Abstract
There is provided methods and apparatuses for transferring photonic cells or frames between a photonic switch and an electronic switch enabling a scalable data center cloud system with photonic functions transparently embedded into an electronic chassis. In various embodiments, photonic interface functions may be transparently embedded into existing switch chips (or switch cards) without changes in the line cards. The embedded photonic interface functions may provide the switch cards with the ability to interface with both existing line cards and photonic switches. In order to embed photonic interface functions without changes on the existing line cards, embodiments use two-tier buffering with a pause signalling or pause messaging scheme for managing the two-tier buffer memories.
