Appl. No.:

10/180736

Inventors:

Thomas J. Cloonan - Lisle IL, US
Jeffrey J. Howe - West Chicago IL, US
Kevin P. Urban - Downers Grove IL, US

Assignee:

Arris International, Inc. - Suwanee GA

International Classification:

H04L 12/28

US Classification:

37039542, 370235, 37039543

Abstract:

In a data system, such as a cable modem termination system, different-priority flows are scheduled to be routed to their logical destinations by factoring both the priority level and the time spent in queue. The time that each packet of each flow spends waiting for transmission is normalized such that the waiting times of all flows are equalized with respect to each other. A latency scaling parameter is calculated.

Abstract:

A subscriber login server is used for managing a subscriber login session. The login server is associated with a DHCP server for configuring a premise equipment device and operator-managed device. A subscriber login client at the premise equipment device securely communicates login username and password identifiers to the subscriber login server without using PPP technology. The login server retrieves matching identifiers from a RADIUS server and authorizes service with messages to the DHCP server and the CMTS. The login client can emulate a PPP login client so that a user's interface is similar to a PPPoE client. However, a layer- CMTS can be used instead of a layer- CMTS. In addition, subscriber authentication and accounting using RADIUS are preserved, positive network access control at the CMTS is maintained, and native IP traffic is routed or switched for maximum performance and QoS treatment.

US Classification:

3702301

Abstract:

A token bucket instantiation regulate packets in a traffic flow stream based on a predetermined peak traffic flow rate. The token bucket size is nominally set to zero. An evaluation is made at a device that has received a given packet. The packet is considered conforming and is passed from the device if the token depth of the bucket is zero or greater. The token depth is decreased by the number of byes in the packet that was passed. The token depth is continuously replenished at a predetermined token rate until the predetermined bucket size is attained (the bucket is full). A received packet is deemed nonconforming if the token depth is less than zero; the non-conforming packet is not passed but is processed according to non-conforming criteria. Token bucket instantiations may be implemented in hardware, software or firmware for each traffic flow to regulate traffic to a given user.

Abstract:

TFTP server address, configuration file name and relay agent address contained in a DHCPACK are recorded; the TFTP server address is overwritten with the relay agent address before forwarding. Upon receipt of a TFTP request, a transfer identifier is selected from a pool of available port values, and the source address/port pair and relay agent's address are associated therewith. The relay agent's address and the transfer identifier replace the source address/port pair, and a check is made to determine whether the cable modem is requesting the correct configuration file. Action may be taken if the CM requests an incorrect filename, or if configuration TLVs are incorrect. The relay agent retrieves the TFTP server's address/port pair from the first TFTP data packet received, and associates these with the transfer identifier before returning it to the available pool. The transfer identifier is used to lookup the CM address/port pair.

International Classification:

H04J 1/16

US Classification:

370216, 370486

Abstract:

A DOCSIS set-top gateway device uses multiple embedded cable modems so that one eCM can remained tuned to a frequency being used for a current two-way data session and another eCM can be used to tune to a different frequency. The other eCM that tunes to a different frequency is disabled from operating in the upstream direction to avoid conflict with the two-way eCM in communicating with a CMTS. The eCMs in the DSG are controlled by a client controller that interfaces applications local to the DSG to a central device, such as a CMTS. A message may be sent to a client application requesting content on a traffic flow using a different frequency than the two-way capable sCM. The client controller instructs the upstream-disabled eCM to tune to the different frequency, meanwhile the two-way eCM stays tuned to the current frequency.

International Classification:

H04L 12/403

US Classification:

370449

Abstract:

Different polling rates are applied to high priority BE service flows depending on whether the service flow contains, or is about to contain, traffic packets. A high priority service flow is identified upon boot-up of a user device, and defaults to a slow polling mode. A trigger causes the service flow to be serviced as a fast polling mode. The fast polling mode lasts for a predetermined period of time. If traffic continues at the end of the predetermined period of time, the predetermined period of time is reset so that the fast-polling mode continues until traffic flow on the high priority service flow ceases.
