Automated migration of port profile for multi-level switches

The use of virtualization technology has been increasing in the data center to consolidate physical servers into virtual machines and allocate computing resources dynamically by moving virtual machines. IEEE 802.1 Data Center Bridging Task Group is developing a standard to reduce complexity of the network management and automate a task to move network state in an adjacent bridge along with the migration of a virtual machine, which is called Automated Migration of Port Profile (AMPP). However AMPP works between a server and an adjacent bridge only. We propose an extension of AMPP for multi-level switches to further reduce complexity and automate the task. We developed a prototype of the extension and confirmed a network state is moved in a multi-level switch configuration using the standard protocol as it is on the wire. This paper describes IEEE standard based AMPP, our proposed extension of AMPP for multi-level switches, and a prototype of the extension.
