  • Patent number: 10285026
    Abstract: Systems and methods are described herein for enabling sharing of call and/or messaging services between mobile devices via wireless connection, e.g. a Bluetooth connection. The systems and methods allow a first mobile user to register as a host user. A second mobile user (guest user) sends a service sharing request, via the Bluetooth connection, to the host user's mobile device requesting permission to make calls and/or send messages using the host user's mobile account. When the host user accepts the service sharing request, the service sharing system inserts an identification code of the guest user in the call data record to help identify the actual call/message originating party. Once a transaction is established between the guest user's mobile device and the destination number, via the Bluetooth connection to the host user's mobile device, the service sharing system may monitor the transaction duration to ensure that it does not exceed the specified call duration or other limit.

  • Patent number: 10129181
    Abstract: Software-Defined Networking (“SDN”) enables flexible flow control by caching policy rules at OpenFlow switches. Compared with exact-match rule caching, wildcard rule caching can better preserve the flow table space at switches. However, one of the challenges for wildcard rule caching is the dependency between rules, which is generated by caching wildcard rules overlapped in field space with different priorities. Failure to handle the rule dependency may lead to wrong matching decisions for newly arrived flows, or may introduce high storage overhead in flow table memory. A wildcard rule caching system, which may be used for SDN partitions the field space into logical structures called buckets, and caches buckets along with all the associated wildcard rules. Doing so resolves rule dependency while using control network bandwidth efficiently. Further, controller processing load and flow setup latency are reduced.

  • Patent number: 10119826
    Abstract: A method for finding an approximation to the all-pairs shortest travel path between a number of predetermined nodes, comprising clustering nodes of an original road network into a plurality of subgroups so that the number of nodes in each subgroup is no greater than a first predetermined threshold and the maximum distance between any two nodes of a subgroup is no greater than a second predetermined threshold; adding information of intra group shortest paths for all pairs in a same subgroup to a newly created higher level road network; adding information of inter group shortest paths for the plurality of subgroups to the same road network; and searching the same road network for the shortest travel path. In those cases in which the path returned is not exact, the path represents one in the original map, even if not necessarily the best one.

  • Patent number: 10122625
    Abstract: A novel method of handling network traffic for cable service flows in a distributed cable system is presented. Such a cable systems use remote distribution nodes in the fields to handle RF communications with cable modems in a distributed fashion. A packet engine is configured to assign a logical interface to each cable service flow in the cable system. Each logical interface in the packet engine is uniquely identifiable by a compound identifier that includes the identifier of the corresponding service flow and the identifier of the remote distribution node. Upon receiving upstream data packet from a particular cable service flow, the remote distribution node applies a set of tags or labels to the data packet identifying the data packet as being from the particular cable service flow. The remote distribution node then forwards the tagged packet toward the packet engine, where the tags/labels are used to direct the packet toward the corresponding logical interface of the particular cable service flow.

  • Patent number: 10110477
    Abstract: Network services can be dynamically configured on an integrated data path by establishing control paths between data plane entities located on the integrated data path and service entities associated with the network services. In this way, routing for the integrated data path is performed with fewer restrictions than traditional data planes, which are largely limited by the relative locations of pre-configured network nodes in the service network. As a result, the integrated data path may traverse a shorter or more favorable route over the services network, thereby achieving improved service network performance, lower latency periods, less congestion, etc. Further, a service topology on the integrated data path can be dynamically re-configured through the addition, removal, or reordering of data plane entities on the integrated data path.

  • Patent number: 10097579
    Abstract: Embodiments provide system and methods for a DDoS service using a mix of mitigation systems (also called scrubbing centers) and non-mitigation systems. The non-mitigation systems are less expensive and thus can be placed at or near a customer's network resource (e.g., a computer, cluster of computers, or entire network). Under normal conditions, traffic for a customer's resource can go through a mitigation system or a non-mitigation system. When an attack is detected, traffic that would have otherwise gone through a non-mitigation system is re-routed to a mitigation system. Thus, the non-mitigation systems can be used to reduce latency and provide more efficient access to the customer's network resource during normal conditions. Since the non-mitigation servers are not equipped to respond to an attack, the non-mitigation systems are not used during an attack, thereby still providing protection to the customer network resource using the mitigation systems.
