Abstract: Systems and methods for compressing data in a network system communicated across a network are discussed. The network system may determine a data link characteristic for a data link between a source and a destination. A compression algorithm may be selected from among a plurality of compression algorithms based on the data link characteristic. A chunk of data may be compressed, using the selected compression algorithm, to be communicated over the data link. A compression ratio of the compressed chunk and the chunk uncompressed may be compared to a compression threshold. The compressed chunk may be provided, using the control circuitry, if the compression ratio is greater or equal to the compression threshold. The chunk uncompressed may be provided if the first compression ratio is less than to the first compression threshold.

Abstract translation: 讨论了通过网络传送的网络系统中压缩数据的系统和方法。 网络系统可以确定源和目的地之间的数据链路的数据链路特性。 可以基于数据链路特性从多个压缩算法中选择压缩算法。 可以使用所选择的压缩算法来压缩数据块，以通过数据链路传送。 可以将压缩块和未压缩的块的压缩比与压缩阈值进行比较。 如果压缩比大于或等于压缩阈值，则可以使用控制电路来提供压缩块。 如果第一压缩比小于第一压缩阈值，则可以提供未压缩的块。
