[0037] Step 4: Provide a visual interface for instance management and status monitoring.

[0038] Among them, the SID rule configuration includes a rule name, number of digits, and semantic definition.

[0046] Example interface:

[0047]

[0048] 2. Generate an SFC instance and bind it to the SID.

[0049] When creating an SFC instance, the effective SID rules are used by default to generate a SID list (such as AFA1:0200::0000:0000).

[0050] Bind the application to the SID rules, and associate the head node gateway (the SRv6 gateway directly connected to the application) and the tail node gateway.

[0051] Example interfaces:

[0052]

[0053] 3. Download the configuration to the SRv6 gateway.

[0054] Push the SID list to the head node and tail node gateways through the southbound interface, and set static routes and policies.
