throughput test results of huawei cloud singapore cn2 and other cloud vendors’ lines

introduction: this article focuses on the "throughput test results of huawei cloud singapore cn2 and other cloud vendors' lines", using controlled laboratory methods to compare and measure the throughput and stability of different cloud vendors' export lines at singapore nodes. the purpose of this article is to provide a reference for network architects and operation and maintenance personnel, explain the testing methods, key results and optimization suggestions, and make it clear that the results are greatly affected by time periods and paths.

this test aims to evaluate the throughput capability and stability of huawei cloud singapore cn2 lines and mainstream cloud vendor lines in multiple scenarios. the method includes tcp/udp concurrent flow testing based on iperf3, stress measurement of different number of concurrent connections and packet sizes, and continuous hour-level scenario recording of delay and packet loss. all tests were conducted under the same time period, similar instance specifications and egress bandwidth quotas to minimize variable interference.

the test environment selects a cloud host instance in the singapore region as the export end, and the destination end covers nodes in mainland china, southeast asia, europe and the united states to simulate common cross-border business. the comparison objects are the standard public network lines of several mainstream cloud service providers and the operator's interconnection lines. network monitoring simultaneously records rtt, packet loss rate, jitter and number of retransmissions to fully understand the sources of throughput fluctuations.

in the short-term concurrent flow test, huawei cloud singapore's cn2 line showed high peak throughput capabilities and the stability of quickly establishing connections. the overall trend is that in cross-border transmission, especially in the direction of mainland china, cn2 lines have long been the same as or better than ordinary public network lines of some manufacturers, showing more concentrated peaks and smaller fluctuations. however, the specific gap will be affected by the operator's strategy and time period in the target country.

tests for cross-continental transmission (such as singapore to europe and the united states) show that line selection has a more obvious impact on tcp throughput. cn2 optimized lines are relatively robust under cross-border backhaul, packet loss recovery and congestion control, and can maintain higher effective throughput in high packet loss scenarios. however, for short-term burst traffic or extremely high concurrency scenarios, the difference will be masked by congestion in the middle section of the end-to-end link.

increasing the number of concurrent streams often improves bandwidth utilization that is difficult to achieve with a single connection. the test found that when the packet loss rate is less than 1%, both the cn2 line and the opponent can fully utilize the bandwidth through multi-stream; but when packet loss or jitter increases, the cn2 line performs more stably in retransmission and congestion convergence, resulting in average throughput that is better than some ordinary public network lines under poor link conditions.

the difference in throughput may be due to factors such as backbone interconnection, operator bgp policy, egress link quality, and traffic engineering optimization. cn2 lines usually focus on optimal routing and backhaul optimization, which is helpful in reducing packet loss and jitter in cross-border scenarios, thereby improving the effective throughput of tcp. however, the internet ecosystem and partners of different cloud vendors will also lead to differences in specific performance.

summary: based on controlled testing, huawei cloud singapore's cn2 line performed well in a number of cross-border throughput and stability indicators, especially in high packet loss or backhaul-sensitive scenarios. however, the actual effect will fluctuate with time, destinations, and operator strategies. recommendation: conduct end-to-end testing of the target path before production deployment, combine multi-point monitoring and traffic control strategies, and use hybrid solutions such as dedicated lines or sd-wan when necessary to ensure stable throughput.
