RE: stds-80220-ch-models: Traffic modeling sub-group: Call for interested parties
Shankar and All,
An extensive work has been done on traffic models in relation to 3G standards. For example, 1xEV-DV evaluation methodology in 3GPP2 specifies detailed traffic models for HTTP, WAP, FTP, Real-time video and wireless Gaming applications.
I understand that new applications appear all the time and there may be applications that apply to mobile broadband wireless systems only. Therefore, we may need to work out the details for these new traffic types. For example, VoIP traffic was not specified in 1xEV-DV evaluation methodology because voice is, in general, carried over circuit switched dedicated channels in 3G systems.
I think if people are interested in first looking at the existing prior work, we may want to first look at the existing models specified in 1xEV-DV evaluation methodology. Note that the traffic characteristics change all the time and we may need to adapt the 1xEV-DV models if we decide to use them. For example, the statistics of web pages in web browsing application (and size and number of objects per page and the protocols used HTTP/1.1 vs. HTTP/1.0) keep on changing due to obvious reasons.
Regards,
Farooq

interested parties
Greetings,
To start off the discussion on traffic models,
let me ask for interested parties to please
send a short message to me (shankar@research.att.com)
or to this std-80220-ch-models e-mail reflector
(you will need to first subscribe by going to ..
http://grouper.ieee.org/groups/802/20/eSubscribe.htm#Archive_Access
There is also an e-mail archive on the above
site. The first message in the e-mail archive
from Mark Klerer titled "Archive Setup and
Contribution Allocation" identifies the
contributions to date that have some relevant content
on traffic models. Our discussions will take
that into account. So please take a look.
I would also like people to point out other
relevant documents e.g. 3G standards, 802 standards,
papers addressing the topic of standard traffic models.
I believe that there is little work in the
area of standard traffic models compared to, say,
standard channel models. It would be good to
find all the existing prior work.
I believe that the objective of this
subgroup is to produce a traffic model document
which specifies statistical models for
different user traffic types
(e.g. Web, FTP, email, VoIP etc.) that are
relevant to mobile broadband wireless systems.
These models will typically be used in
computer simulations.
