  2. Introduction • A typical SIP message may range from a few hundred bytes up to two thousand bytes or more. • Use of SigComp (SIP signaling compression mechanism) and ROHC (Robust Header Compression mechanism) schemes reduces the signaling and the protocol header overhead, respectively.

  3. Overhead for different SIP packets

  4. SigComp and ROHC

  5. Compare different compression algorithms
