As a short video service provider, whether it is for the Japanese local market or the entire Asian region, choosing the right server bandwidth is the key to ensuring a smooth user experience. Short video services are different from general websites or text information applications. They have the characteristics of high concurrent access, large traffic transmission, low latency requirements, and multi-terminal adaptation. Therefore, the bandwidth selection of short video servers must meet business requirements such as high concurrency, large traffic, and low latency.
When choosing short video server bandwidth in Japan, it is necessary to consider multiple factors:
1. User scale and daily activity level
Bandwidth requirements first depend on the number of users and daily activity level. Taking the Japanese market as an example, if the platform has less than 10,000 daily active users, generally 100M to 1G bandwidth can meet the initial demand. If the user scale reaches millions, multi-G or even higher bandwidth access needs to be considered.
2. Video resolution and bit rate
Different video clarity corresponds to different bit rates. The average bitrate of 480p resolution is 1-1.5 Mbps, the average bitrate of 720p resolution is 2-3 Mbps, the average bitrate of 1080p resolution is 4-6 Mbps, and the average bitrate of 2K and above resolution is 8 Mbps or above. Video platforms usually need to support multi-bitrate adaptation to adapt to different network environments. High-bitrate content transmission significantly increases bandwidth consumption.
3. Peak value of concurrent access
Short video business has obvious traffic peaks, such as at night, holidays, special events, etc. Bandwidth configuration should be based on peak concurrent access volume as a reference standard, rather than the average value.
4. Whether to use CDN or edge nodes
If CDN nodes are deployed locally in Japan or in Asia, the bandwidth pressure of the source server can be effectively shared. Therefore, the bandwidth demand of the source server can be appropriately reduced. However, if it is completely dependent on the source station to directly connect to users, the bandwidth demand needs to be increased accordingly.
5. Whether to support user uploads
If the platform supports users to upload short video content, the bandwidth demand of the server entrance and exit will increase at the same time. At this time, not only the downlink bandwidth is important, but the uplink bandwidth also needs to be fully guaranteed.
Bandwidth selection suggestions for short video servers in Japan:
Combined with the characteristics of Japan's network environment and the short video business model, the bandwidth selection can be referenced according to the following situations:
For start-up short video platforms with less than 10,000 daily active users (start-up stage), or applications in the testing and internal testing stages, the recommended bandwidth is 100M~500M exclusive bandwidth, which can be combined with the local CDN pilot in Japan to optimize the access experience
With 100,000 daily active users (growth stage), as the business develops and the user scale expands, the concurrency increases significantly. The recommended bandwidth is 1G~5G exclusive bandwidth. At this stage, it is recommended to deploy CDN simultaneously to reduce the pressure on the source station
With more than one million daily active users (mature platforms), for short video platforms that have been formed and have stable business, the user group is huge. The recommended bandwidth is 10G and above exclusive bandwidth. At this stage, the focus should be on building national/regional edge nodes, CDN clusters, and load balancing systems. The bandwidth of the source station only bears the necessary back-to-source traffic.
Common misunderstandings in bandwidth selection:
When deploying short video servers in Japan, some companies or developers are prone to the following misunderstandings in bandwidth selection:
1. Only look at the average traffic, not considering peak concurrency. In actual business, the peak bandwidth is much larger than the daily average. If the bandwidth configuration is based only on the average traffic, it will not be able to cope with peak access.
2. Ignore the symmetry of upstream and downstream bandwidths, especially for platforms that support user uploads, it is necessary to pay attention to whether the upstream and downstream bandwidths are symmetrical to avoid upload jams.
3. Confusion of bandwidth and network latency. Large bandwidth does not mean low latency. It is also necessary to pay attention to the line quality and routing optimization of the computer room.
4. Inadequate CDN construction and reliance on source stations to directly connect to end users will greatly increase bandwidth costs and reduce access experience.
When deploying short video servers in Japan, reasonable bandwidth selection is a key link to ensure smooth business operation and excellent user experience. Bandwidth selection should be scientifically calculated based on multiple dimensions such as business scale, user distribution, video bit rate, and concurrent peaks, and combined with technical means such as CDN and load balancing to jointly build an efficient and stable short video service platform.
