A new report from US firm Infonetics Research has found that over 50% of service providers around the world are planning to deploy transparent caching or Content Delivery Networks (CDNs) by 2014, as they race to keep up with rocketing network loads.
“The 3-headed monster of video, mobility, and the cloud is putting enormous pressure on operator networks, and throwing more routers at the problem isn’t the answer because traffic is rising much faster than equipment prices are falling,” notes Michael Howard, Infonetics Research’s co-founder and principal analyst for carrier networks.
“This is driving a fundamental shift in how IP edge networks are being architected, with carriers combining their fixed and mobile networks for operational efficiencies and using caching and content delivery networks (CDNs) to move frequently used content closer to the consumer, speeding up response times and greatly reducing the amount of traffic crossing the network.
The study identifies three top drivers for deploying CDNs: a better quality of experience for customers, network optimisation, and reducing the cost and traffic load associated with delivering over-the-top (OTT) video content.”
The survey, conducted with incumbent, independent wireless, competitive, and cable operators from around the world, found that they rate Cisco, Alcatel-Lucent, and Juniper as the top service provider edge router and/or CES vendors; Cisco and Juniper also top the list of core router manufacturers.
