Hi folks,
The tentative agenda for NANOG44 will be released shortly and registration
will open for the October meeting. There are many time slots marked as
'speaker - pending' or 'tutorial - pending' due to abstracts lacking actual
presentations. We believe there are many good ideas lurking with
As Valdis stated earlier:
I predict that if you graph it, there's a ton of packets that are right

the ACK's of the mobygrams, and then a small noise level of "everything else".
That's pretty much the case for the last
Greetings all,
We've been asked to look at building an ISP in Sri Lanka and I
wanted to know if anyone had any of the following:
- Transit providers in Colombo
- Types of handoff's common in this location (Ethernet, ATM, etc)
- Expected US$/mb of flat-rate traffic
I have a need for cheap managed DC power switches for our OSS and
Monitoring (backoffice). I was wondering what everyone else have
found in this space. I am currently using Cisco 2950's, but those are
still 2.5K list and seems like too much to spend on something so
trivial.

CAIDA has been doing a lot of that, at least in the past. Last I asked
them, which was quite a while back, they said that O(35%) of traffic
in their samples was at the path MTU (which included 576 bytes for
historical reasons), O(40%) was about the size of a TCP SYN or ACK,

Hello folks,
Is anybody aware of any papers with real-world data about IPv6 fragmentation?
I'd be interested in something along the lines of:
Shannon, C., Moore, D., and Claffy, K.C. 2001. Characteristics of
Fragmented IP Traffic on Internet Links.
(but that focuses on IPv6 fragmentation, rat
2.5K? No way. Get used or refurbished from Network Hardware or similar outlet.
We rarely buy new. Used gear works just fine.

Or at least buy Cisco refurb and save $$$...;)
We have lots of 2950's in use ... moving to 2960's for low end
applications currently - then moving to 3560 etc from there
You might also checkout the Express500 stuff... more basic switch and
priced right.

Hello,
During the last years, there have been many discussions about the
scalability of the Internet architecture notably within the IRTF RRG.
With IPv6, thanks to its huge addressing space, it is possible to design
protocols and mechanisms that are more scalable and more powerful than
with IP
This is about what I would expect but as others haev noted does not
include jumbos.
This says that the majority of packets are session control and
open/close sequences on the one side and big, fat, WRED eligible data
packets on the other side.
This is consistant with the trends of youtube, "high

Pleas
try getting a 2980G-A switch off of ebay. for 100bucks you get an 80
port 10/100 switch. sure it's EoL/EoS already but it works pretty
well.
cisco refurbished equipment will save you a lot of money. I've been
dealing with these guys:
