摘要： A method for selecting a preferred cache (312a) for the substantially simultaneous download of digital data from a plurality of caches (312; 312a-312d) is disclosed. The plurality of caches (312; 312a- 312d) hold substantially identical copies of the digital data. The method comprises the steps of requesting an address of the preferred cache (312a) and selecting the preferred cache (312a) from the plurality of caches (312a). The selection of the preferred cache (312a) is derived from a location identifier of a client (102) requesting the download of the digital data.
摘要翻译：公开了一种用于选择用于从多个高速缓存（312; 312a-312d）基本上同时下载数字数据的优选高速缓存（312a）的方法。多个高速缓存（312; 312a-312d）保持基本相同的数字数据副本。该方法包括以下步骤：请求优选高速缓存（312a）的地址并从多个高速缓存（312a）中选择优选高速缓存（312a）。从请求下载数字数据的客户机（102）的位置标识符导出优选高速缓存（312a）的选择。

摘要： The invention relates to a content distribution network for the distribution of a digital object in a peer-to-peer network with a plurality of peers having a peer location identifier and a download client (103a) for downloading the digital object. A plurality of distributed caches (312a, 312b) is present in the peer-to-peer network. At least some of the plurality of peers (102a, 102b, 102c) are connected to at least some of the plurality of distributed caches (312). A publisher's computer network (403) is connected to at least one of the plurality of distributed caches (312) for distributing the digital object to at least one of the plurality of distributed caches (312). A private tracker for managing the distribution of the digital object among the plurality of distributed caches (312a, 312b) and a public tracker for managing the distribution of the digital object between the plurality of peers (102a, 102b, 102c) are present. The invention also includes a method for the distribution of a digital object over a peer-to- peer network to at least one of a plurality of peers (102). The method comprises a first step of placing at least a first piece of the digital object on a content supplier (402,- 312), a second step of transferring at least the first piece of the digital object to a least one of a plurality of distributed caches (312), a third. step of announcing the availability of the digital object to at least one of the plurality of peers (102) and a fourth step of downloading at least the first piece of the digital object to the at least one of the plurality of peers (102).

摘要： A network (10), such as a computer network, is disclosed. The network (10) has a plurality of nodes (20; 120) and includes a first node (30, 130) for storing pieces of a digital object and having a storage (40, 50; 140, 150). A plurality of connections are present between the first node (30, 130) and the plurality of nodes (20; 120). The first node (30, 130) has a requester for requesting one or more pieces of the digital object, a transmitter for transferring one or more pieces of the digital object to at least one further node among the plurality of nodes (20; 120), a receiver for receiving content availability messages from at least some of the plurality of nodes, and a sender for sending a limited content availability message to at least one further node (20; 120) among the plurality of nodes (20, 120). The limited content availability message indicates a subset but not all of the pieces of the digital object available through the first node (30; 130). A method of providing pieces of digital object from a first node (30, 130) to a plurality of nodes (20, 120) in a network (10) is also disclosed which includes a first step of sending to at least one further node (20b, 120b) among the plurality of nodes the limited content availability message. In the second step a request for pieces of the digital object is received from at least one of the plurality of nodes (20, 120) and finally in the third step one or more pieces of the digital object are transferred to the at least one of the plurality of nodes (20,120).

摘要： A method for the distribution of digital objects (370) in a peer-to-peer network is disclosed. The digital objects (370) are distributed in a plurality of pieces (371-373). At least some of a plurality of peers (40a-d) are connected to other ones of the plurality of peers (40a-d) and at least one of the peers (40a-d) is connected to at least one cache (30). The method comprise: - a first step of receiving a message relating to the digital object (370) from a first one of the plurality of peers (40a-d) at the at least one cache (30) - a second step of checking whether meta-information relating to the digital object (370) is available in the at least one cache (30); - a third step of requesting the meta-information from a meta-information source in the event that the meta-information is unavailable in the at least one cache (30); - a fourth step of receiving the meta-information at the at least one cache (30); and -a fifth step of storage of the plurality of pieces (371-373) in the at least one cache (30) based on the meta-information.
