technical field

The present disclosure relates to the technical field of data communication, and in particular to a service level agreement (SLA) indicator decomposition method, device, system, equipment, medium and computer program product.

Background technique

Network slicing technology is a key technology for 5G networks to provide differentiated services for different application scenarios. Through network slicing, operators build multiple dedicated, virtual, isolated, and on-demand logical networks on a common physical platform to meet the different needs of users in different industries for network capabilities (such as delay, bandwidth, connection number, etc.). Clear SLA indicators help industry users intuitively feel the service types and differences that network slicing can provide, and refer to the service levels defined by SLA standards to choose network slicing services that suit the business characteristics of their industries, thereby reducing inter-industry barriers to communication. As a service agreement for providing communication services, the network slicing SLA needs to transmit the service demand information signed by the operator and the network slicing customer to the operator's network. For a scenario where a new slice needs to be created, the slice management system bases the tenant on the slice's SLA requirements (such as slice list, PLMN list, maximum number of users, slice service area, slice end-to-end resource sharing level) to decompose the SLA of each domain (access network, transmission network, core network, etc.), and then configure resources in each domain, including bandwidth, delay, etc.

The existing SLA (Service Level Agreement, service level agreement) decomposition method is mainly completed by using the horizontal cross-domain linkage of the controller. This method is based on the fact that the end-to-end network is composed of network domains with different functions (access, core, etc.) This is the premise of horizontal splicing in order. However, this solution does not involve the mapping and decomposition of the longitudinal SLA indicators between the outer slice and the inner slice (subnet slice) in the hierarchical network slice scenario.

It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art.
