1. A method for managing the streaming of digital video content to multiple clients, the method comprising:

  • identifying an attribute of a content element that is streamed to a client from a stream server; and

    selecting a protection mechanism for the content element as a function of the attribute, wherein the protection mechanism enables streaming of the content element to the client from another stream server in the event of a resource failure;

    wherein selecting a protection mechanism for the content element comprises;

    mapping attributes of content elements to a set to categories such that an attribute falls within a category of the set of categories; and

    mapping each category of the set of categories to a protection mechanism;

    wherein the combination of the two mappings creates an indirect mapping between attributes of content elements and the protection mechanisms.
