RE: SATELLITE DSL WITH EXCHANGE SMTP?

Title: Message

Thanks Carl, the consensus appears to be that 70ms is a measure that is acceptable in the Exchange SMTP scenario, and more critically with remote access too.  Would love to know if there is a standard for the industry to measure latency? It would give much more creditability to the 70ms latency measurement given here by this company (SkyPipeline) before spending $1000 on installation and equipment.   Here is what a “Product Developer” from MegaPath had to say… “…technology mentioned from skypipeline.com, it is fixed wireless technology. The customer has to be in direct line of sight for one of the ISP's main antennas.  If a customer isn't there's no connectivity. We've also seen evidence that rain can effect the transmission (and if it's really windy and the antenna is jostled around, that affects it, too.) The other issue is coverage.  You have to put up an antenna everywhere to get to anyone.  My suspicion is that 99% of people within range of this type of service are also within reach of our services because these wireless providers go into the markets with the highest population”     -----Original Message----- From: Carl Houseman [mailto:[EMAIL PROTECTED]] Sent: Friday, July 12, 2002 12:51 PM To: MS-Exchange Admin Issues Subject: RE: SATELLITE DSL WITH EXCHANGE SMTP?   70 ms is good enough for most applications, including remote access software.   In fact 70 ms is pretty darn good for wired service.  I used to deal with frame relay where 100 ms was just wonderful, and anything less than 150 ms was quite acceptable.  We were running Citrix traffic across the frame so we would get complaints when latency was bad, usually >200 ms.   Carl -----Original Message----- From: Michael [mailto:[EMAIL PROTECTED]] Sent: Friday, July 12, 2002 11:51 AM To: MS-Exchange Admin Issues Subject: RE: SATELLITE DSL WITH EXCHANGE SMTP? Thanks.  Yes, we were talking about "high speed connection".  The issue of latency seems to be acceptable at certain levels... One such measurement, 70ms, comes from a company called www.SkyPipeline.com.  If latency is an *ENEMY* to good line speed what will it mean to have 70ms using "interactive applications" specifically remote access software?   "...guaranteed to have an average round trip packet transit time within SkyPipeline's Broadband Wireless Network over a calendar month of 70ms or less. The average network latency is measured as the average of 15-minute samples taken throughout the month"   -----Original Message----- From: Benjamin Zachary [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 11, 2002 9:31 PM To: MS-Exchange Admin Issues Subject: RE: SATELLITE DSL WITH EXCHANGE SMTP?   As long as you get static ip it should be okay. Others may complain about the terminology you are using, since DSL is a connection method and so is satellite so I'm presuming you are talking about satellite for high speed connectivity. There will be latency but it shouldn't matter too much -----Original Message----- From: Michael [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 11, 2002 6:33 PM To: MS-Exchange Admin Issues Subject: SATELLITE DSL WITH EXCHANGE SMTP? We are in Ventura County, CA and just found out from the ISP that slots on the D-SLAM may not be available for our IDSL connection.  How well does satellite DSL weigh in with SMTP mail on an Exchange Server environment?
