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.

application and traffic changes can be achieved, you do not need to rely solely on the hardware and software upgrades of equipment suppliers over a long period. The idea of SDN is to give more control to network users. In addition to design, deployment, and configuration changes, SDN software can also be reconstructed so that new technical verification can be performed before commercialization. This networ

Foundation, ONF, ODL and Onos, etc.) are also strengthening the relevant standards and industrialization promotion. SDN has entered a critical period of rapid business model deployment and is about to usher in a golden age. 2. SDN and NFV converge As the "brother" of Sdn, NFV focuses on the 4~7 layer of the network, i

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

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

proportions were44%、29%、8%And3%; inSaaSaspect, the proportions were42%、27%、16%、7%。 As a result, cloud computing presents a multi-service provider, in which case it is important to get through the boundaries between different cloud services and to facilitate interoperability and sharing between different cloud services, which demands a unified standard.For ONF manager Mike McBride , the biggest benefit of standardization for

architecture model is currently the most popular and well-known in the industry. It introduces an SDN Controller based on the mechanism controlled by traditional devices. The underlying devices only need to be responsible for traffic forwarding, among them, there is a valuable interface protocol-OpenFlow, which has evolved a lot from HP's cooperation with Stanford's Ethane project to the latest version 1.3.1 ,. Of course, in addition to the

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.

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

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

In the SDN standard system developed by ONF, in addition to OpenFlow switch specification pairs, there is also a Protocol named OpenFlow Configuration and Management Protocol (OF-CONFIG) also needs to be concerned. As mentioned above, OpenFlow defines a kind of southbound interface in SDN network architecture, and proposes a method for the Controller to send a fl

How to transition to SDN? First, you need to know what a software-defined network is and what it can do for you. Then, you need to understand the internal working principles of SDN controllers, the differences between well-known suppliers and products provided by startups, and whether open-source and bare metal switching can be used as a choice. Finally, understand your own network, such as whether it suppo

The group task of the recent advanced online course is to study and present the topic at your discretion within the scope specified by the teacher. We selected SDN for the group. I thought it would be a conceptual product that no one cares about in the industry. Google found that SDN is very popular because of its scalability, some large Internet companies are also getting involved in related R D, such as

AbstractThe explosive scale of container CPUs needs highly efficient network virtualization Challenge the Number of container-based CPUs Would be 10-100 multiples up over that of hypervisor-based virtual machines; Cloud networking needs upgrade to fit the explosive scale of containers Question can SDN standards, e.g., openflow , support highly efficient network Virtualization for containers ' networking? DaoliCloud ' s Positive

A key challenge for software to define network potential users is to judge the specific value of a particular SDN controller, which, after all, plays a key role as a bridge between network applications and network infrastructures. However, there is no model to standardize SDN, and there is no standard that a SDN controller must comply with. Although the advent o

Theoretically, SDN technology should bring about a safer network. Because, through virtual networks to programmable stacks, the network will become more flexible and operations should be more automated, which should mean less "fat finger" disaster. However, for any interconnected system, when we allocate basic operations to software, we also introduce new risks. When we connect servers to the internet, we know that some servers will be attacked, so we

SDN and cloud security challenges-important role of visibility SDN is designed to transform modern networks and data centers into highly agile frameworks that can be quickly reconfigured based on changing business needs. Although SDN is still unfamiliar to the public, almost all organizations are developing plans for this purpose, to adapt to this claim, we can a

Editor's note: At present, both the Internet and the telecommunications industry, the acceptance of SDN is increasingly high. However,the business ofSDN still needs to address a range of challenges, especially from non-technical areas. at present, the acceptance of SDN is becoming more and more high both in the Internet and in the telecom industry. However,the business ofSDN still needs to address a range

In 2013, we saw a lot of new SDN products, architecture, marketing activities and conferences. Some new standards and open-source organizations also entered this field. At that time, SDN had just returned from the high point of the hype cycle. In the twinkling of an eye, in 2014, we will see the adoption of real products, including the development and deployment of multiple industries. What really matters i
