I'm working on load in mobile networks (GSM,TDMA,3G) emulating WAP and HTTP protocols.
Part of load model are network parameters as latency, packet loss, web server response, end-2-end response. I would like to know if there are some common values for those parameters, may be for each network type. For example latency 300 msec and 3% packet loss for network x.. How can I estimate those parameters (I have no opportunity to receive the information from provider)? Maybe you familiar with some formula, if i know the bandwidth, amount of concurrent sessions..etc.
And what kind of parameters it important to integrate in order to emulate the real mobile network? Kind of packets disordering etc..
Thanks in advance.
We use a tool from Shunra to do network simulation. It allows you to take a snapshot of production (latency, packet loss, congestion, link size) and apply these characteristics to a network. The tool used to be called The Storm, but now it is called "Virtual Enterprise".
I don't think anyone can really provide you "common values" for this information, as it is pretty specific to the environment. The nice thing with this tool is that you can capture this information for YOUR environment.
