UPC parameter estimation using virtual buffer measurement with application to AAL2 traffic
D.W. Petr, Gopi K. Vaddi, Yong-Qing Lu · 2003
This paper describes an efficient, measurement-based technique for estimating all minimal sets of usage parameter control (UPC) parameters for variable bit rate (VBR) ATM traffic streams. This virtual buffer measurement technique is applicable to simulation or live traffic measurement environments and is considerably more efficient than direct evaluation using the generic cell rate algorithm (GCRA). We derive analytically the relationships between virtual buffer measurements and minimal sets of UPC parameters as determined by GCRA, then illustrate the technique by estimating and verifying minimal UPC parameters for ATM Adaptation Layer, Type 2 (AAL2) traffic streams representing voice traffic.
