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 method for routing traffic between a source node and a destination node in a network comprises: identifying a first group level at which a source group vector and a destination group vector differ; obtaining one or more first route segments between a first source group and a first destination group at the first group level; computing an end-to-end route between the source node and the destination node based on at least the one or more first route segments; and routing traffic between the source node and the destination node on the end-to-end route.

Abstract: The method includes transmitting request messages to at least one first network node, the request messages each including at least a sampling time-window and a network slice identifier, the sampling time-window defining a duration of time, the network slice identifier identifying a designated network slice within the communication network, receiving packet reports from the at least one first network node, the packet reports including latency information for packets that are processed by the at least one first network node during the sampling time-window for the designated network slice, and controlling the operation of the communication network based on the latency information.

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.
