Nstreme Advantages

Thu Apr 23, 2009 11:06 pm

I was looking at switching all my APs and customers over to Nstreme. Could someone let me know the advantages of Nstreme?

Thanks

If you're customers are going to be doing VoIP, gaming, etc I would strongly suggest against this move. When we started deploying our network we were only concerned with throughput so we went Nstreme for our backbone links and the performance was great but there are random latency spikes. We have since deployed additional links to compensate for this but broadcasting to the customers you don't have this benefit. For someone who plays any significant amount of online games it will be very frustrating to see 20-30ms or higher spikes randomly.

Tweak your framing settings and try the "new" wireless test package. These problems are gone now.

Agree with RK. The gaming latency with wireless-test dropped about 40ms~
And i'm able to run 40 clients on a single Radio AP without issues or bottlenecks.
+1 to nstreme :)

nstream is good, but sometime the hike in letancy could & may cause issue to low letancy needed stuffs.

What do you use as AP? RB600?

Are you ever READING this thread?
Medianet and I have clearly stated that there are NO latency problems with the latest versions of nstreme.

what is the best Framer Policy for AP
dynamic size?? none??


with BH links I run best fit without problems.

RK... Latest release 3.23 or latest wireless-test?

I dont use a framer policy and seems to work fine... what would be advantage of using one over not...

have you upgrade to wireless-test only AP or also any clients?
thanks

Only on AP, because upgrading all the clients is too long.
If happens i upgrade some clients and it improves a little the stability of it.

Framer policy aggregates smaller packets into larger frames. This can help to optimize the link, particularly if there are many
small packets. Framer policies do add extra CPU overhead. I believe starting at "best-fit" they get more cpu-intensive.

What clients do you use? I've tested with RB133c/3.23 as client. Speed drops
by 50%. CPU is too weak. I noticed Wireless card speeds going down. So AP radio
wastes Airtime when there is a client which cant handle packets fast enough.
So when there are old clients in a segment switching to Nstreme might slower
overall performance of this segment.

Tested with RB133c/2.9.51 is much better. 3.x on RB1xx seems to be no good idea.

I might agree with you Stefan, the 3.x on RB133 isn't really suitable, but lastests firmware upgrades (2.18-2.20) improved the CPU usage on 175Mhz processors. Of course the RB has to do only minimal work (Wireless+NAT) and no routing / hotspot.
It's still not the best choice as you already stated.
I decided to do the upgrade, i feel comfortable with it. Anyway i got only few RB112/133 still active in my network. The rest is RB411.

My test shows 6MBit on a 20MHz Channel. The AP-radio scaled tx-speed down. So one
slow RB1xx may slow down the whole nstreme segment to 6MBit.
To stay by this threads theme: Nstreme has the disadvantage to slow down a
segment where are RB1xx with ROS 3.x. (May apply also to RB4xx if they are busy)

What would help: AP should see there is a slow client and keep the TX-Rate up at
54Mbit as it's no problem of the wireless connection and it does not help to send
at lower rates. While the slow client grabs its packets from the Atheros-Card
the AP should feed another client with packets and do not waste Airtime with
changing rates up and down and send packets at low rates.
