Distributed service architecture based on a hierarchical load balancing approach

摘要

An Enhanced Service Layer Mapping which is hierarchical and widely load balanced to derive an efficiently distributed architecture. At the top of the hierarchy, all the ports are grouped into SPG units and tightly coupled with the SSS unit. At the second level of the hierarchy, within a given SPG-SSS unit, the ports and subscribers are sub-grouped and tied to a sub-pool of PEs. At an even lower level of the hierarchy, subscribers and services are mapped and load balanced to a fixed PEs.
