Abstract: Various example embodiments for supporting scalable deterministic services in packet networks are presented. Various example embodiments for supporting scalable deterministic services in packet networks may be configured to support delay guarantees (e.g., finite end-to-end delay bounds) for a class of traffic flows referred to as guaranteed-delay (GD) traffic flows. Various example embodiments for supporting scalable deterministic services in packet networks may be configured to support delay guarantees for GD traffic flows of a network based on a queuing arrangement that is based on network outputs of the network, a packet scheduling method that is configured to support scheduling of packets of the GD traffic flows, and a service rate allocation rule configured to support delay guarantees for the GD traffic flows.

Abstract: Systems, methods, apparatuses, and computer program products for packet latency reduction in mobile radio access networks. One method may include, when a buffer of a first sublayer of a wireless access link is empty and there is a new data unit in the first sublayer or when the first sublayer buffer is not empty and a data unit leaves a second sublayer buffer, comparing the number of data units currently stored in the second sublayer buffer with a queue length threshold that defines a total amount of space in the second sublayer buffer. When the number of data units currently stored in the second sublayer buffer is less than the queue length threshold, the method may also include transferring the data unit from the first sublayer to the second sublayer.

Abstract: Various example embodiments for supporting congestion control in a communication network are presented. Various example embodiments for supporting congestion control in a communication network may be configured to support protocol agnostic cognitive congestion control in the communication network. Various example embodiments for supporting protocol agnostic cognitive congestion control in a communication network may be configured to support protocol agnostic cognitive congestion control in the communication network by enabling a sending node of a path over which a set of flows is to be communicated to determine the minimum target transmission rate among the links along the path over which the flows are to be communicated and to use the minimum target transmission rate among the links along the path over which flows are to be communicated in order to control transmission of packets over the path at Layer 3 of the Open Systems Interconnection (OSI) model.

Abstract: An application specific interface (AA-NAPI) associated with an application for the purpose of controlling the networking aspects of the application session is provided by communication service provider (CSP). Cost model of network service types associated with a specific application type is learned by using the AA-NAPI. For each service-point joining the session, network properties are queried by using the AA-NAPI. During continuous service quality monitoring, upon detection of quality degradation leading to the decision to upgrade session quality, network service-type associated with a specific server-point is changed by using the AA-NAPI. Network specific actions are taken to reconfigure the network so that the requested service type is received by the specific service-point. New network capability is activated to improve network service level by using the AA-NAPI. Network specific actions are taken by the network to install new network capabilities so that the specific service-point's service quality is improved as requested.
