Abstract
A method to perform operations, administrative, and maintenance (OAM) includes a controller generating a policy configuration packet, where the policy configuration packet includes OAM configuration information and information about a first path, and the information about the first path is used to identify the first path. The controller sends the policy configuration packet to a head node of the first path, where the policy configuration packet is used to indicate the head node to perform OAM on the first path based on the OAM configuration information.
Claims20
A controller comprising:
- one or more memories configured to store programming instructions;
- and
- at least one processor coupled to the one or more memories and configured to execute the programming instructions to cause the controller to:
- generate a segment routing (SR) policy configuration packet, wherein the SR policy configuration packet comprises in-situ flow information telemetry (iFIT) configuration information, first information about a candidate path, and identification information, wherein the candidate path comprises a plurality of segments, and wherein the identification information instructs a head node of the candidate path to perform, based on the iFIT configuration information, iFIT on the candidate path comprising the plurality of segments when the candidate path is an active path;
- and
- send the SR policy configuration packet to the head node.
A network device comprising:
- one or more memories configured to store programming instructions;
- and
- at least one processor coupled to the one or more memories and configured to execute the programming instructions to cause the network device to:
- receive a segment routing (SR) policy configuration packet, wherein the SR policy configuration packet comprises in-situ flow information telemetry (iFIT) configuration information, first information about a candidate path, and identification information, wherein the candidate path comprises a plurality of segments, and wherein the identification information instructs a head node of the candidate path to perform, based on the iFIT configuration information, iFIT on the candidate path comprising the plurality of segments when the candidate path is an active path;
- and
- perform, based on the iFIT configuration information, iFIT on the candidate path comprising the plurality of segments when the candidate path is the active path.
A system comprising:
- a controller configured to:
- generate a segment routing (SR) policy configuration packet, wherein the SR policy configuration packet comprises in-situ flow information telemetry (iFIT) configuration information, first information about a candidate path, and identification information, wherein the candidate path comprises a plurality of segments, and wherein the identification information instructs a head node of the candidate path to perform, based on the iFIT configuration information, iFIT on the candidate path comprising the plurality of segments when the candidate path is an active path;
- and
- send the SR policy configuration packet to the head node of the candidate path;
- and
- the head node configured to:
- receive the SR policy configuration packet;
- and
- perform, based on the iFIT configuration information, iFIT on the candidate path comprising the plurality of segments when the candidate path is the active path.
