Abstract

A method for configuring a service node, a service node pool registrar, and a system are provided. The service node pool registrar receives a service node query request sent by a management configuration device, where the service node query request includes a service requirement, where the service requirement is from a user or caused by a network change; the service node pool registrar searches a service node database to obtain service node information that matches the service node query request and sends the matching service node information to the management configuration device, so that the management configuration device performs network and service configuration on the matching service node according to obtained network topology information and the matching service node information.

First claim

What is claimed is:

1 . A method for configuring a service node, comprising:
receiving a service node query request sent by a management configuration device, wherein the service node query request comprises a service requirement, wherein the service requirement is from a user or caused by a network change; searching a service node database, to obtain service node information that matches the service node query request, wherein the matching service node information comprises one or more of the following: an identifier, location information, status information of a matching service node, a selection policy for the status information, a tenant identifier, and a service chain path that meets the service requirement; and sending the matching service node information to the management configuration device, so that the management configuration device performs network and service configuration on the matching service node according to obtained network topology information and the matching service node information.

2 . The method according to claim 1 , wherein the receiving a service node query request sent by a management configuration device comprises:
receiving, by extending a protocol message of the Aggregate Server Access Protocol (ASAP) or defining a new message, the service node query request sent by the management configuration device.

3 . The method according to claim 1 , wherein the method further comprises:
receiving a registration message or an update message or a deregistration message of the service node, to form a service node database.

4 . The method according to claim 3 , wherein
the registration message or the update message or the deregistration message of the service node is received by extending a protocol message of the Aggregate Server Access Protocol (ASAP) or defining a new message, to form the service node database.

5 . The method according to claim 3 , wherein the method further comprises:
performing keep-alive detection on a service node that has registered, monitoring a status of the service node that has registered, and performing troubleshooting.

6 . The method according to claim 3 , wherein the method further comprises:
synchronizing the registration message or the update message or the deregistration message of the service node with the management configuration device.

7 . The method according to claim 6 , wherein
the registration message or the update message or the deregistration message of the service node is synchronized with the management configuration device by extending a protocol message of the Aggregate Server Access Protocol (ASAP) or defining a new message.

8 . The method according to claim 1 , wherein the service node query request is relocation of the service node, and the method further comprises:
receiving the service node query request sent by the management configuration device, wherein the service node query request comprises a constraint of relocation of the service node; searching the service node database, to obtain the service node information that matches the service node query request, wherein the matching service node information comprises an identifier and location information of a source node that meets the constraint and an identifier and location information of a destination node that meets the constraint; and sending the matching service node information to the management configuration device, so that the management configuration device instructs, according to the obtained network topology information and the matching service node information, the matching source node to perform a deregistration operation, and activates and enables the matching destination node to serve the user.

9 . A service node pool registrar, comprising:
the transceiver, configured to receive a service node query request sent by a management configuration device, wherein the service node query request comprises a service requirement, wherein the service requirement is from a user or caused by a network change; the processor; and a memory, configured to store program instructions, the processor to execute the program instructions to: searching a service node database, to obtain service node information that matches the service node query request, wherein the matching service node information comprises one or more of the following: an identifier, location information, and status information that are of a matching service node, a selection policy for the status information, a tenant identifier, and a service chain path that meets the service requirement; wherein the transceiver is further configured to send the matching service node information to the management configuration device, so that the management configuration device performs network and service configuration on the matching service node according to obtained network topology information and the matching service node information.

10 . The service node pool registrar according to claim 9 , wherein the transceiver is configured to receive, by extending a protocol message of the Aggregate Server Access Protocol (ASAP) or defining a new message, the service node query request sent by the management configuration device.

11 . The service node pool registrar according to claim 9 , wherein the transceiver is further configured to receive a registration message or an update message or a deregistration message of the service node, to form a service node database.

12 . The service node pool registrar according to claim 11 , wherein the transceiver is configured to receive the registration message or the update message or the deregistration message of the service node by extending a protocol message of the Aggregate Server Access Protocol (ASAP) or defining a new message, to form the service node database.

13 . The service node pool registrar according to claim 11 , wherein the processor is further configured to execute the program instructions to perform keep-alive detection on a service node that has registered, monitor a status of the service node that has registered, and perform troubleshooting.

14 . The service node pool registrar according to claim 11 , wherein the processor is further configured to execute the program instructions to synchronize the registration message or the update message or the deregistration message of the service node with the management configuration device.

15 . The service node pool registrar according to claim 14 , wherein the processor is configured to execute the program instructions to synchronize the registration message or the update message or the deregistration message of the service node with the management configuration device by extending a protocol message of the Aggregate Server Access Protocol (ASAP) or defining a new message.

16 . The service node pool registrar according to claim 9 , wherein:
the service node query request is relocation of the service node, and comprises a constraint of relocation of the service node; and the matching service node information comprises an identifier and location information of a source node that meets the constraint and an identifier and location information of a destination node that meets the constraint.
