Abstract

A control device for a software programmable network including one or more nodes and supporting traffic of guaranteed quality of service, QoS, and best-effort, BE, traffic with a predetermined resource distribution between guaranteed QoS and BE service classes, comprises: a processing circuitry configured to determine a new resource distribution between guaranteed QoS and BE service classes different from the predetermined resource distribution according to a demand for QoS service, to calculate, for each node, a new configuration indicating the new resource distribution, and to calculate, for each entry node to the network among the one or more nodes, a label distribution sequence indicating one or more label distributions with associated activation timing information so as to reduce jitter or packet loss; and a transceiver configured to transmit the new configurations to respective nodes, and to transmit the label distribution sequences to respective entry nodes.

Description

technical field [0001] The present invention relates to methods and devices for sending data from a source to a destination through one or more nodes in a software programmable network. Background technique [0002] Software programmable networks can provide guaranteed quality of service. The most common method of configuring a software programmable network is to use a centralized control entity that uses remote management to configure network features. According to the configuration of the centralized control entity, the data flow is sent from the source node of the network to the destination node of the network through the intermediate node. [0003] Consider deterministic networking (DetNet) and time-sensitive networking (TSN) to guarantee the required quality of service (QoS) using IP-based network infrastructure. In addition to services with guaranteed QoS, the software programmable network can also provide service types without guaranteed QoS, but according to a best...
