[j-nsp] MTU Compression

[Robert J. Huey]

The motivation for this requirement is not all that clear and I suspect may have some bearing on a solution.    Is the backbone requirement because your forwarding on MPLS headers?  If so, I do not think that any of the MSS tweaks are going to help you.   Unfortunately, your third party circuit leaves you very little wiggle room, you might just be out of luck on that path.   Conversely, if the requirement is coming from the application side, you might consider a WAN Optimization Controller....     It's not a straight forward payload compression thing, but I think that they can operate in any point-to-point Ethernet environment and effectively proxy the TCP sessions locally.  that might get you bye.  good luck
