Content based byte-range caching using a dynamically adjusted chunk size

A method for a network node configured to adjust chunk size, the method comprising:

• determining at least one measured performance characteristic associated with the network;
• dynamically adjusting a chunk size for caching each of a plurality of segments of at least a portion of content, the dynamic adjustment of the chunk size being based on the at least one measured performance characteristic associated with the network;
• and
• causing transmission of a content request, according to the dynamic adjustment of the chunk size, for at least one segment of the plurality of segments of at least the portion of the content.

A network node configured to adjust chunk size, the network node comprising:

• chunk adjustment module configured to:
• determine at least one measured performance characteristic associated with the network;
• dynamically adjust a chunk size for caching each of a plurality of segments of at least a portion of content, the dynamic adjustment of the chunk size being based on the at least one measured performance characteristic associated with the network;
• and
• cause transmission of a content request, according to the dynamic adjustment of the chunk size, for at least one segment of the plurality of segments of at least the portion of the content.
