    摘要： A distributed system includes first-tier entities, and a master entity in communication with each first-tier entity. The master entity provides a single access point through which an administrator can submit commands to manage all entities. The master entity maintains a table of virtual slots. Each virtual slot points to one of the first-tier entities, and each first-tier entity is pointed to by at least one virtual slot. The processor runs an RPC (remote procedure call) client to submit RPC requests to the first-tier entities, and determines a destination first-tier entity for a given RPC request in response to which virtual slot the administrator submits a command. The distributed system can include second-tier entities, each indirectly communicating with the master entity through a first-tier entity. The table has a virtual slot for each second-tier entity, which points to the first-tier entity acting as proxy for the second-tier entity.

    摘要： A distributed fabric system comprises a plurality of independent network elements interconnected by inter-switch links and assigned to a same group. Each network element includes a switching chip, a processor, and memory storing program code that is executed by the processor. The program code of each network element includes a device configuration (DC) stacking module and a switch discovery protocol (SDP) module. The SDP module of each network element, when executed, discovers each other network element in the group and elects one of the network elements as a master network element. The SDP module of the master network element, when executed, sends messages to the DC-stacking module of the master network element. Each sent message identifies one of the network elements in the group. The DC stacking module of the master network element, when executed, maintains a record of all network elements that are currently members in the group.

Each SFC includes program code that reads connectivity matrix from fabric element chips and sends connection information corresponding to the detected connectivity from that SFC to a central agent. A network element includes the central agent, which, when executed, constructs a topology of the distributed fabric system from the connection information sent from each SFC.
