  • Flow based dynamic load balancing for cost effective switching systems
    Patent number: 7292589
    Abstract: An apparatus and method for a load balancing system that is resident in line card sub-systems, service processing card sub-systems or other sub-systems of network devices such as routers. In various embodiments of the invention, the load balancing system considers factors in some key system parameters, other than merely internal fabric port speeds, to optimize its mode of operation.

  • Distributed service architecture based on a hierarchical load balancing approach
    Publication number: 20040071141
    Abstract: 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.
