Abstract: A network node configured to transmit packets to a destination node in a packet network, includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the network node to: assemble at least a first packet including a plurality of data units, each of the plurality of data units being grouped into one of a connection group, a network function group or an application group; and transmit the first packet to the destination node.

Abstract: Various embodiments relate to a path computation element (PCE) configured to control a network having ingress edge nodes, interior nodes, and egress edge nodes, including: a network interface configured to communicate with the network; a memory; and a processor coupled to the memory and the network interface, wherein the processor is further configured to: receive a request for a first continuous guaranteed latency (CGL) flow to be carried by the network; make routing and admission control decisions for the requested first CGL flow without provisioning of the first CGL flow and the configuration of schedulers in the interior nodes of the network; and provide flow shaping parameters to a flow shaper at an ingress edge node of the first CGL flow.

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: A scheduling controller configured to control a network having ingress nodes, interior nodes, and egress nodes, including: a network interface configured to communicate with the network; a memory; and a processor coupled to the memory and the network interface, wherein the processor is further configured to: define a traffic shaping hierarchy with a first level having a first traffic shaper associated with an ingress link between an ingress node and an interior node and a second level with a plurality of second traffic shapers associated with each path of a plurality of paths between the ingress link and the egress nodes; determine, each time a service assignment is due, which of the plurality of paths associated with the ingress link to service, based upon which of the plurality of paths has a lowest eligible finishing potential and wherein each link in the path has an eligible finishing potential; and determine, for the determined path, which of the packet queues associated with the network flows that are routed through the path to service, based upon which of the plurality of queues has a lowest eligible finishing potential.

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.

Abstract: Various example embodiments for supporting guaranteed-latency networking are presented herein. Various example embodiments for supporting guaranteed-latency networking may be configured to support guaranteed-latency networking based on use of a time division multiplexing (TDM) frame, such as a periodic service sequence (PSS), to support transmission of packets of a set of flows. Various example embodiments for supporting guaranteed-latency networking based on use of a PSS may be configured to support guaranteed-latency networking based on use of various PSS computation enhancements. Various example embodiments for supporting guaranteed-latency networking based on use of a PSS may be configured to support guaranteed-latency networking based on use of flow bundling.
