Machine-to-Machine bandwidth consumptionEnterprise Data Center A Private, Public, and Provider Data Center C Hybrid CloudsEnterprise Data Center B Provider Data Center DBandwidth challenge coming from large, latency-sensitive virtualmachine migrations and database sync  a Packet Transport task.8 Terabyte-sized VM migrations © Ciena Confidential and Proprietary
  • 9. Key Take-Aways New usage patterns indicate connection-oriented behavior Majority of metro and core traffic is “transit traffic” General-purpose routers are too costly, power hungry For majority of traffic, need  Packet processing by a router less overhead per packet takes longer than frame forwarding by a Layer-2 switch. Work Done per  Use pre-determined path to Packet final destination to avoid hop-by-hop lookups. File size Packet handling bifurcating into two functions: 1. Specialized IP service processing (including routing) 2. Packet Transport (simple tandem switching)9 © Ciena Confidential and Proprietary
