ProMemoreX Posted October 31, 2005 Report Posted October 31, 2005 Hi, I have high packet loss in SSCU Red Star. It doesn't happen all the time but it happens every few hours for 30 minutes. I have a DSL connection. (1.5 down; 384 up) trace.txt
»SOS Posted October 31, 2005 Report Posted October 31, 2005 Well, trace looks fine. Try calling your ISP and having them check the line (and hope they check it at a moment when it is going bad). I assume you have tried with all other programs off? And downloading programs off too?
ProMemoreX Posted October 31, 2005 Author Report Posted October 31, 2005 Well, I am using a router and I have 3 PCs connected. I have no downloading programs but have msn/aim on. I'll try calling my isp and see what they say.
»SOS Posted November 1, 2005 Report Posted November 1, 2005 You could try without the router as well, if the possibility exists to connect the internet directly to your computer. Or try it without the other computers for a few hours.
»Maverick Posted November 1, 2005 Report Posted November 1, 2005 The trace shows that it isn't a problem with your computer(s) or your router. The problem is located at a router/switch near the server, something you can't do anything about. I suggest waiting until the problem resolves, there is not alot more you can do.
»SOS Posted November 1, 2005 Report Posted November 1, 2005 Sorry, Mav, that's incorrect. The trace shows that everything is in perfect working order, really.As I have said several times on this board, the only hop that matters is the last one. And this 1% can be discarded as measurement inaccuracy. So, everything looks fine.
»Maverick Posted November 1, 2005 Report Posted November 1, 2005 As I have said several times on this board, the only hop that matters is the last one.Why so? A trace is a graph that displays the response time (and packet loss %) per hop, right? If response time and/or packets is longer/gets lost at the X hop, that would show a problem with that hop, correct?What I see at the trace from ProMemoreX, packets gets lost at the 14th hop which would explain his problem. However its weird the packetloss is gone at the last hop, however what is the reason behind the packetloss at the 14th then?
»SOS Posted November 1, 2005 Report Posted November 1, 2005 Crappy routers Which is exactly why its not weird that it dissappears at the last hop Maybe I should explain? Bah, I'm tired. Just take my word for it Maybe in the morning... almost midnight here... reply if you still don't get it
»Maverick Posted November 1, 2005 Report Posted November 1, 2005 hehe ok, I will await your explenation since I am quite curious to the reason behind your explenation
ProMemoreX Posted November 2, 2005 Author Report Posted November 2, 2005 Lol.. I dont think I have a crappy router.. I have a Linksys D-624 and updated to the latest firmware. It is a wireless router but I only use the wired part of it.
»SOS Posted November 2, 2005 Report Posted November 2, 2005 No, I meant some other routers were crappy on the net, not yours Anyway, what happens is that the router with the big loss gets a ping (=trace) packet. Now, it sees that the ping packet is meant to itself. It figures "WTF? I ain't no host! Stupid annoying kids... this could even be some freaky D®DOS. Psh!" and just drops it. (It actually seems to reply to the packet but only once (that's why its not 100% loss), it ignores any repeated packets) But when it sees that the packet is not meant for itself, it lets it through, which is why hops after the annoying routers are fine.
