  • Patent number: 9014191
    Abstract: Systems and techniques for forwarding a data packet between network components in a virtualized network system are presented. Virtual machines in each virtual network in the virtualized network system are mapped to a unique routing table. Internet protocol (IP) addresses of virtual machines in a virtual network can overlap with IP addresses of virtual machines in another virtual network. A data packet is associated with a particular virtual network based on a tag stored in the data packet. As such, the data packet is forwarded based on a particular routing table associated with the particular virtual network. Additionally, routing domain information can be encoded into an outer source IP field of the data packet at the beginning of an IP tunnel. Furthermore, the routing domain information in the outer source IP field can be used to forward the data packet at the end of the IP tunnel.

  • Patent number: 9014282
    Abstract: An accurate non-Data Over Cable Service Interface Specification (non-DOCSIS) clock signal is generated at the downstream output of a DOCSIS network. In one example method, a downstream DOCSIS Timing Protocol (DTP) client in the DOCSIS network is frequency synchronized to an upstream DTP server in the DOCSIS network. DOCSIS timing information, along with one or more timing correction factors received at the DTP client, is used to time synchronize the DTP client to the DTP server. Based on the time and frequency synchronization between the DTP server and the DTP client, the clock signal is generated at the output of the DTP client in accordance with the non-DOCSIS timing protocol.

  • Patent number: 8995449
    Abstract: A packet processor provides for rule matching of packets in a network architecture. The packet processor includes a lookup cluster complex having a number of lookup engines and respective on-chip memory units. The on-chip memory stores rules for matching against packet data. Each of the lookup engines receives a key request associated with a packet and determines a subset of the rules to match against the packet data. As a result of the rule matching, the lookup engine returns a response message indicating whether a match is found.

  • Patent number: 8989070
    Abstract: With the proliferation of Machine-Type Communication (MTC), an excessive use of device trigger messages in a Long Term Evolution (LTE) network can have negative effects on user equipment (UE). These effect can include a shortening of UE battery life and/or excessive signalling caused by the frequent changing from an idle mode to an active mode. An MTC Interworking Function (MTC-IWF) can be configured to determine the status of a UE to which a device trigger message is intended. If the device trigger message is low priority and the UE is in an idle state, the MTC-IWF or Mobile Management Entity (MME)/Serving GPRS Support Node (SGSN)/Mobile Switching Center (MSC) can buffer the device trigger message.

  • Patent number: 8982876
    Abstract: A Voice-over-Internet protocol (VOIP) communications network system that enables direct-dialed (single-stage) access to the Internet Protocol network from the circuit-switched network. Specifically, the VOIP network system includes a VOIP service implemented on a communications system which, after a customer number has been registered for the service, automatically recognizes calls from the registered customer's telephone number and determines if the call can be routed as a VOIP call over the IP network. In embodiments of the present invention, the customer can register for the VOIP service by selecting both a provider and a calling plan or by only selecting a provider. The system can be implemented to handle intra-state, inter-state and international voice-band calls (for example, regular telephone calls, facsimile transmissions and modem initiated calls) using standard circuit-switched telephone lines, cable, twisted pair, digital subscriber line and wireless.

  • Patent number: 8982887
    Abstract: A computer system, method and program for routing. A router receives a message packet, and in response, the router reads a payload in the message packet to identify an application that sent the message packet or a user of the application that sent the message packet, as identified from the reading of the payload. The router determines a routing path for the message packet based at least in part on the identity of the application that sent the message packet or the user of the application that sent the message packet. The router forwards the message packet to a next hop in the routing path which was determined.

  • Patent number: 8976792
    Abstract: Techniques for providing an extended layer 2 network. Embodiments receive, at a first network device in a first layer 2 network within the extended layer 2 network, a data packet specifying a destination Media Access Control (MAC) address. Upon determining that the destination MAC address is a site virtual MAC (S-VMAC) address, the data packet is forwarded to a second network device in a second layer 2 network within the extended layer 2 network and associated with the S-VMAC address, where the second network device is configured to determine a second destination MAC address for the data packet based on an Internet Protocol (IP) address specified in the data packet, and is further configured to forward the data packet to a destination device associated with the determined second destination MAC address.

  • Patent number: 8976721
    Abstract: A clock generator generates a first clock. A receiver transitions, based on the first clock, from a power save mode to an active mode to receive a DTIM beacon from an access point. The DTIM beacon is transmitted at a DTIM beacon interval based on a second clock of the access point. A beacon sensing module determines a number of times the DTIM beacon is missed by the receiver during a predetermined time period subsequent to the receiver transitioning from the power save mode to the active mode. A transmit module transmits a number of requests to the access point during a given DTIM beacon interval. The number of requests is based on the number of times the DTIM beacon is missed. A synchronization module receives information about the second clock from the access point and synchronizes the first clock to the second clock based on the information.

  • Patent number: 8964703
    Abstract: A system and method for facilitating resource management in OFDM systems is provided. The system permits different and flexible resource cell metric operations levels (e.g. uplink load management, admission control, congestion control, signal handoff control) for different sub-bands. For the uplink load management, there are multiple distinct load operation points (e.g. IoT, RoT) per sub-band group instead of the same operation level across the entire available band. The sub-band groups encompass the entire band. The facilitation system also comprises a variety of transmitting protocols, command increment variable stepsize methods and robust command response methods. The system thus provides more flexible reverse link resource management and more efficient utilization of the bandwidth.

  • Patent number: 8964546
    Abstract: Systems and methods are disclosed herein for measuring the traffic flow on a link. The system includes a processor that is configured to generate aggregate egress data for multiple origin endpoints by aggregating amounts of egress traffic detected by servers processing the egress traffic at the origin endpoints. The processor is also configured to obtain the proportions of traffic flows that traverse each path between each endpoint pair, which includes an origin endpoint and a destination endpoint. Each path includes multiple network links such that a single network link may be shared across multiple paths. Finally, the processor computes an amount of traffic flow on a shared link based on the aggregate egress data and the obtained proportions.
