Internet traffic has been growing at a pretty fast rate, an increasing volume of which is video-driven. Telcos now have no option but to use transparent content caching in developing and managing their content delivery networks to improve delivery of both static and streamed data.
However, how transparent caching differs from traditional caching and its role in performing appropriate content filtering in CDNs is what most people do not seem to comprehend.
The following will help shine some light on this subject.
The Basics: Then and Now
Content caching is not a new term. Service providers have been using this technology for quite a long time to optimise their networks. The only difference with this age’s content caching is that there has risen numerous (and more advanced) approaches to efficient caching.
Traditional caching methods aimed at improving webpage, web object and HTML file response time by moving them closer to users. The problem is that bandwidth capacity grew speedily that this traditional caching became less and less relevant.
So, to match up to the growing internet traffic, modern caching techniques are now providing application-specific acceleration besides appropriate scaling for CDNs.
The Subject of Transparent Caching
As media streaming and downloading keep flooding your operator networks, it is imperative that you evaluate and deploy transparent caching to your network system to address more and varying internet content.
The significance of this move is to reduce network bandwidth and infrastructure costs while differentiating end-user broadband service to deliver better performance.
Traditional-form content caching sits only in peering locations, data centres and collocation spaces, and requires another entity other than the respective network operators to manage it.
Thanks to transparent caching, your CDN can intelligently decide which content to cache locally to deliver only the most relevant content close to consumers. This content filtering technology has further helped optimise networks as CDNs cache less popular content further down the network system.
