网络切片资源信息的收集方法、装置及存储介质
相关申请的交叉引用
本公开基于2021年4月25日提交的发明名称为“网络切片资源信息的收集方法、装置及存储介质”的中国专利申请CN202110449433.5，并且要求该专利申请的优先权，通过引用将其所公开的内容全部并入本公开。
技术领域
本公开涉及通信领域，具体而言，涉及一种网络切片资源信息的收集方法、装置、存储介质及电子装置。
背景技术
随着5G无线网络的大规模部署，用于5G回传网络的网络切片技术也处于快速发展中，根据国际标准组织互联网工程任务组(Internet Engineering Task Force，IETF)的草案draft-ietf-teas-ietf-network-slices的定义，网络切片是一个连接了大量端点的逻辑网络拓扑，该逻辑网络拓扑使用一组共享的或专用的网络资源来满足特定的业务等级目标(Service Level Objectives，SLOs)。网络切片技术在转发平面主要有两种实现方式，第一种实现方式是在数据报文中插入一个专门的切片ID(标识)，网络节点在转发数据报文时，通过切片ID来把数据报文与该数据报文所属的网络切片关联起来，这里的切片ID在不同的切片技术中可能有不同的名称，例如也可能被称为虚拟传输网络ID或多拓扑ID，等等；第二种实现方式是在数据报文中插入与切片ID绑定的转发ID，网络节点在转发数据报文时，通过转发ID来把数据报文与该数据报文所属的网络切片关联起来。图1是相关技术中的携带切片ID的IPv6报文封装格式示意图，如图1所示，IPv6切片ID被插入到IPv6数据报文中，用于网络节点识别该报文所属切片。图2是相关技术中的携带与切片ID绑定的转发ID的IPv6报文封装格式示意图，如图2所示，IPv6数据报文的IPv6目的地址是与某个IPv6切片ID绑定的，而且该绑定关系已通过控制平面或管理平面通告到了每一个网络节点，用于网络节点识别该报文所属的网络切片。
无论采用哪种转发平面的实现方式，网络切片技术都要求网络节点在转发数据报文之前，为网络中每一个网络切片预留专用的转发资源，这样在网络节点接收到数据报文之后，就会使用为该数据报文所属的网络切片预留的转发资源，对该数据报文进行转发。但是，目前缺乏一种有效的方法，能够收集网络切片相关资源信息，以实现对网络节点实际转发行为的监控和分析。
针对相关技术中存在的无法有效收集网络切片资源信息的问题，目前尚未提出有效的解决方案。
