OFFLINE DOWNLOADER

摘要

In a method and system for facilitating peer-to-peer networking, a download set identifying content being downloaded by a client program is transmitted to a network device. The download set includes a reverse bit field containing elements that map to pieces of the content being downloaded. Each element of the reverse bit field has either a first value based on a corresponding piece of the content having been downloaded or a second value based on the corresponding piece of the content not having been downloaded. In response to an offline event indicating that the client program is no longer downloading the content over a network, an online event indicating the client program is resuming the downloading of the content is transmitted to the network device. Downloading of the content identified by the download set is completed by synchronizing the client program with the network device.
