Central offices (COs) provide critical access/aggregation networking services (e.g. for cable, fiber, DSL, wireless customers) and there are more than 10,000 COs in the United States alone. Network services in a central office have traditionally been built using proprietary, complex and single-function boxes but that is changing with the advent of the virtual Central Office (VCO) that brings service agility, improved customer experience, and a significant reduction in costs. Using a OPNFV Enterprise VCO concept first demonstrated at the OPNFV Summit — and run through a TCO calculator from Intel — a new Solution Brief has been developed that shows how CSPs can deliver network services to their customers at up to 43% lower total cost of ownership (TCO).
