SPN Channel OAM的研究与实现

Research and Implementation of SPN Channel OAM

切片分组网(SPN)是基于多层融合的新一代端到端分层交换网络,具备业务灵活调度、高可靠性、低时延、高精度时钟、易运维、严格QoS保障等属性。SPN Channel作为网络中的一条源宿节点之间的传输路径,用于在网络中提供端到端的以太切片连接,因此SPN Channel需具备网络级的OAM故障检测手段和性能管理能力。在SPN Channel的基础上探究故障检测OAM的具体实现是本次研究的主要目的,通过研究SPN Channel OAM技术要求以及OAM码块的特点,提出了一种SPN Channel OAM的实现方案,实验证实了该方案具有SPN Channel OAM故障检测和性能管理的能力。

The Slice Packet Network(SPN)is a new generation end-to-end layered switching network based on multi-layer convergence.It has the attributes of flexible service scheduling,high reliability,low latency,high-precision clock,easy operation and maintenance,and strict QoS guarantee.The SPN channel acts as a transmission path between a source and sink node in the network to provide an end-to-end Ethernet slice connection in the network.Therefore,the SPN channel needs to have network-level OAM fault detection and performance management capabilities.Based on the SPN channel,the specific implementation of OAM is the main purpose of this research.By studying the OAM technical requirements of SPN channel and the characteristics of OAM code blocks,to proposed an implementation scheme of SPN channel OAM.The experiment confirms the scheme has OAM fault detection and performance management capabilities on SPN channel layer.
