Content sizes in bytes after encoding the object using the message formatwithout compressionA fair amount of this is likely to be due to redundant information, especially ofstring values, which Jadex Binary can exploit (though Jadex XML uses a similarmechanism). In addition, text-based formats like FIPA SL and Jadex XML usea large amount of redundant strings to represent their formatting, such as tagsin the case of XML.In order to test this assumption, another set of tests was performed, whichwere identical to the previous tests but added an additional compression pass,converting it to the gzip-format, which uses the DEFLATE algorithm[11] toreduce data redundancy.Content Size (Compressed)7000600056356119Size in Bytes50004000300020004542424110000Jade FIPA SL Jadex XML Java Serialization Jadex BinaryFig. 11. Content sizes in bytes after encoding the object and further compressing theformat with gzipThe results shown in Figure 11 substantiate the assumption. The DEFLATEalgorithm drastically reduced the redundancies in both FIPA SL and Jadex XMLwith FIPA SL now even coming out ahead of Jadex XML. Nevertheless, both113
