|For teleworking that goes
beyond e-mail & World Wide Web you will need high density, high capacity
and high-speed telecommunications links to your company or provider instantly
- anywhere and anytime in the world. So far we don't have this ideal situation
yet, but let's have a look at the different technologies we have for going
|For going online, you have at least three different modes you can chose from. Most companies only support one of these modes. All the modes depend on the technology you use for going online.|
| We talk about "Remote Control"
if there is a host & a client and you work on the host instead of your
own connected computer. You have to possibilities to use full CPU
capacity of the host, because the applications are running on it and only
the monitor image is transferred (i. e. X-Windows, Telnet).
Because the monitor image is transferred, you need a quite fast line
to your remote host if you are running graphic intensive applications such
as Windows 95/Windows NT. Otherwise if you stay to plain text, you just
need a modem for character transmission which is really fast enough today
for ASCII-oriented applications.
| If your computer gets really connected
to a LAN as a remote client, we talk about "Remote Node". Your computer
has the same privileges and possibilities like your local client in the
company. But be aware, if you work with large files, they need to be downloaded
first - what would take quite a while for a big file (it can take you minutes
or even hours). Even more, all your applications you want to run, need
to be installed first on your computer.
There are different specific applications like Lotus Notes, Microsoft Exchange, etc. which have their own possibilities for connecting to the LAN, but then you are limited to the use of the specific program.
|Remote Access with Internet:|
|With Internet you have a lot of different
You can use native Internet Programs for your work like e-mail, Telnet, FTP, WWW, WAIS, News, Gopher, etc. But most of these tools are not explicitly made for teleworking, but for one specific task.
"Remote Control" techniques are also possible with the internet. They work the same as if you would connect direct to the host - but mostly you have an even more limited transmission bandwidth during rush-hours. Telnet can be used for connecting to old teletype hosts, which are still very common and which have a splendid performance for teleworking today - but you have to forget about graphics!
You can connect as a Remote Node using the Point to Point Tunneling
Protocol which allows you to tunnel your "LAN-Traffic" through the Internet.
The LAN-Packets are encrypted & signed before sent over the internet.
(Like a safe tunnel through the mean and dangerous Internet.)
