靠谱的SDN与不靠谱的OpenFlow - 腾讯云开发者社区-腾讯云
WebOpenFlow is an open interface for remotely controlling the forwarding tables in network switches, routers, and access points. Upon this low-level primitive, researchers can build networks with new high-level properties. WebOpenFlow was one of the first widely used protocols for enabling SDN. However, OpenFlow also has disadvantages, for example: i) Internet service providers cannot choose specific functions, although not all functions are always needed, and thus costs are high; and ii) each new OpenFlow version requires new hardware. Therefore Bosshart et al. … Web13 de abr. de 2024 · 第四章云网络4.8.1节——SDN总述; 第四章云网络4.8.2.1节——OpenFlow ... 2.2 Docker镜像加载原理. docker的镜像实际上由一层一层的文件系统组成,这种层级的文件系统UnionFS ... dewalt cross line laser green
