[c-nsp] Inverse multiplexing of ATM (IMA)

[Richmond, Jeff (ELI)]

MLFR is definitely the way you want to go, as long as your equipment supports it. IMA has been around forever, but you pay the ATM cell tax, which is never fun. There is also IMA overhead for the ICP cells, but depending on your frame rate, it usually isn't too bad (less than 1% for 128, and up to 3.2% for 32. This is basically how often you send ICP cells, the shorter the number, the faster the convergence, but at the expense of the additional overhead). I am sure MLFR works the same way, but our current equipment doesn't support it, so I haven't played with it (yet)...

Good luck,
-Jeff

thanks for your aid.
 
I think that the multiLink frame relay is a good option.  
 
Sean, very good the Link.  it has helped me much.  
 
You would have some example with two frame relay and as it would be the necessary material?
 
 Sincerely yours.

	if you are already using frame relay, maybe multi-link frame relay is 
	an option ?
