Record-free Hong Kong serversHas been the first choice of the majority of webmasters and business users, and the stability of the line and transmission speed is an important indicator of the assessment. In the face of a rich variety of network access programs, many people have doubts about CN2 dedicated line and BGP multi-line which has the advantage of speed.
A "fast" server, like a cell phone is always lagging, making people crazy and helpless. For the pursuit of the ultimate access experience, and worried about sudden traffic surges or network attacks on enterprises and webmasters, choose the right Hong Kong server room line, is to enhance the site "running speed" and "resistance to blows" of the first lesson. Today 08Host will talk about the core differences between CN2, BGP and hybrid lines, and teach you three strokes to quickly locate the most suitable for you that "Golden Road".
First, CN2 dedicated line: Telecom direct connection, speed king?
CN2 is led by China Telecom and is known for its "direct connection to the mainland and minimal nodes".
Advantage:
- One-way latency is as low as 10ms or less, no lag in live video and video calls;
- 100% connects directly to the mainland, does not take international exports, and has a very low packet loss rate;
- Support voice, data, video and other multi-service bearer, more QoS SLA guarantee.
Shortboard:
- Smaller egress bandwidths tend to "run out" of peak traffic when budgets are limited;
- The protection ability is relatively average, and additional reinforcement is still needed when encountering heavy DDoS traffic.
Applicable Scenarios:
- The main visitors are in the continent, online entertainment, and live streaming industries that have a demanding need for low latency;
- The bandwidth elasticity requirements are not high, but the pursuit of "second open" experience of the official website of the enterprise.
Second, BGP multi-line: flexible backup, anti-failure can!
BGP is the "artery" of global operator interconnection, realizing single-IP multi-line intelligent scheduling.
Advantage:
- Multi-operator line interconnection, any one of the failure can be switched in seconds, seamless backup;
- Single IP can enjoy multiple lines bandwidth stacking, peak traffic is smoother;
- No need to take up additional resources, the system automatically selects the route, the operation and maintenance is easier.
Shortboard:
- International bandwidth paths are still subject to occasional congestion and erratic access latency;
- The advantage for the telecom-dominated CN2 direct connection is slightly less.
Applicable Scenarios:
- Websites with a balanced ratio of domestic and overseas visitors and a wide distribution of telecom/Unicom/mobile users;
- E-commerce and SaaS platforms that have requirements for high availability and continuous online presence.
Third, BGP + CN2 mixed, both offense and defense?
Hybrid lines bundle world bandwidth with direct CN2 connections, providing both multi-line redundancy and dedicated line acceleration.
Advantage:
- The CN2 portion guarantees a low latency experience for direct connections to the mainland;
- The BGP part connects multiple carriers' lines and automatically shares the overflow bandwidth;
- Failover is smoother and the availability of the whole server room is greatly improved.
Shortboard:
- After the CN2 guaranteed bandwidth is exceeded, the traffic is cut back to the international bandwidth and jitter may occur;
- Configuration and tuning are more complex, and delayed fluctuations still occur during some periods.
Applicable Scenarios:
- Growing businesses that have a concentrated visitor base on the mainland and don't want to foot the bill for sudden high traffic;
- It takes care of live broadcasting, downloading and API services, and pursues a balance between stability and speed in multiple business scenarios.
Four, three strokes to teach you to quickly choose "right"
1, analyze the distribution of visitors
- Continental share > 80%: preferably CN2;
- Overseas share > 30%: BGP is preferred;
- Mixed distribution: mixed lines are optimal solutions.
2, Evaluate bandwidth elasticity requirements
- Steady flow, low peaks: CN2 is sufficient;
- Seasonal/promotional peaks: BGP or hybrid is more flexible.
3, Consider budget and protection
- Limited budget: BGP multi-line is sufficient;
- Need to prevent DDoS: with high-defense CDN or additional defense package, and then choose CN2 or hybrid can achieve the best cost-effective.
The last thing I want to say is that there is no "absolute best" line, only the "most suitable". Choose the right line, you can let your website experience on the "second speed" mode.
