dc.description.abstract The rapid growth of the number of different telecom service users, the significant inventions of services, and web-based applications make the service providers expected to have a huge number of subscribers. People also show their interest to use the newly emerging services and applications since these services and applications are making life easier in day-to-day activities. Consequently, this makes the service providers have an enormous number of users. Even though it is good to increase the number of subscribers for the providers, the traffic that is forwarded from these subscribers to the provider’s network is also vast. As a result, this will make the service provider’s network become congested. Providers should have to consider their backbone network capacity while offering the different types of services. The increase in the number of customers without the timely deployment of the network expansion project will make the network to be exposed to congestion. Network expansion or deployment of new projects takes high cost as well as is time-consuming. But before the implementation of new projects, network bandwidth optimization should be implemented to use the available network resources effectively and efficiently. The motivation of this paper is to investigate and analyze the performance and link bandwidth utilization of the core network by implementing MPLS TE + QoS. The impact of QoS parameters is being analyzed by using two scenarios; MPLS LDP + BE and MPLS TE + QoS scenarios. Simulation tools such as GNS3, Ostinato, and PRTG are used to compare the performance of the two scenarios. The analysis result shows that in MPLS TE + QoS scenario packet loss is improved by 29%, throughput improved by 17.4%, and latency improved by 15.3%. From this result, it is highly recommended that service providers should have to deploy MPLS TE + QoS on their core (backbone) networks, which makes them more beneficiary. en_US
