摘要： The present invention provides a network apparatus in a multi-rate shared medium network and controlling method therefore. The apparatus accesses the shared medium using a contention based shared medium access protocol, wherein said apparatus is able to use a plurality of physical layer rates over the shared access medium. One of the plurality of physical layer rates is set as the rated physical layer rate of the apparatus corresponding to a rated application layer bandwidth. The method comprises the steps of determining the real physical layer rate of the apparatus; and upon detection of the real physical layer rate being lower than the rated physical layer rate, adjusting the real application layer bandwidth of the apparatus to be lower than the rated application layer bandwidth. According to the invention, the shared medium is controlled and managed as a communication resource to prevent one or some faulty CPEs from negatively influencing the application layer bandwidth of normal ones so that the normal CPEs and the network on the whole can work properly under such a condition.

摘要： A method of communication between a transmitter and a receiver over a channel is provided. The transmitter is capable of transmitting packets with multiple data rates, each of which adapts to a respective channel condition with regards to the performance of the communication. The method comprises the steps of, at the level of the transmitter: upon detection of a disappearance of deterioration of the channel condition, transmitting packets with a data rate selected from a group of stable data rates that are stably used before the disappearance of the deterioration but larger than the last data rate before disappearance of the deterioration.

摘要： The present invention relates to a medium access control method for data communication through CATV access network over coaxial cable, wherein the method comprises transmitting downstream data frames from a central device to network terminals in downstream time slots of super frames and receiving upstream data frames from said network terminals to said central device in upstream time slots of the super frames over a same carrier frequency, said super frame being divided into multiple time slots comprising at least one downstream time slot intended for transmitting data frames, and one or more upstream time slots which are assigned respectively by said central device to said network terminals for transmitting upstream data frames, each one upstream time slot being allocable to one network terminal. Advantageously, the data is transmitted through a CATV access network over coaxial cable by using this access control method with guaranteed QoS.
