down ping in a ISP - Page 2

post #11 of 18
First get the definitions straight.
Latency or better yet "Round-trip" the one-way latency from source to destination plus the one-way latency from the destination back to the source. When you send a ping to a server, it sends the packet to the server then you wait for a response. In the case of Ping you are waiting for a echo-reply.

Bandwidth is a rate of data transfer, bit rate or throughput, measured in bits per second.

Latency can be affected by bandwidth, traffic congestion, and number of hops (aka devices, routers and switches) before reaching the destination.

Now the OP is asking about his ISP, where as it appears he is asking more about a specific site he is trying to reach i.e. Overclock.net which is a website not his ISP. He could have as many as 20+ hops before reaching OCN.

Depending on where the OP is in the world, latency and speeds are dramatically affected by the Local LEC.

Or, just use traceroute as it's already a part of your OS..

"Bandwidth", or throughput .. is how many megabits per second you can get.
Bandwidth is the frequency of the medium you're using
Latency/ping is response times.

My connection in my apartment has HORRIBLE speed, I get about 100kbps download. Yet, I can game fine because I have excellent ping.

oh scrap its ping not server load Thx got mix up.

don't think isps have control over ping. There's factors beyond they're control influencing it. From a client side. Ill think about a tunnel to a server. Java one or something like fpipe.

lol thought he was talking about server load coz he asked how a server can improve a ping but I notice its ISP he just used the server as a isp example

exactly...!

I have hope that my ISP improve its service by implementing best features, backbones, decrease the amount of hops ...

Your ISP is going to implement whatever solution is the cheapest that vaguely meets the guidelines as specified..

This is how I understand it. So ^can just say if its wrong or not but every network link has a maximum packet size called the link's MTU. Now the full path may travel from one computer to another may travel across many links with different MTUs. The smallest MTU for all the links in a path is the path MTU . Now if the packet gets on a network with a smaller MTU it may too big too fit. Now I know unless it changed the sending system needs permission from the receiving system to send a bigger packet. But that permission is almost given as a routine these days.

Now a connection over the Internet actually depends on two routes. The route from your system to the server, and the route from that server back to your system. These routes may be and often are completely different. If they differ, a problem in your connection could be a problem with either the route to the server, or with the route back from the server. A problem in a traceroute may actually not be with the system in your trace it may rather be with some other system on the reverse route back from the system that looks, from the trace, to be the cause of the problem.
So a traceroute from you to the server is only showing you half of the picture.

In the good oll days you could use source routing with traceroute to see the reverse trace back to you from a host. But coz of abuse most network admin block source routing. Now if you run a trace route and you see one long hop or a time increase between one place to another might means its crossing a ocean, a router that's overloaded, some flimsy country network etc etc. So its out of your isps hands and control. You can ping a server next door or close to you the ping time will be low but then you can ping a server on another continent which means your ping time will increase.

If you see these in a trace route ->10.*
*.172.[16-31].*
192.168.* and they are not in your own network then it could mess up a connection or a ping to a target. I know a lot of companies in the US like do it with their servers dunno why they say its security dunno.
