INTERNET FOR INTERNATIONAL TRAVELERS and SMALL OFFICE
- ON-LINE !!
This article is, of necessity, somewhat technical.
But, it should give the Manager a conceptual understanding of the
subject while still providing enough information for the systems people
to further develop these concepts to meet the unit's specific
requirements.
UNIVERSAL INTERNET ACCESS
One of the major problems facing travelers is access to
the Internet for connection to corporate and other services. We have
been working with hotel management companies who are facing this
problem every day, especially for their executives who travel
internationally.
Within the US the problem is not difficult to solve or expensive. The
travelers must have accounts with a nationwide provider like AT&T,
MCI, Mindspring, Netcom or others.
International access is a problem because each country
has its own providers, introducing the need to make long distance calls
or use an international 800 type access to reach the US.
Internet service providers have banded together, on a
worldwide basis to alleviate this problem. They have set up a
consortium called Global Reach Internet Connection (GRIC) network that
utilizes software developed by AimQuest Corporation to allow travelers
to call into a local Internet service provider and be treated as if
they are connected to their 'home' service. Critical to this group is
the recent addition of Netcom, a nationwide provider of service within
the US. As a result there are now about 40 countries, including the US,
where a traveler can use a local Internet service for $4 to $6 per hour
to make connections to his personal or business accounts, without
having to have an account within each country.
SMALL OFFICE - BIG CONNECTION
We have been talking about the future and theories for
the last year. It is now time to review a real application of
communications.
Our small office recently upgraded its communications system to allow
more effective connections to the outside world. The systems that we
installed and approach that we took can be applied to most hotel
administrative operations. It could also streamline many standalone
foodservice operations.
Prior to the change, we had been utilizing dialup
connections to reach the outside world. While functional, the approach
was slow and almost always required manual intervention. At the very
least, the computer making the connection became very slow because of
the processing overhead associated with "serial communications". You
could perform other functions, but, you often had to wait for the
screen to catch up with your typing.
Our change was relatively small technically. The result
was, however, dramatic on performance. We added an inexpensive ISDN
router to our three PC network. We also added a 'shareware' mailserver
to offload the PC program overhead. Interestingly enough, all of the
network, mail and WEB server functions were added to the 'obsolete'
486/66 PC that I am using to write this article - and performance
improved.
The new network allows us to replace two telephone lines
with the digital service for about $20 a month more in service.
The big change however is that we can now load up to 8
different hosts into the router and our local network will treat them
as if they are always connected. Connections take a second or less (if
you monitor the router).and are barely noticeable. The system hangs up
whenever it is not used for 30 seconds or so which saves big money in
areas that charge message units. How often do you study or browse
through a single complex WEB page? With this approach, most of the time
you will be off-line and not even know it.
While our office only utilizes TCP/IP, this specific
router also supports IPX (Novell) and frame relay. The cost is very low
for the capabilities provided: $720 for the Router and $200 for the
ISDN installation. Most amazing was that it worked on the first try.
Hotel & food service operations could use this one
device approach for connecting to their various service providers
including corporate & regional offices, credit card verification,
credit card account clearing, product and service providers.
The two ISDN "B" channels can be used to transfer about
1 million Bytes per minute to two different locations at the same time.
The "D" channel can be set to be on-line all the time for credit card
related activities.
The speed impact is shown in more than just the
communications line acceleration. The overhead in the PC is
dramatically reduced because the transmission is through a "LAN"
connection which does not place a burden on the PC. Even the best of
serial communications require that the PC handle between 1 to 16
characters at a time. Out TCP/IP setting allows blocks of 1500
characters to sent at one time there by reducing the number of PC
processing 'interruptions' by 99%.
Care must be taken in the selection process. Routers by
different manufacturers have very different capabilities. Also, buying
an 'ISDN Modem' that installs as a card in a PC does not provide the
capabilities discussed above. Other PC's cannot access it without
burdening the host PC and these cards are still treated as serial
devices that add big overhead when you try to utilize the full speed of
the ISDN connection - 128 Kbps, basic, up to 500 Kbps compressed.
Let me know if you would like to hear more details
specific to an application. Also, for anyone who would like to know
more about the basics of ISDN and its business applications, we can
provide a copy by E-Mail of a document that we assembled on the
subject. All we need is your Internet E-Mail address. Send any requests
