US Patent 7548545 Disaggregated network management

Systems and methods for disaggregated management of a network fabric are presented. Network elements composing the network fabric can operate as a fabric manager with respect to one or more management functions while also continuing to operate as a communication conduit among hosts using the fabric. The roles or responsibilities of a fabric manager can migrate from one network element to another to preserve management coherency as well as to secure management of the network. Additionally, fabric managers communicate with the network fabric through one or more management channels.
