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 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.

摘要： A technique for securing a virtualized computing environment includes retrieving identification information from a packet received on a physical port of a network switch. Port assignment data (maintained by one of a virtual machine monitor and a virtual machine monitor management station) for a virtual machine identified in the received packet is retrieved. The identification information from the received packet is compared with the port assignment data to determine whether the virtual machine is assigned to the port. In response to determining that the virtual machine is assigned to the port, the packet is forwarded to a destination designated in the packet. In response to determining that the virtual machine is not assigned to the port, the packet is blocked.
