Data Center Network Trends

Flat Topologies No Oversubscription Large machine-machine data

flows 75% of Traffic is East-West Low latency required Scale to 100G & beyond

75 % Traffic

Data Center Aggregation

Places huge demand on Cluster Aggregation layer • Doesn’t scale well• Expensive in $, power,

space, & adds latency• Replace or Upgrade

Application: Hybrid Datacenter NetworksThe New Hybrid Data Center Solution

Packet Network handles short bursty flows

OCS Trunk network switches in on demand to support large persistent flows.

• Massive Bandwidth• Ultra Low latency

SDN Management & Control Plane manages flows between fabrics

OCS network expands to support 100G and beyond without upgrade

Scalable, High-Capacity, Low-Latency, Future-Proof

A Hybrid Packet-Circuit Network Needs ControlSDN 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

12 © 1999-2013 CALIENT Technologies – All Rights Reserved

Scheduled Events• Virtual Machine migration (Server Virtualization)

• Storage application requesting data migration (Network Storage)

Real Time Events• Network monitoring request for additional bandwidth

―Based on Analytics (traffic threshold, packet congestion, etc)

1. Traffic within the datacenter has escalated dramatically leading to a network scalability problem that needs a solution!

2. Photonic switching technology has become small, ultra low in power consumption, and cost-effective

3. Recent trends towards software defined networking have opened the way for control of hybrid packet-circuit network architectures
