1. A system, including:

  • one or more processors configured to;

    evaluate, at a distribution manager, a distribution topology;

    based at least in part on the evaluation of the distribution topology, determine a set of feasible source peers, wherein a feasible source peer is capable of serving at least a portion of content requested by a first destination peer;

    access a set of content delivery policies stored in a data store;

    determine, at least in part by evaluating the set of feasible source peers against the accessed set of content delivery policies, that designating a given source peer included in the set of feasible source peers to function as a content source for the first destination peer would violate at least one content delivery policy in the accessed set of content delivery policies, and in response, prune the given source peer from the feasible set of source peers, wherein evaluating the given source peer comprises applying content delivery policies in the set of content delivery policies in an order according to a ranking of the content delivery policies;

    designate, at the distribution manager, a first source peer in the pruned set of feasible source peers to function as a first content source for the first destination peer; and

    designate, at the distribution manager, a second source peer to function as a second content source for a second destination peer, wherein the second destination peer is configured to obtain, from the designated second source peer, at least a portion of content requested by the second destination peer; and

    a memory coupled to the one or more processors and configured to provide the one or more processors with instructions.
