摘要： A method for reducing content redundancy in CCN includes distributing named media content or another type of content from sources to consumers through host devices and intermediate devices via a communication network using object messages that carry fingerprint names and data chunks. The named content is divisible into data chunks represented by fingerprint names such that a content fingerprint list for content identifies data chunks for the content using fingerprint names. The fingerprint names are based on content data in the data chunk such that data chunks with the same content data for the named content and for other content are represented by the same fingerprint name and data chunks with different content data are represented by different fingerprint names. A subsystem associated with the method includes consumer and source communication modules; a local storage device; message routing, fingerprint list processing, and object caching modules; and a message processing controller.

摘要： A capability is provided for reducing the costs of data transfers for networks using pricing heterogeneity. For data to be transferred between an application of a first network and a user device, the data may be transferred directly without using a second network or indirectly using a second network including a transfer of the data between the first network and the second network. In a network-based file system, a first network is primarily used for write requests and a second network is primarily used for read requests, and a data block is transferred from the first network to the second network based on a determination that a threshold number of read requests for the data block have been received. The determination as to when to transfer data between networks may be determined based on various costs associated with the networks.

摘要： A method for increasing localization of P2P traffic for content distribution includes distributing named content from hosting peers to requesting peers in conjunction with tracking nodes using fingerprint chunk messages that carry fingerprint names and data chunks. The named content is divisible into data chunks identified by fingerprint names such that a content fingerprint list for named content identifies the fingerprint name for each data chunk. Fingerprint names are based on content data in the data chunk such that data chunks with the same content data are represented by the same fingerprint name and data chunks with different content data are represented by different fingerprint names. When a data chunk is available from multiple hosting peers, selection of a hosting peer is based on comparing localization characteristics for the requesting peer to localization characteristics for the multiple hosting peers with preference to the hosting peer that localizes P2P traffic.
摘要翻译：用于增加用于内容分发的P2P流量的本地化的方法包括使用携带指纹名称和数据块的指纹块消息将命名内容从主机对等体分发到请求对等体与跟踪节点。命名内容可以分为指纹名称识别的数据块，使得命名内容的内容指纹列表标识每个数据块的指纹名称。指纹名称基于数据块中的内容数据，使得具有相同内容数据的数据块由相同的指纹名称表示，并且具有不同内容数据的数据块由不同的指纹名称表示。当来自多个主机对等体的数据块可用时，主机对等体的选择是基于将请求对等体的本地化特征与多个主机对等体的本地化特征进行比较，优先于本地化P2P流量的主机对等体。

摘要： Methods and apparatus are provided for identifying participants in a peer-to-peer network, such as an Ares P2P network. Peers are identified by sending a bootstrap request message to at least one peer; receiving a response from the at least one peer to the bootstrap request, wherein the response identifies one or more additional peers; and repeating the sending and receiving steps for the one or more additional peers until the bootstrap response satisfies one or more predefined criteria. The predefined criteria can be that the bootstrap response does not identify at least one new peer within a predefined period of time, or that the bootstrap response does not identify at least one new peer at all. The bootstrap requests are generally sent only to peers that have not been previously contacted. The bootstrap request message may comprise, for example, only one packet and requests that the recipient identify a predefined number of random peers. A list of identified peers can be presented to a user, for example, based on one or more demographic criteria.
