Does LAN speed distributes among connected terminals on load
Hi All, I have a 100Mbps LAN with 10 connected terminals through a Switch. Now, I understand 100Mbps is the max speed at which a terminal can send/receive data. If every terminal sends data at this speed, then does this speed distributes/divides according to load, or is it dedicated for each terminal. How to measure it? -- Manavendra Nath Manav

It's rather a generic question... let me try to begin to answer it. First of all, the speed of the link is 100mbps wire speed. There is a lot of overhead caused by different protocols (I redirect you to learn about the OSI or TCP/IP stacks and about encapsulations). So the speed is way lower than 100 when doing anything over the network. Now, the question about if the speed is shared is hard to answer. The straight forward answer is no. Traffic would be shared if the network would be connected via a hub ( I doubt hubs are actually used in modern networks). Switches are 'smart' so they don't push traffic in parts of the network where is not needed, so, theoretically, the bandwidth is not share. However, most of the traffic we have in a network is not inside our Local Area Network, but with the Internet and all that traffic passes through the gateway. So the gateway would be the bottleneck and the traffic is 'distributed' among the hosts in the network. This is a very brief answer to what you said... maybe if you could provide some further details on what exactly you want to do, you will receive a better answer. -- Alexandru Juncu ROSEdu http://rosedu.org

Hi Alexandru, Thanks for the detailed answer. In my 100Mbps LAN setup, I have several clients/terminals connected to a server. The problem is that the server is connected to the LAN via a GPRS module whose bandwidth is very less (128kbps). So, different clients are parallely sending data to server but most are getting timed-out because of bandwidth constraints. My question is how I can verify that packets are being dropped/timed-out because of bandwidth at the GPRS interface? Is there any tool to do this? -- Manavendra Nath Manav
