Basic results

[regardtv]

Hello All,

I've been asked a few times on performance metrics of the iBurst system. While I'm not sure how this will compare to the rollout version I thought I'd give some quick feedback on ping times;packet loss and throughput.

ping times are directly related to signal quality. The higher the quality the better the ping times. This may also have to do with the error correction mechanisms of the gear.

Ping statistics for 196.31.17.162:
Packets: Sent = 14, Received = 14, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 69ms, Maximum = 139ms, Average = 75ms

I have seen ping times as low as 40 ms but I'm sure location is affecting things here.

By using large ping packets (1000 bytes) we get to see if packetloss is introduced when the link is actually being used :

Ping statistics for 196.31.17.162:
Packets: Sent = 25, Received = 25, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 159ms, Maximum = 560ms, Average = 208ms

Still looking good.


The SRT is my final test for this session:

11:53:08 (64.39 KB/s) - `DCPlusPlus-0.241.exe' saved [2044011/2044011]

Not quite the throughput they said I'd be capable of but with a varying signal strength between 50-70% I'm not unhappy.

Hope to get my latency graphing tools etc running on this baby soon (under linux)..

Here are some results from international tests. Admittedly, there is not much contention to speak of, at the moment.

I am connecting from about 10Km, with LOS, to Sandton base station.

Heck even if you only get half those speeds on commercial release it still looks like iBurst is gonna tear Sentech a new one! Thanks for the stats guys, keep em coming [:)]

We need more tests from you pilot testers,more results and performance tests,means more people will go over to Iburst and put Sentech out of business.

Come on be the one who started the great trek away from slowtech.



Google is so smart,I typed in Hellkom and guess what google said

Don`t you mean.....&lt;insert evil laugh&gt;
TELKOM!

I've been getting similar performance results for the last 6 weeks. The most fun was doing a live update of Windows and Office on my little Vaio laptop while driving down the M1 from Killarney to Sandton.
Pilot ends tomorrow (Friday 15th Oct) and iBurst switches to from 2.3 to 1.8.
Can't wait for the new towers to go up - see the maps at http://www.iburst.co.za/rollout.php
Hopefully I'll get better signal in the little shallow between Killarney and Corlett Drive.
The iBurst technology is GREAT. I just hope that in the commercial rollout the uuNet pipes from base stations are big enough. And of course Telkom own (most of) the tubing to the rest of the planet, so we still have hands on the throat...

[sihen]

I must agree with Anakin, I see great improvement on the 1.8 network

Of course, Sentech looked pretty good before the actual launch too.
