摘要
A cache handoff method and system (10) for managing cacheable streaming content requested by a mobile node within a network architecture (12) is disclosed. The network architecture includes a first subnet (14) and a second subnet (16). The cache handoff system includes a first caching proxy (20) in the first subnet to supply a content stream in response to a request of the mobile node (18) e.g., a mobile IP node in the first subnet. In addition, the cache handoff system includes a second caching proxy (22) in the second subnet. The first caching proxy (20) may initiate a cache handoff of the request to the second caching proxy (22) when the mobile node relocates to the second subnet. The second caching proxy (22) may seamlessly continue to supply the requested content stream as a function of the cache handoff.
