interface between the Wanstax API and the OpenFlow controller. Wanstax runs and emits API function calls, which seem to run on that target, and in fact, the OpenFlow Wanstax controller interface translates API requests into OpenFlow messages and sends them to OpenFlow switches running on the target. The

The Open VSwitch (hereinafter referred to as OVS) is a virtual switch run on a virtualized platform (such as Kvm,xen), which is led by Nicira Networks. On the virtualization platform, OVS can provide 2-layer switching function for dynamically changing endpoints, and it is very good to control access policies, network isolation, traffic monitoring and so on in the virtual network.OVS complies with the Apache 2.0 license and can support multiple standar

In recent weeks, with the activation of the Open Networking Foundation (ONF) and the announcement of support for almost all mainstream network providers, the OpenFlow specification broke out in the network field. In fact, the OpenFlow switch has been published on Interop Las Vegas 2011 and has aroused great controversy. SDN allows network engineers to control and

and network processor for many years to do the same thing as OpenFlow. In addition, opening the forwarding plane of different vswitches from multiple vendors also causes thorny security problems. However,ASIC vendors seem not worried about OpenFlow.In fact, they welcomed this. Broadcom CTO Nick Ilyadis said, "Broadcom is part of the work involved in defining OpenFlow. Both

have all realized that to manage networks across multiple data centers, and this network is not owned by the enterprise, this management difficulty is very complex, even though we are making progress in all other aspects. "The simpler the network management requirements, the better. I think the future vision proposed by the SDN movement and OpenFlow promoter Open Network Foundation may be the best way to achieve this goal. But other factors are also

the network giant is one of the members of the Open Networking Foundation, I still cannot find its plan for OpenFlow. Cisco may think that OpenFlow damages IOS software as a profit-making product. The most prominent advantage of OpenFlow is to reduce the cost of hardware switches, rather than improving the sales of network providers. Avaya: although the company

Many people don't understand the difference between openflow and software-defined networking (SDN). Not surprisingly, because the two technologies are closely related, many people have such doubts. However, they are not interchangeable. OpenFlow is a protocol that uses processes such as APIs (application programming interfaces) to set up network switches. SDN is a term that describes the high degree of auto

OpenFlow can provide communication between controller software and devices, the two Protocols are completely different in many aspects. NETCONF is a configuration protocol, while OpenFlow only specifies how data packets are transmitted through routes in the process table. OpenFlow switches use OF-Config for configuration, while OF-Config uses NETCONF to communic

can select security rules based on specific device types. Davy believes that the network can be completely transitioned to an OpenFlow environment to achieve this ideal state. In this case, he can create a "virtual access layer" to map the physical access layer, but also manage it through the central SDN controller. Then, Davy's team can start virtual network segments across components in both wired and wireless networks, so that the SSID can be set

Huawei Agile Switch S12700 formally passed the OpenFlow v1.3 conformance Certification test of the Global SDN Test Certification Center, the world's leading information and communications solutions provider, and became the first box-type product in the world to pass the certification. This test also passed the S6720-ei, s5720-ei box switch, Huawei S-Series switch

One, openflow to solve what problem?1. First, a brief introduction to what is SDN, the traditional network is the computing route of each node itself, SDN is centralized control of the route. In a data center network, there is only one controller, the following can be connected to multiple switches. After the controller has calculated the route, the flow table is sent to the switch, and the
