    摘要: Methods and systems are provided for conducting maintenance such as software upgrades in components and nodes within a computer network while maintaining the functionality of the computer network in accordance with prescribed performance parameters. A balance is achieved between the rate of performing a desired system upgrade and the necessary performance parameters by empirically determining anticipated system loads and selecting the maximum number of components that can be upgraded simultaneously while meeting the anticipated loads. Provisions are made for the staggering of components through the upgrade process and for the return of components to active service in the computer network in response to unanticipated load spikes. Validation of successful upgrades is also provided.
