红帽全球峰会2.5. 网络
本节概述 Red Hat OpenStack Platform (RHOSP)网络服务的主要新功能。
- ML2/OVN 支持路由供应商网络
- 从 RHOSP 16.2 GA 开始，您可以使用带有 Open Virtual Network 机制驱动程序(ML2/OVN)的 Modular Layer 2 插件来部署路由供应商网络。路由提供者网络(RPN)在边缘分布式计算节点(DCN)和 spine-leaf 路由数据中心部署中很常见。RPN 允许单个提供商网络代表多个第 2 层网络（广播域）或网络段，允许操作员向用户显示一个网络。有关更多信息，请参阅网络指南中的部署路由供应商网络。
- ML2/OVS 和 ML2/OVN 的可用域
- 从 RHOSP 16.2 GA 开始，您可以使用 RHOSP 网络服务对可用区(AZ)中的节点进行分组。对于运行关键服务的节点，可以为具有高可用性的资源调度这些节点。AZ 仅支持具有 Open Virtual Network (ML2/OVN) 和 Open vSwitch (ML2/OVS) 机制驱动程序的 Modular Layer 2 插件。有关更多信息，请参阅网络指南中的利用可用域使网络资源高度可用。
