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.

protocol of H3C. Based on the SDN Architecture concept, H3C implements a more flexible user-defined network design and implements a new OAA business model, allowing you to flexibly implement custom network functions. Based on OAA, two open interface models are proposed, as shown in figure 9. Figure 9 the left figure shows a fully loosely coupled OAA architecture. Network services running in any form of user may be computing services on servers (such

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

(or marketing materials) are used for security? Is Security something dispensable, or is it part of the solution architecture? Does this solution not require security protection in the firewall? Too many products think that there is no Internet-oriented system to enjoy magic-like security protection. For combined SDN and other composite solutions, how does the consortium network manage the trust relation

SDN only applies to data center sdn technology is explored for or around data centers (for example, " I was able to launch a set of virtual machine systems in a few minutes, but why network / firewall changes in a few weeks ") , wan and Campus network. It should be emphasized that wan is the culprit that has led many customers

Use NFV and SDN to implement 5G network slicing and nfvsdn5 g Slicing Network Slicing Network slicing will play a key role in the implementation of 5g, which allows operators to run multiple virtual networks on a single physical infrastructure. With the 5g commercialization in 2020, many people are wondering to what extent network function Virtualization (NFV) and software defined network (SDN) can extend.

specific mode and set the threshold value of data packet capacity from one or more sources within a specific period of time. These switches can then discard the data packet or redirect it to another destination using other technologies and protocols. Most routers and other network platforms do not have such a detailed control mechanism. 2. Attacks against specific applications and services: these attacks only target Web services with very special HTTP request sequences (using user proxy strings

design is the application that provides services (such as exchange/network virtualization, firewall and traffic balancer. (Note: The openflow-Based Load balancer is called a traffic balancer. They are not traditional load balancers because they cannot read packet content.) These applications are similar or identical to those in scenarios where the software runs on specialized hardware. Most of the coming innovations in network technology will take pl

as BGP-LS and PCEP, the original concept of PW on the router, L3VPN, mpls te tunnel, etc. are still retained, but the running mode has changed. The problem of "low intelligence" has been greatly improved through SDN. NFV promotes "generalization" of network functions" The introduction of SDN is only the starting point of change, while the introduction of NFV (network function virtualization) makes this cha

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

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 OpenStack, mainly using the release so

' needs at any time. to match these changes, the data center network must be equally flexible, agile, and scalable. It must be automatic. As users demand resources, cloud computing can create virtual machines in a very short period of time. The network must respond quickly and match with it. Configure your own resources to process the required routes to meet the connection requirements. To ensure that all of this can run without human intervention, cloud and network must be able to use the same

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

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
