Optimal format indication in distributed profiles ROHC compression
Mia Bakota, Julije Ožegović, Petar Bakota · 2007
Existing header compression systems, like ROHC, try to compress all headers in protocol stack together, using monolithic profiles. The distributed profiles concept is introduced recently, used to compress protocol headers individually. In this paper, the research for optimal format indication for distributed profiles is presented. After concluding that per protocol CRC and padding are obsolete, the compression efficiency is calculated for TCP, RTP and SCTP stacks, and further tested on real captured flows. The results obtained show, that distributed concept can be nearly as efficient as the monolithic one.
