A Hybrid Packet-Circuit Network Needs Control SDN Enables The Solution

§  Hybrid Packet-Circuit Networks •  Packet-Circuit Convergence

in the Data Center Network

§  Enabled by SDN •  Optical and Packet devices

coexist in infrastructure layer

•  Unified control through Control and Application layers


§  Scheduled Events •  Virtual Machine migra1on (Server Virtualiza1on)

•  MapReduce / Hadoop

•  Storage applica1on reques1ng data migra1on (Network Storage)

§  Real Time Events

•  Network monitoring request for addi1onal bandwidth

― Based on Analy1cs (traffic threshold, packet conges1on, etc)

16

Example Use Cases


§  320 x 320 User Ports -‐ 640 Single Mode Fiber Termina)ons

§  Up to 100 Gbit/s per port and beyond (> 32 Tbit/s)

§  25ms setup )me, < 60ns latency

§  Ultra low power (45 WaKs) & small size (7 RU, 45 lb)

§  TL1, SNMP, OpenFlow APIs

The Next Generation S320 Photonic Switch

Optimized for Data Centers and Cloud Computing networks


§  The Plexxi CALIENT partnership is based on a specific implementa)on of the generic Hybrid DC concept.

•  Plexxi Control provides the SDN management and control plane func1ons

•  CALIENT’s S320 OCS provides high capacity op1cal “flyways” for funneling large traffic flows.
