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.

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

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

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 network cable, the impact of application traffic throughput on the network is difficult to control, and network adjustment also lags behind. The emergence and concept evolution of Software Defined Network (SDN) began to change the current situation of Network passive, so that the Network can be Defined flexibly; this definability means that the network actively "processes" the traffic, not just passively "carries" the traffic, but makes the relat

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

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

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

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

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

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

Wen/Shanyi Air Marketing Director, Spruce Network The "Global SDNFV Technology conference", which ended June 2, 2016, brings together global authority organizations, operators, manufacturers and enterprises, focusing on carrier networks, enterprise networks, and cloud data centers. From keynote speeches, user exchanges and product testing, there is a message: "SDN is no longer a concept, and the urgent need and the land of the industry have come true

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

The control layer is the SDN brain. It is responsible for centralized and unified control of underlying forwarding devices and provides interfaces for calling network capabilities for upstream services. It plays an important role in the SDN architecture, SDN controller is also the focus of SDN. In terms of technical im

In the next few years, carriers will use SDN technology to enable their man and wan to carry cloud services. Therefore, they need a multi-layer SDN architecture to optimize the routing network and transmission capabilities, this increases the flexibility, scalability, and efficiency of man and wan. Preface Cloud Computing technology has completely changed the design and operation of data centers (iDCs.
