Nope, AFAIK gzip header is also supported :)
is there any particular method to save all these bytes in buffers till i got complete data so i can start decompressor.
Reassembly api (fragment_add, fragment_add_seq) or composite tvb use with conversations or if your protocol is running atop TCP you can use DESEGMENT_ONE_MORE_SEGMENT :) just a keywords, but hope that helps.
