Comparative Analysis Amid National and International MPLS Local Loop Optimization and Commercial Impact

Wide Area Network (WAN) Capacity Planning faces frequent challenges to deploy cost–effective standard solution framework under IT Network budget cut situation, especially for Enterprise Organizations which operate across the globe. Since MPLS is well accepted WAN technology standard, until SD-WAN gets fully rolled out across the globe as standard cost–effective WAN platform, National and International MPLS would continue for years to come as foundation WAN connectivity options for the countries.In this study, comprehensive emphasis has been given for Local Loop technology enhancement (From Telco Based Leased Line to Ethernet/Fiber Optic Based Line) for WAN and associated cost impact which would enable IT decisions makers/Network Solution Architects to standardize country specific WAN solution via consciously selecting International MPLS or National MPLS with International MPLS touch point or combination of both as strategic direction to get both technology and cost being optimized making the country WAN infrastructure best fit for the purpose.The aim of the study is to track the progress of legacy TDM technology to Ethernet migration per country and overall cost benefit for both International and National MPLS WAN which would help define the roadmap for future bandwidth sizing and allocating country specific WAN budget, to meet the upcoming business requirement for existing size for WAN Bandwidth upgrade or new Site to live in the Global Wide Area Network.
