Each network processor of each DLC includes a fabric interface in communication with the fabric ports of that DLC. Each SFC includes at least one fabric element and SFC fabric ports. A fabric communication link connects each SFC fabric port to one DLC fabric port. Each fabric communication link includes cell-carrying lanes. Each fabric element of each SFC detects connectivity between each SFC fabric port of that SFC and one DLC fabric port over a fabric communication link. 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.

摘要： A switching network includes an upper tier having a master switch and a lower tier including a plurality of lower tier entities. The master switch, which has a plurality of ports each coupled to a respective lower tier entity, implements on each of the ports a plurality of virtual ports each corresponding to a respective one of a plurality of remote physical interfaces (RPIs) at the lower tier entity coupled to that port. Data traffic communicated between the master switch and RPIs is queued within virtual ports that correspond to the RPIs with which the data traffic is communicated. The master switch applies data handling to the data traffic in accordance with a control policy based at least upon the virtual port in which the data traffic is queued, such that the master switch applies different policies to data traffic queued to two virtual ports on the same port of the master switch.

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.
