CDN is a network topology used to distribute content. Before we can fully understand it, we need to understand the other two terms. 1. Node Before users use a CDN network, CDN providers will deploy multiple nodes nationwide/globally. The nodes here can be considered as computer rooms or server clusters, and are professionally referred to as PoP (Point of Presence) or Origin Server. Each node is used to serve users around it, and because of its proximity, its response time is short. In addition, the node is a cluster composed of many servers, so it can withstand huge traffic. 2. Source Server The source server is the server where you deploy your website, which provides initial content for the entire CDN network. Without using CDN, every request from a user will reach your source server. The farther the distance between the user and the source server, the more packets are…

1、 Background Introduction （1） Characteristics of live streaming service Internet video live streaming is a form of news media that provides content that is produced and consumed from time to time. Over the years, it has developed into various business forms such as showbiz, games, e-commerce, and sports. The main characteristics are: real-time consumption of content generated in real time, with higher requirements for timeliness; Streaming media content consumes a large amount of bandwidth and requires more stringent network quality requirements; One person produces, multiple people consume, and the bandwidth scale is large. Live streaming CDN is currently the most effective technical approach to address this large-scale distribution scenario. Its main characteristics are to access nearby to provide a good access network environment, and multi-layer aggregation to reduce the distribution pressure on central resources, so as to meet the requirements of large-scale and timeliness of live streaming services. （2） Difficulties…

When traditional Internet operations and maintenance are faced with a surge in business volume, they often use the method of adding new servers and bandwidth to simply and roughly solve the problem, but the cost and response speed of this expansion are not ideal. Using CDN (Content Delivery Network) can easily, efficiently, and quickly solve many problems brought about by the rapid development of enterprises in the Internet. The following are six scenarios where CDN acceleration is more needed: APP acceleration Almost all industries and categories can be displayed on APP, and all conceivable ideas such as e-commerce, games, corporate office, takeaway, and so on are reflected on mobile devices. The performance of mobile applications directly affects the revenue of enterprises. A good mobile application experience will bring better user satisfaction to enterprises. For enterprises in rapid development, users will spread word of mouth due to the excellent quality of…

A content delivery network (CDN) is a group of servers strategically located in a geographical area for delivering digital media to end users, also known as a “content distribution network.”. CDNs can be used to deliver real-time streams and other types of digital media, and are typically built from collections of data centers distributed around the world. Each server is carefully arranged so that signal transmission can be quickly and easily transmitted from one site to the next, with the lowest possible delay to reach viewers. The location of the server is called a node, or PoP. Although traditional CDNs use physical servers, some CDN providers use a fully digitized approach and instead use computer networks. These are called edge servers. The purpose of real-time streaming CDN is to shorten the length of video that must be transmitted to maintain quality and reduce buffering. For example, streaming video from Beijing…

How much impact will a single outage of a large internet enterprise have? A foreign netizen replied, “I thought the end of the world was coming!” This is the roast of some netizens after the massive downtime of servers on Facebook, Instagram and other platforms on April 15, 2019, which shows the importance of stable network services. How to effectively ensure the service quality and user experience of their own websites and APPs has become a priority issue that every enterprise must consider. How cautious are these companies? This can be seen from the practice of Internet companies purchasing CDN (content distribution network) services. Especially for video platforms such as live streaming and on-demand, even under the pressure of burning money, they are willing to sacrifice costs and expend energy to purchase multiple CDN services at one time, spreading risks and praying for peace. It is against this background that…

Recently, many people have asked how to speed up foreign websites? What if the website doesn’t open every time, or the image/video buffer is particularly slow? In response to the above issues, there are many reasons why the website cannot be opened or the image buffer is particularly slow. This may be due to slow access by users in a specific region alone, or it may be due to the network problems of the visitors themselves. Websites such as these are located abroad, with a non domestic audience and a relatively small scale. Basically, there is no CDN acceleration, which can lead to slower speeds. What is a CDN? The full name of CDN is Content Delivery Network, or Content Delivery Network. Utilize CDN technology to publish website content to the edge of the network closest to customers by adding a new layer of network architecture to the existing Internet….

In the era of nationwide network business, integrating CDN becomes the first choice for live streaming enterprises With the rise of 4K video and intelligent terminals, IPTV video, OTT video, mobile applications, and cloud computing have brought enormous pressure to enterprise networks. The key challenges come from the core network, and are still growing rapidly. Therefore, there is an urgent need to introduce CDN content distribution networks. In addition, users’ pursuit of video experience is also a major challenge. How to shorten the response time of key experience indicators and reduce the traffic load on the backbone network is an important topic for enterprises, especially in the era of 4K ultra high definition and multi screen interaction. For enterprises, the deployment of a large number of new routers does not solve the problem well, as network traffic is growing faster than device bandwidth, forcing them to rethink how they can…

The vision of the Internet from the day it was born is to make the world no longer subject to geographical restrictions, which has also led to cross-border business becoming increasingly prosperous. Currently, cross-border e-commerce has become an important component of China’s overall trade, with B2B accounting for more than 70%. “Cross border means serving a large number of overseas users. We know that China’s network is quite complex, and networks outside China are even more exaggerated.”. Therefore, customer experience has also become the primary issue of cross-border B2B e-commerce, and the integration of Fireumbrella Cloud CDN not only accelerates the network and improves user experience, but also provides certain network security protection for e-commerce enterprises. According to relevant data, as of June 2022, the number of Internet users in China reached 1.051 billion, with a total of 19.19 million new users added in the half year. The Internet penetration…

CDNs are a critical part of any streaming media service infrastructure, storing content on servers around the world and providing it to users in near real-time. However, as the load and complexity of delivering video increases, more and more streaming media providers are turning to integrating CDN architectures. In a converged CDN architecture, you can simultaneously use multiple different CDN vendors to cache your video clips, and provide greater redundancy and performance advantages by leveraging the advantages of different providers and minimizing their weaknesses through intelligent load balancing algorithms. This article will explore the working principles of a converged CDN architecture and the benefits of converged CDN. 1、 What is a CDN or content delivery network? CDN (Content Delivery Network) uses servers worldwide to cache/store files such as images, videos, code libraries, and so on. When a user requests a media object from your website/service, the request is first forwarded…

From the perspective of websites and applications, faster page load times mean that your users will have a better user experience, resulting in longer stay times and more access.
