Deterministic network-oriented network slice generation and dynamic configuration system and method

Abstract

The invention relates to the field of Internet, and discloses a deterministic network-oriented network slice generation and dynamic configuration system and method. The deterministic network-oriented network slice generation and dynamic configuration system comprises an information acquisition module, a software control module and a network transmission module. According to the network slice generation and dynamic configuration method, link space division is carried out on a network layer, bandwidth resources of deterministic services are guaranteed, division of network slices is achieved through a network slice algorithm, network resource reservation and division based on deterministic service flows are achieved, and the network slice generation and dynamic configuration efficiency is improved. Moreover, time slot scheduling is carried out on the flow in the deterministic network virtual slice, so that network congestion queuing and resource snatching caused by simultaneous arrival of multiple deterministic data flows at an end node are avoided, bandwidth division of deterministic services is carried out from the time dimension, the slice flexibility is improved through time slots, and the efficiency of bandwidth division of the deterministic services is improved. And if the services are different, adjustment can be carried out through the time slots without resetting the slices.

Description

technical field [0001] The invention relates to the Internet field, in particular to a deterministic network-oriented network slice generation and dynamic configuration system and method. Background technique [0002] At present, with the increasing number of applications such as Industry 4.0, remote driving, and remote surgery, the requirements for ultra-low network latency and micro-jitter are getting higher and higher. Among them, the industrial Internet of Things requires an end-to-end delay of microseconds to milliseconds, and a jitter of a microsecond; the tactile Internet (remote surgery) requires an end-to-end delay of 3-10ms, and a jitter of no more than 2ms; The end-to-end delay is 100-250 μs, and the jitter is several microseconds. Remote driving requires not only low latency jitter, but also higher transmission rates. In order to meet the network requirements of the above applications, time sensitive network (TSN) and deterministic network (Deterministic networ...
