Some people say that in the history of storage development, storage has long been more than just hardware, and software has a core position in storage. Some people think that software-hidden storage should be implemented, because software makes it difficult to manage storage, such softwar

The switch will ask the controller

Web page When the paragraph label p should be used in the paragraph there are many abuses of the newline label BR, p used to represent the paragraph is recognized. Based on the same logic, many tags should be used to define certain textual elements, such as references, abbreviations, and computer code. It should be remembered that although most browsers deal with these tags in different ways, it is important to remember that it is not about what the element looks like, but what it gives it. Init

Now you can take a sigh of relief. Software Defined Network (SDN) has become a reality, because Cisco has finally begun to "Embrace" it, which also marks the end of all kinds of "Cynicism. However, I cannot help but think of network virtualization because Cisco promotes the development of SDN. Network virtualization is different from SDN. It is completely differe

At the beginning of the VPCNG design, considering that the on-line process should be transparent to the user, without affecting the existing business situation, the smooth upgrade to the new architecture, so in the upgrade scheme design is also more complex.The entire upgrade process is split into four phases.Stage1 Routing Table Data MigrationThe most difficult thing to do in a smooth upgrade of a large distributed system is the seamless migration of control data.

The command to get switches is: http://ip:port/stats/switches, which first resolves the HTTP request (GET), and the required content (switches), and then

complexity, this is also the essence of TCP/IP, smart compression in the C jun and D Jun, as D Jun saw the content in the package is crying, laughing, dead, live, A Jun and B Jun is no matter. So where is the complexity? Complexity is added by future generations! It is not the core of TCP/IP. If we maintain the core of TCP/IP and connect the gully between June A and June B with A bridge like the San Francisco bridge, the efficiency will be greatly improved, therefore, QoS is the transmission ne

The story of the top ten data centers of the Year in 2017: data centers in 2017 The hybrid cloud partnership, large-scale public cloud collapse, the impact of cloud computing on the host hosting industry, and the design of ultra-large scale networks were one of the most popular stories in the data center industry in 2017. 10.

The vro market will double in the next year According to IHS Infonetics's latest series of reports, the global network market shows uneven performance in various fields. For example, the global data center network [note] device market revenue in first quarter of 2015 was only $2.6 billion, down fourth quarter of 2014 from 14%. However, in the first quarter of this year, the bare metal exchange market showed vitality, with port shipments increasing by 12% year on month. Cliff Grossner, data cent

Virtual Route Solution Overview: OpenContrail, Vyatta, RouteFlow (1) Preface -- about virtual Routing Can SDN or OpenFlow open up a new era for the routing market? The open-source software switch represented by OpenvSwitch has promoted the development of the SDN industry for a while.

languages, but mastering at least one, preferably two or three, languages can help you become more efficient and more popular.1.PythonWhenever you ask an expert, you can be sure that Python will be one of the two or three languages they first mentioned. Why? First, Python is easy to learn. In fact, if you're in college with programming classes, Python is probably the first language to learn. In addition, it is not necessary to compile, which makes debugging fast and easy. It is a common l
