Which route fits?

Answer a few questions about your traffic and locations: you get the option that fits, an alternative and what to know about ICP filing.

Where are your users or sites outside China?
What does this traffic need?
How many locations need connecting?
Will you serve content from inside mainland China?

Recommended

IP Transit

Full routing-table reach into mainland China over a Chinese carrier backbone (AS4837 · AS10099).

Alternative

CloudBond — premium China routing (AS9929)

Consider it if this traffic needs a cleaner, premium path into China.

Ask us for current specifications.

ICP filing

If any content will be hosted inside mainland China, plan for an ICP filing through your CDN or host. We help you scope the steps with your counsel; this is not legal advice.

How this works and its limits

Runs in your browser: your answers stay on your device and are never uploaded.

The options run from the public internet up to private lines. Two answers set the smallest option that fits: what the traffic needs, and whether several locations must be linked. Your starting region does not change the option; it tells us where to look for the nearest delivery point.

The result is a starting point, not a quote or a performance promise. A route assessment confirms the option for your city pairs, and China circuits are quoted after it.

The tool asks four things: what the traffic needs, how many locations must be linked, whether you will serve content from inside mainland China, and where you start from. It does not know your budget, contract term, existing capacity or the applications you run. The result names the option to check in the assessment; the assessment confirms it. The alternative is the next step up or the lighter option that still fits.

From the public internet to private lines

The public internet is the baseline every option improves on. IP Transit carries your traffic on a Chinese carrier backbone, with full routing-table reach into mainland China (AS4837 · AS10099).

CloudBond — premium China routing (AS9929) carries traffic that needs a cleaner path, such as games, live video and APIs; measured figures for your city pair are available on request. DIA and SD-WAN on a carrier-backed underlay suit several locations that need internet access and centrally managed, multi-path networking.

IEPL and IPLC are point-to-point international private lines: IPLC (International Private Leased Circuit) is a dedicated Layer 1 circuit, and IEPL (International Ethernet Private Line) hands off Ethernet at each end. They fit fixed, dedicated bandwidth between your sites and China, with availability terms set out in your agreement.

Compare quotes on the same city pair, bandwidth and term. A transit quote is priced on capacity and commit; a private line on distance and bandwidth. Add local access, installation, any cross-connect and the router at each end to both sides before you compare the monthly figure.

Ask every provider the same four questions: where the traffic enters the mainland, which AS path it takes, what latency and loss baseline is measured for your city pair, and what happens to routing when a path fails. Those answers decide more than the headline bandwidth.

For IP transit, check the handoff and the BGP session: prefix filters, a maximum-prefix limit, and whether you announce your own address space or take provider-assigned addresses. For private lines, check the demarcation, the protection and the bandwidth granularity you can grow into.

Serving content from inside mainland China also needs an ICP filing and local hosting, which your CDN or host handles. We help you scope the steps with your counsel; this is not legal advice.

FAQ

Why is the public internet never the recommendation?
It is the baseline the other options improve on. We recommend one of the services we deliver, from IP Transit on a Chinese carrier backbone up to private lines.

Does the tool check my sites or traffic?
No. It uses only your answers, in your browser. A route assessment looks at your actual sites, bandwidth and city pairs.

Do I need an ICP filing?
Only for websites hosted inside mainland China; the filing goes through your hosting or CDN provider. We help you scope the steps with your counsel; this is not legal advice.

What is DIA, and when is it the right choice?
Dedicated internet access is business-grade internet access at a committed rate, as opposed to best-effort broadband. It suits an office, factory or store that needs ordinary internet access plus a predictable uplink; it does not replace a private line for traffic that must avoid the public internet. DIA has the definition.

Can we combine options?
Yes, and most networks do: a private line for the traffic that must be predictable, internet access or transit for everything else, and SD-WAN to steer between them. You can start with one option and add another when a new site or application needs it.

Why does my region not change the recommendation?
Because the options are delivered from many regions; the region changes the nearest delivery point and the path your traffic takes, not the option that fits. That is why the tool asks it last and uses it only for the delivery line.

What does the route assessment add?
It looks at your actual sites, bandwidth, city pairs and applications, confirms the delivery point, and puts the option and its terms in a quote.
