    摘要: A cable modem termination system receives a bandwidth request message, and collects information on the basis of the bandwidth request message. Then, time bandwidth size information is generated on the basis of the bandwidth request message and the collected information, and a bandwidth allocation message is generated on the basis of the collected information and the time bandwidth size information. Accordingly, a cable modem termination system can effectively receive data transmitted from a cable modem.
