METHOD AND SYSTEM FOR OPTIMIZING METADATA PASSING IN A PUSH CONTENT PROCESSING PROTOCOL

摘要

A method and a system for optimizing metadata passing in a push content processing protocol are provided to supply a general dynamic content delivery architecture where a provider of an application or a content can be added without changing architecture. A content delivery optimizing method comprises the following steps of: receiving a content and metadata envelope at a processing element; checking the content and metadata envelope in order to determine whether the content and metadata envelope includes metadata for the processing element; if so, extracting and caching the metadata; if not so, retrieving metadata for a content provider associated with the content from a cache on the processing element; and applying the extracted or retrieved metadata to the content and metadata envelope.
