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.
Many people do not understand the difference between openflow and Sdn. It is not surprising that these two technologies are closely related, so many people have such doubts. However, they are not interchangeable. Openflow is a protocol that uses a process like an API (Application Programming Interface) to set up a network switch.
SDN is undoubtedly the most popular keyword in the network field in 2013, but more is the concept hype. Many vendors have published their own SDN products and strategies, however, only a few released products are commercially available. In 2014, the SDN technology will make a great leap, and more products will be deployed and ready. By interviewing several indust
SDN (Software Defined Networking) SDN is not equal to OpenFlow, its relationship is similar to the Internet is not equal to IP protocol, PSTN is not equal to 7th signaling, IMS does not equal to the sip,web system is not equal to the HTTP protocol. OpenFlow is only the SDN c
Recently has been learning Ryu controller, in the process of use, found the following aspects of the advantages: Ryu controller is written in Python language, in the understanding and speed is very fast; The Ryu controller's overall architecture is clear, In the future, I will organize an architectural article about the Ryu controller for your reference; The Ryu controller itself is a powerful network experimental platform that is very well compatible with OpenStack and is not very familiar to O
in the SDN architecture. The network operating system and upper-layer applications constitute a control layer. The data forwarding and control layers are decoupled using a standardized interaction protocol, which is currently OpenFlow. This decoupling architecture indicates that network operating systems and network applications (such as routing control protocols) do not have to run on physical devices, bu
What exactly is SDN? Although the concept has been fired for many years, no one has yet given a clear idea of it. On the internet also emerged a lot of excellent articles on SDN thinking, adhering to the "do high-quality content porter" idea,Sdnlab June collected some of the following articles to share with you. Make it possible to have a more stereoscopic understanding of
About routing service in OpenFlow Network (1) Here, the so-called OpenFlow network refers to a set of OpenFlow switches connected to each other, and all these switches are placed under the management of an OpenFlow Controller or an OpenFlow Controller cluster. The routing

APIs and various message protocols, including some standards, allow users to build today's Software Defined Network (SDN ). However, the key issue is that not all people can achieve the same network, or they can achieve it in the same way. So,OpenFlowCan we lead all of us to the SDN Park in the same way? OpenFlow is an open-source API that allows you to program t
Openflow switch Application Mode Researchers at Stanford University proposed that Openflow had two original intentions: first, they needed to conduct innovative network research and wanted to separate the control layer functions of network devices from physical devices, to control and modify the behavior of network devices through programming as needed. Second, we hope to build a new universal network data
assumed that the physical topology of the network can be separated, network resources can be virtualized, the complexity of the physical structure can be hidden, and the management and control of the logical layer can be unified to meet the changing network needs. SDN and openflow are the same solutions.Openflow and SDN Open
, hardware deployment can be done even between the completion of a standardized work for a particular protocol. This is critical to accelerating new technologies like carrier-grade OpenFlow-based Sdn.4.2 Control channel: Asidua's Wanstax product lineAsidua's Wanstax product line provides customers with a complete set of control channel software, thus accelerating the development of network services.With the
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

Know the similarities and differences of these products: physical/virtual network coverage, network virtualization layer, OpenF
so on. The only difference is that there is no need for IBGP peerings between Sdn-ip instances, they only need to interconnect with BGP speaker.SDN-IP implements a subset of the IBGP protocol: receives only BGP routing information from BGP speaker, but never initiates or re-sends BGP routes. Once the SDN-IP receives a notification from an external router (received via BGP speaker), it transforms the routin
be in trouble. After all, the software definition network is developing rapidly, and the initial overall solution will look stale. So we have a number of factors to consider, as detailed below. Raw Performance When it comes to raw performance, we first need to be clear about the role of the SDN controller. Generally, the function of the SDN controller is to separate the control of the network environme
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
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

HP and F5 are working together to implement an automated application distribution solution that supports Layer 2 to Layer 7 networks. So far, the cooperation results have been confirmed to support Microsoft Exchange, server virtualization and disaster recovery. This technology can help network engineering abandon the CLI), allow them to use
