RE: [e2e] source code release

How is 4+4 in any way easier to deploy than 6to4?

Subject: [e2e] source code release

4+4 Open Source Code Release:

http://ipv44.comet.columbia.edu/

for the Linux implementation of 4+4 and tools. The source and i386
binaries are part of the release.

What is 4+4?

4+4 is an evolutionary approach to address space extension and IPng
deployment. 4+4 starts as a NAT-extended architecture that provides a way
back to unique, global, network layer host addresses - through its
deployment end-to-end transparency is restored.

There is no need to change routers. The transition process provides
incentives. The final state of the network is a homogeneous and
transparent Internet that uses 64-bit addresses and a packet format
similar to tunneling.

A paper on: "4+4: An Architecture for Evolving the Internet Address Space
Back Toward Transparency" that describes the design, implementation, and

Re: [e2e] source code release

I wonder if you are aware of our work on AVES, which I believe is related
to your work. The AVES approach is to have intermediate waypoints to
handle the packet translations in order to connect IPv4, IPv6, and NAT
realm together in a transparent fashion without modifying end hosts.

[e2e] Inferring loss at Client-side on TCP

Hello,

I am a grad student working on developing a tool which should 
capture the loss based statistics at the client-side. The possible 
inputs to my tool are tcpdump traces.

Can anyone suggest some heuristics of identifying loss based on 
client-side tcpdump traces.

Thanks,
¬Kalyan C

Depends on the fidelity with which you want to identify them.  You
could always look for triple dup acks and assume whatever losses
you haven't seen.  Assuming you want something more accurate,
Crovella and Barford's Critical Path Discovery techniques would
seem a reasonable starting point.  They present an off-line algorithm
for matching TCP packets with the ACK that released them, which has
obvious application to identifying loss.  However, if your long-term
goal is to do this detection online, it may not be applicable.

Act like any TCP client!!! Whenever you see up to 3 out of order packets,
you may conclude that you lost packets.

Re: [e2e] Inferring loss at Client-side on TCP

Hi,

take a look at our paper:

P. Benko, A. Veres, "A Passive Method for Estimating End-to-End TCP Packet
Loss", Proc. IEEE Globecom 2002, Taipei, Taiwan

Abstract:
This paper presents a passive end-to-end loss
monitoring method, which relies on traffic monitoring at a core
or ingress router interface. The monitoring node captures the
packets of TCP connections generated by end-hosts. Based on
the seen sequence number pattern the loss ratios are estimated
for the two segments of end-to-end path divided by the monitor.
This feature is especially useful if the monitoring node is placed
at the border of an autonomous system, e.g., at the egress point
of an ISP. When applied to mobile Internet access, packet losses
on the radio interface can be distinguished from losses in the
core network or in the public Internet. The packet loss
estimation algorithm is rigorously validated using simulations
and testbed measurements. Additionally, measurement results
and an application example in a dial-up ISP are presented.

Best regards,

Peter
