舰艇网络业务种类多，工作环境复杂，传统的组网方案倾向于划分为作战/通信/平台等若干个分散部署的专用网络，专用网络体制之间的不兼容带来了整个舰艇网络架构的臃肿、互联互通的困难和可靠性上的降低。为了解决这些问题，需要研究新一代的、采用统一的高可靠性的扁平化网络架构，以实现多种业务在统一网络平台上的分布式接入、交换和路由。本文借鉴成熟的商用IP网络的组网技术，针对舰艇网络的特定需求，讨论了2种高可靠性的组网方案，即设备堆叠和MPLS EVPN，并通过故障恢复时间试验，对它们进行分析和比较。试验证明，这2种组网方案各有优缺点，但都能更好地满足舰艇网络的组网需求，具有广泛的应用前景。
There are many kinds of shipboard network services and complex working environment, the legacy networking schemes tend to be divided into operational/communication/platforms and other decentralized dedicated networks. The incompatibility between the specialized network systems brings about the bloated structure of the whole shipboard network, the difficulty of interconnection and the reduction of reliability.In order to solve these problems, it is necessary to study a new generation of flat network architecture with unified high reliability to realize distributed access, switching and routing of various services on unified network platform. According to the specific requirements of shipboard network, this paper draws lessons from the mature networking technology of commercial IP networks, and discusses two kinds of high reliability networking schemes, namely, device stacking and MPLS EVPN, and analyzes and compares them through fault recovery time test.The test results show that the two schemes have their own advantages and disadvantages, but they can better meet the needs of shipboard network, and have a wide application prospect.
