Omni-Directional & Colourless<br />
Optimized ROADM Network architecture<br />
Significant g Benefits:<br />
No Manual intervention<br />
required to support multiple<br />
source-destination paths<br />
Improved Planning; it can<br />
be done without human<br />
intervention<br />
Allow “as as needed” needed<br />

Video, mobility & SP Infra Trends<br />
Where is traffic growth coming from going forward?<br />
The Cisco Visual Network Index (VNI) is the company's<br />
ongoing effort to forecast the growth and use of <strong>IP</strong><br />
networking worldwide<br />
Global <strong>IP</strong> traffic will increase by a factor of six from<br />
2007 to 2012, reaching 44 exabytes per month in<br />
2012, compared to fewer than 7 exabytes per month in<br />
2007 2007.<br />
Video on demand (VoD), <strong>IP</strong> television (<strong>IP</strong>TV), and<br />
Internet TV will account for nearly 90 percent of all<br />
consumer <strong>IP</strong> traffic in 2012<br />

• Converged Network, interchange of Transport and <strong>IP</strong> Roles<br />
• Eliminate OEO reduces NE’s (aka CAPEX) and Opex<br />
• Interoperability and standardization of Open Transport Layer<br />
