A system for increasing bandwidth to a communication device, comprising: a packet scheduler; and a transmitter; the system configured to operate the packet scheduler to schedule packets of a service flow onto multiple media access control (MAC) channels forming a MAC channel group before operating the transmitter to send the scheduled packets from an origination device toward a destination device, the packet scheduler waiting a maximum group cross channel skew time for an out-of sequence packet, the maximum group cross channel skew time a maximum of multiple pair cross channel skew times, one pair cross channel skew time associated with each pair grouping of MAC channels configured to be formed from the MAC channel group; and the system configured with a setting to allow only a single channel of the multiple channels of the MAC channel group to carry DOCSIS messages, and to override the setting to share at least some of the channels of the MAC channel group among multiple cable modems while the MAC channel group forms a bonded channel.

An intermediate network element/device intercepts TCP packets/segments from a client and alters them before forwarding them to a server. This facilitates an increase in effective receive window size value over that which is contained in the segments. One aspect alters a TCP segment by replacing the receive window value with a value determined according to a formula and then forwards the segment on to the server. Another aspect alters a scaling factor in a SYN segment and forwards the altered SYN segment on to the server. The server stores the scaling factor to a memory connected thereto and multiplies the scale factor by receive window size values in subsequently received TCP segments. The server uses the product to determine how many segment-bytes to send to the client. The predetermined scaling factor and predetermined formula may both be stored on a memory at the intermediate element for processing thereby.

Method for automatically inflating the receive window size in TCP connections

Multicast management messages associate a channel with one or more multicast groups. The information included in the multicast management messages are combined into a channel association table that may be stored at a CPE device for each of one or more interfaces. The channel association table is used in response to a request for a desired multicast group to select a channel over which the desired multicast group should be delivered. The channel selection is based on a review of the channel association table. If a channel is associated with the desired group, it is selected. If a channel is not associated with the desired group, a channel is selected from a plurality of available channels based on group traffic loading criteria. A multicast message, such as a JOIN, is forwarded to other devices informing them that the desired group should only be sought and/or delivered on the selected channel.
