Win10 online push Win7/Win8.1: The global network burden is huge

Microsoft this time in order to allow the majority of Win7/Win8.1 users to easily upgrade to Win10, the online push installation package. However, because the Win10 system installation program itself is relatively large, the pressure on the network is obvious. It is reported that in order to enable this push to proceed smoothly, Microsoft has reserved bandwidth of up to 40 Tbps, and currently uses more than 10 Tbps, which is still growing.

But it’s good that Microsoft’s push is based on the user’s local time, which can avoid the huge CDN pressure caused by the simultaneous opening of the world. The so-called CDN is a content distribution network built on the network. It relies on the edge servers deployed in various places, through the load balancing, content distribution, scheduling and other functional modules of the central platform, so that users can obtain the required content nearby, reduce network congestion and improve User access response speed and hit rate. The key technologies of the CDN are mainly content storage and distribution technologies.

The basic principle of CDN is to widely use various cache servers to distribute these cache servers to areas or networks where users are relatively concentrated. When users visit websites, they use global load technology to point users' accesses to distances. The most recent work on the normal cache server, the cache server directly responds to user requests.

The foreign media also compares with Apple's release system downloads and other events, saying that the bandwidth occupied by such events is about 8 Tbps. From the data point of view, Microsoft's Win10 push bandwidth is about five times the size of Apple.

This Win10 large-scale push is still in progress, and the process of completing this process quickly and steadily is the wish of every relevant user. After the push is completed, how to make the user install smoothly and solve various problems encountered during the installation process may be the first problem that Microsoft needs to solve next.
