Quality of Service Analysis of Traffic Engineering Implementation on VoIP Multi Protocol Label Switching (MPLS) Network
Abstract
The packet-switch data network in most cases does not guarantee the quality of service either partially or completely. Due to the challenges of traditional routers to provide this request, especially for voice and video, the Multi Protocol Label Switching (MPLS) method is used. MPLS is designed to add a set of rules to IP so that traffic can be classified, marked and applied to policies. Traditional IP routing is based on passing traffic to the destination as quickly as possible. As a result, the routing protocol looks for the shortest path to the destination based on the link cost (also called the metric) that the packet is forwarded to. Traditional IP routing does not take into account the bandwidth of available links. This can cause some links to be used too much compared to others. MPLS TE solves this problem. Source-based routing is applied to traffic from the headend router (MPLS TE tunnel source). Explicitly defined paths can be configured on the headend router where traffic for a particular LSP must follow. The performance is measured using parameters of throughput, delay, jitter and packet loss. The measurement results show a throughput value of 86 Kbps, delay 0.02 s, jitter 22.42 ms and packet loss 0%.References
