US Patent:

7272144, Sep 18, 2007

Filed:

Jun 26, 2002

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.

US Classification:

725/111000, 370/216000, 714/011000

Abstract:

In a cable data system that includes a cable modem termination system or CMTS, high-reliability is accomplished by reducing the time required to switch over traffic from a failed circuit to a back up circuit. Fault recovery time to switch over to a spare circuit is reduced by copying the operational parameters used in each of the active circuits into a spare circuit such that upon the failure of an active circuit, the spare circuit needs only to be instructed which set of operational parameters for a particular failed circuit to use. Clock counters that are continuously incremented in active circuits can be copied into a newly installed circuit by copying into a local register for the newly installed circuit, a future value of a clock counter. At a predetermined instant, preferably just before the clock counter value equals to the future value, the future value is clocked into the newly installed circuit so as to synchronize the clock counter value in the new circuit to the clock counter values in the previously activated circuits.

US Classification:

370229000, 370252000

Abstract:

A long-term usage profile and a congestion state metric are used to determine QoS treatment to apply to packets corresponding to a given network user. A user's historical long-term use, measured over one or more periods of time, is used to generate a profile that is compared to one or more predetermined usage threshold level(s). If the usage profile, either singular or composite corresponding to whether one or more than one measurement is used respectively, exceeds the threshold(s), QoS treatment is applied to service flow bytes according to the comparison results during times of network channel congestion. Congestion metrics are determined based on a count of the number of bytes dropped during a congestion measurement window. Either the count itself or the count rate of change combined with the count are compared to a congestion threshold. If the measured/derived values exceed a congestion threshold, the channel is deemed congested.
