摘要： A slave device sends a first test signal via a downlink optical waveguide to a master device and recording a first transmission time, receives the first test signal looped back by the master device via the downlink optical waveguide and records a first reception time, and calculates a downlink delay time based on the first transmission and the first reception times. The slave device sends a second test signal via an uplink optical waveguide to the master device and records a second transmission time, receives the second test signal looped back by the master device via the uplink optical waveguide and records a second reception time, and calculates the uplink delay time based on the second transmission and the second reception times. Then, the slave device calculates a time offset between the master device and the slave device based on the downlink and the uplink delay times.

摘要： According to an example, an Edge Virtual Bridging (EVB) station is configured with a VM, an ER and multiple physical network cards. The VM is configured with multiple virtual network cards and each virtual network card has one VSI. Each VSI is connected with one of the physical network cards via the ER. One of the physical network cards is configured as a primary physical network card, and another is configured as a secondary physical network card. A VSI corresponding to the primary physical network card is configured as a primary virtual interface, and a VSI corresponding to the secondary physical network card is configured as a secondary virtual interface. After determining the primary physical network card failed, the secondary physical network card is configured as a new primary physical network card, and the secondary virtual is configured as a new primary virtual interface.

摘要： Examples of the present disclosure provide a method and an apparatus for synchronization after restart of a FC switch. For example, when a FC switch which is restarted detects that a neighbor FC switch has already established an adjacency relationship with the restarted FC switch, the adjacency relationship between the restarted FC switch and the neighbor FC switch is maintained, and the neighbor FC switch is requested to perform LSR initial synchronization to the restarted FC switch under a circumstance that the adjacency relationship is kept.

摘要： Examples of a SPB based multicast forwarding method are disclosed. Bridges in a SPBM network perform a multicast monitoring process, learn about multicast router and members of the IP multicast group, and notify other bridges in the SPBM network of the information through a SPB-ISIS LSP. A SPBM bridge in the SPBM network receives and parses the SPB-ISIS LSP, and configures the ingress and egress of the bridge, so as to guide the forwarding of IP multicast packets.
