Figure 1: Low latency software defined networking control loop The articles SDN and delay and delay and stability describe the critical importance of low measurement delay in CONSTRUCTI Ng stable and effective controls. This article would examine the difference in measurement latency between SFlow and Netflow/ipfix and their relative Suitabi Lity for driving control decisions. Figure 2: sFlow and NetFlow agent architectures Figure 2 illustrates shows

One, openflow to solve what problem?1. First, a brief introduction to what is SDN, the traditional network is the computing route of each node itself, SDN is centralized control of the route. In a data center network, there is only one controller, the following can be connected to multiple switches. After the controller has calculated the route, the flow table is sent to the switch, and the switch is forwar

cloud providers cannot support the router hardware installed by users. In addition, there are potential sequential failover and overflow problems, because load balancing is not a normal property of VPN. The good news is that there are emerging solutions on the market that can help optimize the efficiency of VPN in the cloud environment. Use SDN to connect to cloud Resources An emerging method for connecting to cloud resources is to use software defin

In addition, there are a lot of other very small but very good products, Dropbox is one of them, it with the help of cloud computing, to provide synchronization of local files networked storage online applications, has been a huge development. In short, good products are hundreds, but turnip greens. Each their own, I can only tal

How do you calculate the user churn rate for your own startups? How many users are lost per month? That can't hold the key, because there are big customers and small customers. By the upward sales rate? That is biased,

the perspective of economics and enterprise management, we can also see why it works better. Scale can achieve "economic" From the perspective of economics, the profit can be calculated by deducting the cost of the operating income. The operating income is the income of all express deliveries, and the cost of each delivery service is equal: Cost of each delivery = (driver * salary) + (fuel * distance)/number of deliveries Therefore, in order to ensure profit, a courier company needs to charg

AJAX (Asynchronous JavaScript + XML. This is a development technology for creating interactive graphical user interfaces (GUI) and Web pages. It can automatically refresh data on network servers. With AJAX, programmers can develop host-based versions of desktop applications, such as file and photo Publishing. AJAX can provide users with similar user experience on PCs.

Start a business, but Internet practitioners will want to do something, or even do not want to do it, are embarrassed to say that they are doing the internet. This is a strange circle that everyone cannot escape. But why do we start a business? What do startups do? It seems that we do not have a good definition and awareness. In terms of small definition, entrepreneurship is a process of exploiting loopholes in a large system. In the form of small org

The Go language, known as the C language of the cloud era, makes a great tradeoff between software development efficiency and operational efficiency. This allows it to adapt to the rapid development of Internet applications, but also in high-concurrency, high-performance development scenarios in a duck to the top. That's why many internet companies, especially startups in the cloud computing world, choose the Go language as an important part of their

(last year Zuckerberg announced a new engineer slogan: "Fast-forward, stable architecture".) )When startups finally solve their revenue problems and become "mature," they can intelligently use the power of programming languages to manipulate the culture of corpor

In addition to Third-party data centers and private clouds, cloud computing startups face five big opportunities in the hybrid cloud sector. Today, anyone with credit cards can access the world's largest computers (such as Amazon's AWS Cloud), making today's corporate data centers look like mainframe systems in the old society: clumsy, complex, rigid, risky and costly to develop and operate. To keep up with cloud computing, companies have two realis
