Patent ID: 11818038

Abstract:
Techniques for initiator-based data-plane validation of segment routed, multiprotocol label switched (MPLS) networks are described herein. In examples, an initiating node may determine to validate data-plane connectivity associated with a network path of the MPLS network. The initiating node may store validation data in a local memory of the initiating node. In examples, the initiating node may send a probe message that includes a request for identification data associated with a terminating node. The terminating node may send a probe reply message that includes the identification data, as well as, in some examples, a code that instructs the initiating node to perform validation. In examples, the initiating node may use the validation data stored in memory to compare to the identification data received from the terminating node to validate data-plane connectivity. In some examples, the initiating node may indicate a positive or negative response after performing the validation.
