Abstract: A network relay device relays data in a layer 2 network. The network relay device includes first and second communication ports, a snooping module, a transfer information storage unit, a multicast sending module, a failure detector and a port adding module. The snooping module generates snooping information. The snooping information correlates the first communication port set to a multicast transfer port to a destination MAC address. The multicast sending module refers to the snooping information stored in the transfer information storage unit and sends a multicast frame received from the layer 2 network, from the correlated multicast transfer port. The failure detector detects a communication failure in the layer 2 network. The port adding module additionally, in response to detection of the communication failure by the failure detector, set the second communication port, in addition to the first communication port, to the multicast transfer port.

Abstract: In a virtual network apparatus, even when a fault occurs on a private line connecting plural physical network apparatuses to communicate a control signal, the redundancy is maintained, and the lower forwarding capability is prevented. In this network system, a control signal for virtualization to be transmitted and received between plural physical network apparatuses is relayed via a unit spanning LA connecting each physical network apparatus and an adjacent network apparatus in the adjacent network apparatus. Thereby, even when a fault occurs in the private line, it is possible to continue to communicate the control signal between the physical network apparatuses and continuously operate the virtual network apparatus.

Abstract translation: 在虚拟网络装置中，即使在连接多个物理网络装置的专用线上发生故障来通信控制信号的情况下，也能够维持冗余，能够防止较低的转发能力。 在该网络系统中，在多个物理网络装置之间发送和接收用于虚拟化的控制信号经由连接每个物理网络装置的单元和相邻网络装置中的相邻网络装置进行中继。 因此，即使专用线路发生故障，也可以继续在物理网络装置之间通信控制信号，并连续运行虚拟网络装置。
