You need to save the personal information and salary records of each employee so that you can know who paid the salary and when, and you must summarize these records so that you can report the income to the tax authority. You also need to understand what your company hires and what you make for each job. 　　 ■ You are a teacher and need to know the credits and attendance information. Each time you take a test or test, you must record the credits of the students. It is easy to write yo

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

is especially important. 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. VPCN

provide and OpenFlow protocol, topology and other related information query and configuration, the results of the query returned to the browser in JSON format, and the configuration will call related functions of the relevant modules, you can simply see the code to get the switch in the SDN network. 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. Microsoft simulates the entire Azure network to prevent interruptions. In the case of ultra-large scale, copying an enterprise network is only for testing, 9. How cloud co

As an important technology of network virtualization, VXLAN has received much attention. How does this protocol work? How can we achieve SDN network through separation of data and control layer? How to deploy it? This blog will introduce you in detail... I. Why Vxlan? 1. limits on the number of VLANs 4096 VLANs far cannot meet the needs of large-scale cloud computing data centers 2. Restrictions on physical network infrastructure IP subnet-based Regi

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. However, there are few open-source software-based routers or routing solutions. To this end, this article introduces three s

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

What's white box switching and white box switches?White box switches refers to the ability to use ' generic, ' off-the-shelf switching (or white box switching) and routing ha Rdware, in the forwarding plane of a software-defined network (SDN). White box switches is really just that– ' blank ' standard hardware. They represent the foundational element of the commodity networking ecosystem required to enable organizations to pick an
