We can only hope that as TW pushes their VoIP product and more and more
people begin to encounter the problems caused by these latency spikes
and general lack of QoS/CIR, TWC will think about doing something about it.
Hopefully enough TW VoIP customers will understand *why* their calls are
jittery and/or dropped, or will have friends who understand, to hammer
the point home to the folks that fill out the trouble tickets. Maybe if
enough TW VoIP subscribers subsequently cancel their service and the
cancellation ticket says "lack of QoS/CIR led to unacceptable
performance," the decision-makers will get a clue. Hopefully enough
people will not simply put up with paying for crap service, thinking
"it's better than nothing."
And maybe I'll look out the window and see a bright pink 600-lb hog
soaring past.

Time Warner is a "bulk" internet provider. Their infrastructure can
handle QoS and CIR (Committed Information Rate) but their business model
can't.
We've been hammering on them for years to offer higher priced
connections that give users of streaming services (like VoIP) better
service. Their solution is always to throw more bandwidth at the user -
which never, never solves the problem (latency spikes caused by
over-subscription of their distribution switches and lack of simple
reservation queues on those distribution switches).
Time Warner also lacks accountability for providing quality service -
especially on accounts that need consistent low latency. We have had
clients that ran fine on RoadRunner for years then suddenly it all goes
to heck: dropped packets, long latency spikes, etc. Time Warner's only
response in that situation is to send a tech out who does a bulk
bandwidth test and then declares that there is no problem...
I guess that client just ran into a fluke that lasted for a couple of
years - kind of a Roadrunner "el Nino" of calm internet access.
So when it comes to Time Warner, *know* what you are buying. It's bulk
internet access for a nice cheap price. Not something you generally want
your network to be dependent on.

Interesting. Is anybody running RR business class at work? Reason I ask is
my Frame Relay contract for seven sights is up for renewal in about 4
months. Two years ago I looked into RR business class but they did not have
the lines run to my facilities and they wanted me to incure the costs of
running the lines so I said no and stuck with frame. I also could not
swallow the pill of having no CIR or QOS since we run VOIP. I doubt things
(performance) has changed that much in two years. I also spoke with a guy at
a conference who switched to Broadband business class only to swith back to
frame due to lack of CIR and QOS.
Any suggestions would be appreciated.

This is a valid test.
Call RoadRunner tech support and ask for a second level technician as
soon
as they answer the phone.
Work with them until they see the packet losses too. It may take a
while,
but take the time.
They followed this procedure when this was happeneing to me:
1) Dispatched a technician to my house to check the drop from the pole
Result: technician replace the coax from the telephone pole to the box
on the side of my house, but did not fix the problem.
Technician opened a ticket for a problem on the main line.
This ticket was pencil-whipped a day or two later -- problem
still was occuring
A week later...
2) Dispatched a technician to house to check the local drop again --
Result: found everything in good order on the drop and opened
a ticket on the main line. This time they actually
worked the ticket. Two days later problem was fixed.
This resulted in getting the cable modem problem fixed and a noticeable
improvement in my Cable TV signal in the house :-D

Hey folks,
Looking for a suggestion. I have noticed that my VPN tunnels seem to
drop
on a random order.
So I have set up a simple ping cron job, I have it sending out 60 pings
every minute to three servers (one on the RR network {DNS}, one on the
east coast, one on the west coast).
The job is run every minute, so in fact this is a continuous ping that
sends results every minute.
I see that of my 60 packets, I loose a few almost once every 3 minutes.
This seems to affect all three servers.
So my questions are:
1. Is this providing me with a valid network test?
2. What kind of results should I expect?
3. What type of network reliability test would you recommend?
4. What type of network reliability should I expect?
Thanks,
Ron
