floodlight controller

floodlight Controller re-write WebUI in PHPWe all know that the webui of floodlight itself is localhost/ui/index.html1. I tried to use my Linux environment to rack another server to provide PHP environment. You can refer to one of my other articles. about how to structure lamp.2.Proxy we set up a server on the host, and the backend command proxy is responsible fo

Platform Environment Description:Cpu:Intel Core 2 Duo T6570Mem:4.00GBOs :Ubuntu 14.041.FloodlightFloodlight is a relatively mature SDN controller implementation, in which the opendaylight Project also uses many of its implementation methods, the official website: http://www.projectfloodlight.org/floodlight/. in this paper, we use it as a controller, using virtual

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

We know that in the Netty architecture, a serverbootstrap used to generate a channel on the server side requires a channelpipelinefactory type of reference to serve the channel that establishes the connection, The pipeline processes requests from a client. So the openflowpipelinefactory here is floodlight to create the channelpipeline for the OpenFlow switch that establishes the connection.1. Idlestatehandler a idlestateevent event when the channel do

vim text operation instructions. When you write a script, don't forget to generate the executable file.chmod +x fattree.pyNote: If your script contains Chinese, it may be an error.For some reason, I didn't use screen mn ... Of the operation, but directly sudo itAnd in the execution of the script can not be connected to the controller, or connected to the controller after the Pingall is still not connected

1. In main, first load the module, start the rest service, and then build an instance that implements the Ifloodlightproviderservice interface (that is, the controller) and execute it; 2. Next enter the controller's run () method, at which time all the environment initialization work is complete. Build a TCP server based on Netty, the most important is the setup of Pipelining factory openflowpipelinefactory, Inside is

An SDN controller based on the OpenFlow protocol written in the Java language.The basic architecture, like webserver, has an underlying module that maintains the switch connection information, and when a switch is connected to the controller, Floodlight saves the connection to the connection pool and communicates with the switch by NIO.The

BLOOM.Here to introduce the implementation of the principle of bloom, in fact, it is relatively simple, first we need to set a luminance threshold we want to shine, first time processing, We need to filter the original scene, all pixels smaller than this threshold is filtered out, all pixels greater than the value left, so, We get a map that contains only the part that needs to be flooded, the rest is black, and the floodlight is produced by the diff

Question link ~~> Question recognition:At the end of the competition, it was a little painful, and the coordinates of the processing points were dizzy. So ~ After the game is fully awake, the AC will be connected. Solution: State compression DP, with only 20 points. If there are only different sequence problems during lamp arrangement, you can use state compression to recursion, but it is very troublesome to process the coordinates of the points, just clear your mind. State equation: DP [S | (1

Topic Link ~~>Mood: when the last bit of egg pain, processing points of the coordinate processing dizzy. So~ after the game sober a bit on AC.Problem Solving Ideas:State compression DP, with only 20 points. Let's say there are only a few sequential questions when arranging the lights. Fully able to use state compression to hand out, just to deal with the coordinates of the point when it is very troublesome, clear the idea of good.state equation: dp [S | (1 , in the case of State s and then add I

In the blog that introduces the four main objects, you can basically understand the process of program initiation:Main-->uiapplicationmain--> Create instances of UIApplication and app proxy appdelegate and set up proxy---> After the program starts, that is, after the splash screen is displayed, Appdelegate Create UIWindow (can be created automatically, or can be created manually)The question now is how to create a controller and set it as the root

By default, when an attribute cannot be found in the current scope, it will be searched in the parent scope. If it cannot be found until $ rootScope is
