One-way delay measurement of a corporate TCP/IP network spanning two distant sites reveals that the mean one way delay is 500 ms. Which of the following applications can run satisfactorily over this network?
(a) Voice-over IP
(b) File Transfer
(c) Web Browsing
(d) E-mail
(e) Video on demand
Answer:
Following applications can sun satisfactorily over given network: (a) File Transfer (b) Web Browsing (c) e-mail.
The reason VOIP and VOD may not run satisfactorily is that the tolerable delay of these applications are several milliseconds only. e.g. <= 400 ms for VOIP.
