1. A method comprising:

  • aggregating, by an application-layer traffic optimization (ALTO) server that stores network topology information for a network of a plurality of endpoints that provides a service, the plurality of endpoints into a plurality of PIDs, wherein each PID of the plurality of PIDs includes one or more endpoints of the plurality of endpoints;

    generating, by the ALTO server, an ALTO map for the service that includes representations of each of the PIDs and outputting the ALTO map to a client of the ALTO server;

    receiving, by the ALTO server, a status update for an endpoint of the plurality of endpoints that comprises information indicating a condition of the endpoint that affects a performance of the endpoint with respect to the service;

    generating, by the ALTO server and based on the status update for the endpoint, an updated ALTO map and an incremental map revision that enables the client of the ALTO server to conform the ALTO map to the updated ALTO map to account for the received information for the endpoint; and

    sending, by the ALTO server to the client, the incremental map revision.
