With the continuous development of cross-border e-commerce, international games, and overseas business, more and more enterprises, webmasters, and developers have begun to pay attention to the quality of server networks, especially the stability and speed of cross-border access. Among many network solutions, "9929 VPS" has gradually been promoted as a selling point by some service providers, but many users have a vague understanding of it, often confuse it with "CN2 VPS", or do not know the difference between the two.
1. What is 9929 VPS?
9929 is not a specific VPS product, but refers to a VPS that uses China Unicom's international export 9929 line as the main backhaul or export link. In other words, 9929 VPS refers to a VPS product whose network link is mainly based on China Unicom's AS9929 backbone network.
AS9929 is an international optimized export network provided by China Unicom for high-end government enterprises, cross-border finance, foreign trade enterprises, etc., and its positioning is similar to China Telecom's CN2 GIA. Compared with Unicom's traditional AS4837 (163 network), it has a shorter routing path, less congestion, lower packet loss rate and more stable cross-border links. 9929 lines mainly cover the dedicated network from core cities in mainland China to major international nodes such as Hong Kong, Japan, and the United States.
Therefore, 9929 VPS is a VPS deployed in a data center that supports China Unicom's 9929 network export and uses the 9929 dedicated line as the main backhaul route. This VPS has lower latency and less packet loss when accessed by domestic Unicom users.
II. What is CN2 VPS?
CN2 VPS refers to a VPS product whose export bandwidth is based on China Telecom's next-generation backbone network (CN2 GT/CN2 GIA). CN2 is a backbone network built by China Telecom for high-quality international access, with extremely low packet loss, high-quality bandwidth, optimized routing and high stability.
CN2 GT: Telecom Global Transmission Ordinary International Export Network.
CN2 GIA: Telecom's high-end dedicated line network, serving government, financial, and high-end commercial customers.
CN2 VPS is optimized for domestic telecom users first, with low telecom network latency and low packet loss. It is widely used in high-concurrency business, foreign trade, finance and other fields.
3. Comparison between 9929 VPS and CN2 VPS
After understanding the definition, we will compare the two in detail from the following dimensions.
1. Different network optimization objects
9929 VPS: Mainly optimizes the international access experience of China Unicom users. Unicom users have low latency, short routes and less packet loss through 9929 links. For access by telecom and mobile users, the performance improvement is limited.
CN2 VPS: Mainly optimizes the international access experience of China Telecom users. Telecom users have lower latency and less packet loss when accessing CN2 VPS. The effect on Unicom and Mobile users depends on the interconnection quality of the operator.
If your customer group or main visitors are mainly Unicom users, 9929 VPS is more suitable; if they are mainly Telecom users, CN2 VPS is more effective.
2. Routing quality and stability
9929 VPS: Unicom users have excellent cross-border access performance, but some cross-operator access during peak hours may have unstable backhaul problems.
CN2 VPS: CN2 GIA has higher stability during peak hours, extremely low packet loss rate, and small network fluctuations. In particular, CN2 GIA directly connects to nodes in Hong Kong, Japan, and the western United States, and has better routing performance.
In terms of overall stability, CN2 GIA VPS is better than 9929 VPS.
3. Bandwidth resources and configuration
9929 VPS: Most service providers provide medium bandwidth solutions (10M, 20M, 50M and other exclusive bandwidths), and there are many traffic package billing modes.
CN2 VPS: High-end CN2 VPS supports high-bandwidth solutions such as 100M, 1G, and 10G, and most of them support on-demand expansion and elastic bandwidth, which is suitable for high-traffic services.
CN2 VPS is more suitable for high-bandwidth and high-traffic services.
4. Price and cost-effectiveness
9929 VPS: Due to its positioning as a high-end dedicated line, the price is higher than that of traditional Unicom 4837 VPS, but usually lower than CN2 GIA VPS.
CN2 VPS: CN2 GT is reasonably priced, but CN2 GIA VPS is generally more expensive, especially for high-bandwidth and high-defense solutions.
If the budget is limited and the service is mainly for China Unicom users, 9929 VPS is more cost-effective; if the business has extremely high requirements for stability and access quality, CN2 GIA VPS is more worthy of investment.
Fourth, clarification of common misunderstandings of users
Misunderstanding 1: 9929 VPS and CN2 VPS are the same type of network?
9929 and CN2 are the international high-end export backbone networks of China Unicom and China Telecom respectively, and the two have different service objects and routing systems.
Misunderstanding 2: 9929 VPS is suitable for access by all operators?
9929 VPS mainly optimizes China Unicom's cross-border access, and has limited improvement for China Telecom and China Mobile users.
Misunderstanding 3: 9929 VPS must be much cheaper?
In high-bandwidth and high-defense solutions, the price of 9929 VPS is also not low, especially in core computer rooms such as Hong Kong and Japan.
If your business is mainly aimed at China Unicom users or your budget is limited, you can give priority to 9929 VPS; if your business is aimed at users across the country or requires extremely high stability, low latency, and strong bandwidth support, CN2 VPS (especially the CN2 GIA plan) is more suitable.
