OTT traffic places huge demands on the backbone network. Three major trends are contributing to this: 1. Content moving towards 4K media streaming and requiring seven-times the bandwidth for each individual stream; 2. Increase in subscriber scale with the explosion of connected devices; 3. End users’ expectation of 24x7 connectivity with a high quality of experience to all of their favorite content from any location or device.
To address these trends, service providers must be able to satisfy consumers’ expectations and offer personalized services in a dynamic manner. To prepare the network to handle the relentless growth, service providers are reassessing their network and system architectures and building their content distribution networks based on a distributed network deployment model and disaggregated system architecture.
This paper will primarily focus on the shift in service providers’ requirements for the subscriber management function. It also discusses the disaggregation of functions in relation to subscriber management and distributed cloud-based networking.
Robert Haim of ACG Research conducted an analysis of Router 8801 deployment in a distributed subscriber management network architecture. The scenario compares Router 8801 to a leading second best alternative offering. The study found Router 8801 return on investment (ROI) levels of 299% for a single stack (IPv4 or IPv6 addresses) and 335% in a dual-stack (IPv4 and IPv6 addressing) mode over seven years. Total cost of ownership savings levels of 65% (single stack) and 66% (dual stack) were found during the same period.
