CDN nodes are typically deployed in multiple locations, often via multiple backbone networks. The number of nodes and servers that make up a CDN varies by architecture, with some reaching thousands of nodes, tens of thousands of servers on many remote points of presence (PoPs), and others building global networks with a handful of Geographical PoPs. A CDN is built on a network of interconnected servers that are strategically placed together to minimize the distance between the user and the nearest server. These servers cache copies of web content. When a user requests a web page, dynamic request routing ensures it reaches the closest available CDN server. If the CDN server has an up-to-date copy of the requested content in its cache, it will respond to the request directly. If not, the CDN server will forward the request to the origin server, which will fill the request. CDN servers can…

A Content Delivery Network (CDN) is a globally distributed network of servers or Points of Presence (PoP) whose purpose is to provide faster content delivery, content is replicated and stored throughout the CDN so users can access storage geographically away from the user The nearest location data. This differs from the traditional approach of storing content on only one central server, where clients access a copy of the data near the client, rather than all clients accessing the same central server to avoid bottlenecks near that server. What is a Content Delivery Network? What is a Content Delivery Network used for? CDNs are designed to optimize the delivery of web content, and some of the key advantages they offer companies and their users include: Faster load times: Content cached by a CDN is geographically close to its users, reducing the travel distance required for requests and responses. As a result,…

1、 Content distribution challenges for large file downloads and video on demand For download type scenarios, common segmentation scenarios include: mobile app stores, game app stores, game updates, and mobile operating system updates. For video type application scenarios, the main segmentation scenarios include short videos, long videos, online education, OTT set-top boxes, radio and television media, and music websites. Why would you compare downloaded application scenarios with video on demand application scenarios? Because the application scenario of video on demand is actually a large file download scenario, the two application scenarios have high business similarities and many common issues. The difference between them is that video on demand has higher requirements for access performance. The challenges faced by the two scenarios in terms of content distribution mainly fall into three categories: The user experience problem is mainly reflected in the complex environment of domestic operators and poor access effects across…

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…

According to the acceleration range of the domain name, you can choose to purchase the corresponding regional acceleration package (the acceleration range is the designated region of the corresponding package) or the global unlimited regional resource package (except for Chinese Mainland). (1) Resource Package Type “CDN Downlink Universal Traffic” is applicable to static or dynamically accelerated downstream traffic of http and https. The http and https protocols are deducted by a coefficient of 1: 1.15, and the https protocol does not charge an additional fee for the number of static accelerated requests. How to understand coefficients? The actual https traffic used is 100GB, which is equivalent to 115GB of deducted resource packet traffic. The quota of a resource package can be understood as a concept such as “points”, where different products in the same unit require different points to be deducted. In what order are deductions made? When the resource…

Huosan Cloud’s pay-as-you-go resources adopt a monthly settlement mode. The system will charge based on the amount of usage used by the user around 8:00 every day, and update the real-time consumption details. That is, the real-time consumption details are estimated bills and balance pre deduction, and no actual deduction has been completed. Therefore, by default, the balance of the resource package needs to be updated every month after the monthly bill is issued, We can also pre estimate the usage of resource packages using the following method. (1) View resource package balance On the management console page, select Resource Package Management, filter the resource packages you want to view, and click Details. You can see the remaining available amount of the current resource package and the deduction status of the resource package after the historical monthly bill settlement. (2) View the withholding details of this month Note: The real-time…

Description of account arrears (1) Arrearage rules When you have not paid the bill generated by the CDN service or the account fee is less than 0, the service is in arrears. (2) Arrearage process ① Notice of arrears. On the day of arrears, Huosan Cloud will send you an email and SMS notification of arrears, and your system background login interface will send a pop-up reminder. ② Protection period for arrears. Immediately enter the protection period after arrears, and within the protection period, Huosan Cloud will push a reminder to you every day. Protection Period Duration: The protection period duration varies depending on your authentication status. The protection period for individual authenticated users is 3 days, and the protection period for enterprise authenticated users is 5 days. Restrictions during the protection period: During the protection period, the services/features you use will be subject to certain restrictions, including the inability…
