    Abstract: Computer-implemented methods and a system are provided for distributing tasks between a plurality of processes in a computer network. A method includes distributing, by a load balancer in the computer network, tasks between the plurality of processes. The method further includes maintaining, by the load balancer, a registry for each of the tasks. For a given task, the registry indicates which of the plurality of processes to which the given task is distributed based on a hash function. The method also includes forming, by the load balancer, a respective set of registries for each of the plurality of processes, based on a set of thresholds. The method additionally includes redefining, by the load balancer, the set of thresholds when one of the plurality of processes ceases or a new process, added to the plurality of processes, commences.

    Abstract: A load balancing device and method are provided. The load balancing device includes a processor. The processor is configured to receive a plurality of tasks from a plurality of user devices, each of the plurality of tasks involving a respective one of multiple sets of sessions. The processor is further configured to generate a task ID for each of the plurality tasks using a randomization function, at least one task ID for at least one of the plurality of tasks changing over time responsive to one or more criterion. The processor is additionally configured to allocate the plurality of tasks amongst a set of worker entities such that all the sessions involved in the plurality of tasks received from a respective same one of the plurality of user devices is assigned to a same one of the worker entities in the set.

    Abstract: Advertisements are shown to users when the queue underflows to avoid video stalls in players/plugins so users see minimum disruption in video quality. The advertisements are pre-fetched and cached at the mobile phone to schedule them during queue underflows. If there is no congestion in the network, the queue does no underflow and advertisements are shown only to meet ad contracts. During network congestion or disruption, the queue might underflow and specific advertisements are shown to equalize network unavailability until sufficient video data has been received.

    Abstract translation: 当队列下溢时，向用户显示广告，以避免播放器/插件中的视频停滞，因此用户看到视频质量最小化。 在移动电话上预先抓取和缓存广告，以便在队列下溢期间进行安排。 如果网络中没有拥塞，则队列不会下溢，并且仅显示广告以满足广告合同。 在网络拥塞或中断期间，队列可能会下溢，并显示特定广告，以均衡网络不可用性，直到收到足够的视频数据。
