A Testing Packet Delay Variation and Packet Loss Problem on Local Area Network Based on ITU-T Standard

Abstract

A good computer network will always be the mainstay of its users. All traffic are aiming to come in/out to device with shortest delay. However, there will be times where our router, switch or access point (AP) start dropping packets because the traffic coming to fast in/out that device can process. The Quality of Service (QoS) computer network traffic is an effort to maintain or manage propagation traffic from source to destination. There are several telecommunication organizations such ETSI and ITU. They have been released recommendation standards. According to TIA/EIA-568-A, the maximum allowed length Cat 5e, Cat 6 cable is 100 m solid horizontal cable between the patch panel and wall jack. However, our research showed the length Cat5e above 130m for connecting router gateway to bridge free from Packet Delay Variation (PDV) and PL problem. The shortest length below 100m does not guarantee will free from PDV and PL problem.
