Hi all,

I need to calculate the Network bandwidth, disk space, processing power and memory of some messages that i exchanged between two computers (sender and receiver).

For example if the message is "I am working for three (3) hours"
How much network bandwidth will it use?
How much disk space will be used?
How much processing power will be utilize at the sender and the receiving end?
How much disk space will be used at both the ends?

if i will send this message 10, 100, or 1000 times.

Thanks for your guidance.

This depends on both programming language and implementation.

Let's assume you are writing code in pure C and sending a single message. If you are using UDP protocol and a short (up to kilobyte) ascii-coded message, then network bandwidth will be: message itself + packet header.

For TCP you must take into account connection establishment packets, possible retransmissions. For larger messages you must consider multiple packets, fragmentation, possible reordering lossess.

In general no disk space will be used, except for your program binary itself and libraries it uses. But if your programs or your system logs something on your packets... You got the idea.

CPU and memory utilization depends on both quality of your code and quality of your system libraries (as well as kernel and other libraries in use). No one can calculate this directly, but you may found this out experimentally on your own. For CPU utilization you may use oprofile and gprof coverage. For memory usage valgrind is your best friend.

I used perl sockets to exchange the messages between two computers. I need some solution which i can do it quickly. The tools you have mentioned needs a lot of work. I need some quick solution that can help me to calculte the rough usages.

Thanks.
