Re: [WISPA] Question about hosting client's POS merchant account for credit card processing

Also keep in mind that most transactions done with these machines over 
POTS are unencrypted. So don't try to plug one into a VoIP ATA.

Every provider I have ever talked to supported both mediums.  Every 
customer will thank you greatly for moving them to Ethernet instead of 
dial up - transactions are at least a tenth the time.  Call the 
merchant, say you want to use Ethernet instead of phone (you may need 
dial tone for this migration period!!!) and they'll tell you what to push.

I imagine this may vary depending on who actually provides the
merchant account, but has anyone received feedback from such
providers about their expectations for serving the credit card
machines wireless?  E.g. must you use dedicated, encrypted
wireless links (as common sense would suggest), and/or VPNs, or
must the POS machine sit on a dedicated LAN, etc?

Thanks.

P.S. By POS I mean Point of Sale, to avoid any confusion. ;)

[WISPA] Question about hosting client's POS merchant account for credit card processing

[WISPA] Level 3 acquires Global Crossing

2011-04-11 Thread Mike Hammett 
http://www.telecomramblings.com/2011/04/level-3-global-crossing-finally-get-hitched/
http://www.telecomramblings.com/2011/04/ma-journal-a-lvltglbc-integration-wont-be-that-hard/

How much impact do you think this would have on the Level 3 - Comcast 
situation?

If Global Crossing - Comcast is anywhere near balanced, it should help 
out Level 3's ratio.  However, is the problem more about the ratio or 
the traffic levels?

Re: [WISPA] RED queues out, PCQ queues in - anyone else doing this?

2011-04-11 Thread Greg Ihnen 
Rubens,

Thanks! Yes, I prioritized small ack, syn and fin packets. I think I'm 
seeing an improvement.

Our modem already does caching and I can't control it. It even caches 
DNS which breaks things like OpenDNS. Happily they fixed the http/s caching so 
we're not still seeing week old DrudgeReport pages.

Satellite, huh ? You will probably gain a lot by forcing users to a
transparent proxy. You can do lots of TCP tuning on a server that
would be either impossible on some Microsoft TCP/IP stacks or too
expensive in support hours to do on the end users machines. Caching
also comes to mind.

High priority for ACK packets usually turns into better performance
perception on any network. I would try it for sure, but consider the
proxy option above for your specific scenario (not the usual WISP
one).
