Openflow是什么层
OpenFlow enables network controllers to determine the path of network packets across a network of switches. The controllers are distinct from the switches. This separation of the control from the forwarding allows for more sophisticated traffic management than is feasible using access control lists (ACLs) and routing protocols. Also, OpenFlow allows switches from different vendors — often each with their own proprietary interfaces and scripting languages — to be managed remotely u… Web4 de jun. de 2024 · 近期对SDN进行了初步的认识和学习，现将自己做的笔记进行简要整理。SDN将数据包的控制和转发分离，基于OpenFlow的可编程特性，分别由Controller …

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. WebOpenFlow flows are mapped to filter terms, and OpenFlow controller requests to add, delete, and modify flows result in the addition, deletion, or modification of terms in the …
Web19 de jul. de 2015 · Short version: it doesn't. Longer version: Openflow is just a protocol for communicating between the 'forwarding units' and a controller. It is the controller itself that determines what to do with packets, and it can do this in any way it likes.
