Encryption - qazmlp wrote: Two nodes are connected in the same IP network. The average bandwidth of the IP link between those 2 nodes is 'T' MB/sec. These 2 nodes are 'D'(maybe, 200 or 300 km)km apart from each other. In that case, how much time it will take for transferring 'A' MB amount of data from one node to the other one? I am just confused about how the distance need to be considered for calculating this. Kindly clarify!Distance generally makes no difference. What does make a difference isthe capacity of the circuit between the two nodes (sometimes thecapacity can be dependant on distance, as is the case with aDSL, butin most cases it is NOT the case)The other thing that matters GREATLY is what protocol will be used totransfer "'A' MB of data" between the two nodes. And there aremultiple layers. At the physical and datalink layers, are you runningethernet over fiber, t1 circuits, or what? Frame Relay? ATM?Are these PT to PT connections, brigdged, routed in any way?And it gets even more diverse going up the layers toward theapplication layer -- Are you sending the data using NCP (netwarenative) or SMB (microsoft compatible) or NIS (unix protocol)? Are youusing TCP/IP? If so is it native or encapulated? If using IP, What MTU(packet size) is being used? What about recieve window size? Or areyou not using IP at all but IPX/SPX? How is that configured? Packetburst, etc.There are too many variables involved for there to be a simple answerto your question.
