Abstract
A computerized method of delivering popular content of a service delivery apparatus (SDA) in an asymmetrical network topology. The method comprises receiving a first acquisition request for content from a user node (UN) over an upstream data link, the request comprising at least a content identification (CID). An instruction is sent to the UN to redirect content requests to the SDA. A second acquisition request is sent from the SDA to a content source (CS) for the content requested by the first acquisition request, upon determination that the downstream data link between the UN and the CS is inaccessible to the SDA, the request including at least the CID. The content is received by the SDA from the CS. The received content from the SDA is sent to the UN.
