A Technical Analysis Of A Distributed Disaggregated Chassis Architecture For Cable Aggregation Networks



Cable operators face many challenges to support the traffic growth originating from their commercial success. Network scale, resource efficiency, network availability, quality of service (QoS) and operational efficiency are key elements, especially at the IP aggregation layer.


Current IP aggregation architectures are built on monolithic chassis solutions, where configurations match specific requirements for each geographical site: three-to five-year growth forecasts, power limitations, space, and more.


This paper discusses the DDC architecture, how it compares to a spine-leaf architecture, and the benefits cable operators can expect from it at the aggregation layer.
