Lightbulb Traffic watcher

When we download (at the same time) 10-20 files with JD, we can not surf comfortable, because JD use our bandwith. That is normal. But if JD can watch out bandwith, when we want to use the internet independed from JD (for example from firefox or chrome, system updater...), JD will slow down automatically. So we can use the bandwith thinking like JD is not download anything background. This feature will use a little bit from performans but for quick computers is very useful. Thats why it must be add as extensions ( http://board.jdownloader.org/showthread.php?t=28929 ).

Now you can tell me that i can limit the speed limit from settings of JD, but this is not a comfortable solution. Because i never use the computer at work all the time. I always sit and leave the computer every half hour. Maybe every ten minutes. I don't know. I don't wanna even know. So if JD has a feature to look the bandwith automatically, we don't need to set everytime a limit when we use firefox, and we set again as unlimited when we leave the computer everytime.

Thank you!

jD can't watch traffic from and to other applications and ports on your computer or any other computers in your local network. You can use a sophisticated traffic shaper or a bandwidth limiter for this purpose.

What you're asking usually is already built into every OS's network management. In normal conditions (no viruses nor badly configured firewalls) an OS will never allow one application to suffocate another one bandwidth wise. In conditions where an application needs a lot of bandwidth (video streaming, on-line gaming or cellular communication for instance), QoS is put into action. For Windoze, see "Windows XP Quality of Service (QoS) enhancements and behavior" ("http://support.microsoft.com/kb/316666").

What you can do additionally is increase your browser's process priority a little. In Windoze you can set its priority to 'AboveNormal'. It's possible that your jD is eating too much CPU cycles when downloading 20 files simultaneously and your browser is suffocated by a lack of CPU cycles.

OK. I understand what you mean but even every OS has his network managemnt we can not surf comfortable anyway when we download too many files at the same time.

I know any software can not listen all other ports (without root permissions) but must be a way to watch if the bandwith is using or not. Maybe we can not listen the ports but maybe we can ask to OS if there are many request to use network or not. Or maybe JD can check everytime the list here : **External links are only visible to Support Staff****External links are only visible to Support Staff** and if there are other process which use the network, JD will slow down (for example) 15 kb per second than if the other process start to use the free bandwith, JD will slow down again 20 kb per second... Or something like this... Why not ?

Free download manager has a similar feature: **External links are only visible to Support Staff****External links are only visible to Support Staff** But it does need support every browser on every OS speccially. We need a general solution.

Thank you again!

You can set a limit to the number of files jD can download at any time with the Max.Dls. option. You can also set a maximum Speed or Pause jD in situations where you need all the bandwidth for another application. Dynamic and automated traffic shaping shouldn't become functionality of jD.

FDM only takes into account the browser's activities and it doesn't take into account its real traffic. It decreases the Traffic Usage Mode or selects the Light mode when it detects browser activity. FDM only runs on Windoze, but jD is running on all platforms that support the JRE 1.5/6.

I'm usually using at least 5 applications that need to download/upload data to the Internet. If jD and all the other applications would have to manage their traffic based on the traffic of the other applications I would be running 5 traffic shapers plus the one of my OS. This would lead to a traffic management quagmire.

If your OS can't cope with the traffic or has a bad build-in traffic manager, a traffic shaping program might be useful. These tools are specialised in what you want.

remi sorry but i can not understand why you think that this feature should be managed by OS. I use 2 linux OS and windows 7. But i can never surf comfortable when i download too many files with JD. This is not JDs fault thats why it must be a feature (at least as an extension who thinks that his OS is enough for network management ) for JD.

I don't know what FDM does but it is a solution which is not a solution as you sad (also as i told you) for JD. Anyway but we also need to find a solution for that. Every feature has it's advantages and disadvantages but every user selects features which use.

On my first message i explain why Max.Dls. and other all feature are not solution for me.(NOT JUST FOR ME) Maybe other users now are not thinking about this feature but all other friends i know can not surf comfortable on internet (when they download) i can see it when i visit them

You told me that you have 5 applications at the same which use network. OK but this is not a problem for management. Because JD will never stop. I told you that JD always will slow down 15-20 kb per second but also this decrease will have a limit too. So it just will left a little bit free space. just that. Nothing else. (This limit also should set by user).

With the free space which lefted by JD, we will be able to surf comfortable. I don't want to set unlimited or limit the speed of JD every time sit and left the computer.

I recommend letting your friends read this thread. Maybe they understand the issues better.

My experience is that my Windows XP, but I've seen it on earlier versions of Windoze as well, takes into account all traffic nicely. I can see that as well with my upload because my upload bandwidth is more limited. Sometimes I'm uploading files, my BitTorrent client is still running and one of my cloud backup applications starts uploading.

This clearly proves that my Windoze XP is able to manage all 3 upload streams dynamically and automatically. I don't need to interfere. On top of that my OS also manages the small upload protocol overhead of jD and other download programs I'm using simultaneously.

I've an old computer with a small memory. My browser's process priority is set higher than that of jD.

Maybe your problem is your browser and not jD. I use Opera on all my machines, including an old W95 machine. It's always been fast. I know that some browsers like IE are extremely slow, because I sometimes need to use them on machines that I don't own.

Another cause of your problems might be malware or a botnet. At the moment the TDL-4 botnet 'owns' over 4.5 million computers and the number is steadily increasing.

If you've such problems with your operating systems, why do you never comment on my suggestion to use an specialised traffic shaping program? Do you understand the reasons why those programs exist? Do you understand their functionality?

If you've to manage several computers and applications simultaneously and want to set guaranteed traffic rates or traffic priorities you might be interested in gateway software/hardware or router based solutions.

Have a look at the requirements tracking database and you'll understand why a request of an anonymous customer like you won't be taken very seriously or be implemented soon. More urgent requirements like for instance multiple proxy support and file renaming are already waiting for several years.

remi I understand exactly what you mean. You can surf on web with Opera on Windows XP. But who knows my operation system or my browser or other softwares that I use? Jdownloader works on Java which is maded to work cross platform.

You told me you can surf on web. And also you told me Windows and other OS have their conttollers about this issu. But i don't mind if they have or not. Because i can't surf comfortable. not just me i can see my friends too. Which some of my friends and I use linux distros many times which whey don't have virus or something (at least now).

You told me to go for other solutions ( like traffic controller softwares or...) but do you really think that i need install or configure my system JUST for this thing? (which is very difficult to control the network as you say for an end-user. On linux even we can find any program about anything... anyway...)

I have many times look for request for JD. Also I many times give my days-week to help about JD code. But don't forget JD is a GPL program and here there is no anonymous or known-user. Some open source softwares let the users to write even they don't have any account. And they care about they requests if they are logical. They don't look if the writer has account or not.

I understand that there are many important requests like multi-proxy, but i never told you set my request urgent or even normal-level! But if it is logical set it for far-away feature but you cant tell me there are many request and you are an anonymous ! We talk if the request is logical or not ? At this point you don't need to write that message. But i thank you again because you had write me at least answers...

I wish the other developers will write here about their ideas.

Thank you!

In this domain there are more approaches and solutions for Linux distros than there are for Windoze.

Try "**External links are only visible to Support Staff** if you don't find anything with the search engine you usually use.

Here are some resources on the subject :-

- CTShaper ("**External links are only visible to Support Staff**)

- Shape your traffic with trickle ("**External links are only visible to Support Staff**)

- Traffic shaping with Linux ("**External links are only visible to Support Staff** and "**External links are only visible to Support Staff**)

- Traffic Control with Linux Command Line tool, "tc" ("**External links are only visible to Support Staff**)

These are but a few examples of approaches and tools for Linux. If you need solutions or approaches for the Windoze platform, I can look them up for you as well.

I have no problem with your anonymity and I appreciate all suggestions and contributions made by these anonymous people, but identifiable customers usually earn more respect if they keep posting and contributing to the project.

Note that I don't decide about whether someone is going to program what you require. I can only discuss about the usefulness and feasibility of a bandwidth controller for an individual application like jD. I've tried to explain that such an approach isn't useful and hardly feasible. If you still don't understand these issues, I can only recommend reading more about the subjects I failed to explain to you.
