Problems solved by technology

In this method, it is fixed to start from the first time slice, so that the intention configured in the previous time slice is configured in the current time slice, so that the intent of the current time slice has more intentions with greater weight and cannot be configured, which affects the intention on the entire time slice The number of configurations occurs; and it does not consider the resource usage of time-varying intentions in the entire time domain, so that the resource occupancy of intentions varies greatly in different time slices and affects the number of configurations of intentions

Embodiment Construction

[0120] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.

[0121] The technical problem to be solved by the present invention is: on the premise that the expression intent is connection, time-varying intent related to network service function and QoS, and the underlying network resources are known to be limited, and the intent granularity is group granularity, configure the time-varying intent, And try to make the number of time-varying intent configurations as large as possible. F...

Abstract

The invention discloses a time-varying intent configuration method in an intent network, and proposes a heuristic algorithm, which is a greedy algorithm (MSP) based on maximizing a single time slice configuration, and is used to solve time-varying intents that support multiple strategies. For the configuration of intentions, the MSP algorithm is mainly composed of a time slice selection algorithm and a single time slice configuration algorithm. The time slice selection algorithm is used to determine the order of each time slice configuration according to the total weight of the intent in the unconfigured time slice, and then a single time slice configuration algorithm is used to consider the resource usage of the intent in the entire effective time. The intent in the slice is configured. It can be applied to configure time-varying intents with different priorities, and has the characteristics of short time-consuming configuration solution and high intent configuration success rate.

Description

technical field [0001] The invention belongs to the technical field of intent network, and in particular relates to a configuration method of time-varying intent in intent network. Background technique [0002] With the gradual deepening of software-defined networking (SDN) and network function virtualization (NFV) research, network users have increasingly urgent needs for simplified network use and management. The new network structure that automatically realizes and maintains the required network goals has gradually become a research hotspot in the field of software-defined networking. [0003] The intent network is a new type of network architecture, in which the intent interface can be provided for the network users, and the network users can express the network requirements they want to realize through the intent interface. Users inform the network of their own needs, that is, their intentions, and the network automatically realizes and maintains this intention. Users...
