Embodiment Construction

[0024] refer to figure 1 , shows a network showing parts according to the invention. A first data center 700 is shown with three separate internal networks, a TRILL network 702 , a normal Ethernet Spanning Tree Protocol (STP) network 704 and a storage area network (SAN) 706 . Application server 708 is connected to TRILL network 702 , while application server 710 is connected to STP network 704 and SAN 706 . Storage 712 is shown connected to SAN 706 . Each of networks 702 , 704 , and 706 has converged network extension (CNE) devices 714 , 716 , 718 connected. CNE devices 714 , 716 , 718 are connected to routers, which in turn are connected to WAN 722 . The second data center 750 is similar, with a VCS Ethernet fabric network 752 and a SAN 754 . Application servers 756 are connected to each network 752 and 754 and storage is connected to SAN 754 . CNE devices 760, 762 are connected to each network 752, 754 and router 764, which is also connected to WAN 722 to allow data cen...
