Method for Configuring Service Node, Service Node Pool Registrars, and System

A method, comprising:

• receiving a message of a first service node, wherein the message is a registration message or an update message or a deregistration message;
• forming a service node database in response to the message;
• receiving a service node query request sent by a management configuration device for the management configuration device to request a service node of a plurality of service nodes according to a service requirement, wherein the service node query request comprises the service requirement, wherein the service requirement is from a user or caused by a network change;
• searching, in response to the service node query request and according to the service requirement, the service node database to obtain service node information that matches the service node query request, and obtaining the service node information that matches the service node query request, wherein the service node information that matches the service node query request comprises one or more of:
• an identifier, location information, and status information of a service node that matches the service node query request, the service node that matches the service node query request being a second service node, the second service node being the first service node or another service node;
• and a service chain path that meets the service requirement;
• sending the service node information that matches the service node query request to the management configuration device for configuring the second service node according to the service node information that matches the service node query request.

A service node pool registrar, comprising:

• a transceiver, configured to:
• receive a message of a first service node, wherein the message is a registration message or an update message or a deregistration message;
• and
• receive a service node query request sent by a management configuration device for the management configuration device to request a service node of a plurality of service nodes according to a service requirement, wherein the service node query request comprises the service requirement, wherein the service requirement is from a user or caused by a network change;
• a processor;
• and
• a non-transitory memory storing program instructions executable by the processor, the program instructions including instructions to:
• form a service node database in response to the message;
• and
• search, in response to the service node query request and according to the service requirement, the service node database to obtain service node information that matches the service node query request, and obtain the service node information that matches the service node query request, wherein the service node information that matches the service node query request comprises one or more of:
• an identifier, location information, and status information of a service node that matches the service node query request, the service node that matches the service node query request being a second service node, the second service node being the first service node or another service node;
• and a service chain path that meets the service requirement;
• wherein the transceiver is further configured to send the service node information that matches the service node query request to the management configuration device for configuring the second service node according to the service node information that matches the service node query request.

A management configuration device, comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium storing a program executable by the processor, the program including instructions to:
• send, to a service node pool registrar, a service node query request to request a service node of a plurality of service nodes according to a service requirement, wherein the service node query request comprises the service requirement, wherein the service requirement is from a user or caused by a network change;
• receive, from the service node pool registrar in response to sending the service node query request, service node information that matches the service node query request, wherein the service node information that matches the service node query request comprises one or more of:
• an identifier, location information, and status information of a matching service node;
• and a service chain path that meets the service requirement;
• and
• perform network and service configuration on the matching service node according to the service node information that matches the service node query request.
