OpenFlow Switch Specification - Open Networking Foundation

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… Web9 de jan. de 2013 · OpenFlow and NetFlow are two completely different concepts. OpenFlow controls how packets are forwarded through network switches, and Netflow collects IP traffic information. It’s easy to think of the two as being related because both words contain the suffix “flow”. This post should provide some clarity on the nature of … 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. ips bono kicillof
