Performance Evaluation of Internet Telephony Systems Through Quantitative Assessment
Schubert Shou-Boon Foo, Hui Sun · 1997
An Internet telephony system functions like a conventional telephone to support real-time voice communication over the Internet. The performance of such a system depends upon a number of factors which include network performance, computing resource, voice processor, signal acquisition, output transducer, and method used to establish a connection between users. A performance evaluation using quantitative assessment techniques have been conducted for four Internet telephony systems, namely, CoolTalk, Net Meeting, Internet Phone, and Speak Freely. These were used to assess the factors of network performance, voice processor and connection method.
