• Community Updates / Open Forum
• Question if anyone is doing sub-second polling to capture microbursts of traffic. Some responded that that's too often, a packet capture would be better. Other responded that they are polling a various intervals. Some said 5 min, 1 min, 15 seconds, but it all depends on if the hardware would handle it. Also the device counters update frequency will need to be adjusted.
• Multicast tools: some are using multicast beacon and some are using dbeacon. NYU mentioned IPv6 Beacons.

• Ken,
• Hope to see you shortly in the session.
During the Open Forum part of the hour, I'd like to ask whether or not there are any plans to include standardized testing of mobile wireless broadband. One of my colleagues in California is interested in this as we have up to know relied on the overoptimistic data submitted by local providers and would like to have a standard method to provide accurate measurements (actual data collected by the R&E community). It might help some of the rural or under-served areas that they connectivity is indeed less than represented.
I am attaching a summary of the work in this area by Professor Byun of CalState, Monterey Bay. If this is of interest to the group, there might be a follow on presentation at the upcoming Joint Techs Conference in Palo Alto, CA.
This is the summary and current status of our work:
================ Summary ================
This project aims to develop an integrated software tool
to measure the performance and coverage of mobile
wireless broadband data services in California.
The tool will be used to conduct vendor independent
measurements of wireless broadband in California and
record the results into a database.
Our tool’s testing items include TCP download/upload
speed, packet latency, UDP packet jitter and loss, network
type and network provider. The tool will also support
capabilities to test traffic shaping.
Initially, the tool will be used to measure the coverage
of 4 major service providers, such as Verizon, Sprint,
AT&T and T-Mobile in California.
Testing will be done on both Android devices and laptops.
The tool will eventually be available to the public
so that the users in California can do independent testing
on their wireless networks and upload their results to
a central database if they want.
The database will store all test results and can be used
to look up the coverage and bandwidth of each provider
at any given location.
================ Current Status ================
We will conduct our first field testing in the middle of May
at 1,200 locations throughout the California.
The tool is under beta-testing stage but will improve the user
interface after the first field testing.
We maintain two servers to measure the performance
at the moment.
============================================
If you need more information on our project, please let me know.
I hope that we have a chance to meet you and talk about
the project in the near future.
