Claim Text:
1. A method, comprising: dividing a control plane of a storage area network (SAN) into a centralized network control plane and a plurality of decentralized control planes, wherein the control plane comprises a logical division of network architecture that carries signaling and management traffic instead of data traffic, wherein a plurality of switch level SAN applications are accessed through the decentralized control planes, the switch level SAN applications basing network connectivity computations at a link-level that changes from point to point within the SAN; configuring at least one network-wide SAN application in the centralized network control plane, wherein the network-wide SAN application bases network connectivity computations at a network level that remains the same from point to point across the SAN; and configuring at least one switch-level SAN application in the decentralized control planes.
