Using An E-Model Implementation to Evaluate Speech Quality in Voice over 802.11b Networks with VPN/IPSec

摘要：

In this paper we present the results of an experimental analysis of voice traffic over 802.11b networks when protected by IPSecurity mechanisms. The main concern is the objective measurement of the impact due these mechanisms by means of our corrected ITU-T E-Model implementation, showing more precisely how the associated security overhead decreases speech quality and channel capacity.
