System and Method for Enforcement of Service Level Agreements and Policies Across Geographical Domains

摘要

A service access gateway is described that provides enforcement of service level agreements across geographically remote domains. Each domain can comprise an access tier and a network tier that can be scaled by adding or removing server nodes. At the network tier level, a master node can be selected in each domain in order to maintain budget state information for the domain. Additionally, a global master can be elected in order to maintain the state information across multiple domains such that the service level agreements can be enforced in a synchronized manner. A geographical configuration service can also be implemented to generate alarms in cases where service level agreements across the multiple sites are not identical.
