CSDN Newsletter Recently, there is news that the vast number of Tsinghua teachers and students to provide scientific support of Tsinghua University open source Mirror mirrors.tuna.tsinghua.edu.cn is about to be closed by Tsinghua University Network Center. The webmaster has issued an open letter to the outside world.

The following is the contents of the open letter:

The Open-source Mirror has provided great support for scientific research, and foreign excellent software projects have mostly been released in the form of open source (Open-source open). The use of Open-source software, on the one hand, does not require any fees, on the other hand, there is no use of pirated commercial software ethical and legal issues.

and the open source mirror station is the world's outstanding open source projects gathered together to facilitate the students and teachers to install, update, use at high speed. And many foreign excellent science and technology institutions have set up the tradition of open source mirror station. From Tsinghua University open source mirror installation of open source software, download rate of 10mb/s level, and from the Open source project official website Download, the rate is about 50KB-500KB/S, not waste network traffic and increase the burden of campus network export. According to the statistical data, the average monthly savings of the school flow of about 5000GB. In short, open source mirror station is the "software housekeeper" of scientific research worker, having a open source mirror station inside the campus is able to make use of computer to complete scientific research work even more.

Tsinghua University Open Source Mirror was founded in 2011, in a short span of a few years quickly gathered a group of enthusiastic and technical skills of students to maintain, has been in the international and domestic has a wide range of impact, many times by the IT Industry news website reported. At present, there are 44 kinds of open source project mirrors total about 5000GB, of which 12 kinds of open source project mirrors have been officially approved, the official server will be from China or even Asia directly directed to Tsinghua University, the use of the official sub domain name directly to Tsinghua University, or on the official website to specify address and school , which is a great honor and affirmation for the open source mirror station and Tsinghua University.

Because it has been unable to obtain formal support for the Network Center, the open source image station can only be "cosmopolitan", often disconnected, power off, and down. Each relocation will cause the service to be unavailable for a long time, and will often receive inquiries from domestic users as well as from foreign open source organizations.

Not long ago, we received a final notice that Tsinghua University open source mirror station will be off the deadline and moved out of the campus network room, then, the use of open source software students and teachers will have to use other siblings to provide the mirror station or directly from the software project official website to download, update, Not only inefficient but also increase the burden of campus network export. We do not want this to happen, and we expect to be helped to make this decision changed.

Open Source software mirroring

Many successful open source software use flexible "package" management mechanism, the software is divided into a number of independent functional modules, packaged on the server to facilitate users to download and use. For example, in many Linux distributions, most applications are published as "packages", and users can directly connect to servers that provide "packages" to get software and updates.

Because of the high volume of packages, only a handful of official servers are completely unable to meet the needs of Open-source software users around the world. Moreover, these servers are often located abroad, Tsinghua teachers and students if want to visit, will be in the campus network export and international exports to generate a lot of traffic, not only slow, but also crowding out a limited network resources.

  The effective way to solve this problem is to set up some servers closer to the user and provide a "package" that is consistent with the official server at all times. These servers are the foundation of an open source mirroring station. With the "relay" role of the open source mirroring station, users can get the "package" resources needed for research and development more quickly and easily.
