Computation of caching policy based on content and network constraints

摘要

An apparatus comprising a first content oriented network architecture (CONA) node configured to couple to at least one second CONA nodes and implement collaborative caching in accordance with criteria comprising at least one content caching objective and at least one network operational objective, wherein the content caching objectives are in accordance with the network operational objectives. Also disclosed is a network component comprising a caching policy engine configured to receive network policy information and compute a caching policy in accordance with the network policy information, an inter-cache data transfer component coupled to the caching policy engine and configured to fetch a plurality of content object portions in accordance with the caching policy, a storage engine coupled to the inter-cache data transfer component and configured to cache the content object portions, and an eviction algorithm component coupled to the storage engine and configured to determine which, if any, of the cached content object portions are to be evicted.

1. A network component comprising:
a caching policy engine configured to receive network policy information associated with content object portions to be transferred between a source node and a destination node and compute a caching policy based on the network policy information, wherein the caching policy engine comprises a global caching policy component configured to:
communicate with a remote global caching policy component in a remote network component to receive partial content caching information comprising constraints describing the content object portions to be transferred between the source node and the destination node and describing a probability that the content object portions to be transferred can be received by the destination node, wherein the network component is not the destination node; andcompute the caching policy based on the network policy information and the partial content caching information; an inter-cache data transfer component coupled to the caching policy engine and configured to fetch at least one of the content object portions in accordance with the caching policy; a storage engine coupled to the inter-cache data transfer component and configured to cache at least one of the content object portions; and an eviction algorithm component coupled to the storage engine and configured to select cached content object portions for eviction from the storage engine.
