Abstract
A system and method for acquiring live content for a content delivery network (CDN). The method includes: intercepting a content manifest based on a content session initiated by a first user node and a broadcast server, where the content manifest includes at least one content identifier (ID) and its corresponding content chunk; fetching the content chunk to store in a memory of the CDN; receiving a request from a second user node for content of the content session; continuously determining a leader user node between at least the first user node and the second user node; and fetching at least a content chunk based on a content manifest of the leader user node.
