Patent number: 7653932Abstract: 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-3 CMTS can be used instead of a layer-2 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.Type: GrantFiled: August 30, 2004Date of Patent: January 26, 2010Assignee: Arris GroupInventors: Erich C Arnold, Thomas J Cloonan, Jeffrey J Howe

Patent number: 7653740Abstract: In a metropolitan area network, a method and system for maintaining an accurate total of the amount of allocated bandwidth on the network. A plurality of incoming packets are assigned to a respective plurality of queues of a metropolitan area network switch. Using a fair arbitration scheme, the respective queues are configured to empty at a specified output rate. A finish time for each respective queue is computed, the finish time describing a time at which the respective queue will be emptied using the output rate. The plurality of queues are grouped into multiple groups in accordance with their respective finish times. The earliest group includes the reserved rates of those queues having a finish time indicating an empty condition at a first time increment. The second earliest group includes the reserved rates of those queues having a finish time indicating an empty condition at a second time increment later than the first time increment, and so on.Type: GrantFiled: July 14, 2005Date of Patent: January 26, 2010Assignee: Arris GroupInventors: Adisak Mekkittikul, Nader Vijeh, William J.

Patent number: 7614323Abstract: This invention relates to a corkscrew (1), of the first-class lever type, designed so that once the screw (3) is driven into a cork (10) that is fully inserted into the neck of a bottle (12) and that free end (8) of short fulcrum (5) is placed on the bottle lip (11), a single hand (14) can hold the bottle neck (12) and the free end (2?) of the lever (2) simultaneously. A squeeze of one hand (14) will bring the free end (2?) of lever (2) against the bottle neck (12). The cork (10) is now raised an initial distance from its original position. The operation is repeated using long fulcrum (6) whose free end (9) is placed against the bottle lip (11). In this second position the free end (2?) of lever (2) and the bottle neck (12) are again within range of being grasped with one hand (14). A second squeeze of the hand (14) now moves the cork (10) the rest of the way out of the bottle neck (12).Type: GrantFiled: November 18, 2002Date of Patent: November 10, 2009Inventor: Brent J. Warner

Patent number: 7512698Abstract: A method and apparatus for dynamic quality adjustment of digital media based on changing streaming constraints is provided. A digital media server sends a digital media stream according to a set of streaming constraints to a requesting client. Audio and visual information may be sent to a requesting client together in a single stream, or separately in multiple streams. A client sends a request over a control network to the digital media server indicating information of a particular type is no longer desired. In response to receiving the signal, the video server ceases transmission of that particular type of information to the signaling client, thus relaxing streaming constraints.Type: GrantFiled: September 1, 2000Date of Patent: March 31, 2009Assignee: Broadband Royalty CorporationInventor: David J.

Patent number: 7474150Abstract: In a broadband communication system there are multi-stage power amplifier systems for amplifying the power of radio-frequency (RF) communication signals. Each stage of the amplifier system results in composite triple beat (CTB) distortion, and if the phase of the CTB distortions are approximately the same (i.e. are in-phase), then the amplitudes of the distortions are added (i.e. “20 dB” rule). The amplifier system of the invention includes one or more phase filters positioned in series between the power amplifier stages. The phase filters are adapted to shift the phase of the communication signals, so that the phase of CTB distortions, resulting from the amplification of the communication signals in the amplifier stages between the phase filters, are substantially different (i.e. are out-of-phase). Thus, only the power of the CTB distortions are added (i.e. “10 dB” rule).Type: GrantFiled: May 19, 2004Date of Patent: January 6, 2009Assignee: Broadband Royalty CorporationInventors: Marcel F. Schemmann, Zoran Maricevic

Patent number: 7239607Abstract: An asynchronous metropolitan packet transport ring having guaranteed QoS. Asynchronous packetized data flow in one direction through a fiber optic loop. A number of Metropolitan Packet Switches (MPS) are coupled to the fiber optic loop. An MPS allows packetized data from an upstream MPS to flow to a downstream MPS over a segment of the fiber optic loop. The MPS also puts packetized data onto and pulls packetized data off of the fiber optic loop. Thereby, flows can access the fiber optic loop via the MPS's. The MPS's also regulate the data rates on a per-flow basis according to setup information supplied by a Ring Management System (RMS). If one segment of the fiber loop becomes overly congested, the MPS guarantees quality of service for those flows by deallocating available bandwidth from flows upstream to the point of congestion. Utilization of packet transport ring capacity is optimized by allocating any bandwidth that becomes available to active flows according to a pre-specified weighting scheme.Type: GrantFiled: June 30, 2000Date of Patent: July 3, 2007Assignee: Broadband Royalty Corp.Inventors: Nader Vijeh, Adisak Mekkittikul
