Network Cloud Disaggregating the Traditional Routing Model
The wide adoption of cloud services changed the architecture of large data centers, driven by new virtualization technologies, low cost white-boxes and the development of automated operations. In contrast, service providers’ network architecture has remained almost the same for the last 30 years, with expensive propriety hardware, multi-layer architecture and dedicated systems per network service. While NFV attempted to bring some of the data center virtualization efficiencies to networking, it has been limited to just a few services and low-throughput access solutions.
The emergence of networking merchant silicon technologies opened the door for service providers to embrace web-scale networking by adopting the architectural concepts of large clouds. CSPs can now build high-scale converged infrastructures that support any service on any port, with cloud native software and microservices. Such a disaggregated approach can scale higher than any traditional approach, at a much lower TCO.
