What is a CDN and How Does it Work? (Bunny.net)

A content delivery network (CDN) like Bunny.net is a system that distributes the Internet’s content to remote locations via the delivery of packets of data over the network. In other words, it is the Internet’s equivalent of an information superhighway, allowing users in a given area to each have access to content created by other users in that area. A CDN enables content to be obtained at the point of usage, reducing the need for large infrastructure and transmission costs. The Internet’s leading providers provide CDN services to customers through the Internet backbone carriers (IBTS). All my websites use Bunny.net CDN, it is the best, affordable and easy to configure.

CDN technology enables content delivery with improved quality of service (QoS) and increased capacity. It also provides customers with improved control and flexibility over their networks. With the advent of new Internet application technologies such as video streaming, voice broadcasting, and real-time web logs, customers can now enjoy a more comprehensive network experience. CDN technology makes distribution of content on the Internet more efficient by improving the quality of service and reducing the potential for overloads. The advantages of a content delivery network are:

Convenience for end-users. Providers of CDN technology to enable customers to receive and deliver dynamic, interactive web content without the overhead of additional server processes. Customers can thus take advantage of advanced features not available otherwise, such as software-based routing, application queues, load balancing, and content delivery optimization (CRO). These benefits eliminate the need for expensive servers and customer IT costs.

Improving page load times. The introduction of cdn technology reduces the delays experienced during the start of website pages and during page downloads. The improved page load times lead to higher conversions and more sales. In addition, these delays are averted by improving the performance of servers used by ISP providers.

Decreased cost of maintaining networks. A CDN improves the efficiency of content distribution across multiple networks. In CDN system, data is distributed across load balancing servers through a differentiated Internet connection (DAS). This connection has a lower latency compared to other common connections, which enables data to be accessed quickly.

Better performance for end users. A CDN works well for competitive online content delivery such as streaming video or audio. Using a cdn works well for high-bandwidth online content delivery. For example, live streaming videos and games experience an unprecedented level of streaming speed with CDN, which can take up to 5 seconds in some cases for a single frame of video being presented.

Robustness of servers used by ISP providers. As all computers on a public CDN are linked together, the performance of individual computers can affect the entire CDN. For this reason, large ISPs like Verizon use their own colocation facility to host streaming servers rather than having their customers use their own internal servers. This provides ISPs with better capability to deliver streaming content as well as reducing operational expenses.

Edge network benefits. An edge network is simply a part of a CDN that is geographically close to the user’s location. This ensures that streaming content can be delivered at very fast speed since there are no delays that could occur in the main network. In addition to speeding up delivery, an edge server also reduces operational overhead and capital expenses.

More efficient revenue sharing between end users and service providers. In most cases, end users pay subscription fees to ISP providers to access CDN resources while they are online. The cost of these transactions (such as for bandwidth and processing) is passed on to the end users through higher CDN administrative fees. By using a CDN, service providers can share these transaction costs with end users and improve their bottom line.

No need for equipment or software upgrade. Upgrading equipment or software is a common practice among ISP providers when they want to improve their business offerings. But most importantly, such upgrade activities consume massive amounts of time, money, and resources. With a telco cdn system, all updates and modifications can be done remotely from any PC that is connected to Internet through a data network. Thus, an ISP does not need to maintain any additional hardware or software for such activities.

Faster CDN performance. Most broadband connections today are already very fast. Even broadband connections without advanced features such as cache are already fast enough for basic web applications. But CDN technology makes it even faster by adding additional layers of caching and other bandwidth-efficient mechanisms. This means that the typical CDN system will have to deal with a much heavier load than its conventional peer-to-peer network counterparts.
