摘要： An Adaptive Bitrate (ABR) Quality of Experience (QoE) Management Unit manages bandwidth usage and QoE at a customer premises where multiple client devices independently download content from multiple providers. An overall virtual pipe to the premises includes a Hypertext Transfer Protocol (HTTP) inner pipe, a non-HTTP inner pipe, an ABR inner pipe, and a non-ABR inner pipe. The Unit determines a data cap for a current billing cycle; and determines, based on policy management settings and the data cap for the current billing cycle, at least one of: a bandwidth cap for the overall virtual pipe, a bandwidth cap for the HTTP inner pipe, a bandwidth cap for the non-HTTP inner pipe, a bandwidth cap for the ABR inner pipe, and a bandwidth cap for the non-ABR inner pipe. Responsive to the determination of the bandwidth caps, the Unit throttles traffic within at least one of the inner pipes.

摘要： A method may include determining a capacity metric for sectors in a network, estimating a usage metric for each of the sectors for periods of time and determining a number of user devices that can access data services based on the capacity metric and the usage metric. The method may also include storing information identifying the determined number of user devices, receiving a request from a first user device for access to data services during a first period of time and accessing the stored information to determine whether the number of user devices that can access data services for the first period of time is greater than zero. The method may further include providing access via the wireless network to the first user device during the first period of time, in response to determining that the number of user devices that can access data services is greater than zero.

摘要： A network element in a data center includes a plurality of servers and a switch. The switch includes a plurality of physical ports, a packet-forwarding table, and an application program interface (API) for modifying a packet-forwarding behavior of the switch. The packet-forwarding table determines a packet-traffic distribution across the servers by mapping packet traffic arriving at the switch to the plurality of ports. Each port of the plurality of physical ports is in communication with one of the servers. The network element further includes means for determining in real time the packet-traffic distribution across the servers, and means for dynamically changing the packet-traffic distribution across the servers in response to the determined packet-traffic distribution by modifying the packet-forwarding behavior of the switch through the API of the switch.

摘要： A data transmitting device configured to transmit data to a data receiving device via a communication line, the data transmitting device determines, based on first bandwidth information indicating a first bandwidth of the communication line from the data transmitting device to the data receiving device and first load information indicating a first load of the data receiving device, whether a first process is to be executed on first data before the first data is transmitted to the data receiving device, when it is determined that the first process is to be executed, executes the first process on the first data, and transmits, to the data receiving device, the first data on which the first process is executed, and when it is not determined that the first process is to be executed, transmits the first data to the data receiving device without executing the first process.

摘要： For a managed network including first and second managed switching elements that implement logical data path sets, some embodiments provide a method that establishes, from the first managed switching element, a network tunnel through a network to the second managed switching element. The network includes a set of unmanaged switching elements. Through the network tunnel, the network forwards logical network data to the set of unmanaged switching elements for the set of unmanaged switching elements to forward to the second managed switching element. The logical network is hidden from the set of unmanaged switching elements when the logical network data is forwarded through the tunnel.

摘要： In one embodiment, a service enabled network (SEN) controller receives, from a control plane of a network service device, service instructions for corresponding network services. The SEN controller may then distribute the service instructions for the network services to appropriate network access devices within the computer network, such that each of the network access devices may correspondingly implement the network services at their respective data planes, thus providing a distributed implementation of the network service within the computer network.

摘要： A system for determining a worst case latency for a specific information flow that is part of a plurality of information flows and a worst case backlog for a specific queue that is part of a plurality of queues is disclosed. The plurality of information flows and plurality of queues are part of a configuration. The system performs operations including determining a maximum busy period length for the configuration. The operations include determining a set of candidate starting times for the configuration based on the maximum busy period length. The operations further include determining a maximum layout for a plurality of information flows within the configuration. The operations include updating the worst case latency and the worst case backlog based on the maximum layout. Finally, the operations include determining the worst case latency for the specific information flow and the worst case backlog for a specific queue.
