목차는 다음과 같습니다. What are the issues ? • Today, it is quite difficult to identify where the traffic comes from and goes to, even on our networks • Especially, so called "Hyper Giants" like Akamai, Google and more, are now changing the model of the Internet and traffic patterns • Also, legal framework for the piracy has been changed so that how traffic changed ? • Transparent Cache Technologies are emerging. So…

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.
CDN에 적용되는 가장 일반적 기술은 정적 콘텐츠를 캐시하여 서비스하는 Caching이다. CDN 사업자라면 기본으로 제공하는 Caching 외에 동적 콘텐츠를 가속하는 Dynamic Content Acceleration이야 말로 인터넷 상에서 콘텐츠를 가속하는 핵심 CDN 서비스이다. Dynamic Content Acceleration을 위한 Global Distributed DNS, Connection Pooling and HTTP Keep Alive, Dynamic Routing, TCP Optimization 등 다양한 기술들에 대해 알아본다.
