An Advanced Distribution Layer Solution to Improve Bandwidth Utilization and Media Quality for Multi-Access Network Management in Wide Area Network

Due to ever growing data consumption for different Internet-based services, WAN (Wide Area Network) is becoming sophisticated day by day. Internet users are also expanding into new markets. So, business companies like ISP (Internet Service Provider) need to perform enhanced service providing tasks. MPLS (Multiprotocol Label Switching) is the technology to switch data between nodes of the topology only changing the label. The inherited nature of MPLS gives the scope to the service providers to maintain the complex networks more adeptly implementing traffic engineering and QoS (Quality of Service) in an extensive manner. In this research, a comprehensive analysis based on the real-world scenario has been made to utilize bandwidth, and improve media quality using MPLS technique over usual IP network (non-MPLS). The analysis is formed by specializing in the usually used QoS statistics: Bandwidth Utilization, Throughput, Packet Delay Variation, Packet End-to-End Delay, Traffic Sent and Received. The results clearly state that the MPLS based network provides highly efficient routes than non-MPLS Network. OPNET Modeler is the simulation software for this research to run the simulation scenarios, and the topology has designed according to the Cisco hierarchical model.
