Neutron Introduction: https://www.ibm.com/developerworks/cn/cloud/library/1402_chenhy_openstacknetwork/Neutron itself is not an SDN architecture, but does not hinder its integration with other technologies into the SDN architecture, including the new Plguin in Ryu, Opencontrail, and the corresponding SDN controller to transform the neutron architecture into an

Traditional networks are now unable to meet increasing user demands, and traditional networks require fundamental refactoring and change, and these changes are being driven by software-defined networking (SDN).Opendaylight (ODL) is a multi-Protocol SDN deployment controller architecture that supports high availability, modularity, scalability, scalability, and resiliency in a modern, diversified vendor netw

Challenges faced by Carrier Networks in SDN (i)Babak Samimi A software-defined network that separates the data plane, the control plane, and the management plane (SDN) Improved theOPEXandCAPEX, and it makes it possible to centralize the deployment and management of network resources--SDNThese strengths are well known. BecauseSDNThe centralization of network resources creates a platform that is easy to manag

The basic concept behind OpenFlow and SDN is that as long as SDN-friendly switches emerge, the Controller and application environment will flourish ". In addition to SDN-friendly switches, SDN has more obstacles to overcome-complexity. One of the goals of SDN is to decouple

SDN technology transfers network control to a dedicated SDN controller, which manages and controls all functions of virtual networks and physical networks. Because SDN security policies implement such isolation and control, it supports deeper packet analysis, network monitoring, and traffic control, which is very helpful for defending against network attacks. The

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 a term used to describe the highly automated configuration of network s

Neutron and SDN integration status analysis I. Summary of Neutron In general, Neutron is one of the core projects in many OpenStack projects and represents its network services. Since its birth, Neutron has been named by nova-network and changed to quantum. Due to its conflict with the name of a company, the tunnel has changed to Neutron. On the surface, the naming changes do not imply its profound development and evolution. With plug-in, advanced net

It is reported that Huawei, ZTE, China Three communications, Cisco, intel , freescale , , Ruijie, ixia , think Bollen, netronome , windriver and other top dozens of global manufacturers will appear on the scene of the conference, sdn , NFV and other future network technology development status and enterprise strategic deployment presenta

Brocade announces the launch of the second generation of Open Source SDN controller, which is based on the lithium version of Opendaylight and adds two new management applications, enhancing support for SDN operations.Brocade claims that the Vyatta controller is a commercial version of the Opendaylight controller, which is upgraded on a vyatta basis, focusing on increased support for OpenStack, enhanced vir

The Controller is responsible for centralized control of the entire SDN network and plays an important role in grasping the resource view of the entire network and improving network resource delivery. However, the centralization of control capabilities also means that the security and performance of the controller board become the bottleneck of the whole network. Once the controller is not guaranteed in performance or security, the downgrading or even

Tame your WAN: Apply SDN to the WAN and wansdn The network should have responded to the needs of users and applications. However, for a long time, the network does not meet our needs well, and the network forces users and applications to adapt to network restrictions. In enterprises, the IT department has been striving to ensure that the network security capability is consistent with the development of devices and applications. In the WAN, bandwidth

How to embed SDN and automation into the next-generation cloud data center In the cloud computing era, enterprises need a new data center network architecture. The new network architecture mainly refers to the use of software defined networks and network automation platforms to build a data center network architecture. The image of hardware manufacturers is deeply rooted in the hearts of the people. In recent years, Dell has also acquired more than $

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

Container Network: An SDN system designed for developers What is the difference between a container network and a traditional SDN? The SDN system is still in the development stage. It is often created as a logical version of a physical network. It is connected to a logical network switch through an abstract port, network, or subnet, and to a virtual machine. As a

Editor's note: With the deep development of cloud computing,SDN and NFV have been on the ground in the world with cloud-like concepts, and have a certain scale of application in enterprise network and telecom network, but standardized, Security issues are becoming more prominent. The "NetEvents2015 Global Cloud Computing Innovation Summit" was held in San Francisco, USA, and the summit gathered all aspects of the cloud computing industry chain, includ

The ultimate goal of SDN networks is to serve diversified business application innovations. Therefore, with the deployment and promotion of SDN technology, more and more business applications will be developed. Such applications will be able to conveniently call the underlying network capabilities through the SDN Northbound Interface and use network resources as

What is the relationship between East-West traffic and SDN? The relationship between East-West traffic in the data center and SDN is reflected in the fact that many SDN solutions are designed to address the challenges posed by such dynamic traffic. There is no shortage in the network industry to discuss the relationship between East-West traffic and
