- I plan to change my network connection. Please help me decide how.
-
- I don't know that the groups I've selected for this posting are
- appropriate. If not, please steer me to the right place.
-
- Is there a faq I should read?
-
- Please respond by email. I don't read these groups.
-
- I am trying to decide what kind of network connection I should seek.
- I have been a satisfied user of UUNET for years, but I believe that I
- can now get service better matched to my needs and at lower cost. I
- am a single-user site A and seek dial-up connection through a local
- Internet node B which might be commercial server or a university. I
- can think of two kinds of connection:
-
- Terminal. A appears to B as a ``dumb terminal''. A has a
- user account on B and must log in after calling.
-
- SLIP (or PPP). At least for the duration of the dial-up
- connection, A is a full-fledged node on the Internet.
-
- Are there others I should consider?
-
- Based on a few impressions I've picked up, a terminal connection can
- be lots less expensive than a SLIP connection. One thing I'm trying
- to do is clearly identify what I'd get for the extra cost of SLIP. So
- I compare the connection modes in their support of various network
- services:
-
- email
- news
- ftp
- archie, gopher, etc.
-
- In the following, I describe _my understanding_ of how these services
- work in the two cases. My main question is whether my understanding
- is accurate and doesn't overlook important issues.
-
- email.
-
- Whether A is a terminal or has a SLIP connection, incoming email is
- queued at B until a connection is made. If A is a terminal, the queue
- is A's user mailbox and A empties it by reading it, perhaps with the
- help of a mail-reading utility. On the other hand, if A connects
- using SLIP, the queue is just another part of network traffic destined
- for A which will be automatically transmitted when the connection is
- made. The mail then moves to a user mailbox at A, but since A has but
- one user, this queue contains all email originally present in the SLIP
- queue. The volume of traffic over the dial-up connection doesn't
- differ very much between the two cases.
-
- There's the issue of what email addresses are possible in the two
- cases. With SLIP, A can retain its registered domain address and B's
- address or identity need not be apparent in A's address. As a dial-up
- terminal, this may not be possible.
-
- news.
-
- Let's say that B is a major site that takes all of the news. If A
- connects as a dial-up terminal, the user at A can browse any of the
- news. The news is left undisturbed at B, although A may of course
- capture to its own local files as it browses. If the connection is by
- SLIP on the other hand, site A must subscribe to the news groups it
- wishes to see, this news and none other is automatically transmitted
- to A's site when the connection is made, and I don't know if A could
- readily browse news to which it does not subscribe.
-
- ftp.
-
- With SLIP, A is a full-fledged node on the Internet and can browse
- directories and files anywhere else on the Internet in real time,
- capturing files at will. The same is true for the terminal case,
- except that the ``capture'' is to a file at B, not A, and A would have
- to do another step to get it further transmitted to A.
-
- archie, gopher, etc.
-
- These search tools seem to be equally available, whether as a dial-up
- terminal or through SLIP.
