theory of SDN centralized control, which is controlled by VCFC (VCF Controller). It is the key to support virtualization, business Network programmability, with the following features:
It realizes the decoupling between the tenant logical network and the physical group network, and the separation of the control plane and the network forwarding plane.
Business resource pooling, which can be allocated, deployed according to tenant network
(Because the writing is really too good, so must be reproduced)This was the first in a series of blogs posts that details some of the inner workings of Kubernetes. If you're simply an operator or the user of Kubernetes you don't necessarily need to understand these details. But if you prefer depth-first learning and really want to understand the details of what things work, this is for you.This article assumes a working knowledge of Kubernetes. I ' m not going to define what Kubernetes are or th
SDN is the most popular technology concept nowadays. As the core component of the future network architecture, SDN controller is still evolving in the future. For enterprises, what functions and attributes do SDN controllers need to know in advance? The following are 10 functional standards that enterprises need to consider when selecting an
SDN promotes vro Technology Revolution
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, the router interfaces have changed from a wide variety of narrow-band interfaces, such as X

The SDN technology has been developing for several years, and the history of cloud computing is longer. The combination of the two is even more popular as a killer application of SDN in the past two years, some well-known consulting companies have come to the conclusion that
the set of guest access and wireless access will become a unified packet network. when the integrated Guest access network and the wireless network are unified, operators will have more urgent need to introduce SDN . the reasons are as follows:
SDN centralized control that enables end-to-end unified management and scheduling ;
SDN a big advantage i
TextView implements hybrid orchestration and textviewTextView
I. Introduction
Here we use the pre-defined Html-like labels in TextView to implement text-and-text hybrid orchestration.
Ii. Method
* 1. Set the html Tag text.
String html = "Html + = "Html + = "Html + = "Html + = "
* 2. Declare Html. fromHtml for the previous text so that TextView can be parsed as an html Tag.
TV _one.setText (Html. fromHtm

Lihua design orchestration simulation system is mainly based on MFC and OpenGL, and uses linked lists to implement a hierarchical particle system. The first time we designed and implemented a complete software system, we gained a lot. Of course, now I look back at this system and find that this system architecture is so poorly designed.
I. Requirement Analysis
1. Identify the fireworks discharge process.
2. Analyze the particle motion rule. Underst
Helm IntroductionDeploying container cloud Applications (container or microservices orchestration) in Kubernetes is a challenging task, Helm is to simplify the installation of a client tool for deploying container cloud applications in Kubernetes. Helm enables developers to define, install, and upgrade container cloud applications in Kubernetes. At the same time, the container cloud application can also be shared through helm.The overall architecture
We open the development environment and create a new projectNamed asContent isIn section, we use this H2.Add a p to it belowThis section can be copiedThe way this is organized is this display orchestration, we can go to our browser to see. Paste the code into the HTML5 Outline Analysis tool, and then change the encoding to GBK, otherwise there will be garbled.HTML5 Explicit Orchestration Introduction
The original default design will separate SDN separately, with a small title of "Sdn",The following changes can be achieved by the same arrangement of SDN and regular numbers, in alphabetical order.Defaultcontactlistadapter.java in the Configureselection () methodComment out the following statement for selection Is_sdn_contact + "/*** M:new Feature
Software-defined networks (software Defined Network, SDN), a new network innovation architecture of Emulex Network, is a way of realizing network virtualization, and its core technology openflow by separating the control surface of network equipment from the data plane. Thus, the flexible control of network traffic is realized, so that the network becomes more intelligent as a pipeline.Note: Network Function Virtualization Industry Alliance (Networks

For switches in an SDN network, the above exchange functions can be implemented using software or hardware based on the needs of the Use scenario. Software-implemented SDN switches are usually integrated with virtualized Hypervisor to support multi-tenant flexible networking and other services in cloud computing scenarios. The hardware-implemented switch can support networking Based on hardware devices and
