摘要: According to one aspect, a method includes identifying a request for a piece of content, and obtaining a Moving Picture Expert Group (MPEG) Dynamic Adaptive Streaming over HTTP (DASH) manifest after identifying the request for the piece of content. The method also includes identifying at least one location at which the piece of content is located using the DASH manifest, wherein the at least one location at which the piece of content is located is a location from which the piece of content is arranged to be fetched.

摘要: According to one aspect, a method includes obtaining a packet at a network endpoint from a client via a first segment. The packet has a segment routing header that includes a list of addresses attached to a chunk entry, and is configured to identify at least a first chunk requested by the client. The method also includes identifying, at the network endpoint, the at least first chunk using the packet, and determining at the network endpoint if the network endpoint has the first chunk. If it is determined that the network endpoint has the first chunk, the first chunk is provided from the network endpoint to the client. Alternatively, if it is determined that the network endpoint does not have the first chunk, the packet is provided to a second segment.

摘要: According to one aspect, a method includes identifying at least a first chunk to be obtained, the at least first chunk including at least a first packet, and determining a deadline for the first chunk, the deadline being indicative of an amount of time before the first chunk is needed. The method also includes determining whether the deadline for the first chunk is relatively long, and de-prioritizing the first chunk with respect to obtaining the first chunk for queueing in a buffer when it is determined that the deadline for the first chunk is relatively long. Finally, the method includes obtaining the first chunk for queueing in the buffer, wherein obtaining the first chunk for queueing in the buffer includes obtaining the first chunk after obtaining a second chunk for queueing in the buffer, the second chunk having a shorter deadline than the deadline for the first chunk.

摘要: According to one aspect, a method includes obtaining a request for content through a physical network layer at a first node, the first node being one of a plurality of nodes in a content network layer, each node of the plurality of nodes including the content, wherein the request includes a first packet. The method also includes identifying a second node of the plurality of nodes from which to obtain the content, and inserting a segment routing (SR) list into the first packet, the SR list specifying an address of the second node as a next destination of the first packet. Finally, the method includes providing the packet including the SR list from the first node to the second node, wherein the second node is arranged to change the next destination of the packet to an address of the content included on the second node.
