Quality of Service Enhancement of a Carrier Supporting Carrier Network using MQC QOS

Abstract

Quality of Service (QOS) is the major key element in research nowadays. The rapid development with internet and its associated technologies led the users to easily access the internet. Due to that, demand for network access has increased tremendously. On contrast, this development has increased the demands on ISP’s. In order to meet the increasing demands, ISP’s employ many technologies based on Service Level Agreements (SLA). Carrier Supporting Carrier (CSC) network based on MPLS VPN is one of the methods used to meet the ISP’s requirements. MPLS backbone network will lend its bandwidth to send the customer ISP’s traffic to its customers. This in turn increases the traffic load on MPLS networks. This work proposes a QOS enhancement of CSC network using Modular Quality of service Command Line Interface (MQC QOS). Traffic classes are defined and policy maps are employed to apply QOS policies to prioritize the traffic respectively. TELNET and ICMP protocols are considered to analyze the QOS policies and prioritization schemes. Bandwidth sharing will take place according to the priority value assigned to each traffic classes. In this work, highest priority of 30% is given to class (PING) whereas lowest of 10% priority is assigned to traffic class TELNET. According to that, traffic gets prioritized when both traffics are given.
