  • Patent number: 8837282
    Abstract: In one embodiment, a method includes obtaining a message associated with a data flow that includes a first indicator that identifies an amount of requested pool bandwidth and a second indicator that identifies a pool with which the data flow is associated. The pool is associated with a plurality of data flows that includes the data flow. The method also includes determining whether the pool has an overall bandwidth allocation, and, if so, determining whether reserving the amount of requested bandwidth would cause the overall bandwidth allocation to exceed a maximum pool bandwidth allocation. Finally, the method includes reserving approximately the amount of requested bandwidth when it is determined that reserving the amount of requested bandwidth would not cause the overall bandwidth allocation to exceed the maximum pool bandwidth allocation. Reserving approximately the amount of requested bandwidth includes increasing the overall bandwidth allocation by the amount of requested bandwidth.

  • Patent number: 8830830
    Abstract: In a network environment, a node may measure and/or recognize network activity or congestion and send feedback to downstream nodes (i.e., higher rank nodes) in response. During periods of lower network activity, lower congestion and/or lower network load, the feedback may direct an upstream flow of packets to be transmitted at a quality of service (QoS) level that allows consumption of more bandwidth than is indicated by a QoS level associated with a service level agreement (SLA) of the upstream flow of packets. During periods of higher network activity, congestion and/or network load, the feedback may limit the upstream flow of packets to the QoS level associated with the SLA of the upstream flow of packets. Accordingly, an upstream node (e.g., a root node) may use feedback to regulate bandwidth used by one or more downstream nodes and/or flows of packets, in part using network activity, congestion and/or bandwidth availability.

  • Patent number: 8817618
    Abstract: Systems and methods for providing trigger based dynamic changes to a packet flow in a communication network are described. The trigger based dynamic changes can include upgrading and downgrading quality of service (QoS), processing the packet flow, and providing services to the packet flow. These changes can be provided by inspecting packets at a gateway for trigger conditions and setting up a proxy instance for the packet flows. The proxy can coordinate QoS changes and management of packet flows. The triggers can be based on the destination of the packet, for example, the uniform resource locator (URL) and/or by the services (e.g., email, video, messaging) that the subscriber is accessing. The triggers can also be based on the identity of the user or agreements a provider might have with an operator of network equipment for users accessing the provider's website.

When the RNC senses an event which indicates that the quality of the RL has substantially deteriorated, the RNC reduces the value of the current data bit rate. Then, in a recovery process, if a similar event does not occur during an established waiting period, the RNC restores the current data bit rate back to the maximum data bit rate.

  • Patent number: 8780920
    Abstract: In a method for establishing a bidirectional data transmission path in a wireless meshed packet-switched communication network, a logical topology in the form of at least one routing tree can be proactively established, wherein a root network node of the routing tree sends first unidirectional data transmission paths regarding routing request messages specifying the root network node to the network nodes of the communication network in periodic time intervals. A first flag is provided in the network nodes of the routing tree that can be put into two different states. Upon receipt of a routing request message, a network node only sends a second unidirectional data transfer path regarding the routing response message specifying the network node to the root-network node if the first flag is switched into a first selectable state. Thus, a bidirectional data transfer path between the root network node and the network node is established.

  • Patent number: 8761693
    Abstract: A traffic amount calculation portion calculates a traffic amount caused by transmission signals received by a transmission signal reception portion. An average traffic amount calculation portion calculates an average traffic amount that is an average of the traffic amount in a nearest predetermined interval. Further, a modulation method setting portion changes a modulation method used by a modulation portion based on the calculated average traffic amount. In addition, a transmission portion transmits transmission signals by using a transmission power amount corresponding to the modulation method used by the modulation portion.

  • Patent number: 8761036
    Abstract: A control application of some embodiments allows a user to enable a logical switching element for Quality of Service (QoS). QoS in some embodiments is a technique to apply to a particular logical port of a logical switching element such that the switching element can guarantee a certain level of performance to network data that a machine sends through the particular logical port. The control application of some embodiments receives user inputs that specify a particular logical switch to enable for QoS. The control application may additionally receive performance constraints data. The control application in some embodiments formats the user inputs into logical control plane data. The control application in some embodiments then converts the logical control plane data into logical forwarding data that specify QoS functions.

  • Patent number: 8755280
    Abstract: An improved method is described for providing Differentiated Services (Diffserv) traffic to a node in a network that implements a security method that discards duplicate packets received at the node. The method includes the step of identifying at least two service levels to be provided to received traffic and assigning different size look-back window counts to each of the service levels. The look-back window count indicates a number of packets that have been previously received at the node that should be compared against a received packet to determine whether a duplicate packet has been received. In one embodiment, a service level that has higher priority is assigned a lower look-back window count and thus examines fewer previously received packets than a service level having a lower priority. Such an arrangement reduces the possibility that traffic having higher priority is dropped as a security measure.

  • Patent number: 8750110
    Abstract: A hybrid network device can implement functionality for automatic path selection and modification in a hybrid communication network. The hybrid network device can select an initial network interface from a plurality of network interfaces for transmitting a packet stream. In response to determining that the medium utilization of the initial network interface exceeds the medium utilization threshold, the hybrid network device can identify one or more packet streams originating from the initial network interface to shift to corresponding one or more alternate network interfaces. The hybrid network device can attempt to reduce the medium utilization of the initial network interface below the medium utilization threshold while maintaining the medium utilization of the one or more alternate network interfaces below the corresponding medium utilization thresholds.

  • Patent number: 8750246
    Abstract: The Quality of Service (QoS) level/service level within a wired network associated with a wireless Local Area Network (LAN) is controlled by assigning to each incoming information frame a Virtual Local Area Network (VLAN) number in accordance with the QoS level/service level determined for that frame. The frame is then routed in the network in accordance with the VLAN number to assure that the path(s) carrying the frame have the requisite characteristics, such as bandwidth, to satisfy the determined QoS level/service level.

  • Patent number: 8737232
    Abstract: The present invention is a system and method for failing over from a current network access medium to an alternative network access medium. A customer premises equipment (CPE) box has ports for connections to a network through several network access media, such as high speed cable connections, DSL connections and dial-up connections. QoS parameters for each of the connections are monitored from a bandwidth manager remote from the CPE box. When it is determined that a fail-over would be beneficial, a message is sent from the bandwidth manager to the CPE box containing a command to fail-over and an identity of the alternate network access media.
