I would like to see acceptable speeds from the customer CPE to the first

Surely this is completely subjective?
Wearing my end-user hat, I see, and expect, TCP traffic flowing at
about 55kB/s on a BT Home 500 circuit, and proportionally higher
My email was confusing since I said the word speed, I would like to ms
roundtrip for the following:
1. CPE to first layer 3 hop
2. CPE to first layer 3 upstream hop
3. CPE to layer 3 exit point of upstream
Example:
Trace route to
www.yahoo.com
1. 10.10.10.1 (CPE) 1ms
2. 10.10.10.254 (DSLAM)(cte)
I have found that acceptable speeds for residential users will vary widely
from one area of the country to another. To a large degree it is a perception
issue rather than an empirical one (ie www.cnn.com loads too slowly). The
best metric for the happiness of a DSL customer base seems to be
Traceroute is not an effective measurement of performance. Due to the way
routing devices process the packets it receives, it is possible for the latency
that appears in a traceroute is far higher than the latency of traffic
traversing that device.

Yes, but I have to hold my upstream accountable for the level of service
they provide to me and eventually to my end customer.
We have ways to measure download speed and ms response time from my network
down to the customer and them from my network out to the internet via our
upstream. However
Andrew, traceroute is an effective tool is measuring roundtrip in ms
format. I am not looking for download speeds or standards, I have already
established those. Yes I agree, traceroute is not an effective tool for
measuring download speeds.

Expect ~20% less than rated speed for ATM overhead.
Expect 20-40 ms on first hop due to DSLAM interweaving.

No, it's not, because routers generate ICMP TTL Exceeded packets with
totally different machinery, separated from the forwarding path. Many
factors influence the ms numbers traceroute reports (MPLS,
