20090262644 | INTELLIGENT TRAFFIC OPTIMIZER - Bandwidth is assigned to subscribers of a data network by applying logic of one or more network devices to sample bits of information communicated over a network communication medium to identify if there is a network congestion condition or an extremely lightly loaded condition. The maximum bandwidth assigned to a subscriber is below a normative maximum bandwidth assigned to the subscriber if the network is congested and the logic of the one or more network devices identifies the subscriber as a heavy bandwidth user. The maximum bandwidth assigned to a subscriber is above the normative maximum bandwidth if the network is extremely lightly loaded and the subscriber is a heavy bandwidth user. | 10-22-2009 |
20090274156 | CARRIER ETHERNET OVER DOCSIS - A network includes a provider edge device with logic to encapsulate Ethernet frames received from customer equipment into Data Over Cable Service Interface Specification (DOCSIS) frames using Layer Two Tunneling Protocol. The provider edge device further includes logic to implement a virtual switch instance (VSI). | 11-05-2009 |
20090285233 | MULTI-SERVICE PHY BOX - A data communication system includes multiple Media Access Control (MAC) units, multiple physical layer (PHY) interface units, and logic to communicate between the MAC units and the PHY units using a single tunneling protocol over Internet Protocol (IP). | 11-19-2009 |
20100005500 | METHOD FOR SIMULTANEOUSLY MANAGING HIGH-SPEED DATA AND VIDEO STREAMS IN A SINGLE MAC PROCESSING ENVIRONMENT - A packet data flow processor applies a first level of Data Over Cable Service Interface Specification (DOCSIS) processing to packet flows that are not from trusted sources, and applies a second level of DOCSIS processing, simpler than the first level, to packet flows from the trusted sources. | 01-07-2010 |
20100183021 | Method and Apparatus for Queuing Data Flows - 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. | 07-22-2010 |
20110161510 | Method and system for layer-3 subscriber login in a cable data network - 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. | 06-30-2011 |
20150286543 | Sparing Method and Apparatus - A device and method for routing separate data flows to subscribers on a content distribution network are provided. The device includes a group of access modules having signal processing circuitry each coupled to a corresponding interface unit. The interface units are coupled in a daisy chain configuration. The access modules include at least first and second active access modules and a spare access module. The group being configured for normal mode operation in which the first active access module processes a first data flow and the second active access module processes a second data flow, and the group being configured for sparing event mode operation in which the first data flow is automatically switched to the second active access module and the second data flow is automatically switched to the spare access module. | 10-08-2015 |
20160080074 | Intra-Chassis Protection Systems and Methods for Passive Optical Network Optical Line Terminals - An optical line terminal is operable in a passive optical network. The optical line terminal includes a chassis. A plurality of optical subsystems are disposed within the chassis. Each optical subsystem is operable to generate optical signals for delivery to a port. Each optical subsystem includes one or more optical switches. When a fault condition is detected at a first optical subsystem preventing the delivery of first optical signals generated by the first optical subsystem to the port of the first optical subsystem, the optical switches switch to deliver second downstream optical signals generated by a second optical subsystem to the port of the first optical subsystem. | 03-17-2016 |
