| 发明名称 | Network relay device and control method thereof | ||
| 摘要 | The network relay device is provided. The network relay device includes: a plurality of ports, each being configured to be connectable with one physical line; a virtual line controller configured to treat a plurality of physical lines, which are respectively connected with the plurality of ports, to constitute a virtual line; and a status check frame controller configured to send via the virtual line a status check frame for use in checking status of a network, which the network relay device is connected with via the virtual line, wherein the status check frame controller changes a frame-sending port to be used to send a next status check frame, in order to avoid continuously using an identical port as both a frame-sending port to send the status check frame and a frame-receiving port to receive the status check frame from another network relay device. | ||

| 主权项 | 1. A network relay device, comprising: a plurality of ports, each being configured to be connectable with one physical line; a virtual line controller configured to treat a plurality of physical lines as a virtual line, the plurality of physical lines are respectively connected with the plurality of ports; and a status check frame controller configured to send via the virtual line a status check frame for use in checking a status of a network, which the network relay device is connected with via the virtual line, wherein the network relay device forms a Ring network, the status check frame controller sends the status check frame from a port connected in a first direction of the Ring network and from a port connected in a second direction of the Ring network that is different from the first direction, and the status check frame controller changes a frame-sending port to be used to send a next status check frame, in order to avoid continuously using an identical port as both a frame-sending port to send the status check frame and a frame-receiving port to receive the status check frame from another network relay device. | ||
