Low Ping

Hi,
Greeting from Denmark.



We have a office in Paris that use a Nerim ADSL solution to connect to the
Internet - with a Sonicwall VPN/firewall box - so they have a VPN connection
to the head office in Copenhagen, Denmark.



They mainly use it for connect to a MS Terminal Server - and therefore the
delay / ping time need to be low.



Now its 100ms to Denmark, but I can see on http://www.grenouille.com/ that
you have rather high ping times in France!



It's typical in Denmark, locally, to have between 15 and 40 ms.



Between the head office and the office in Norway the ping time is typical 30
ms.


I understand from www.art-telecom.fr/textes/avis/03/03-1103.pdf that FT now
can offer low ping times. (!) -

Or are they ready to release the product?



What about other ISP's - Tiscali, Easynet, Nerim can/will the also offer low
ping?



Thanks in advance

Frans

Not actually, AFAIK...

We are all looking after this option, but except the ART mention, not even a
word come out from France Telecom, the main ADSL Telco...

There are three types of subcription in France :

* Subscription to Netissimo / La Ligne ADSL from France Telecom, and a
separate subscription to an ISP linked to that system : Ping extension will
be available directly from France Telecom.

* Subscription to a "pack" from an ISP that use France Telecom for your
lines : France Telecom is said to have an offer for the ISP to resell ping
option. Even when this come out, ISP will be free to handle that option ...
or not ...

* Subscription to a "pack" from an ISP that don't use France Telecom for
your lines (by eg : LDCOM) : No ping option, though these competitors of
France Telecom generally use medium interleave (~40 ms latency) instead of
the France Telecom full interleave setting (~65 ms latency).

* I've just seen in this Newsgroup that Free, the only one to use Free
Telecom Telco where this later is present, will have also a 'ping'-like
option...

Only France Telecom employees could give us some hints, well... either
nobody knows, or their management doesn't allow 'leakages' .... :-)

"Wait and see" : That sentence suit perfectly to the current situation !!!

Aha.... now I know a lot more than before :-) Thanks!!

You write "eg:" - so there are others? - Is there some sort of a web list
over ISP's in France ?

It's a little bit more stricky than that ... You know, french people doesn't
like simple things ... :-D

In the ADSL world, you have to separate Telcos (TELephon COmpanies) and ISP
(Internet Service providers).

Telcos are there to do the transport of data between the user and the ISP.
The goal of the ISP is to allow connexion to the Internet and to handle
local servers (http, smtp, pop, nntp, and sometimes others).

ADSL can be seen as this :

User
|
(phone line)
|

-----
|| Splitter ------ (POTS Plain Old Telephony System)
|| |
|| (ADSL data)
|| |
|| DSLAM (5-6km far away, max.)
|| |
|| ...
|| |
-----

|

-----
|| BAS (AC Access Concentrator)
|| |
|| ...
|| |
-----
|
|
ISP


Ping is altered by a setting in the DSLAM itself. And this is not handled by
the ISP, but by the Telco...

There are two parts of the path between the user and its ISP, first one is
the near one : the DSLAM. The second part is the BAS.

In the light of this, Telcos can now be seen to a new classification :

* "Option 5"

France Telecom and only it assume both the DSLAM and the BAS.

ISP can ask France Telecom to connect the different BAS up to their
connexion point (FT does the transportation, the user login will be like
user @ ISP), or to have someone else to do the connexion (user login is like
user @ ISP . Transport)

* "Option 3"

France Telecom handle the DSLAM, but the DSLAM output is sent to a foreign
BAS. Rarely used...

* "Option 1"

Here, both the DSLAM and the BAS (when the BAS concept exist !) are handled
by the Telco. France Telecom only manage the phone line and the ADSL
splitter, and that's all.

The Telco companies I've seen mentionned in this newsgroup are :

- France Telecom (Preferred ISP : Wanadoo, allow connexion to most other
ISPs.
Have the widest DSLAM network actually, and have no competitor in many
areas)

- LDCOM (ISP: 9Online, but as Wanadoo, allow connexion to other ISPs...
Clearly want to be a France Telecom competitor (using Option 1)... In the
areas where it is present... Many low cost 1024 kbps ISP offers are using
this Telco)

- TD (Télécom Développement, ISP Cegetel ?. It has been many months that
there are rumors of ADSL offers to be out next month ...),

- Colt (ISP : ? - Firms oriented),

- Easynet (ISP Easyconnect - But in easyconnect pages, there is France
Telecom mentionned everywhere in the ADSL pages),

- Free Telecom (ISP Free, no others. "Special" because : The only one to do
IP over ATM directly, that set its DSLAM at more than 2000 kbps, that only
handle one ISP. Option 1.)

To my knowledge, only Tislcaly (ISP) is trying to do an offer using the
"option 3" facility. See their 1024 offer at 40 Eur "everywhere in France"
... I don't know what Telcos or carryers are used...


So to summarise :

Most of ISP are using France Telecom as Telco, through "Option 5".

In some (very) big cities of France, ISP can use other less expensive Telcos
in "Option 1" mode. Mainly LDCOM, or in the case of "Free dégroupé", the
Free Telecom Telco.

One ISP (as far as I know) use France Telecom DSLAM, but use other BAS
("Option 3") to lessen the cost.

Cable) : www.grenouille.com .
