| [OK] Major packet loss--- can't watch video online?
Been having a ton of trouble watching any online video on Youtube, and news sites. They stall or stop loading.
I ran a line quality test here at bbr and got this result:
»/linequality/nil/2378703
Could it be the massive packet loss is what's causing the problem?

Newport News, VA | What you are seeing is not true packet loss but packet prioritizing. If it was true packet loss then the hops after that would also show at least the same amount of loss. |

| does this mean we can't view online video anymore?
I don't get it.
we should be able to do whatever within reason.
i went bonkers one time and did a 320K audio test just to see if it can hold and it did.. solid as a rock.

He simply pointed out that what the OP was showing was not packet loss - the OP can infer from that that the root cause of the issue was likely elsewhere.
I have seen this from online videos before - it is possibly server or network issues on the far end. |

Thanks for the info. I know something is up, but can't figure out what.... BTW if the packets don't come back, how is prioritizing any different from loss? |

| said by KrK :BTW if the packets don't come back, how is prioritizing any different from loss? That's an excellent question. The reason is that both ping and traceroute use a special packet type called an Internet Control Message Protocol or ICMP packet. These are used primarily for network attached devices to send short messages to each other and as such are very different from transport protocols such as UDP or TCP, which is what 'real data' such as web pages or video downloads use.
As more computers moved from temporary connections such as dialup to permanent connections as we have today, it became common for virus and trojan writers to include a mechanism to search for nearby hosts via ping in an attempt to locate more systems to infect. The net sum of having to manage this additional flood of ICMP packets was that routers, firewalls and other network devices could become so busy responding to pings that they were rendered ineffective at actually sending real traffic...what is known as a denial of service attack.
This is why it is now common practice for engineers to setup their devices to treat ICMP with the lowest priority, if now downright ignore it (my Juniper firewall at home is set to ignore ICMP and thus can't be pinged) This is what is often called "de-prioritization" here and helps to ensure that 'real packets' get through before the fluff.
This is what you are seeing when you do a traceroute and one hop is showing loss or high latency while the next is just fine. You can tell it is just a case of the host in question taking its time to respond because if there was real packet loss that host would impact all the other hops because it sits between you and them.
and there it is in a nutshell, albeit a lengthy one <grin>
hope this clears the mud a bit. |

I wish this tutorial we are getting here was a "sticky" so we can just refer to it when someone comes in thinking they have PL. This info is very good.

OK, that makes a lot of valuable info.
One last question, I'm getting a lot of "Connection Reset by server" messages like when I click on links, etc (Examply I clicked Reply to your post a second ago and got the browser Connection reset" message and had to hit "Back" and then try again. These never used to happen but are common now.... could it be related?
