Unifying Control and Management of Disaggregated Networks with Pluggable Transponders - Who Controls

Moscone Center

 

Unlike the performance-oriented transponders, pluggables trade-off performance for cost, size and energy with fast adoption of 400ZR/400ZR+, ongoing standardization for 800ZR/ZR+ and 1600ZR/ZR+ in sight. A pluggable from a vendor may be hosted in the shelf (an optical ROADM or an IP router) from another vendor. Current IP and optical transport networks, or even optical networks from different vendors, are managed separately. The inclusion of a pluggable from vendor on equipment from another vendor blurs control and management boundaries and raise many issues.

In this workshop, the following open challenges will be addressed:

  • Which alternatives are valid for hierarchical SDN control of disaggregated networks?
  • What are the current limitations of the recently proposed standards?
  • Who owns the responsibility for malfunction of each component?
  • Overall, who will be responsible for the pluggable – the layer/operational unit in charge of the pluggable, or of the system (ROADM or IP router) that hosts the pluggable?
