Singapore Cn2 Direct Connection Comparison With Traditional Links Summary Of Test Results And Deployment Recommendations

This article focuses on the title of the evaluation, directly comparing the performance of Singapore cn2 direct connection and traditional link in the server deployment scenario. In short: If you are pursuing the "best" network experience (low latency, low packet loss, stable connectivity), give priority to CN2 direct connection; if you have a limited budget and tolerate higher delays, you can choose a lower-cost traditional link; if you are pursuing "cost-effectiveness", it is recommended to deploy a mixed deployment of active CN2 and backup traditional links.

Test the deployment of a Linux server in a Singapore computer room and use iperf3, mtr, ping and tcpdump for long-term comparison. The comparison is between the MPLS/BGP link via Singapore cn2 Direct and the legacy link of the regular Internet egress. The test period covers peak and non-peak periods, and measurement indicators include RTT, jitter, packet loss rate, throughput and routing stability.

Comprehensive results show that the average RTT through CN2 direct connection is about 30%~60% lower than traditional link (depending on the destination), and the jitter and packet loss rate are significantly lower; when bandwidth utilization is high, CN2 maintains a more stable throughput performance. For example: for short connection services for mainland China, CN2 RTT is often in the 40~70ms range, and traditional links often fluctuate from 80~150ms; packet loss CN2 is usually <0.1%, and traditional links can rise to 1% or higher at peak times.

Singapore cn2 direct connection usually uses the MPLS backbone with fewer hops and enjoys better peering and dedicated line guarantees, so it performs well when BGP convergence, traffic jitter, and packet loss bursts occur. On the contrary, traditional links rely on public network routing, and the path may jitter due to ISP intermediate forwarding and congestion points, especially on cross-border links and high load.

From a cost perspective, deploying CN2 direct connection is usually more expensive, including dedicated line or priority bandwidth fees, and higher monthly and relocation costs; traditional link is cheaper and has a low purchase threshold. It is recommended to purchase according to business priority: CN2 is preferred for delay-sensitive or high-frequency interactions (finance, games, VoIP); traditional links can be used for static web pages, backups, and low-frequency APIs.

For servers deployed in Singapore, recommended strategies: 1) Active and backup multi-line: active CN2 Direct connection, backup traditional link, realize traffic offloading through BGP policy or SD-WAN; 2) TCP parameter optimization: adjust congestion control, window and keepalive; 3) MTU and fragmentation optimization to reduce retransmissions; 4) Access CDN nearby and cache static content; 5) Deploy monitoring (ping, mtr, traffic and application layer probes) and automatic alarms; 6) Considering DDoS protection and cleaning services, CN2 can cooperate with operator cleaning solutions.

Summary: If you need the "best" experience and can afford the cost, choose Singapore CN2 direct connection for core business servers; if the budget is limited or the business is delay-tolerant, use traditional link; for most enterprises, the safest approach is a hybrid deployment, with CN2 direct connection as the main one to ensure performance, and the traditional link as a backup for cost savings and failover. Combining monitoring, BGP/SD-WAN policies and application layer optimization during deployment can maximize network investment return.
