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

Relationship between SDN and intention-Based Network (IBN), and sdn intention Network (ibn) Compared with SDN, the intention-Based Network (IBN) is somewhat immature. Although it is also a technology that changes the network industry, what is the relationship between the two? SDN and intention-based networks are simil

standard branching-backbone fiber to form an open network architecture that leverages Onos, Xos, and OpenStack to form an open-source platform, Cord delivers the economy and cloud agility of telecom services. AT/T in 2015, it moved 5% of its business to the cord architecture, with a 2016-year plan to migrate 30%, with the ultimate goal of transforming itself into a software company. Enterprise CORD (E-cord) cut into the specific business scenarios, r

SDN changes the router technology development path, and sdn changes the router path Over the past 30 years, IP networks centered on routers and switches have always followed Moore's Law to build a modern information civilization with other IT devices. As the core device at the WAN and LAN egress, routers have always played a key role and have undergone continuous development and numerous upgrades. Today, t

the cloud platform (for example, code logic directly implemented in OpenStack Neutron Server ). Controllers in this scenario cannot be used as general SDN controllers. On the contrary, General SDN controllers cannot be directly used in cloud computing network scenarios. As for the second question, it is easy to understand why it is a misunderstanding. Even contr

network virtualization with SDN. To use SDN, you do not need to change the network configuration using manual processes or the command line interface. You do not need to hire professional network engineers. You only need to ask some developers to integrate the following functions in an automation system: Get the application management-level hierarchical command and send it to the Controller, while no progr

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 developm

in the network industry will make all these services a reality and be simpler and more automated. However, we also need to face new challenges: applications, content developers, and end users do not want to regard the network as what they need to know. For a network engineer, this means that eventually an application or workload sends a signaling to the network, telling the network user what "experience" they expect through their own applications and services ", then the network can meet the us

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

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.

southbound interfaces and virtualizes resources, meanwhile, flexible northbound interfaces are provided for upper-layer businesses to configure networks and call network resources as needed. The well-known OpenStack in the cloud computing field is a cloud management platform that can work at the SDN application layer. By adding an SDN management plug-in to its n

VMware NSX) support the deployment of containers in their SDN products. Other vendors supporting the container network are: Microsoft, Google, HP, Juniper, Nokia (Nuage), Pluribus, BigSwitch, PLUMgrid, and Midokura. From a container software perspective, companies such as Docker, Canonical, Red Hat, and CoreOS are working to improve the network capabilities of their containers. Advice to IT leaders containerized is rapidly becoming an important part

Editor's note: Sdn-ip is an application on Onos that allows software-defined networks to connect to external networks using standard Border Gateway Protocol (BGP). From a BGP perspective, the SDN network behaves as a single autonomous system (as), with the same behavior as any traditional as. The SDN-IP application based on as provides an integrated integration m

, can realize the automation of network access, greatly improve the work efficiency. In addition, Brocade has made improvements to prevent DDoS attacks, enabling network devices to be linked to security devices. "With SDN, many functions can be done on the controller, and the flexibility and adaptability of the network are greatly enhanced." In addition, the Controller for SDN also has a number of supportin

manufacturers. Security and said, with third-party security manufacturers to achieve 5-7 layers of security, NSX firewall can only do 2-4 layers. With load balancing, F5 can deploy a distributed deployment in addition to the deployment of a single-arm mode, online mode. This function is very cow, and can use all the advanced features of F5.Another important integration is the integration with Openstack,nsx-v and
