How Content Delivery Network Works

The CDN is a caching system that directs your customers to the nearest caching server (or node). As the customer accesses your website, they retrieve content from the node instead of the origin server, reducing the load on that server and allowing for much faster delivery of the content. With On-demand Propagation, content from your origin site is instantly pushed out to each caching server only when it is being requested from a specific geographic location. This results in increased performance and cost savings. Our online CDN Control Panel provides you with real-time information and easy-to-use tools for monitoring, distributing, and managing your content. Launch Tutorial

Content Delivery Network Definition

There is more than one content delivery network definition on the web. Content delivery network, aka content distribution network (CDN), is a way to deliver content more efficiently by placing copies of data on many servers and responding to requests from the server nearest the user. Wikipedia's content delivery network definition focuses on CDN's goal of maximizing bandwidth, by having clients access data copied near them, instead of the origin (central) server. By delivering content from the Internet's edge, CDN's speed content delivery, circumvent bottlenecks and provide protection from traffic spikes that can bring down servers, and render web sites unreachable.

Others define CDN as a service which includes making geographically disperse data copies, and then dynamically and intelligently determining where to serve from, based on expected latency, which depends on geographical proximity, server load, network topography and network conditions at the time. Content types include web objects,media files, software, documents, applications, and real time media streams. A different content delivery network definition applies to specific high-traffic events such as live Web broadcasts. In this case, the CDN works by continually mirroring content from an origin server to other servers, known as edge servers. Viewers are served by their local servers.

The PEER1 CDN uses GLOBAL load balancing and caching servers across 17 international data centers, for fast, smooth delivery, from any data center, without any site modification. It improves response time and user experience, enhancing web servers' quality, reliability, and scalability.

More Information About Content Delivery Network (CDN)

A content delivery network improves response time and user experience, enhancing web servers' quality, reliability, and scalability. A content delivery network (CDN) is an assemblage of servers, geographically dispersed across many locations, containing copies of data in order to deliver content more quickly and efficiently and maximize access to the data. Downloading web pages' static content (images, stylesheets, scripts, Flash) is 80-90% of the users' response time. Delivering media files, software, documents, applications, and real time video/audio streams strain the server and network, and is affected by the user's proximity to the web server, due to latency and packet loss.

CDNs optimize delivery and increase throughput and availability by delivering data to users from nearby servers, instead of the central server. This reduces the load on the central server, avoids bottlenecks, and multiplies the network speed. For example, Yahoo! discovered that properties which moved static content off their application web servers to a CDN improved end-user response times by 20% or more. Content delivery network nodes are close to the edge network where users are, employ multiple backbones, and cooperate by caching and interchanging content and using global load balancing. Switching to a CDN is a relatively easy code change with zero capital cost.

PEER 1's CDN works in any data center worldwide, without any server or site modification. PEER1 caching servers store content in its FastFiber Network of 17 North American and European data centers, and use GLOBAL load balancing technology for the fastest, smoothest delivery.
