Method For Reducing Interference From Initializing Network Devices In A Data-Over-Cable System

View page
US Patent:
6940874, Sep 6, 2005
Filed:
Nov 30, 2000
Appl. No.:
09/727069
Inventors:
Chester A. Ruszczyk - Medford MA, US
David Willming - Palatine IL, US
Assignee:
3Com Corporation - Marlborough MA
International Classification:
H04L012/00
H04J003/06
US Classification:
370516, 370458, 725114, 725117, 725144, 725148
Abstract:
Methods for reducing interference from initializing network devices in a data-over-cable system. The method includes aligning Initial Maintenance intervals for multiple upstream channels of the data-over-cable system. A cable modem termination system determines if usage intervals for the upstream channels may accommodate Initial Maintenance intervals that start at a common time. If so, the cable modem termination system constructs Bandwidth Allocation MAP messages for the usage intervals that contain Initial Maintenance intervals timed to start at the common time. In response to the MAP messages, initializing network devices range when there are no scheduled data transmissions on any upstream channel. The method may shorten a cable modem's time for ranging and may decrease collisions with data transmissions on the upstream paths when cable modems try to initialize.

Local Area-Networked System Having Intelligent Traffic Control And Efficient Bandwidth Management

US Patent:
7529263, May 5, 2009
Filed:
Jan 16, 2003
Appl. No.:
10/345870
Inventors:
Carlton J. Sparrell - Marblehead MA, US
Alexander D. Vasilevsky - Westford MA, US
Chester Ruszczyk - Acton MA, US
Jinyou Zhang - Woburn MA, US
Assignee:
Ucentric Systems, Inc. - Maynard MA
International Classification:
H04L 12/64
US Classification:
370437, 709203
Abstract:
A centralized interactive TV recording and reproduction system linking several “Quality of Service” (QoS) reproduction and control units (such as television and audio reproduction receivers), as well as high bandwidth non-QoS legacy devices such as PCs, via a Home Area Network (HAN) to a centralized media server, has novel traffic control to prevent non-QoS devices from establishing and maintaining high-bandwidth network connections during the real-time transmission of media (video and/or audio) information from the media server to the QoS devices. In the preferred embodiment, the media server also contains a gateway device for connecting the HAN to a Wide Area Network, Metropolitan Area Network, and/or the Internet, and the media server also receives video and audio signals from sources such as cable, satellite, terrestrial broadcast, etc. The media server also contains a network router. All traffic from non-QoS devices is routed through the media server, and the media server limits the delivery of packets sent from source non-QoS devices to destination non-QoS devices.

System, Device, And Method For Contention-Based Reservation In A Shared Medium Network

View page
US Patent:
59600004, Sep 28, 1999
Filed:
May 30, 1997
Appl. No.:
8/866865
Inventors:
Chester A. Ruszczyk - Chicago IL
Whay Chiou Lee - Cambridge MA
Imrich Chlamtac - Dallas TX
Assignee:
Motorola Inc. - Schaumburg IL
International Classification:
H04L 12413
H04J 316
US Classification:
370447
Abstract:
A system, device, and method for contention-based reservation in a shared medium network resolves collisions resulting from contention access using a combination of probabilistic tree splitting and first-come-first-served splitting techniques. The collision resolution procedure utilizes the first-come-first-served splitting technique to select a collision resolution interval, and provides two contention mini-slots to improve the likelihood of successful reservations. Each contending user transmits a reservation request in a randomly selected contention mini-slot. Two contention mini-slots are provided for a predetermined maximum number of collision resolution iterations, after which only one contention mini-slot is provided.

Method Of Scheduling Higher And Lower Priority Data Packets

View page
US Patent:
62051504, Mar 20, 2001
Filed:
May 28, 1998
Appl. No.:
9/086394
Inventors:
Chester A. Ruszczyk - Chicago IL
Assignee:
3Com Corporation - Santa Clara CA
International Classification:
H04L 1256
US Classification:
370412
Abstract:
A method for scheduling lower priority and higher priority data packets in a network system is provided. The method allows a network device to schedule the order in which data packets are sent and received on a network system using dual queues. As the network device receives data packets, the network device places data packets into a first queue and sorts the data packets as higher priority and lower priority data packets based upon a transmission deadline of each data packet. Subsequently, the network device places the high priority data packets into a second queue and the lower priority data packets into a third queue. The network device schedules data packets for execution in the second using a first scheduling method while using a second scheduling method to schedule data packets in the third queue. When a transmission deadline for a lower priority data packet expires in the third queue, the network device promotes a data packet from the third queue to the second queue for rescheduling. This method ensures that lower priority data packets are not starved out of delayed in execution by higher priority data packets.

System, Device, And Method For Sharing Contention Mini-Slots Among Multiple Priority Classes

View page
US Patent:
58869930, Mar 23, 1999
Filed:
May 30, 1997
Appl. No.:
8/865924
Inventors:
Chester A. Ruszczyk - Chicago IL
Whay Chiou Lee - Cambridge MA
Imrich Chlamtac - Dallas TX
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H04J 314
US Classification:
370451
Abstract:
A system, device, and method for sharing contention mini-slots among multiple priority classes determines an aggregate feedback state for each of the priority classes, determines a preferred allocation of contention mini-slots for each of the plurality of priority classes using the aggregate feedback state, and determines an actual allocation of contention mini-slots for each of the plurality of priority classes using the preferred allocation. The actual allocation of contention mini-slots is determined by making a preliminary allocation for each of the priority classes based on the preferred allocation and then allocating any remaining contention mini-slots among the priority classes.

Method, Device And Router For Providing A Contention-Based Reservation Mechanism Within A Mini-Slotted Dynamic Entry Polling Slot Supporting Multiple Service Classes

View page
US Patent:
56152124, Mar 25, 1997
Filed:
Sep 11, 1995
Appl. No.:
8/526517
Inventors:
Chester A. Ruszczyk - South Boston MA
Levent Gun - Hopkinton MA
Assignee:
Motorola Inc. - Schaumburg IL
International Classification:
H04J 316
US Classification:
370433
Abstract:
The entry polling (EP) method (900) of the present invention primarily incorporates two types of polling: contention based and standard polling. The present invention provides several advantages over present polling approaches. EP slots allow multi-priority users to compete for access into the standard polling scheme. The reservation channel is efficiently used by dynamically adjusting the frequency of contention slots based on system dynamics and dynamically changing the number of contention minislots for each service category within a contention slot with the case of sending only one minislot per slot. The channel is assigned primarily to active users. Pipeline polling is also incorporated, thus providing full use of the upstream channel. Since the local state information is provided by the user, the central controller may allow multiple variable length packets to be sent.
