摘要: Methods and systems for prioritizing content are described. A request for a first content object is received at a caching proxy. A search of an access log of the proxy cache for a portion of the first content object is then performed. The size of the portion of the first content object on the proxy cache is calculated and the normally utilized size of the segment of the first content object is derived. A comparison is then made between the size of the portion of the first content object on the proxy cache and the normally utilized size of the first content object requested.

摘要: Methods and systems for supplying media over communication networks are described. In one embodiment, a media supplier determines whether a media object hosted on a web server will be supplied to a client by streaming or not by streaming. Preferably, if the determination is to stream, the media supplier streams the media object to the client. Otherwise, the media supplier preferably allows the host web server to supply the media object to the client. In some cases, the same media supplier may be capable of supplying clients with media objects hosted on any of at least two web servers.

摘要: A method and system for streaming media objects. A streaming system includes a group of end nodes and at least one core node connected via an overlay network. The end nodes cache segments of media objects and stream the media objects to a client segment by segment. Each end node stores segment indices for locating segments cached on end nodes or a core node in the system. The core node is a dedicated proxy which fetches media objects from a remote media server and streams the media objects to a client when the media objects are unavailable from the end nodes.
摘要翻译: 一种用于流媒体对象的方法和系统。 流系统包括一组终端节点和经由覆盖网络连接的至少一个核心节点。 终端节点缓存媒体对象的分段,并将媒体对象逐段流式传输到客户端。 每个终端节点存储用于定位缓存在终端节点上的段或系统中的核心节点的段索引。 核心节点是从远程媒体服务器获取媒体对象的专用代理,并且当媒体对象从终端节点不可用时,将媒体对象传送到客户端。

摘要: A peer-to-peer communication system in which a peer communicating with a tracker node on a local torrent can locate and download files that are not currently available from other peers communicating on the local torrent. To enable this, the tracker node maintains collaboration information for a list of files. The collaboration information includes, for each file, a list of locations at which a full copy of the file may be located. The list of locations may include active peers, dormant peers and remote tracker nodes. The collaboration information may be obtained from each peer when it joins a local torrent. Upon joining the torrent, the peer may provide the local tracker node with a list of files that it is willing to serve.
