Overview of Distributed Content Delivery Network
Distributed Content Delivery Network is also called Content Delivery Network. Content delivery network is a group of this modern era which is geographically distributed and interconnected servers with different web connections. These content delivery networks work by caching the content of the Internet from the network location closest to the person to speed up its delivery. Most important motive of this network is to improve the performance of the web in this modern time and with today’s rich media to the users.
The Distributed Content Delivery Network is also designed to decrease the network problem due to long distances and also pulling server traffic over multiple networks. Reducing latency is very complex as more dynamic content, video and software as a service are delivered to an increasing number of phone devices.
Providers of DCDN keep content cached in their own network points of presence (POPs) or in third-party data servers. At the time a person’s requests content from a website, if the content is cached on a DCDN, its request will redirect to the server network closest to the user and send the cached content from its location at the network edge and this process is invisible to the user.
Wanna know how CDN works? Have a look
Distributed Content Delivery Network is the process of accessing cached content at the network edge of CDN is almost always transparent to you. The management of CDN software dynamically calculates which server is located very closely to you and delivers content based on those calculations. Edge Server of CDN communicates with the origin servers of the delivery of content cached content and new content that has not been cached to you.
These DCDN Edge servers decrease the distance that travel content and the number of hops made by the data server. The outcome is less packet loss, optimized bandwidth and provides you better performance. This will decrease timeouts, latency and jitter and improve your experience. In the event of an Internet attack or outage, content hosted on CDN servers remains available to some users only.
Organizations purchase services from CDN providers to deliver their content to users from the closest geographic location. CDN providers either host the content themselves or pay network operators and Internet service providers to host CDN servers.
