QUALITY OF SERVICE IN NETWORK

There are four major factors that decide the quality of network.They are

• RELIABILITY
• DELAY
• BANDWIDTH
• JITTER FOR PACKETS

On moving with reliability it is the characteristic which denotes the performance between transmission and the reception.Delay corresponds to the delay time. Then Jitter, it also deals with the variation in packets(informations).Bandwidth should be quite good in the tolerating level.
For example if we transfer a file or e-mail or accessing a web the reliability is HIGH (fast).In conferencing DELAY is HIGH.JITTER is HIGH in audio and video accession.BANDWIDTH is HIGH only with video.
