Aspects herein provides a system that utilizes a virtualization layer at a distribution unit or central unit in a network. The virtualization layer includes a plurality of virtual resource blocks that are pooled together as a resource for both a public portion of the network and one or more private portions of the network. Based on loading monitoring of the different portions of the network, the plurality of virtual resource blocks in the pool can be dynamically reallocated between the public and private networks to accommodate and optimize loading. The plurality of virtual resource blocks are mapped to physical resource blocks for scheduling and utilization based on the reallocation.

A congestion control processing method uses a two-level scheduling manner of a forwarding device and a destination device, where the network device of a data center network performs coarse-grained bandwidth allocation based on weights of flows destined for different destination devices. The network device allocates each flow a bandwidth that does not cause congestion, and notifies the destination device. The destination device performs fine-grained division, determines a maximum sending rate for each flow, and notifies a packet sending device of the maximum sending rate.

Core network slices that belong to a given operator community are efficiently tracked at the network control/user plane functions level, with rich data analytics in real-time based on their geographic instantiations. In one aspect, an enhanced vendor agnostic orchestration mechanism is utilized to connect a unified management layer with an integrated slice-components data analytics engine (SDAE), a slice performance engine (SPE), and a network slice selection function (NSSF) in a closed-loop feedback system with the serving network functions of one or more core network slices. The tight-knit orchestration mechanism provides economies of scale to mobile carriers in optimal deployment and utilization of their critical core network resources while serving their customers with superior quality.

A playout delay adjustment method includes: adjusting a playout delay surplus based on a difference value between a first playout delay obtained in a first scheme and a second playout delay obtained in a second scheme and determining an adaptation type of a current frame according to whether a previous frame is an active frame; and when the determined adaptation type is signal-based adaptation, performing time scale modification (TSM) according to an adaptation scheme determined according to a comparison result between the first playout delay and the second playout delay and a comparison result between a target delay and the first playout delay.

Methods and systems for Link Binding Management (LBM), including architectural design, detailed procedures, and embodiments to related standards, are described herein. In a first embodiment, an LBM Architecture A is disclosed which includes four logical entities: a Resource Creator (RC), a Source Resource Host (SRH), a Destination Resource Host (DRH), and a Link Binding Coordinator (LBC). Interactions are defined for these four entities to cooperate in order to efficiently manage link bindings (e.g. link binding creation, link binding update, etc) between source and destination resources. In a second embodiment, an LBM Architecture B is also disclosed which includes a Resource Repository (RR), a SRH.sub.2, a DRH, and a LBC. Interactions on those actors are developed towards efficient link binding management. Detailed procedures for LBM Architecture B are also disclosed.

An example method for lockless communications network resource quota sharing occurs at a first charging node of a distributed charging system comprising multiple charging nodes. The example method comprises: receiving, from a requesting entity, a first communications network resource quota request for requesting a first resource amount from the shared resources plan; without confirming that the shared resources plan has enough available resources to allot the first resource amount, providing, to the requesting entity, a first communications network resource quota for the first member, wherein the first communications network resource quota indicates a second resource amount less than the first resource amount and/or wherein the first communications network resource quota is associated with a validity time indicating when the first communications network resource quota expires; and sending, to a second charging node, a first resource reservation request for reserving resources of the shared resources plan.

Disclosed herein are system, method, and computer program product embodiments for deploying a configurable throttling library in a cloud platform that throttles requests according to fully customizable parameters across each origin and resource. An administrator can harness the full customization provided by the throttling library to specify increment, decrement, delay, threshold, expiration, and rejection policies. These policies allow administrators to specify parameters guiding throttling on a per-user and a per-resource basis, thus providing significantly enhanced configuration capabilities to the administrator to tailor the throttling to the unique requirements of their applications and the usage thereof.

A method performed by a controlling computer node in a network with a plurality of subordinate computing nodes, the method including: receiving, from a first subordinate computer node, information indicating computing resource impacts for a plurality of different processing functions; receiving, from a communication endpoint, a processing task; determining an impact upon available resources of the first subordinate computer node if the task were to be assigned to the first subordinate computer node, wherein the determining is performed using the information indicating computing resource impacts; and assigning the task to either the first subordinate computer node or another one of the subordinate computer nodes based at least in part on the determining the impact.

A communication method for a transmission-side node and a reception-side node performing transmission and reception via a communication line in a predetermined cycle includes: causing the transmission-side node and the reception-side node to transmit identification information indicating a status of an event of transmission of object data to the communication line in the predetermined cycle; if a new event of transmission of the object data occurs, causing the transmission-side node to update a value of the identification information and transmit the updated identification information together with the object data to the communication line in the predetermined cycle; and causing the reception-side node to receive the object data and the updated identification information, and upon completion of reception of the object data corresponding to the updated identification information, update a value of the identification information and transmit the updated identification information to the communication line in the predetermined cycle.
