WFQ with tail waiting

Dear friends,
I am not able to understand the relationship between the parameter QUEUE WAITING and Conversation value of WFQ.
I put this concept in my lab and concluded that "SHOW INTERFACE" command shows the tail parameters waiting in the QUEUE to EXIT and Conversation in parameter of the CONVERSATION.
I reduced the line waiting at its minimum and observed value packages were lost when flows are higher that the queue active. Then,

I reduced the conversion to its minimum and observed value packages were lost when flows are higher that the queue active
My understanding on this is tail waiting FIFO and WFQ is used the maximum value where an aggressive fall will happen in CDT either tail drop and DAVID will happen. Then, TAIL WAITING should be of higher value than the value of the Conversation.
Am I wrong? Please let me know your point of view if I am deviant
best regards & thanks in advance

Hello Sairam,

In this case, if i have different traffic flows, then ultimately all will be in class-default only.Thus, that much flows may be created inside class-default. Here what is the tool used to drop the excess flows as CDT does in typical WFQ??

There are several mechanisms here:

  • You can use the command limit the queue to set the maximum size of the queue by default together (which includes all lines of conversation if the WFQ is activated in the default queue)
  • You can use the DAVID on the default queue at disposal for proactive drops based on chance, until the queue is full

Note If you know that there is some delay can behave badly, or that require special treatment, you should not place in the default class but rather a special class for them and set the QoS provisions separately. The default queue should be considered as the best effort queue. The router will attempt to give a fair treatment to all streams, but with no special guarantees. If you want these guarantees so the flow is not supposed to be in the default queue.

Also note that even if there was no CDT, WFQ himself mechanism would work enough just because its principle is always at the service of the queue that has been most neglected (the so-called equity of max - min). That means CDT is a further improvement - if a packet arrives it's limit, but which can be managed to be sent back in time then fine - let it go at the expense of some other packages that would be the case, or so later sent. WFQ in implementation of Cisco, as active directly on an interface, is basically a closed solution and untweakable - you cannot change its basic behavior - so he's trying to be as smart as possible. The CDT in plain WFQ allows to ensure a package of priority higher who arrive later can still be queued at the expense other packets in different queues. You can do it in CBWFQ by the presence of a separate category for these packages, while WFQ, it was somehow cope alone. The CDT is a fine concept in plain WFQ with many implications. However, with the advent of CBWFQ, it is kind of superfluous.

NOTE: Initial topic (CDT > HQ) is still not clarified. please help, however efforts has been taken from my side to get the answer

Well, sometimes, the answer is simple is perhaps the closest to the truth - we try to find an answer sophisticated to a simple fact - the test of validation on the relationship between the TRC and HQ just is not implemented in IOS. Maybe the filmmakers forgot to do, maybe they wouldn't have to do as you can use it to effectively disable the CDT... There are several places in the IOS CLI where it is up to you to enter the healthy values of mind and IOS will not try to outsmart you and tell you that you are wrong. Maybe it's just one of these.

Best regards

  • x 305-q706 Stuck on splash screen where is says "Qosmio" with please wait...

    Hello

    recently purchased a Qosmio x 305-Q706. First time I booted up it gets to start with Qosmio screen displays with "please wait" down and hangs there forever. The only way I can get it to boot is to start cold and purée the key F12 for is loading from the startup screen, if I'm lucky, I can enter the option where you can choose which startup device, and if I manually chose the hard drive I can load windows.

    Someone at - he heard of this problem or how to fix it? I tried to change settings in the BIOS nothing. Re-iterate, it is stuck on the screen with Qosmio pslash, and if I press a key on the keyboard once it says "Please wait...". "he brings me just to the bios: (.)

    Any help would be appreciated.

    Hello

    This is a very stupid situation and I really don't understand why the laptop hangs at this level to start.
    Is somehow your Qosmio confused and cannot decide which device should be the first boot device.
    What is some external device connected to your Qosmio laptop?

    Maybe update the BIOS can help, but if you have all new laptop is not the solution. This is more recent laptop, and I presume that there latest version of the BIOS. So, if I were you I would contact either your dealer and ask for replacement or Toshiba service directly. This behavior is certainly not strange and laptop crashes somehow on the BIOS/POST (Power-On-Self-Test).

  • Legends of centered text with tails?

    Is it possible to create legends of centered text with tails?

    I know how to create a custom BMP and how to adjust the. FCM-file - but only for text captions with their corners, form tails or tailless. My client wants to pop up and infoboxes with tails centered windows and I´d you want to solve that with captive captions instead of make a PNG images for each of them...

    Otherwise I´ll create a caption of text without a tail and have to add all the tails as the images above

    For all those wondering about this thread, or who want a tail centric legends as well, it's here:

    1. That's what I had:
    2. The 'must have' were the following:
      -centered on the tail (always the same)
      -rounded corners
      -drop shadow and 1px border around the legend full
    3. So I created a legend of custom tailless text and an image for the tail:

      This way I can place the tail above the legend of text on each side it s necessary, align the two and finally to group all the items.

    Tips: The shadow of the text caption is defined in the properties, the drop shadow on the tail inside the image. This is why I made a legend squared to Captivate a copied in Photoshop ;-)

  • Animation of the arrows with "tails" more

    I am trying to simulate an arrow (more precisely, the tail of the arrow more more... not the head of the arrow itself) more and more.

    The arrow head would go a certain way and would effectively a trail behind it that's its tail.

    In the image as an attachment, there would be a white screen and then the arrow would be out of the bottom and follow an imaginary path, leaving the tail behind her.

    Having a hard time finding how to pull this off.https://img.skitch.com/20120321-m6krmay1h1wqrucntfjadauk7w.png

    It is not too difficult, but he needs a few layers.

    Start with a model of square pixels, which is higher that you actually need.  You will nest in your main computer later.  Do a solid and make the shape of 'body' of the arrow with the pen tool.  Forget arrowhead for a moment. Apply the edge effect to animate the curved line.

    Make arrowhead requires two solid: a solid square Palm to act as matte for the end of the race - stroke has a circular brush, and you will have to square OFF - and a solid with a mask of triangle, which is at arrowhead.  Copy the mask provide you in the body of the arrow in the position property of each solid.  Use the command from the East the long path for each, adjust anchor points and rotation if necessary, and then twist to adjust the timing of keyframes.

    It's an arrow made.  Repeat if necessary.

  • GlobalAutomatic with voidable wait interval

    Hello
    I would like to have a GlobalAutomatic activity that starts a process with a predefined interval, so I would use the vote by the Interval property. but I also want to change this interval dynamically, for example modifiyng a settings in company.

    If I create a company X parameter with a string value which is 5 m (5 minutes) that I can not use this company in the interval field to wait setting.

    Does anyone know how can I do this?

    Thank you

    The property of the poll to a Global Auto is be changed dynamically during execution.

    What you can do is rather to have a separate process running that has a Message activity wait (not a timer or you find yourself in the same situation you are in) with a transition Due to an automatic activity. There is a bit of "wiring" is necessary, but once you have it working you interval dyanamic functionality you're looking for. Here's where you can find and download a working example the steps listed below: http://www.4shared.com/file/229611869/5fbe296/DynamicallySetIntervalToCreate.html

    (Named "MessageWaitDyanamic" in the sample project) the Message property wait must be set to 'external '. The automatic activity (called "Wait for the time interval" in the example) have an unconditional transition to the waiting of Message and the Message activity wait activity would be a conditional transition set to "false", because you want the work item instance in this process of loop between the Message wait and automatic activity. You will use the automatic activity to create the work item instance in the other process (process called "Process to create Instance In" in the sample project) when regular transition fires.

    The reason why I did this way was because unlike the global auto and timer, you can dynamically set the interval of time used by a regular transition. In this process, note that there is an instance of time interval variable named "timeInterval. This variable is used in "Interval Expression" of the transition Due. If you decide to use a business setting to determine the interval setting, remember to make the parameter business a string and put it in 2d for 2 days, 2 m 2 M for 2 months 2 minutes, etc... If your setting of the company is called "TIME_TO_WAIT", then interval Expression of the transition of your due date would be

    Interval(TIME_TO_WAIT)

    There is a problem in which you must be aware of. Once the Message activity reached work item instance wait, she'll wait for the period during which has been defined in the parameter variable or commercial when it reaches the first activity to wait message (for example, 2 days). You can change the setting of the business in 3 days, but the work item instance still not use the parameter 3 days until the remainder of the initial term is up. The 3 days that setting you changed don't pick until the instance hits the automatic activity and back loops in the waiting Message activity.

    This is the case, I would say that you do what I did in the example. I added another activity wait Message named "dynamically change time ' which has its set of properties"Allows to interrrupt"(note the Lightning). Activity in the example named "dynamic change of time interval" allows an end user to dyanmically Global Interactive change time interval and then sends a notification to the current instance changing the time interval for the only instance running in the process of "process that creates Instances in Other Process." It interrupts the proceedings, sends the instance Message activity wait "dynamically change time", reset the time interval for the new interval, and then returns the instance to the activity of "MessageWaitDynamic" in the process.

  • Cannot create a new startup with my data disc

    Hi guys, here's the problem: when I try to create a new startup with my data disc, I can't boot from this drive.

    The startup progress bar takes forever and then I see a white circle with a line through it. ("Prohibited" / "Ghostbusters" sign.)

    In verbose mode, it hangs on "break pci: SDXC ' for a while, then it clears the screen and watch the Circle + line with 'still waiting on the root device' at the bottom left.

    I can't boot into single user mode. Quite simply, there is the same thing as verbose mode. Even in safe mode. So I have few options for debugging. I did a SMC reset, no change. Is there anything else I should try?

    Additional information:

    -I'm trying to start off a new SSD that I bought, currently in a USB 3.0 enclosure external. I know that all is well with the speaker because I started off of him several times in the past. I know that all is well with the reader, because I tried to do the same process with another drive and it doesn't work the same way.

    -J' cloned my current boot drive to the new drive with SuperDuper!, Carbon Copy Cloner and I also did a clean install of El Capitan using recovery mode. The new facility has worked well until I migrated my old data.

    - So there must be something in my data which are striated throughout this process. I don't know what it is maybe or how to track him down.

    Any thoughts are appreciated!

  • Problems starting with the Satellite C870D - 11 X

    I have a Satellite C870D - 11 X 8.1 Windows running.

Finally, he moves to a blue screen saying that your computer needs repair "a required device cannot be accessed 0000185 0xc error code.

    Unfortunately, I don't have a recovery disk to try this option. I'm looking at a hard drive failure? I hear a feint clicking of the HD as if hunting for something.

    If I buy a disc is it likely that I will be able to reinstall using this media?
    Thanks a lot for your suggestions.

    At first, I must say that you have made a mistake after that you bought your laptop you didn t create disk recovery or the so-called recovery media with the original version of Windows 8 that you got with your machine.
    I really do not understand why so many people make this mistake and do not create bootable recovery media installation backup image recovery.

    In any case, on this path virtual that is not easy to say what the problem is here and, in my opinion, the better you can do is to back up all your important data and install original recovery image. After doing this, you can test the functionality with the factory settings.

    A few days ago, I found interesting options paper of recovery limited after update to Win8.1 - http://aps2.toshiba-tro.de/kb0/TSB4403L30001R01.htm
    You should try to install the HARD drive recovery original anyway. How is it that you can read on http://aps2.toshiba-tro.de/kb0/TSB2A03ES0000R01.htm or http://aps2.toshiba-tro.de/kb0/HTD1303440001R02.htm (Win8/8.1).
    Order recovery media can be your last step.

  • Bad step Wait() runtime

    Hello

    I have a very strange problem. We still use TestStand 3.1 for our tests of production and we are currently running TestStand 12 different test stations.

    I just got a new nootbook that I use for the development of tests, but now I have a very strange problem. When I run the tests with a Wait step (execution)

    time for this step takes 3 - 5 times longer than the number of seconds that I put in the expression. For example if I do a sequence containing a single

    Wait (5) this should take about 5 seconds to perform the step but it takes 15 to 25 seconds to run! And to make it more strange, the execution time report

    Watch 5.1 seconds? All the other steps I run runs at a normal speed, my own or types of standard step (at least what I've discovered so far).

    I had installed on my laptop, older without problems TestStand. I have tested both on XP with and without SP3, but no luck!

    Now I must find out if TestStand or my laptop that is causing this problem, it is not easy to explain this problem for people a HP. What clock makes the

    Wait for the use of the service and could I do a sequence of debugging that could give me more information about my problem.

    I have now reinstalled my phone 3 times and reinstalled TestStand 6 times so I do desperate to me, anyone could give me some ideas what could cause this problem.

    Concerning

    Anders

    Although this talk article of a bug related to an AMD processor and your machine has a processor intel CPU, maybe the solution it might still work. I think what the computer to use a different hardware clock by adding the indicator/usepmtimer to the boot.ini file.

    http://support.Microsoft.com/kb/895980

    This links makes it sound like the problem or a similar problem can also occur with intel hyperthreading or enhanced speed step systems and circumvention of boot.ini even use/usepmtimer is one of the suggested options.

    http://support.Microsoft.com/kb/835730

    I don't know how he is sure to try this workaround but I understand if you do not prefer. I would definitely support upward everything you have is important before you try the boot.ini changes incase she ends up making the machine unbootable. If you do not end up try this workaround it please let us know how it goes.

  • Wait until the next millisecond several question

    I seem to have a problem with the wait until the next millisecond VI. I put it to expect from 1000ms and I inside a loop that makes a bunch of stuff, yet my cards in the loop updates about 50 times every 60 seconds. I thought that maybe, it took too long to run everything in the loop, so he "missed" multiple next MS, but if that were the case it could be updated every 2 seconds. It wouldn't make sense not multiple integer.

    So my code is a great sorta, if he is the obvious places I should look and see, in what concerns, why what is happening in a general sense and not specific to my program, I could try that first.

    Thank you!

    Your loop can go to the next iteration until all structures of the event have expired or been triggered by an event AND wait the 1000ms has elapsed.

    It is difficult to solve the problems, you might want to rearchitect the code a little first. It seems that all the structures of the event are triggerend by the same event. You cannot combine all code into one? Use a structure of single event, not the event structures N!

    Keep the pattern of a single screen. Get rid of all the structures of these unnecessary sequences.

    Eliminate everything that the duplication of code. Why have a huge identical set of nodes of property in each case a case structure? Are not nodes of property after the structure of the case? Write to the properties when the value changes and not with each iteration of the loop.

    Use local variables instead of nodes in value property.

    Can you measure the loop with more conventional means to get a value of exact time loop?

  • Strange problem with my FPGA Code

    Hello

    I am running the following program, but I am facing a strange problem:
    -I can read all analog and digital input and write on the outputs analog (I measure the tension that I write on the map of the AO)

    - But the valves I have connected to the analog output, flashes a red light (which, according to the data, sheet means the electrical signal I send to them via the module AO is incorrect)

    -However, if I delete the ms and RMS block and do not make any average samples, but let all even (still two loops and two of the nodes separated from FPGA to e/s), the valves are operational and flash not a red light.

    I have a cRIO with four modules:
    -1. The (Mod1) AO cards
    -2. Map of HAVE it (2)
    -3. DI/O card (Mod 3)
    -4. Map to HAVE secondary (Mod4)

    I currently have two loops on the fpga all-in:
    -' Hand Loop (ML)': reads and writes I/O cards 1-3, with an expectation to 300us
    -'Top pressure sensors Loop (PACKAGE)' reads two HAVE the fourth module (Mod4), with no waiting

    These two loops are indicated in "fpga - part 1.png" and "fpga - part 2.png".

    The settings for the ms and RMS measures VI, as well as the façade are indicated in "fpga - part 3.png".

    The second loop uses 12002 ticks to run, the first loop use 160 ticks to run

    Previously, I had a similar problem which was fixed by setting the initial values indicated on the front cover for the analog output to the valves.

    Currently, I have not any target VI race and I'm only using fpga VI

    Any suggestions? Thank you!
