Systems, methods, and devices for delivering content (e.g., multimedia streams, video files, documents, images, text, operating system updates, app store downloads, etc.) from a content source to one or more receiver devices over an internet protocol (IP) network. Network devices may be configured to bypass a content delivery network (CDN) to deliver a bulk of the content via IP multicast, and to utilize the CDN and multipath connectivity between the content source and the receiver devices to deliver the remaining portions of the content via unicast.
