1. Telecommunications Congress – Andicom 2009 Building a Resilience Infrastructure For Content Distribution Presented by: Dallas Maham Sr. Product Manager Tellabs Optical Networking Group October 29, 2009

2. The problem with the OLD Model Most Social Networks can be Affected by single individuals Viral Distribution Network Congestion Poor Service Experience Revenue Contraction Traffic Storm Fixed Hierarchy Congestion Traffic Users

3. Why a Resilient Infrastructure is a good approach … Most Social Networks can be Affected by single individuals Viral Distribution Extra capacity via stacking Local BW control Traffic Storm Dynamic Hierarchy Modify Network Coverage  1  1 Congestion Traffic Users

17. Example: Existing IP Router Based Network: Pt to Pt DWDM Fully redundant architecture, but underutilized pipes result in extra network costs Network Distribution Layer Aggregation Network Locations One for One 10G connections to Core Routers (6 each in this example) 13 wavelengths to support this mesh Actual average throughput is about 5% of capacity 2G total bandwidth per site required in this example network Network Core Layer To Access Layer and End User Buildings
