White paper motivation I Emerging applications are entering the arena of Telco services with an unprecedented end-user acceptance. Video and Cloud Computing will be the drivers of the network evolution roadmap. As this trend becomes reality, traffic flows from Content Providers towards customers inject to the IP core Network an unprecedented amount of packets: – increase of the number and capacity of core routers directly materializing in both CAPEX and OPEX rises. Proclaims of the advantages of Virtualized resources over Physical ones are well known and can be found wherever in the Internet. The core network will adopt a key role in the Video and Cloud service provisioning as a whole since it may provide: – Connectivity capabilities for residential and business customers towards the datacenters and the external Internet – Highly reliable, low delay and high bandwidth demanding interconnections between the cloud/CDN datacenters themselves.

Current core and metro networks are not ready for these new traffic demands Core network may make up a bottleneck. Operation complexity of the current model. Core network operation and capacity should be adapted to new services demands Key transport technologies behind cloud ready networks Key requirements for a CDN/Cloud enabled network Core Architecture Connectivity Service Cost/bit Guaranteed Bandwidth Guaranteed QoS RangeFlexible BW Automated Operation Capacity beyond 10 Gbps Current Core Architecture (Annex) Internet (pure IP) LOWNO GlobalYES NO Static IP VPN HIGHYES GlobalNO Static L2 VPN MEDYES MANNO CDN/Cloud Enabled Network Flexible Connectivity Services LOWYES GlobalYES White paper motivation II
