SYSTEM FOR DISTRIBUTING NAMELESS OBJECTS USING SELF-CERTIFYING NAMES

摘要

A content replication system can cache nameless Content Object across multiple replica servers in a Content Centric Network (CCN). During operation, a CCN client can obtain a nameless Content Object from one or more content-hosting services by disseminating an Interest for a data collection, and receives a Content Object that includes a manifest for the data collection. The manifest can include Content Object hash (COH) values for a set of other Content Objects of the data collection. The client then determines a name prefix for a content-hosting service that hosts the data collection, and generates another Interest for a Content Object of the data collection. This Interest's name includes the name prefix for the content-hosting service, and also includes a COH value for the respective Content Object. The client disseminates the new Interest over CCN to obtain the respective Content Object of the data collection.

1. A computer-implemented method, comprising:
disseminating an Interest for a data collection; receiving a Content Object that includes a manifest for the data collection, wherein the manifest includes Content Object hash (COH) values for a set of other Content Objects of the data collection; determining a name prefix for a content-hosting service that hosts at least a portion of the data collection; generating a second Interest for a respective Content Object of the data collection, wherein the second Interest's name includes the name prefix for the content-hosting service, and also includes a COH value for the respective Content Object; and disseminating the second Interest to obtain the respective Content Object of the data collection.
