Abstract
Improving the multi-site software update for extension switches by automatically assigning extension switches at each data center with a role and then providing state messages between the extension switches to stage software update operations between the various extension switches that are involved. This allows the network administrator to commence the software update process on the extension switches at each data center without waiting for any extension switch to complete operations. The extension switches communicate with each other and the software update process completes automatically, with all extension switches at all data centers updated without further network administrator input.
