Indeed, we do have multi-hop peering sessions on one of our route
collectors (rrc00). That one is specifically used for multi-hop
peerings.
On the other collectors, placed on a specific exchange, we prefer to
only have peers from that exchange, to prevent confusion.

However, we can not accept unlimited numbers of peerings, especially
peerings where we receive a full table, multi-hop or not.
The maximum appears to be around 15 for each collector, depending on the
hardware used for it.

If you think we should have a peering with someone that we don't have
already, perhaps multi-hop, we are interested to know (with an
explanation).

(and we are always interested in any suggestions to improve RIS)

Well, some time ago we opened a ticket to create RIS peering, and it 
was set up but didn't work, because they didn't realize it'd be 
multihop (about 3 hops).  The peering was cancelled.


Below is the explanation (NCC#2005120077 rrc07):

===8
Actually we didn't notice immediately the request was meant to be for
multi-hop.

We normally prefer not to configure multi-hop sessions. It would be
preferable for us if you are present at the common IXP location with
the RIS project so that we can establish a session there.

You can check out locations at:
http://www.ripe.net/projects/ris/docs/peering.html

The sessions are now cancelled.

This policy was not, AFAIR, available in any public documents.

So I wouldn't be surprised if RIS's coverage was somewhat limited.

 Well, some time ago we opened a ticket to create RIS peering, and it 
 was set up but didn't work, because they didn't realize it'd be 
 multihop (about 3 hops).  The peering was cancelled.

A disclaimer in advance: this was far before my time here.

Part of the explanation is true.
If you are present at one of the IXPs where we are, we prefer to
configure the peering there.
Also, we only configure multi-hop on our exchange-connected RRCs in very
rare cases, as it could confuse people.

RRC00, which is not connected to any exchange, is the dedicated rrc for
multi-hop sessions.

 This policy was not, AFAIR, available in any public documents.

Part of it was, but perhaps a bit hidden. I'll clarify it and add it in
a more obvious place.

It was here:
http://www.ripe.net/info/faq/projects/ris.html#18

The RIS FAQ says:
 Note: Since the database update capacity is currently limited, we do
 not accept any new peers on RRC00. However, do not hesitate to contact
 us if you can provide us with data that is complementary to what RRC00
 already collects and we'll see what can be done.


 So I wouldn't be surprised if RIS's coverage was somewhat limited.

Would anyone? The view of RIS is always limited by the amount of data we
can process and the locations where we are present.
Therefore, we would be very happy to hear ideas about how to improve the
usefulness of the data we collect.
Should we get more full feeds at exchanges (requiring bigger hardware)?
Or more locations? Which locations? Or accept more multi-hop?

 Well, the undocumented fact is that RIS does not accept multi-hop BGP 
 peerings, which may somewhat limit its coverage.

this is a good thing.  as multi-hop bgp is very fragile, measurements
go borkville just when you want them the most.

While that is true, it does help in the cases when there is connectivity
between the two BGP speakers in question. For instance GRH would not
have been possible if it was not for multihop-bgp. Indeed when
connectivity breaks, it is useless, but most of the time it works and
then it is great to have.

A better requirement for RIS could be that it would be advised to be
present at an IX and peer there, otherwise offer the option of
multihop-bgp so that people who are not too-well connected can also
contribute to it. The ones present at the IX's are also the ones which
will cause multihop to break when the IX or they themselves go down, the
remote participants are most likely smaller players thus them going down
and going off the system doesn't really hurt a lot, except them.

Greets,

Network end users to pull down 2 gigabytes a day, continuously?

2007-01-05 Thread Thomas Leavitt
If this application takes off, I have to presume that everyone's 
baseline network usage metrics can be tossed out the window...

Subject: Using Venice Project? Better get yourself a non-capping ISP...


I am one of Venice' beta testers. Works like a charm,
admittedly with a 20/1 Mbs ADSL2+ connection and
a unlimited use ISP.

Even at sub-DVD quality the data use is staggering...

Venice Project would break many users' ISP conditions
http://www.out-law.com/page-7604
OUT-LAW News, 03/01/2007

Internet television system The Venice Project could break users' 
monthly internet bandwith limits in hours, according to the team 
behind it.


It downloads 320 megabytes (MB) per hour from users' computers, 
meaning that users could reach their monthly download limits in hours 
and that it could be unusable for bandwidth-capped users.


The Venice Project is the new system being developed by Janus Friis 
and Niklas Zennström, the Scandinavian entrepreneurs behind the 
revolutionary services Kazaa and Skype. It is currently being used by 
6,000 beta testers and is due to be launched next year.


The data transfer rate is revealed in the documentation sent to beta 
testers and the instructions make it very clear what the bandwidth 
requirements are so that users are not caught out.


Under a banner saying 'Important notice for users with limits on 
their internet usage', the document says: The Venice Project is a 
streaming video application, and so uses a relatively high amount of 
bandwidth per hour. One hour of viewing is 320MB downloaded and 105 
Megabytes uploaded, which means that it will exhaust a 1 Gigabyte cap 
in 10 hours. Also, the application continues to run in the background 
after you close the main window.


For this reason, if you pay for your bandwidth usage per megabyte or 
have your usage capped by your ISP, you should be careful to always 
exit the Venice Project client completely when you are finished 
watching it, says the document


Many ISPs offer broadband connections which are unlimited to use by 
time, but have limits on the amount of data that can be transferred 
over the connection each month. Though limits are 'advisory' and not 
strict, users who regularly far exceed the limits break the terms of 
their deals.


BT's most basic broadband package BT Total Broadband Package 1, for 
example, has a 2GB monthly 'usage guideline'. This would be reached 
after 20 hours of viewing.


The software is also likely to transfer data even when not being 
used. The Venice system is going to run on a peer-to-peer (P2P) 
network, which means that users host and send the programmes to other 
users in an automated system.


OUT-LAW has seen screenshots from the system and talked to one of the 
testers of it, who reports very favourably on its use. This is going 
to be the one. I've used some of the other software out there and 
it's fine, but my dad could use this, they've just got it right, he 
said. It looks great, you fire it up and in two minutes you're live, 
you're watching television.


The source said that claims being made for the system being near 
high definition in terms of picture quality are wide of the mark. 
It's not high definition. It's the same as normal television, he said.
