Evaluate The Connectivity Delay And Bandwidth Stability Indicators Of Hong Kong Computer Room High-defense Server Rental

evaluate the connectivity delay and bandwidth stability indicators of hong kong computer room high-defense server rental

question 1: how to judge whether the basic connectivity of hong kong computer room is qualified?

three indicators should be used to judge basic connectivity: connectivity rate (ping success rate), round-trip delay (rtt), and packet loss rate . commonly used tools include ping, traceroute, and mtr, which use multi-point and multi-period tests to cover peak and valley periods. for hong kong computer rooms facing domestic users, the normal rtt should be in the 20-100ms range, and the packet loss rate must be less than 1% for a long time to be judged as "qualified".

testing recommendations

it is recommended to monitor at least once every 1 minute for 24 hours to obtain stable samples; for cross-border links, attention should also be paid to the fluctuations of submarine optical cables and operator transit nodes.

question 2: will the high-defense strategy significantly increase latency and jitter? how to evaluate?

high-defense servers may introduce additional hops and processing delays when cleaning traffic. when evaluating, compare the changes in rtt, jitter, and packet loss before and after protection is turned on. ideally, the average delay caused by protective equipment should not exceed 5–20ms, and the jitter increase should be acceptable. for high-defense based on cloud cleaning, pay attention to check whether there is a difference between full-traffic bypass or local cleaning.

measurement points

use icmp/tcp multi-protocol testing and real business stress testing (such as concurrent small and large packets) to evaluate the impact of cleaning paths on the business.

question 3: how to quantify bandwidth stability and available bandwidth?

bandwidth stability

monitoring indicators

focus on monitoring the changes in packet loss with bandwidth usage, the increase in tcp retransmission rate and rtt with bandwidth usage, which directly reflect the stability of the link under high load.

question 4: what impact do different operators and interconnection strategies have on latency and bandwidth stability?

operators' backbone, peering, and transit policies directly affect cross-border latency and bandwidth jitter. if the hong kong computer room has direct connections or excellent peering with china telecom, telecom international, china unicom, etc., the rtt and packet loss to and from the mainland will be significantly better. choosing a computer room with multi-line access and local high-quality peering can reduce the risk of single link failure and improve bandwidth stability.

select suggestions

prioritize the bgp routing policy of the computer room, whether it supports local cdn/acceleration, whether there is a list of cross-border dedicated lines and interconnection partners, and require historical link quality reports.

question 5: what verifiable performance commitments and data should suppliers be required to provide before leasing?

before signing a contract, you should request and verify: historical 30-day delay/packet loss monitoring charts, bandwidth utilization and peak records, clear terms in the sla regarding plr (packet loss rate), availability and bandwidth recovery time, as well as the maximum bearable bandwidth and switching delay during ddos cleaning. you can also ask for a trial or acceptance test based on real traffic.
