The VM Turntable is structured around Xen-based Linux Virtual Machines that can be migrated in real time while still supporting live applications - transporting the whole set of memory pages and hard disk contents to various destinations. The live migration of Virtual Machines exploits a high degree of pipelining between the staggered operations of assembling the data to be transferred, verifying its integrity, and finally halting and transferring execution. To maintain lightpath security, the VM Turntable utilizes a token-based approach to efficiently enforce policies at both the bearer and control path levels (see the iGrid application "Token-based Network Element Access Control and Path Selection").
