Mobile-broadband users are demanding spontaneous access to video content, a higher-quality experience and more convergent mobile services than ever before. During the London 2012 Olympic and Paralympic Games, around 50 percent of search requests in the UK were from mobile devices. The US broadcaster NBC (National Broadcasting Company) also reported that more than 45 percent of online video streaming of the games was delivered to mobile devices (Figure 1) [1]. Subscribers like to be able to consume content anytime, anywhere. As a result, new business models are emerging in which the line between fixed and mobile is becoming indistinct. Service providers – especially over-the-top (OTT) players and content aggregators like App stores, Netflix, Amazon and so on – are making premium content available anytime, anywhere on a variety of devices. Mobile network operators (MNOs) are being challenged by the need to give consumers what they want, while preserving the economics of their networks and creating new opportunities for revenue growth.

ADVA had a nifty new trick for their mobile backhaul switches to learn, video caching. At MWC they were showing off their new Cachejack and told SemiAccurate a bit about how it all works. It is an easy enough concept to grasp, take a carrier Ethernet switch and slap storage on it so you don’t have to send the same bits over the long haul wires again and again. This saves precious bandwidth to and from the remote sites, a scarce commodity in most places. The devil however is in the details, and that is what ADVA’s Cachejack is said to have worked out.

Alcatel의 통신사업자 CDN과 Transparent Caching의 통합 솔루션에 대한 Whitepaper입니다. 통신사업자 CDN 솔루션 제조사와 Transparent Caching 솔루션 제조사는 나누어져 있었는데 최근에는 단일 벤더가 CDN과 Transparent Caching을 통합하여 제공하는 방향으로 진화하고 있습니다. 역시 트렌드는 통합, 단일화, 단순화이네요.
