Is this packet loss?

post #1 of 19
Thread Starter 
I've noticed a few funny things going on lately (rubber bullit's) while gameing, I play only one game and the server is in Texas.
I have also read where the internet (hop) point's along the route know if it's receiveing test packet's or not and drops some on purpose as not to clutter the lines, I don't know if that is true or not?
What I do know is it did not use to be like this! and I'm with Comcast Cable with a 22mb speed, any thought's?

according to the pingplotter there does seem to be some packet loss. Packet loss could happen for a multitude of reasons tho. What you were talking about intentional dropping is done with either firewalls/IPS (dropping all packets) or via QoS with class of service.

Based on what I am seeing tho it looks as if Comcast is pulling their typical oversubscribing of an area.
Sadly, it is not Comcast that is your bottleneck but AT&T which is providing the backhaul to the internet itself.

I saw that ATT stuff on there and was confused, So when Comcast is overloaded they must have a deal with ATT to leach their services??

no not necessarily, Comcast is an end user provider, a.k.a. Local Telco. They do not have full WAN connectivity across the entire country or world, in order to provide the WAN connectivity they go through a larger Service Provider. The big ones are still Sprint and AT&T, there are some others but there isn't that many. Another example would be for WAN's spanning the globe, that number drops even further.

A ping test is a little different to gaming and it isn't practical to use a ping test to determine gaming playability.

Gaming usually uses UDP which does not require an ACK reply or number sequencing.

Ping uses an ICMP echo packet. Which coincidentally requires a reply which is used to determine the actual MS.

run a few pings that will send like 30 responses to a friends computer in another country. If you loose a significant %% of packets then be worried. Packets get lost all the time, games are UDP which means they don't guarantee the packets make it back to the client.

Even if there is packet loss it's unlikely you'll be able to anything about it if it's past your local exchange.

WOW, did'nt know that about comcast! If ATT is the big dog, how come comcast has the higher speed's? I was with ATT on their fastest 15mb speed, but after the U-Verse thing kicked off my ping times went from 35 to 85ms, so i switched.
The cable does have a weird fluction of ping times. But I can't comeplain about a 30 from 80 diff. It must just be conjestion, I'll just keep my eye own it!

Yes at&t is still one of the big dogs, most places can't afford OC12's and higher

the one before the loss has started is the problem. In that pic the 68xx IP is your culprit
