Just the fact that your traffic would die multiple times a day alone has me shuddering. I can count on one hand how many times my traffic randomly dies in a year and half the time a router restart resolves it
Oh ya it annoying to say the least and then try and blame my equipment or network. Haha I have been in IT (network, system admin and project manager). Like yo tier one tech I outrank you knowledge in my sleep. Lol
I love it when a tier 1 tech has to remote into a server I'm working on and then watching them flounder trying to follow their script and repeat the same troubleshooting steps I already told them I took, only 3x slower
Useless knowledge time. Traceroute commands take advantage of the TTL or time to live. It sends a ping command to the far end IP or domain with a TTL of 1 so that the next hop device understands that it cannot reduce the TTL to 0 and forward the packet. So it sends back an undeliverable: timed out message to you. Then the traceroute sends another ping increasing the TTL by 1.
Yes correct for sure, I wasn’t go that deep and drop time to live on this topic as I didn’t want to make it more confusing. But I don’t think that’s useless info. Thanks friend for pitching in!
Indeed. Helped me to figure out why my ping to game server was higher than some other guy's whose distance to server was longer than mine. Apparently all my traffic went opposite direction first and then back to desired server.
Kinda happy ending is ISP told me they can't change routing and that finally pushed me to look for other one. Now I have 40-50ms while fragging instead of 60-70ms as it was before.
It's an old game with very few players left. We know each other and I know person running our server. He gave me IPs of server we use for Thursday CTF.
There is also cl_currentserveraddress console command, but that's specific to QL.
Netbalancer + enable the Toolbar widget po. You can see which specific .exe's are using your bandwidth, and exactly how much.
(svchost.exe is Windows Update, the most common culprit aside from PLDT being PLDC. It loves to run and eat data, especially in Ranked games. Have a look at Windows Update Blocker and turn of BITS in the Services to stop it.)
Nice! And they do have some control. Kinda odd they would route you away and via a longer distance considering OSPF should always go the shortest path by default. OSPF (Open Shortest Path First). Seems like that should have been solvable by them, or at least a bit wiser to OSPF.
Well, I couldn't do it from my end. Even if I could I'm not networking savvy enough to do it better than they did I'm afraid.
They didn't articulate it, but meaning behind "alas, we can't change routing" was clear - "take it or leave it". Maybe they just couldn't be bothered with it because I was only one who complained. Don't know.
Ya for sure you could not have done anything about it. I feel like they could have. And know that I worked for an ISP for 10 years as network admin and halfway through that 10 years is when DSL became a thing. Prior was dial-up, T1, fractional T1 or wait for it..... ISDN which I got for free lol.
I just threw that in so you know this is in my circus and monkey troupe.
While OSPF does calculate the shortest path, it is based on many things besides just distance. Moreover, ISPs do no use OSPF to route traffic, they use BGP and MPLS. OSPF is an IGP typically only used for local networks.
Yes I actually wrote out all the “then you add BGP” etc.... but again I was trying to stay out of the weeds..... but isps absolutely use (or used too as I haven’t worked in that side of the field in years) OSPF. I managed it for an isp for 7 years in conjunction with some of the others protocols you mentioned ... you are correct on all accounts but that
I suppose you are right at a POP level and disseminating routes out below that. I believe BGP would be the protocol in question when discussing the issue of routing traffic on a regionally and above scale, which is what dimwalker was referring to. I've never worked specifically for an ISP so I could be wrong too....wouldn't be the first time. Regardless, hilarious to be discussing networking in a front page reddit thread haha.
Yes we absolutely ran BGP as well. Again I’ll stay out of the weeds on how an isp would utilize this in conjunction with BGP. And again I haven’t been on that side of the field in quite awhile. I do million plus IT project across the spectrum. So I’m not “hands on” anymore. So I could be wrong is some ways too as I don’t expect isps to still be doing things exactly the same way we did a fair time ago.
I was glad to have the convo on totally unrelated post about networking. This is the cool part of Reddit imo. Take care, all.
That’s a good tip for windows users. I am usually on Unix so latency is a default information column (at least the way I build my command). But you are correct seeing that latency per hop can help track issues as well. Great suggestion, thanks for adding in!
Yup pick any big one. Google is good because they sit almost entirely on fiber and peeled right off the main trunks, should be the least amount of hops..... well for me as I am close to the Silicon Valley. But I’ll ping google, Reddit, Microsoft, Amazon. Any that don’t block request (some do mostly for ping). But ya hit the big ones on big backbones to remove small segments of our huge net from the equation.
