Optical Interconnection of CDN Caches with Tb/s Sliceable Bandwidth-Variable Transceivers featuring Dynamic Restoration

A scalable cost-effective solution for high service availability featuring low latency is required for CDN caching. Recently, a field of study is that MAN data centers, within the latency budget, act as a backup for other local data centers of lesser reliability. Given the low latency target of caching, the optical layer is the preferred option to interconnect caches. However, carrying the backup traffic from one data center (DC) to another with...
