We want high speed internet access. We have multiple internet
connections to a single pc. All of them have slow speed.

We have software which require high speed internet. But it costs very
dearly in our country. So we have no option but to rely on slower
connections.

We can connect to any number of internet connections on the pc. But
the problem is that pc gives access to only one connection to a
software.

Now we want a solution where we connect to 2-4 internet connections
and ny software can get higher speed by accessing all of them at the
same time.

This can be expalined like this, we have 2 internet connections. We
have a software which runs 10 parallel connections to find something.
Now it should make 5 connections through each internet connection.

This should also allow other computers in local loop to access both
connections for higher speeds.

If you don't understand anything please get back to us.

My connections need authentication, so use of any external device is not possible. 

As computer based application/utility is required for load balancing.

Ashish,

Many ways exist to do this, first let me know:
1) Your existing internet connection type (i.e. dial up, DSL, lease line etc)
2) Your desried server platform where it is going to be Windows based
or Linux based
Once I have this information, I can comment back.

well there is a way to bridge connections using windows XP if u have
it it.that makes integrating connections soo much easier

The easiest way is to use a third party load balancing product. F5
offer a 'cut down' version of a BigIP - which they market as a 'link
controller' which will load balance two connections perfectly.

I'm not affiliated with F5, other than the fact that we use their
products at work... they are _very_ good.

What's your software's protocal? HTTP? TCP/IP? or lower level protocal?

Maybe you could try WinGate (a software)
