面向垂直行业专网的确定性SLA指标分级研究

Deterministic service level agreement:indicator classification in private networks for vertical industry

以经济有效的方式满足不同行业客户差异化的确定性服务质量体验,有利于推进垂直行业确定性专网建设。面对多种细分行业不同维度的确定性服务质量需求,服务等级协议(service level agreement,SLA)指标的分类分级十分重要。首先总结了垂直行业中多种类型确定性服务的应用场景,并对各类型业务进行了指标需求分析。然后,提出了确定性SLA指标体系并总结了各指标的分级设计方案,解决当前网络SLA指标对于确定性属性体现不足的问题,帮助降低行业客户和服务提供商之间的指标理解对齐难度,使得网络能契合不同行业的确定性服务需求。最后,对未来的工作进行了展望。

Meeting the differentiated deterministic service quality experience of customers in different industries in an economically effective manner is conducive to promoting the construction of a vertical industry deterministic private network.In the face of various segmented industries and different dimensions of deterministic service quality requirements,the classification and grading of SLA(service level agreement)indicators are very important.Firstly,various types of application scenarios of deterministic service in vertical industries were summarized,and indicator requirements analysis was conducted for each type of business.Then,a deterministic SLA indicator system was proposed and a hierarchical design scheme for each indicator was summarized to solve the problem of insufficient reflection of deterministic attributes in current network SLA indicators,and help reducing the difficulty of understanding and aligning indicators between industry customers and service providers,and enable the network to meet the deterministic service needs of different industries.Finally,prospects for future work were presented.
