摘要： A network fabric includes interconnected network nodes, each having access to a database containing predetermined paths from each network node to each other network node in the network fabric. Each network node determines, in response to an incoming frame, whether the frame is a fabric protocol data unit (PDU) having a header containing path attributes including a destination node address. If the frame is a fabric PDU, the node selects a first path to the destination node from the database, and forwards the fabric PDU to a next hop in accordance with the selected path. If the frame is not a fabric PDU, the node selects a second path through the network fabric to the destination node from the database, adds the header with the path attributes to the frame to produce the fabric PDU, and forwards the fabric PDU to the next hop in accordance with the second path.

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.

摘要： A scaled-out fabric coupler (SFC) chassis includes a plurality of root fabric cards installed on the one side of the SFC chassis. Each root fabric card has a plurality of electrical connectors. A plurality of line cards is installed on the opposite side of the SFC chassis. Each line card is one of two types of line cards. One of the two types of line cards is a switch-based network line card having network ports for connecting to servers and switches. The other of the two types of line cards is a leaf fabric card having fabric ports for connecting to a fabric port of a network element. Each of the two types of the line cards has electrical connectors that mate with one electrical connector of each root fabric card installed in the chassis.

Each network element includes one or more switching chips, a processor, and memory storing program code that is executed by the processor. The program code of each network element includes a switch discovery protocol (SDP) module. The SDP module of each network element, when executed, periodically multicasts SDP data units (SDPDUs) using one of a plurality of transmission rates. The plurality of transmission rates includes a fast transmission rate and a slow transmission rate. The transmission rate used by the SDP module of each network element is the fast transmission rate until the SDP module of that network element determines a criterion is met, in response to which the transmission rate used by the SDP module of that network element changes to the slow transmission rate.
