Physical device 0, physical device 1, and physical device 2 are directly connected via an external physical channel (e.g., a network cable, an optical fiber, etc.). The slicing device 0 is interconnected with the upstream neighbor device through an x port, and the slicing device 1 is interconnected with the downstream physical device 1 through a y port. The slicing apparatus 2 is interconnected with the downstream physical apparatus 2 through a z-port. The slicing device 0 and the slicing devices 1 and 2 are interconnected through an internal logic channel.
Based on the system architecture shown in fig. 4, a device management method is further provided in the fourth embodiment, and fig. 5 is a flowchart of the device management method provided in the fourth embodiment of the present invention. As illustrated in fig. 5, the method includes:

In step 505, after collecting the information reported by the directly connected neighbor devices 1 and 2, the slicing device 0 reports the information to the upstream neighbor device through the port X.
Optionally, the upstream neighbor device may be directly a network management server, and the slice device 0 also reports physical information of the physical device 0, so that the network management server may form a neighbor topology relationship between the physical device 0 and the directly connected neighbor devices 1 and 2 according to the received information.

Similarly, the first slicing device is also responsible for collecting slicing device information (including a network address) in the physical device and reporting the slicing device information to the network manager, so that the network manager can obtain the logical device slicing information (including the network address) in the physical device, and the network manager can conveniently find and establish the corresponding affiliation relationship between the physical device and the logical slicing device, thereby facilitating management.

The port x of the physical device 0 and the upstream neighbor device (in this embodiment, the upstream neighbor device may be a network management server) are directly connected through an external physical channel (e.g., a network cable, an optical fiber, etc.). Wherein port y belongs to the slicing apparatus 1; port y 'belongs to the slicing apparatus 1'. Inside the physical device 0, the slicing device 0 is directly connected to the slicing device 1 through an internal logical channel 1, and the slicing device 0 is directly connected to the slicing device 2 through an internal logical channel 2. Inside the physical device 1, the slice 0 ' and the slice 1 ' are directly connected through an internal logical channel 1 '. Slice 0 ' and slice 2 ' are directly connected by an internal logical channel 2 '.
Optionally, in the physical device 0, only the slice device 0 resides in the DCN function, and the other slices do not reside in the DCN function; in the physical device 1, only the slice device 0' resides the DCN function, and the other slices do not.

Slice 0 'of the physical device 1 is responsible for managing and maintaining the automatic configuration or network management configuration of the physical ports x', y 'and z' in the DCN network. For example, the DCN function residing on slice device 0 is responsible for establishing management channels between network physical devices: the DCN function on the slicing device 0 automatically adds the ports x, y, z connected to the upstream and downstream physical devices into the DCN network, and automatically completes the L2, L3 network configuration, thereby getting through the channel from the slicing device to the network management server. The DCN function residing on the slicing device 0' is responsible for establishing management channels between the network physical devices: the DCN function on the slicing device 0 'automatically adds the ports x', y ', z' connected with the upstream and downstream physical devices into the DCN network, and automatically completes the L2, L3 network configuration, thereby getting through the channel from the slicing device to the network management server.

when the network manager needs to perform DCN configuration management on other slices in the physical device 0, the physical device 0 receives a DCN network management message of the slice of the physical device 0 and then sends the DCN network management message to the slice device 0, and the slice device 0 sends the DCN network configuration message to an internal target slice device 0;
when a network manager needs to perform DCN configuration management on a direct connection neighbor physical device 1 of a physical device 0, the physical device 0 receives a DCN network management message of the physical device 1 and then sends the message to a slicing device 0 for processing, the slicing device 0 receives the message and then sends the message to the direct connection neighbor physical device 1 through a physical port, when the direct connection neighbor device 1 receives the message, the message is sent to an internal slicing device 0 'for processing, and the slicing device 0' receives the message and then performs configuration management;

In addition, the DCN function residing in the slicing device 0 in the physical device 0 may also collect the slicing information inside the physical device 0; the information of the downstream equipment directly connected with the physical equipment 0 can be collected and reported to the network management server, so that the network topology management among the physical equipment and the affiliation relationship between the physical equipment and the logic slice equipment are formed and established in the network management server, and the network operation, maintenance and management are facilitated.
