摘要： In a coding system, input data within a system is encoded. The input data might include sequences of symbols that repeat in the input data or occur in other input data encoded in the system. The encoding includes determining a target segment size, determining a window size, identifying a fingerprint within a window of symbols at an offset in the input data, determining whether the offset is to be designated as a cut point and segmenting the input data as indicated by the set of cut points. For each segment so identified, the encoder determines whether the segment is to be a referenced segment or an unreferenced segment, replacing the segment data of each referenced segment with a reference label and storing a reference binding in a persistent segment store for each referenced segment, if needed. Hierarchically, the process can be repeated by grouping references into groups, replacing the grouped references with a group label, storing a binding between the grouped references and group label, if one is not already present, and repeating the process. The number of levels of hierarchy can be fixed in advanced or it can be determined from the content encoded.
摘要翻译：在编码系统中，对系统内的输入数据进行编码。输入数据可能包括在输入数据中重复或发生在系统中编码的其他输入数据中的符号序列。编码包括确定目标段大小，确定窗口大小，识别在输入数据中的偏移处的符号窗口内的指纹，确定偏移是否被指定为切割点并分割输入数据，如一组切点。对于如此识别的每个段，编码器确定段是引用段还是未引用段，用参考标记替换每个引用段的段数据，并将引用绑定存储在每个引用段的持久段存储中，如果需要的话。分层次地，可以通过将引用分组为组来重复进程，用组标签替换分组的引用，存储分组的引用和组标签之间的绑定（如果尚未存在），并重复该过程。层次级别的数量可以固定为高级，也可以从编码的内容中确定。

摘要： In a network supporting transactions between clients and servers over a network path having operating characteristics to overcome, data is transported to overcome the operating characteristics using user affinities and dynamic user location information to selectively preload data, or representations, signatures, segments, etc. of data, in order to overcome the one or more operating characteristic. Examples of operating characteristics to overcome include bandwidth limitations, errors and latency. The dynamic location information can be stored in data structures accessible by agents of a data server and the data structures are populated based on user activities with respect to proxies associated with user locations, or the dynamic location information can be obtained implicitly as proxies maintain connections after termination by clients and the use of those maintained connections for preloading of data for the users associated with those clients. The data being preloaded can be protocol-specific data or protocol-independent data.
