Description
本申请涉及通信技术领域,尤其涉及一种资源管理方法及装置。
随着移动通信技术的发展,下一代移动网络将扩展支持新的不同类型的客户和合作伙伴。运营商将支持垂直产业,共享基础设施、开放特定网络功能,并将合作伙伴强大丰富的软件能力集成到下一代网络系统提供端到端服务。为了建立多层面的合作关系,网络切片(Network Slice)将是下一代网络满足不同行业、不同用户对网络具有超特殊需求时的重要技术手段。
为了满足不同的租户需求,保证不同租户的服务水平协议(Service Level Agreement,SLA),运营商需要将网络切成不同的网路切片来满足不同的租户需求,并从管理面上单独管理端到端(end to end,E2E)的网络切片。
虚拟化是网络切片部署的一个重要条件,虚拟化环境下设备商只是负责提供业务软件资源,平台资源(例如,硬件资源、虚拟资源)是由第三方厂商或者运营商提供的,并由管理和编排单元(Management and Orchestration,MANO)负责对虚拟资源的管理和编排,其中,虚拟资源包括但不限于计算资源(Compute resource),存储资源(Storage resource),网络资源(Network resource)等。设备商需要向MANO申请虚拟资源来完成相应的软件资源部署。
目前,在虚拟化环境下,如何管理网络切片的虚拟资源的申请和分配等操作,还没有明确的解决方案。
