[Fwd: [Chapter-delegates] New Papers on Internet Exchange Points]

was topical earlier - might be useful

From: Karen Rose <rose@...>
Subject: [Chapter-delegates] New Papers on Internet Exchange Points
Date: 2008-09-01 11:40:23 GMT
Dear Colleagues:

ISOC recently published two new papers on Internet Exchange Points. 

The first is "Promoting the Use of Internet Exchange Points:  A Guide to 
Policy, Management, and Technical Issues."   It was written for ISOC by 
Mike Jensen, who is Internet development expert from South Africa.  Mike 
participated in ISOC's best practices session on IXPs held at the 
Internet Governance Forum (IGF) in Rio last year.  He is also an active 
adviser to the Association for Progressive Communications (APC).  A PDF 
version of the report is located at:

The second paper is a short overview of IXP essentials drawn from the 
above report.  The PDF is located at:

Both of these reports, as well as additional documents on Internet

That most probably was rather them buying SDN (Satellite Data Networks)...

What exaflood? 'Net backbone shows no signs of osteoporosis

What exaflood? 'Net backbone shows no signs of osteoporosis
By Nate Anderson

Given recent media coverage, it's easy to believe that P2P and streaming
video traffic is a rising hurricane battering upon ISP levees, that ISPs
are frantically sandbagging their systems against disaster, that
throttling, bandwidth caps, and traffic management are urgent and
absolute necessities to keep the storm surge at bay. But new research
from Telegeography only confirms what we've been saying for some time:
the Internet backbone isn't drowning beneath any kind of exaflood. In
fact, backbone capacity has grown faster than Internet traffic in the
last year—for the second year in a row.

Telegeography monitors utilization levels on major backbone lines, not
on last-mile connections, and it does so around the world. While some
major links are seeing traffic increase faster than capacity (the
US/Latin American links are the prime suspects), most links actually saw
decreasing utilization this last year.

Not the usual

Hello All,

These days IOZ seems to be a place where one can informally lodge a complaint by airing their dirty laundry
about the poor service delivered by so and so and hopefully jumpstart a resolution so I thought I would do
something different for a change.

We have recently had an issue that was caused by a very unique set of circumstances that was causing some of my
customers pain.

I have worked very closely with Verizon (who are not my ISP, nor are they in any way obligated to help me) to get
this issue resolved as it impacted some of their customers and they have bent over backwards to assist in
firstly identifying the root cause of the problem and secondly identify the solution.

The various members of their team that we have had to work with (including some of their subcontractors)
have worked tirelessly and have really gone the extra mile.

For this, I felt a nice public pat on the back was necessary.

You failed to clarify whether they actually succeeded :-)

But I believe you have made appropriate use of the mailing list.

Customer feedback all .za ISP's want.

Dear Customer, we have received your complaint and investigated, and
we have concluded the reason your access to is so slow
is due to xxxx isp having congested links, and while we peer adequately
we can only encourage xxx isp to install enough infrastructure to peer
adequately with us.

Alternatively, we can suggest that move over to us,
and we can ensure your connectivity to is always

Your Support team that can't answer a phone.

Not that I'm someone who everybody takes note of,
but the sheer unprofesionlism of peering in .za is disgusting,
and now even google is getting in on the act if reports are
true, I'm at the point were I'm acknowledging that the corporate
mentality has soiled what the Internet was in the past, no
pun intended, and South Africa under it's new leadership
is no exception, whatsoever.

Re: Customer feedback all .za ISP's want.

I'm a little confused by this, Daniel (message below) - but then I'm a bear
of little brain ;-)

I presume that the "feedback" that you've quoted is imaginary? I get mixed
messages from it, especially when reading your postscript as well.

Yes, I agree that peering in SA is suboptimal, but I am not in the least
convinced by your use of the term "unprofessional". There are two simple
reasons for the sub-optimality: -

1	As I mentioned recently, SAIX really don't want to peer with anyone,
as they are suffering from schizophrenia between their role as a wholesale
ISP and their role as a part of an almost-monopoly and still very much
dominant Telco. Where they do peer, the links are almost always congested to
a greater or lesser extent

2	The cost of local connectivity is so high (higher, in some cases,
than international connectivity), that many ISPs can't afford to install
sufficient capacity to JINX. See point (1) above for an explanation ...

A third, related, factor, is that SA is a very large country, with many
ISPs. Some of those ISPs only operate in a limited region, and rely on their
upstream connections to carry their traffic elsewhere in the country - over
very expensive national connections.

All this is set to change.

a	JINX is currently undergoing a huge increase in capacity, and
several peers already have Gigabit connections which will be active soon -
and then upgraded to 10 Gbps. The delay in at least one case relates to the
