US CN2 servers refer to physical servers or VPS solutions located in US data centers (mainly in the western United States, such as Los Angeles, San Jose, and Seattle), and their return links use China Telecom's next-generation backbone network CN2. CN2 GT is China Telecom's global transit backbone network, which has better performance than the traditional 163 network. CN2 GIA is China Telecom's high-end dedicated international link, with exclusive bandwidth, priority routing, and the lowest latency. US CN2 servers are particularly suitable for cross-border services for Chinese mainland telecom users, and can provide lower latency and more stable cross-border access experience.

　　Requirements for servers for large-volume live broadcast services

　　Compared with ordinary websites and API interface services, large-volume live broadcast services have higher requirements for server infrastructure:

　　1. High-bandwidth support capabilities: Live video streams require stable and continuous high-bandwidth output, and 10M, 50M, 100M or even higher bandwidths are often standard.

　　2. Low latency and low jitter: Live broadcast services have high real-time requirements. The smaller the user-side latency, the better the experience.

　　3. High concurrent connection support: The live broadcast platform needs to support thousands, tens of thousands or even more users to access online at the same time.

　　4. High availability architecture: The live broadcast service needs to ensure 7×24 hours of uninterrupted operation, and the network and hardware must have high availability.

　　5. Global coverage and optimized return link: Cross-border live broadcast needs to take into account the access experience of overseas users and mainland Chinese audiences.

　　Is the US CN2 server suitable for high-traffic live broadcast services?

　　1. Bandwidth capacity

　　US CN2 servers are usually deployed in top data centers, supporting exclusive bandwidth ranging from 10M to 10Gbps, and the bandwidth limit can fully meet the needs of high-traffic live broadcasts. In particular, the CN2 GIA solution supports exclusive international exports and exclusive bandwidth resources to avoid congestion during peak hours.

　　2. Network quality and stability

　　The core advantage of the US CN2 server lies in network link optimization, especially for China Telecom users. The CN2 GIA line has a direct return link to China, with fewer hops, low packet loss rate and good stability. Test data shows that the delay from CN2 GIA in the West Coast of the United States to China Telecom users is 130~170ms; the packet loss rate is lower than 0.1% all year round; the peak performance is much better than the 163 ordinary line.

　　For live broadcasting business, this means more stable video streaming; smoother viewing and less lag on the audience side.

　　3. Support high concurrent connection capability

　　The US CN2 server uses enterprise-level hardware and supports configuration options such as large memory, large storage, and hardware firewall. Most service providers support Xeon Gold and EPYC high-core processors, 128GB, 256GB or more ECC memory; NVMe SSD high-speed storage array. Combining high-performance hardware with CN2 high-quality network, it can easily support tens of thousands of concurrent connections and live broadcast distribution nodes.

　　4. Comparison of return link performance

　　Unlike ordinary US West Coast servers that use Line 163 and Unicom 4837, CN2 US servers have significant advantages in the return link. If the live broadcast audience is mainly composed of Chinese mainland telecom users, CN2 GIA is the best choice for the return link.

　　5. Cross-platform compatibility and networking flexibility

　　The US CN2 server supports flexible deployment: it can be used as the main live source server to distribute streams to CDN or edge nodes. It can be integrated with the public cloud to build a hybrid cloud live broadcast architecture. Supports defense enhancement solutions (high-defense IP, hardware firewall) to ensure business security.

　　Limitations and precautions of US CN2 servers

　　Although US CN2 servers have obvious advantages in live broadcasting, there are also areas that need attention:

　　1. The price is relatively high. The CN2 GIA solution is more expensive than ordinary US West servers due to its exclusive links and high-quality bandwidth, especially the large bandwidth package.

　　2. Limited optimization for non-telecom users. CN2 mainly optimizes the links of telecom users, and the improvement for China Unicom and China Mobile users is limited. If the audience group operator composition is more diverse, it is necessary to match multi-line optimization or BGP solutions.

　　3. High-bandwidth solutions need to be planned in advance. Some data centers have limited large bandwidth resources, and the feasibility of bandwidth solutions should be confirmed in advance to avoid restrictions on business launch.

　　In a comprehensive comparison, US CN2 servers can well support the deployment needs of large-traffic live broadcast services in terms of bandwidth capacity, link stability, hardware performance, and scalability. Especially for cross-border live broadcast projects for Chinese mainland telecom users, CN2 GIA servers are an ideal choice.
