A system and method for optimized stream management are provided. The method includes retrieving priority data; determining, in real-time, a current priority tree based on the retrieved priority data, wherein the priority tree includes at least one node representing a stream; identifying, based on the retrieved priority data, at least one relative weight of the at least one node; determining an effective weight based on each identified relative weight; and filling a buffer based on the current priority tree and the at least one effective weight.

A virtual private network (VPN) over a telecommunications network is created by sending a request from a first VPN device to a second VPN device for establishing a VPN between the first and second VPN devices. The request includes a first signed certificate having a verified VPN parameter for the first VPN device. A reply is received at the first VPN device from the second VPN device that includes a second signed certificate having a verified VPN parameter for the second VPN device. The VPN is established between the first and second VPN devices based on each verified VPN parameter for each of the first and second VPN devices.

A system for allocating a different class of service to each network connection in a plurality of network connections, where each network connection corresponds to one or more virtual channels. The system can include a plurality of virtual channels that connect a first computer and a second computer. Each virtual channel can service at least a portion of the network traffic generated using a remote-display protocol. The system can also include a plurality of network connections, where each network connection corresponds to at least one of the virtual channels. Each network connection of the system can have an assigned port number and an assigned class of service that corresponds to a transmission priority level. The class of service assigned to each network connection can be unique from the classes of service assigned to other network connections.

A method for setup of a network device and a system thereof are provided. The method is operated in a gateway device in a LAN. In the method, a software sequence operated in the gateway device receives packets generated by a terminal device in the LAN. After analyzing the packets, a message for triggering a setting process is generated if an event in compliance with a trigger condition is determined from the packets. The message for triggering a setting process is transmitted to a default setup device. The setup device is such as a computer device that allows the user to set up parameters according to an event requirement. When the network device receives the parameters, a corresponding function in the network device is re-activated.

A data communication system determines Software Defined Network (SDN) Quality-of-Service (QoS). SDN applications transfer SDN controller Application Programming Interface (API) calls and receive SDN controller API responses. The SDN applications measure Key Performance Indicators (KPIs) and transfer SDN application KPI data. An SDN controller receives the controller API calls, transfers the controller API responses, transfers SDN data machine API calls, and receives SDN data machine API responses. The SDN controller measures KPIs and transfer SDN controller KPI data. SDN data machines receive the SDN data machine API calls, perform SDN actions on user data responsive to the data machine API calls, and transfer the data machine API responses. The SDN data machines measure KPIs and transfer SDN data machine KPI data. An SDN QoS server processes the SDN KPI data to generate an SDN QoS score.

A distributed sender driven Admission Control System (ACS) is described herein, leveraging Weighted-Fair Quality of Service (QoS) queues, found in standard NICs and switches, to guarantee RPC level latency service level objectives (SLOs) by a judicious selection of QoS weights and traffic-mix across QoS queues. ACS installs cluster-wide RPC latency SLOs by mapping LS RPCs to higher weight QoS queues, and coping with overloads by adaptively apportioning LS RPCs amongst QoS queues based on measured completion times for each queue. When the network demand spikes unexpectedly to predetermined threshold percentage of provisioned capacity, ACS achieves a latency SLO that is significantly lower than the state-of-art congestion control at the 99.9th-p and admits significantly more RPCs meeting SLO target when RPC sizes are not aligned with priorities.

A server includes a plurality of nodes that are connected by a network that includes an on-chip network or an inter-chip network that connects the nodes. The server also includes a controller to configure the network based on relative priorities of workloads that are executing on the nodes. Configuring the network can include allocating buffers to virtual channels supported by the network based on the relative priorities of the workloads associated with the virtual channels, configuring routing tables that route the packets over the network based on the relative priorities of the workloads that generate the packets, or modifying arbitration weights to favor granting access to the virtual channels to packets generated by higher priority workloads.

A controller of a radio access network calculates physical path resource information which is resource information about physical paths between devices in the network, and abstract path resource information which expresses the physical path resource information in a representative manner. When receiving a request to create a slice, the controller determines whether a slice that satisfies a requested condition is creatable based on the abstract path resource information and, when determining that the slice that satisfies the requested condition can be created, creates the slice by selecting a physical path that satisfies the requested condition based on the physical path resource information.

Techniques based on the Theory of Bottleneck Ordering can reveal the bottleneck structure of a network, and the Theory of Flow ordering can take advantage of the revealed bottleneck structure to manage and configure network flows so as to improve the overall network performance. These two techniques provide insights into the inherent topological properties of a network at least in three areas: (1) identification of the regions of influence of each bottleneck; (2) the order in which bottlenecks (and flows traversing them) may converge to their steady state transmission rates in distributed congestion control algorithms; and (3) the design of optimized traffic engineering policies.

Methods, systems, and devices for wireless communications are described. A base station may transmit, to a user equipment (UE), a bandwidth size indication that indicates a respective bandwidth size configured for each operating configuration of a set of operating configurations supported at the UE. The UE may transmit, to the base station, a priority indication for at least one operating configuration of the set of operating configurations based on the bandwidth size indication. The priority indication may correspond to a bandwidth size of the at least one operating criterion satisfying one or more criteria for data traffic. The base station may transmit, to the UE, a configuration indication that indicates to communicate according to a first operating configuration of the set of operating configurations based on the priority indication. The UE may communicate the data traffic with the base station based on the first operating configuration.
