Abstract:
1. A method of optimizing content delivery at a processing element in a content delivery architecture, comprising: determining whether a received message includes first metadata for content handling; if the message does not include the first metadata: retrieving second metadata stored at the processing element, the second metadata being applicable for handling a content; and using the second metadata to handle the content; otherwise, if there is second metadata stored at the processing element, the second metadata being applicable for handling of the content, applying the first metadata on the second metadata to establish third metadata; using one of the first metadata and the third metadata to handle the content; and storing the third metadata as the second metadata; wherein applying comprises modifying a subset of parameters in the second metadata based on corresponding subset of parameters in the first metadata; and wherein modifying comprises at least one of: removing a parameter in the second metadata if the corresponding parameter is absent in the first metadata; replacing the parameter in the second metadata if the corresponding parameter is present and non-empty in the first metadata; and preserving a parameter in the second metadata if the corresponding parameter is present and empty in the first metadata.
