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: Systems and methods for adaptive video delivery over a network, including receiving a plurality of types of data flows from one or more network base stations; separating resource management of the plurality of types of data flows, wherein the data flows include one or more of adaptive video streaming flows, regular video traffic flows, and other traffic flows by resource slicing. A scheduling framework for adaptive video delivery is instantiated; available choices of video bit rates for all users is received as input to an allocator; optimal allocation of resources is computed for all users by determining and selecting an optimal bit rate for each user using the allocator; the optimal bit rate being sent to an enforcer; resources across flows are isolated using the enforcer; and the optimal bit rate for each user is enforced using per-flow traffic shapers to maximize resource utilization without reaching network capacity.

Abstract: Systems and methods for managing network resources, including managing a generated virtualized data plane network using a central controller. Virtual machine (VM) resources are assigned to two or more different network functions at a local data center. Traffic is dynamically optimized based on at least one of aggregate traffic demands and quality of service (QoS) goals, and resource allocations and inter-data center (DC) bandwidth resources are determined for VMs for a plurality of services. VMs for each middlebox function and a routing plane for each service are configured based on the determined resource allocation, and flows are routed based on the resource allocation and one or more configured network paths using an overlay-routing framework.
