Ethernet question

Possibly a little off topic, but can anyone tell me what size pipe
would be required to carry 100Mbit or Gigabit Ethernet between two
locations? The cct wouldn't be shared with anyone else, one site would
be connected exclusively to the corporate network box (whatever that
may be) about 150 miles away

I am assuming there is no correlation between say a 100Gbit ethernet
and an STM1 cct - i.e. I wouldn't need a 155Mb cct to carry it, but
I'm more than a little confused and am finding it difficult to find
the info

Er, so order a dedicated fast/gigabit ethernet circuit then? BT, CW and
Virgin Business (or Telewest Business if they are still called that)
will supply such a service.

Not as simple as that - the agreement I have with our IT types is that
they will supply the box if I source the cct. I have access to ccts
between 2Mb and upwards - I just need to know what size I need.

You need a 100Mb or Gb leased line circuit. These are standard BT
offerings. Do be prepared to pay for them though. BT will install fibre
at each end and give you a terminator box with an ethernet socket to
plug into.

(My experience of them is that they're not auto-sensing either, so do
make sure you have kit that you can fix the speed and duplex settings on!)

Or they'll try to sell you into their MPLS network, but just say no,
if all you really need is point to point,

Thanks for your reply - I will be able to provide the cct myself,
without going to BT - but I need to know what size cct I will need -
what is needed to carry a 100Mb or Gb ethernet?

Cooer missus,. A fucking EXPENSIVE pipe.

You would need something like a 155mBit to carry it. Or a private fibre :-)

I am not sure what BT or energis would offer you in this mode.

A frame relay connection would do it in burst, if that is the issue. I
think.

But realistically if you have 100Mbps in a local lan, the usual solution
is to work out what actually needs transferring and what rate is
acceptable. Without knowing whats going on, my approach to situations
like his was usually to construct a lower bandwidth link, and modify the
applications either side to make efficient use of it.

If you can hint at what runs over it, I might be able to suggest
alternatives.

Fiber or microwave over any distance.

100mb of course. If you dont want degradation ..

On one per desk basis, you could have each user with 448k/3Mbps..

Thats actually very usable. ;-)

It all depends on what's gong on between..

I think one of the biggest private (non ISP) pipes I ever worked on was
an Internet based pipe between London and new York. Guess what. Getty
Images..massive data flow of high res pictures.

We built a mirror system IIRC so that images uploaded in one location
got transferred more or less when bandwidth was available to the other.

Do the bulk transfers in the wee small hours when both towns are asleep.

the worst thing for a network is MS servers - file servers.

Now I can and do run SMB over a 30KBytes/secondlink, but its dog slow.
Its dog slow at 10Mbps :-).

I generally pull the files I want across, make a coffee, then when they
arrive, work on them, and put them back later.

AFAIR a long time ago when I did Cisco stuff, is it not only Workstations
that should are 'acceptable' to be auto-negotiate and everything else
should be fixed. BT being BT would probably say 'well, it's what Cisco
say' - like they do. I just wish I could find the old Cisco text where I
read it all those years ago. I'm sure Gordon has it somewhere ;-)

I would be looking to hang four or five PC's max on it. Three of these
would have to be able to access 3 or 4 remote servers that carry real
time info and all would have to be able to do the usual internet,
intranet and email. Two of the servers are some sort of Unix while the
other two are Windows types. may possibly want to add access to two
more servers within the next 12 months.

At Present we use a 2mb pipe which is shared by two other geographical
locations and is really slow - my IT dept has promised that if I can
provide the pipe, they will provide the kit to hang on my end of it. I
can probably find a spare STM1, but if I can get away with something
smaller, all the better. I don't need to go to C&W or BT etc, but I do
need to know what size pipe I need to arrange 0- this ethernet thing
is very puzzling :-)
