of data lost should the mobile station hand off to a new serving site. The server router calculates an optimum average send rate and transmits data in bursts at regular intervals, and adjusts the average send rate in response to changes in the outbound rate of the client router. The client router is state machine driven, and sends flow control messages only when entering a new state so as to reduce the amount of flow control messaging.
