Abstract: Methods and devices are provided for regulating traffic on a network. According to some aspects of the invention, if a subscriber's upstream traffic exceeds a predetermined level over a first period of time, the subscriber's quality of service is adjusted without requiring the subscriber to re-register. According to some embodiments, a first token bucket is used to determine whether the subscriber's upstream traffic exceeds the predetermined level over the first period of time. In some such embodiments, the first token bucket is used to control the burst size of another token bucket, depending on the subscriber's upstream traffic during the first period of time.

Abstract: A method is provided in one example embodiment and includes predicting a user average data rate for a cable modem; establishing a minimum bandwidth grant size and a maximum bandwidth grant size for the cable modem based on the predicted user average data rate; receiving from the cable modem a request for a particular amount of bandwidth; performing an overgrant if the particular amount of bandwidth is less than the minimum bandwidth grant size, in which the overgrant comprises granting to the cable modem more than the requested particular amount of bandwidth; and performing an undergrant if the particular amount of bandwidth is greater than the maximum bandwidth grant size, in which the undergrant comprises granting to the cable modem less than the requested particular amount of bandwidth.

Abstract: A method is provided in one example embodiment and includes receiving a first data at a first network element; determining that the first data does not match an entry in an access control list; and sending a first message to a second network element that causes the second network element to enter into a low-power state. In yet another example embodiment, the method can include receiving a second data; determining that the second data matches an entry in the access control list; buffering the second data; sending a second message to the second network element, where the second message causes the second network element to exit the low-power state; and sending the buffered second data to the second network element.
