Is anyone familiar with traffic models can be used to size trunk groups for data network? I know that, Erlang B, Extended Alternate Routing Trunk (EART) , and Neal-Wilkinson are only applicable to Voice network.
Well the think you need to find out is what is the data activity factor, plus the downlink has a higher data capacity.
Usually the the data flow is assemtric (for normal users) higher downlink, in our network we used .75 data factor to the channel capacity on the forward link and .25 for the uplink,
you also need to see what kind of delay the system can hold.
regards
KHIs there an Erlang table or formula
for data traffic, in order to justefay the requiered trunks.
And also I would like to Know how to dimention or plan the ADSL network, what assumbtions should be concedered?
May thanks,Hello:
I want to receve the articles.
I would like to recieve many information about traffic data,specially from VoIP.
i start working on VoIP blocking ProbabilityI would like to recieve many information about traffic data,specially from VoIP.
i start working on VoIP blocking ProbabilityHi,
I´m working in my proyect in my university.
I need how to estimate the bandwitdh of the backbone of a network for voice, data and video. Here you give a lot of information about to calculate the trunks for voice, even video. But how can I estimate the bandwidth for data? Do you have any example? There are usual ratios for typical data aplications?thanks,
email: perenquen@hotmail.comMaybe Erlang C model can help to calculate how busy and Average Hold Time (AHT)
1. Try to get how many bytes/packets go thru incoming/outgoing.
2. Bandwidth available e.g. 128Kbps/64Kbps
3. Period time by hour
4. Calculate per hour – Erlang unit
5. Response time is AHTI’m also need feedback from all of you!
Hello and many thanks Nasir.
I need to estimate how much bandwith i have to install in my network. I have an idea about what kind of aplications it will run.
There are some usual values for typical aplications?
Do you know where can i find an example using erlang C model for data networks.
thanks,
I need help on how to calculate the bandwith required in CDMA network using IS-95A standard.

For those wanting to know how to do converged network traffic engineering, the above Cisco website site .pdf files should be able to assist you in that endeavor.

Here is another article on traffic analysis at Cisco. 🙂
http://www.cisco.com/univercd/cc/td/doc/cisintwk/intsolns/voipsol/ta_isd.pdfHello! I´m doing my proyect at the Seville University and I would be very grateful
if someone could send or explain me how to do a model for a mix of video, data and
voice over ATM.
It can be very interesting that the voice would be over IP= VoIP over ATM
If someone could send me an article or a web side in which I find something you´ll help me a lot
Thanks very much. MJesus
E-mail: martalopez18@supercable.esI need help to find out if any mothod available to block VOIP from ISP.
