other is the TCP/IP concept (let alone OSI). To see the essence, I still have to look at history. In this regard, I do not agree with the view of Black Swan, not just because I like history! TCP/IP standards and OSI standards are essentially no different, but TCP/IP sets up a profit. In essence, they are all layered models. To view the history, we have to start with OSI, after the OSI Standard is generated, take a look at the battle of faarus or the Battle of Phillips and akaxing as to how TCP/

security is low, the two are indeed a pair of contradictory body which is difficult to weigh.Aside from these contradictions, the standardization ofSDN and NFV propulsion has some problems to solve. At present, the south-to-interface protocol has evolved and diversified, and the industry has put forward many control protocols such as OpenFlow, Pcep, netconf, BGP, etc. OpenFlow agreement itself is still evolving, from the v1.0 to the v1.5, the conten

Future,DPIcan be reduced by marking or transmitting end-to-end information, as in the recentIETFDraft by joining the Network Service header (NSH) Recommendations for enhanced recommendations. There are also some workarounds for the idea of using tags/tags, configure channels, and so on. OpenFlow expansion requires l4-l7 devices openflow as SDN South protoc

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 ONF Organ

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

How DCN and SDN meet new requirements New Technology of ip ran Network The traditional 3G/B3G network needs the basic bearer network to provide the Layer 2 capability to meet the needs of the Upper-layer network mobile service return. However, due to the introduction of S1-Flex and X2 interface, the basic bearer network must have three-layer switching capabilities. Based on the dynamic IP/MPLS protocol and key technologies, the ip ran is a solution t

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

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

and services, network operating systems (OSS), and black-box implementations of hardware. In traditional networks, data planes and control planes are implemented through routers and switch firmware. These two planes coordinate work, the data plane is responsible for forwarding the data flow, through some protocols (including Vxlan, GRE) to handle multiple conversations, connect and manage remote clients. The control plane is responsible for processin

not general enterprises. The last group of people thought that the news only represented a very large scale phenomenon, not a big trend. They don't really put too much attention into the community until they see a large scale of applications. This type of people is more traditional, which means that existing suppliers will maintain a business for a long time. Conclusion What is my opinion?

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

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
