The

steps

501 and 503 are not in front-back order, and the step numbers are only for convenience of distinguishing the steps.

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.

The

steps

505 and 508 are not in front-back order, and the step numbers are only used for convenience of distinguishing the steps.

Optionally, the upstream neighbor device may be directly a network management server, and the slicing device 0 also reports its own information, so that the network management server may form a corresponding attribution relationship between the physical device 0 and the slicing devices 0, 1, and 2 according to the received information. When the upstream neighbor device is not the network management server, the slicing device 0 may report the collected information to the upstream neighbor device, and report the collected information to the network management server through the upstream neighbor device.

When a new physical device with a slicing device joins a network, in order to facilitate a network management server to timely master the topological relation and internal slicing information of the new physical device, the slicing of the new physical device also needs to be responsible for notifying downstream neighbor device information and internal slicing information of the new physical device to an upstream direct-connected neighbor device, and after the upstream neighbor device discovers the newly joined connected device, the upstream neighbor device notifies the received device and slicing information reported by the new physical device to the network management server, so that the network management server can master the topological relation and internal slicing device information of the newly joined physical device, thereby facilitating the configuration and management of the slicing device in the new physical device by the network management server.

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.

EXAMPLE five

In the fifth embodiment of the present invention, after one physical device is divided or configured into a plurality of slice devices, only one slice device resides in the DCN function, and other slice devices do not reside in the DCN function, and the slice devices in one physical device are directly connected through an internal logical channel.

Fig. 6 is a schematic structural diagram of a system for device management according to a fifth embodiment of the present invention. As shown in fig. 6:

in this fifth embodiment, the physical device 0 is divided into 3 slicing devices: slicing apparatus 0, slicing apparatus 1, and slicing apparatus 2. Physical device 1, also divided into 3 slicing devices: slicing apparatus 0 ', slicing apparatus 1 ', slicing apparatus 2 '.

Port y of physical device 0 and port y' of physical device 1 are directly connected by an external physical channel (e.g., a network cable, an optical fiber, etc.). 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. When the physical device 0 and the physical device 1 are started, the physical ports x, y, z, x ', y ' and z ' are automatically added into the DCN network. The slice device 0 of the physical device 0 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. 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.

Based on the system architecture shown in fig. 6 and the fourth embodiment, the fifth embodiment further provides a device management method, and fig. 7 is a flowchart of the device management method provided in the fifth embodiment of the present invention. As illustrated in fig. 7, the method includes:

step 701, when the slice device 0' in the downstream physical device 1 cannot be accessed in the DCN network, the network management server sends a configuration management message to the slice device 0;

before the network management server executes step 701, the network management server has already obtained the network topology relationship and the internal slice information of the physical devices 0 and 1, so that the network management server has already known that the physical device 0 is an upstream neighbor device directly connected to the physical device 1, and the slice device 0 in the physical device 0 has already joined in the DCN network.

Step 702, after receiving the configuration management packet, the slice device 0 sends the configuration management packet to the physical device 1 through an external physical channel between the physical device 0 and the physical device 1;

step 703, after receiving the configuration management packet, the physical device 1 forwards the configuration management packet to the slicing device 0';

step 704, the DCN function in the slicing device 0' performs configuration management according to the received configuration management message.

The DCN module is responsible for completing configuration management of the physical device 1 according to the configuration management packet, for example, when the configuration management packet is a DCN configuration packet, the L2 or L3 layer network configuration is performed on the physical port y 'connected to the upstream physical device, or related route configuration is performed, so as to open a channel from the slicing device 0' to the network management server.

When the network management device needs to perform configuration management on the physical device 0 or 1, the configuration management message sent by the network management device is delivered to the first slicing device (for example, the slicing device 0 or the slicing device 0' in this embodiment), and the configuration management processing on the physical devices 0 and 1 is completed. If the network manager wants to perform configuration management on the slice device inside the physical device 0 or 1, the configuration management message of the network manager is sent to a first slice device (for example, the slice device 0 or the slice device 0' in this embodiment), and when the target device of the configuration management message is the first slice device, the first slice device performs configuration management according to the configuration management message; when the target device of the configuration management message is other slicing devices except the first slicing device, the first slicing device delivers the configuration management message to the target slicing device through an internal logic channel, so that the configuration management of the target slice is completed.

Specifically, when the network manager cannot directly access the slicing device in the physical device 0 or the slicing device in the downstream neighbor physical device 1 or the physical device 1, the configuration management message sent by the network manager may be uniformly received from the port x through the physical device 0, and then corresponding operations are performed according to the difference of the target slicing devices. The configuration management message includes one of the following:

configuration management message of physical device 0,

DCN network management message of physical device 0,

Configuration management message of 0 slice of physical device,

DCN network management message of physical device 0 slice,

Configuration management messages of the physical device 1,

DCN network management message of the physical device 1,

Configuration management message of physical device 1 slice,

DCN network management messages for physical device 1 slice.

Optionally, the method further comprises:

when the physical device 0 receives the configuration management message of the physical device 0, the configuration management message is delivered to the slicing device 0 for configuration management;

when receiving the configuration management message of the slice of the physical device 0, the physical device 0 delivers the configuration management message to the slice device 0 for processing, and the slice 0 is delivered to a target slice device in the physical device 0 through an internal logic channel for operation;

when the physical device 0 receives the configuration management message of the physical device 1, the message is delivered to the slicing device 0, then the slicing device 0 sends the message to the neighbor physical device 1 through a physical port directly connected with the neighbor, and after the neighbor physical device 1 receives the message, the slicing device 0' delivered to the physical device 1 is processed;

when receiving the configuration management message of the slice of the physical device 1, the physical device 0 delivers the configuration management message to the slice device 0, then the slice device 0 sends the message to the neighbor physical device 1 through a physical port directly connected with the neighbor, after receiving the message, the neighbor physical device 1 processes the slice device 0 'delivered to the physical device 1, and then the slice device 0' sends the message to a target slice device in the physical device 1 through an internal logic channel for processing.

in the sixth embodiment, the physical device 0 is divided into 4 slicing devices: slicing device 1, slicing device 2, slicing device 3 and slicing device 4.

Ports 1, 2, 3 of physical device 0 are attributed to slicing device 1, ports 4, 5, 6 are attributed to slicing device 2, ports 7, 8, 9 are attributed to slicing device 3, and ports 10, 11, 12 are attributed to slicing device 4. The slicing devices are interconnected through logic channels.

Specifically, when each physical port receives a DCN configuration management message sent by a network manager, the DCN configuration management message can be directly delivered to the slice device to which the physical port belongs. For example, in the sixth embodiment, when the network manager sends the DCN configuration management packet to the slicing device 1 through the DCN network, the DCN configuration management packet may be directly delivered to the slicing device 1 through the physical port 1.
