Red represents Internet-2 traffic. Blue represents Internet-1 traffic. Traffic in the USA is tagged on Cisco #1 with MPLS, depending if the data came via the red path or blue path. The red path has the data travel via a satellite accelerator box which will allow faster than 1Mb/sec TCP streams. Packets travelling on the high-speed international link will have MPLS headers. On Cisco #3 the MPLS headers will be stripped and the packets will continue on their journey via either the red or blue path depending if it I1 or I2 traffic.
