Application programming interface (API)-based multi-tenant routing control plane

A system comprising:

• a first network domain of a multi-domain network including at least:
• a first router that updates network configurations for the first network domain;
• an application programming interface (API) server;
• and
• a datastore that stores current network configurations for the first network domain;
• one or more processors;
• and
• one or more computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• receiving, at the API server, a first API request;
• determining, at the API server, that the first API request corresponds to performance of an operation with respect to at least the first network domain;
• determining, at the API server and based at least in part on the current network configurations and the operation, updated network configurations for the first network domain;
• receiving, at the API server, a second API request;
• determining, at the API server, that the second API request includes a request for network performance data associated with at least the first network domain;
• receiving, at the API server and from at least the first router, the network performance data;
• and
• storing the network performance data in the datastore, the network performance data including at least an indication of network performance associated with the updated network configurations for the first network domain.

A method comprising:

• receiving a first application programming interface (API) request associated with an API server of a first network domain of a multi-domain network;
• determining that the API request corresponds to performance of an operation associated with the first network domain;
• determining, based at least in part on current network configurations and the operation, updated network configurations for the first network domain;
• receiving a second API request associated with the API server of the first network domain;
• determining that the second API request includes a request for network performance data associated with at least the first network domain;
• receiving from at least a first router associated with the first network domain, the network performance data;
• and
• storing, in a datastore associated with the first network domain, the network performance data, wherein the network performance data indicates network performance associated with the updated network configurations for the first network domain.
