SDN is undoubtedly the most popular keyword in the network field in 2013, but more is the concept hype. Many vendors have published their own SDN products and strategies, however, only a few released products are commercially available. In 2014, the SDN technology will make a great leap, and more products will be deployed and ready. By interviewing several industry analysts and discussing the SDN market forecast for 2014, we generally think that SDN will stride forward. 1. More

In Interop 2012 in Las Vegas, I asked HP two questions: what is the current situation of HP OpenFlow and software-defined network strategy? What is the progress of the HP 12500 Series Data Center rack switch? Fortunately, at the end of the meeting, I had the opportunity to communicate with Mike Nielsen, HP Network Solution sales director, who gave me some information. Here is what I know: HP 12500 is planned to be updated early next year You may have

How can I change the hardware and software to successfully deploy OpenFlow? Are there any interoperability considerations? Stephen J. Bigelow:OpenFlow deployment requires OpenFlow-compliant switches, such as HP ProCurve or IBM G8264, and OpenFlow controllers, such as the Big Network Controller from Big Switch Networks. NEC also provides PF1000 vswitches for Hype

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 forwarded according to the flow table. Run on the t

Many people do not understand the difference between openflow and Sdn. It is not surprising that these two technologies are closely related, so many people have such doubts. However, they are not interchangeable. Openflow is a protocol that uses a process like an API (Application Programming Interface) to set up a network switch. SDN is a term used to describe the highly automated configuration of network s

SDN (Software Defined Networking) SDN is not equal to OpenFlow, its relationship is similar to the Internet is not equal to IP protocol, PSTN is not equal to 7th signaling, IMS does not equal to the sip,web system is not equal to the HTTP protocol. OpenFlow is only the SDN controller control forwarding Surface Equipment protocol, the controller's own architecture, network topology algorithm, operating envir

This paper focuses on the instruction set of the OpenFlow switch specification, which profoundly affects the processing behavior of the packet in switch, starting from the following sections.1, instructionsEach flow entry contains a series of instructions that are executed on a packet that successfully matches the flow entry, resulting in changes to the header information, Action The update of set or change the processing behavior of pipeline processi

Software Definition X has become increasingly popular. Software is eating the world. The same is true for Software Defined networks. Both in the industrial and academic fields will be a great revolution. They are all following the direction of this industry, looking for their own research points, and paying attention to the development of standardization. Various controllers and prototype systems have emerged one after another. Some of them are SDN debug and security. In short, they make the eco

Openflow-enaling innvation in Campus Networks Problems occurred Background Networks has become part of the critical infrastructureOf our businesses, homes and schools. Because of the huge installation base of equipment and protocols and the reluctance to use production flow to carry out experiments, network innovation has encountered a huge bottleneck, people think that the network has been rigid. There's no good way to tr

Recently see the POF code to see the headache, but fortunately is done, the rest is the idea of POF can be integrated into the code of the EPC, I also for the future 5G point of view is not? First of all, say what POF is.Introduction to POFThe full name of the POF (Protocol oblivious Forwarding) is the protocol is not aware of forwarding, Huawei proposed an improved forwarding method on the OpenFlow, this way do not need to know the protocol is what t

IPhone SDKDevelopment BasicsOpenFlowProgramming is a small part of this article. When the user interface needs to display images by PAGE, useOpenFlowFunction provided by the Library, the user interface image to be displayed is displayed on pages, making programming very quick. This Library provides the same visual effects as the OS X desktop Finder program, as shown in 3-46OpenFlowLibrary page by page for the image display program, you can press the screen to scroll around the display, double-cl

View B is loaded to view A, but the image of Openflow is not loaded. After debugging, the proxy of openflow is not loaded. -- "viewDidAppear method of View B is executed; Cause analysis: If a view cont

A long time not to blog, mainly because of laziness. Not much nonsense to say, now let this can only record their own learning process. What's the OpenFlow architecture, and what's good for me. If you don't understand, go ahead and see. Go directly to the topicMy platform: PC (Linux ubuntu 13.10), as well as the floodlight and Mininet mentioned in the title, also use the virtual machine software, I use VirtualBox. This architecture is as follows:The f

Recently has been learning Ryu controller, in the process of use, found the following aspects of the advantages: Ryu controller is written in Python language, in the understanding and speed is very fast; The Ryu controller's overall architecture is clear, In the future, I will organize an architectural article about the Ryu controller for your reference; The Ryu controller itself is a powerful network experimental platform that is very well compatible with OpenStack and is not very familiar to O

After debugging is OpenFlow the agent is not loaded. --The Viewdidappear method of B view is run;Analysis Reason:Suppose that a view included in a viewcontroller is added directly to a view. Just like this:[View1 AddSubView:viewController.view], so that our viewcontroller will n

Comparison between openflow and traditional vswitches in layer-2 Forwarding (1) L2 forwarding and Vlan traps Generally, after a string of bits in the physical layer are connected to the data link layer, frames are formed and verified. Only frames that pass the verification are forwarded. The concept of forwarding is MAC address-based forwarding for vswitches. The first layer-2 forwarding device is only based on MAC addresses and is used in LAN ), lat

Disadvantages:Only data streams

In this tutorial we is going to learn what to navigate programmatically (or imperatively) by using the Router API. We is going to learn how to use the function Navigatebyurl to navigate using a manually constructed string, but we are AL So-going to learn-trigger route navigation by using the Navigate API method, which takes an array or arguments and A Parameters object.We is going to learn how to do both absolute and relative route navigation using th
