• R7500 use of bandwidth by the device and the application does not appear anything.

  Hi, I am currently using a v1 R7500 and since Thursday, I have a problem with the use of bandwidth per device with 0Mbps of traffic for each device.

  

  When I inspect the traffic on the page with chrome I get an infinite number of error at the rate of 1/s.

  

  Does anyone know a fix?

  Factory reset and reflash the firmware

• How to reduce the use of bandwidth LAN?

  I want to design a relay system using two USRP of NI USRP 2922 with sample rates even as LTE standard. But there is limitation in the use of bandwidth of 1 Gbps LAN.

  I don't think you should achieve the full rate on a USRP without a link dedicated to the PC.  The protocol used is UDP between USPR and PC which can be disruped by the latency of the network and cause packets to arrive out of order or get lost.  You should also assume that, due to the effects of edge filter only 80% of the specified bandwidth is usable.  (20 MHz of bandwdith requires a rate of IQ of 25. MECH / s)  It takes a fast PC with a very high quality (we use intel) NIC to get there.  But you will need to use the driver for the NIC card manufactuer and maximize the RX and TX buffers.  So far, I realized only on desktop computers and mobile no.  I also would assume the package of 20% load, so on a 1 Gbps link, I would not expect to exceed the 800 MB/s.

  25 MS/s x (16 bit 16 bit I + q) = 800 MB/s

  You can also, in the pilot, 8-bit mode which will halve your dynamic range, but also the data rate.

  For a system like yours, you can consider to put a PC next to each usrp and install 2 network cards in each PC.  You will add the latency, but the additional computer will give you buffer against congestion and network problems.  In addition, relay is not a 'constant' streaming activity... only the RX is constant.  For TX, you can use the approach of gusts of transmission.

• Limit the use of bandwidth per device?

  My father-in-law uses a program that didn't live follow tickers in different stock markets in the world. It takes up bandwidth on our network and does not care if he does or not. It's a real pain, because he will not change his program or get his own connection.

  Is there a method to limit the speed/bandwidth of each system?

  Why not put a QoS rule in place, for this particular device (using IP address or MAC address) and give priority to "low"?

  Allowing him the course "low activity" of others to get optimum bandwidth, and when others are on the same router / network, it will give priority to traffic, via its connection.

  It seems to work at home, where users of League of Legends and Skype (I know who they are :-)) have a low priority, and my work VPN connections have a higher priority)

• Hot to draw what is using internet bandwidth on new Acer V5

  Re: V5-131-2629, Windows 7, nine

  I would like to know what program or process is send and receive megabytes of data on my 3 G connection. My Acer ZG5 (XP) used about 2K bytes of data to get connected to the internet so no more until I loaded web pages. The new Acer V5 immediately sends and receives several megabytes of data to the log on. Also at the time when it is connected but not loading of web pages it will start sending and receiving a lot of MB of data until I log out. It is a problem with my very limited 3G service.

  I use the same Virgin Mobile MC60 (Novatel) USB modem on both computers. It does the same thing with Firefox, Internet Explorer, and Chrome.

  My conclusion is there is a lot of 'services' and also some items in the menu that are send and receive data whenever an internet connection to start is detected, even on a brand new with a single software OEM computer. Together they secretly out a huge amount of bandwidth. This really should make known to the user of Windows 7. I disabled about 20 different services start menu items to take care of this and my sluggish internet connection is much better.

• Use of bandwidth IPSEC 3Des

  I have 2mbps link we want to enable ipsec 3des on the same if say my 50% of the binding is used at the point and if activate ipsec 3des what bandwidth utilzed after having activated the ipsec.

  3662 w/AIM-VPN/HPII - 2mbps link - 3662 w/AIM-VPN/HPII

  The answer depends on whether you use 3des to encrypt new traffic currently does not flow on your existing binding, such as the establishment of a new remote site location. If the encrypted traffic is new, it's something extra which does not affect the flow of the current, then you will need to analyze the structure of traffic.

  I think that IPsec will add about 50 to 80 bytes for each package, depending on whether it is ah will be used as well as the esp, if WILL be used, and if tunnel mode (new ip headers) must be used too. (Add 24 bytes for AH, 24 bytes for the GRE and 20 bytes for new IP header).

  If the IPSec vpn will be used only for existing traffic, instead of new flows, the util link should not increase that much. It is time CPU more bandwidth, and I see that you unloading encrypt cards.

  Let me know if you need anything that anyone else.

• use of bandwidth network

  Hi, I use the Java API of Sigar to get CPU load and free memory (in percentages) and there is also a lot of good examples on the sources provided showing this kind of functionality. However, how can I use Sigar to get a similar percentage for the use of the network? It doesn't seem to be an example of how you could get this information. I understand that the metric is not very well defined, but I was thinking something in the sense of the amount of traffic entering and leaving as a percentage of the bandwidth of the Network Interface Card. Windows 7 provides at least one such metric in the Manager of tasks, tab 'Networking' and I was trying to get something similar using Java and Sigar.

  You should take a look at these Java API class:

  NetInterfaceStat

  You can get the values:

  RxBytes

  TxBytes

  Speed

  For a list of the detected interfaces a Sigar object has a method called:

  getNetInterfaceList.

  This allows to detect return of the ETH network, wifi and loop devices. You will need the name of the specific interface OS when getting a reference to the NetInterfaceStat object.

  The tricky part with the use of the network is the implementation of the platform of SIGAR with each operating system. If my memory is correct that Linux has a NOT_IMPLEMENTED indicator set for the interface attribute speed (done in the OS interface layer in the SIGAR C code). I did some experiments under Linux to get this value and its root very intertwind with level permissions to query the hardware. For Windows, you should be fine. For Linux have a way to pass a value configured in your application.

  Good luck.

• API for computer processor Cycles virtual, use of the RAM, use of bandwidth and disk space

  Hello

  Since I'm pretty new to VM Ware, can someone suggest me how to extract the following by a c# application:

  • VM real-time CPU usage

  • VM use of memory in real time

  • VM bandwidth for a session

  • VM allocated disk space and used disk space

  • VM e/s disk operations

  Any help on any of the topics mentioned above is appreciated.

  Also, please let me know the appropriate community if this isn't the appropriate community to write this query.

  Thanks and greetings

  In terms of network and IO usage, it is available, but I don't know where.

  Good starting point is to understand the VI API object model (useful tips, you can ignore the specificities of Perl): http://www.vmware.com/support/developer/viperltoolkit/doc/perl_toolkit_appliance_idx.html

  By poking around the QAnywhere VI guide is also a great place to learn where to find certain things: http://www.vmware.com/support/developer/vc-sdk/visdk25pubs/ReferenceGuide/index.html as well as looking at the CROWD on ESXi/ESX/vCenter is another great place too (http://hostname/mob).

• Use a locally swc file to optimize the use of bandwidth for an LMS

  Hello.

  I have an LMS (learning management system), which also uses elements of the virtual world as avatars, games with great graphics etc...

  Bandwidth here in Spain is bad to say the least. Games like world of warcraft ship a CD to put heavy graphics on your local hard drive. It would be a great idea for our e-learning system. Is the best way to use a CFC which is impossible to decompile? It would save a lot of headaches.

  Well, what I'm trying to ask is how can I protect our graphics piracy if installed on the pc local users.

  Thank you in advance.

  You may simply want DRM. Here are some links to check out:

  By the way, the images are data binary just so you can encrypt them with something fast like RC4, use a library, for example:

  https://code.Google.com/p/As3Crypto/

  Ultimately if someone REALLY wants your content, there is no 100% average hackproof. I would implement a reasonable attempt at DRM or encryption, but really measure against the performance hit you'll take to do, with the knowledge that you really cannot guarantee protection in any case.

• Windows updates uses my bandwidth / or Mbps? that is billed by my ISP?

  My updates of the window shows I have several updates that must be installed on my PC - if I leave updates, will be my bandwidth / or Mbps (that I pay my ISP for each month) being exhausted. Windows Updates screen shows some resemble 10.9 MB and so on which is a huge amount!

  Yes, WU downloads are counted by your ISP.

  No, there is no adjustment for the bandwidth that uses the device.

• 9 use of the bandwidth of Captivate

  Anyone know an easy way to track the use of bandwidth for Captivate courses, or is there a line course Director for how much bandwidth use? We are in an environment in which some areas have very limited bandwidth and cannot play our course, even without audio or video included.

  I am not interested in tips to reduce the size of classes, just some numbers bandwidth usage I can give network administrators. Thank you!

  Have you tried to download on SCORM cloud?

  I think they have performance statistics generated after the course has been viewed which could provide the base you are looking for.

  You should also consider the LMS you use will also have an impact on performance for your users.

  A user at each location could run a 'speed test' to check the upload and download bandwidth they know. This could also be useful to your network administrators to have a conversation with your service provider.

  Older hardware uses a different protocol and the later models of wi - fi security, so

  It may be that the unit is able to see the signal available but not able to use it or connect.

  In order to set up an AirPort Base Station wireless vintage separate from any modern

  wireless local area network is a way to use a less secure configuration wireless computer older

  and without compromising the latest systems which would share a reduced security wireless

  If you want to reduce the overall security of the system (using the old protocol WAP,

  WEP, etc.; drafters WPA2 +) and base stations can be more difficult if they

  also have more than one type of signal. Older computers use less bandwidth.

  At this point, I cannot possibly be a great help; short of reading thanks to my favorites

  old pages (and check if the pages still work online) reference to use the installation program.

  My setup wireless WPA2 but earlier use AirPort Express base; and also have older

  base station AirPort Extreme 54 k White orb on-site; but not currently enabled.

  To have an additional wireless hardware for use with vintage computers.

  Good luck in this case!

• Bell wireless Hub bandwidth/AppleTV/Extreme band

  Hello

  I have an AppleTV and I want to see a movie in WiFi from my MacBook Pro with Airplay. WiFi is provided by Bell connection Hub. Bandwidth down too quickly.

  Is it a good idea to buy an Airport Extreme to create a personal network? Is that the bandwidth will be free to see my movies?

  Kind regards.

  Just use wifi to transfer files... but video streaming is always bad... always... It is tempting to voodoo gods to destroy you.

  An airport extreme could help... for a while... until you look at something really interesting... essential to your survival... WiFi will then drop out and movie starts skipping, stopping, desynchronization sound... name you.

  Use ethernet... at least one of the connections... or take your MBP to the AppleTV and plug with ethernet... use a bolt of lightning for the card ethernet if your MBP missed out on the most important network port in existence.

  It's all local network... the original movie downloaded from internet will use the bandwidth you pay for... It plays on your local lan will not.

  I don't know a command that will show you this exact info. But there are some statistics you can get by using the following commands.

  # Displays the counters interfaces

  # show rmon statistics

  You can also check out some of this info in the web GUI under Statistics/RMON > Table views > use summary.

  Hope this helps some.
