  • Routing system for internet traffic
    Patent number: 9525638
    Abstract: A deterministic approach for route selection in the Internet and other multi-homed networks is presented that is based upon a mathematical model that takes into consideration performance and costs while satisfying commitment constraints. The approach is expressed with a linear programming formulation that can be solved with conventional linear programming solver software. Performance metrics can be defined and combined in order to achieve the best route selection depending on requirements. Some of the potential benefits of the approach include: a global optimal solution for routing traffic (using metrics such as performance, cost, and other constraints), a dynamic weight assignment for performance metrics, and a flexible problem definition to add routing rules (e.g. static and restricted routes) to the model.

  • Method and system for load balancing in a software-defined networking (SDN) system upon server reconfiguration
    Patent number: 9497123
    Abstract: In one embodiment, a method for load balancing in a software-define networking (SDN) system includes, upon receiving a packet, determining whether a matching entry for the packet in a server distribution table contains both a current and new server selection. If the matching entry contains both, it is determined whether there is a matching entry for the packet in a transient flow table, where the transient flow table maintains server selections when at least one of the plurality of servers is reconfigured. Upon determining that there is no matching entry for the packet in the transient flow table, the method determines whether the packet is a first packet of a traffic flow. If the packet is the first packet of a traffic flow, the packet is forwarded according to the new server selection of the matching entry in the server distribution table, and the transient flow table is updated.

  • Relay device, communication system and relay method
    Patent number: 9497018
    Abstract: A jitter occurring due to a difference in operation timing between a receiving part and a processing part is reduced. The receiving part receives reception data. The processing part processes the reception data and generates transmission data. A transmitting part transmits the transmission data at a timing at which a transmission delay time has passed since a timing at which the processing part generates the transmission data. The transmission delay time is a time obtained by subtracting a process delay time from an overall delay time. The process delay time is a time that passes since a timing at which the receiving part receives the reception data until a timing at which the processing part processes the reception data.

  • Device configuration in a hybrid communication network
    Patent number: 9480014
    Abstract: An access point selector can implement functionality for selecting an access point that should establish a communication link with a client device attempting to join a communication network. The access point selector can receive notifications from access points, in response to the client device's button being activated. Information in the received notifications can be analyzed and one of the access points (that transmitted the notifications) can be selected to establish the communication link with the client device. In some embodiments, prior to selecting an access point that should establish the communication link with the client device, the access point selector can attempt to identify a designated access point (DAP) in the communication network. The access point selector may execute operations for selecting the access point only if the DAP cannot be identified in the communication network.

  • Capacity sharing between wireless systems
    Patent number: 9479940
    Abstract: Systems and methods presented herein provide for capacity sharing between wireless systems. In one embodiment, a scheduler is operable with a plurality of wireless base stations. Each base station is operable to digitize a frequency spectrum of radio communications from a plurality of user equipment (UEs). The scheduler communicatively couples to first and second Mobile Central Offices (MCOs). The scheduler processes the digitized frequency spectrums of the base stations, extracts radio communications of a first of the UEs from the digitized frequency spectrums of one or more of the base stations coupled to the first MCO, determines that a capacity of the first MCO has been exceeded, determines that a capacity of the second MCO is available, acquires at least a portion of the capacity of the second MCO, and handles a call of the first UE through the capacity acquired from the second MCO.
