openstack openflow

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 manage their networks so that they can bette

Directory:----OpenFlow Origins----OpenFlow Basic composition,--------OpenFlow Switch,--------Flowvisor,--------ControllerOrigin: OpenFlow originated from the Clean Slate project team at Stanford University. In 2006, Stanford student Martin Casado led a project ethane on cybersecurity and management. The project view is

Five, OpenFlow table This section describes the components that make up the flow table and the group table, and also includes the mechanism of the flow table "matching" and "action" processing. 5.1 Pipeline processing Process The switches that obey the OpenFlow protocol can be divided into two categories: one is openflow-only, the other is

A network is generally composed of multiple manufacturers' switches and routers. These devices run different operating systems, have different command line interfaces and configuration programs. Can we program the network, what makes it as harmonious as playing music when managing workflows? OpenFlowTell you, you can! OpenFlow is an open-source project born after a collaboration between Stanford and Berkeley six years ago. It is based on a software-de

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 standard management interfaces and protocols simulta

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

OpenFlowWith the launch of ONF and the announcement of support from almost all mainstream network providers, the regulation broke out in the network field. This article mainly analyzes how suppliers such as HP Networking and Cisco use OpenFlow. At the Interop 2011 exhibition, many vendors were promoting their own OpenFlow switches and controllers. The popularity of these switches is self-evident. Are all ve

Protocol contention: Is NETCONF sufficient to compete with OpenFlow? OpenFlow, which has been a management and control protocol for Software Defined networks for a long time, is currently facing challenges from other protocols. Protocols that can replace OpenFlow include NETCONF, BGP, OVSDB, XMPP, and MPLS-TP. However, although these protocols can be used to man

Although OpenFlow and Software Defined network SDN are mainly about data centers or carrier networks, this technology may be more useful for campus networks, especially for the improvement and improvement of BYOD built-in devices) security and Management. Matt Davy, Chief network architect at Indiana University, believes that OpenFlow and Software Defined network can change his 0.1 million-port network, whi

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 switches have become through the OpenFlow V1.3 Conf

In Interop 2012 in Las Vegas, I asked HP two questions: what is the current situation of HP OpenFlow and software-defined network strategy? What is the progress of the HP 12500 Series Data Center rack switch? Fortunately, at the end of the meeting, I had the opportunity to communicate with Mike Nielsen, HP Network Solution sales director, who gave me some information. Here is what I know: HP 12500 is planned to be updated early next year You may have

How can I change the hardware and software to successfully deploy OpenFlow? Are there any interoperability considerations? Stephen J. Bigelow:OpenFlow deployment requires OpenFlow-compliant switches, such as HP ProCurve or IBM G8264, and OpenFlow controllers, such as the Big Network Controller from Big Switch Networks. NEC also provides PF1000 vswitches for Hype
