This topic describes the preparations that you must make before you establish an exclusive physical connection.
1. Select an access point
An access point is a location where Alibaba Cloud provides network services. Multiple links are available at access points for you to access Alibaba Cloud. Before you access Alibaba Cloud through a physical connection, you must to obtain the detailed location of the access point.
We recommend that you select an access point that is closest to your on-premises data center. Access points in different regions belong to different data center providers and have different bandwidths.
- Service provider
We recommend that you select a service provider based on your needs. Available service providers include China Unicom, China Telecom, China Mobile, and some local service providers.Note
- Data centers of all access points are owned by service providers and third-party providers except the Hangzhou-Yuhang-A-Ali access point and the access points in the China (Zhangjiakou) region.
- Data centers of China Unicom, China Telecom, and China Mobile only allow access from their own leased lines and do not support leased lines of other service providers.
- In principle, China Unicom, China Telecom, and China Mobile data centers do not support access from bare fibers. For more information, consult the service provider.
You can select an electrical port or an optical port.
- All electrical ports use MSTP links. Service providers use optical transceivers to
convert optical cables of the transmission network to low-bandwidth RJ45 interfaces
in data centers where access points are located. According to the industry standard,
RJ45 interfaces are usually used for ports with a speed lower than 100 Mbit/s. Therefore,
we recommend that you use a 100M electrical port if you need a low bandwidth.
The switches at Alibaba Cloud access points support 10 GE electrical ports by default. The port speed depends on the port specification.
- Optical ports are commonly known as bare optical fibers. Service providers directly
use optical cables of the transmission network for you to connect to Alibaba Cloud.
Theoretically, the speed of an optical port is unlimited. It depends on the negotiated
speed of optical modules at both ends of the connection and can be 1G, 10G, 40G, or
- Different access points provide different port types. We recommend you check the port types available for purchase before you apply for a physical connection interface.
- By default, Alibaba Cloud provides optical modules with 1G and 10G ports and a transmission distance of 10 km. If you need optical modules with 40G and 100G ports and a longer transmission distance, you must purchase the optical modules yourself.
- If you select an optical port, make sure that the service provider of the leased line uses optical fiber cables to access Alibaba Cloud devices.
- Alibaba Cloud does not host any fiber optical transceivers for customers. Make sure that the leased line provider uses the correct type of cables to access Alibaba Cloud devices.
- All electrical ports use MSTP links. Service providers use optical transceivers to convert optical cables of the transmission network to low-bandwidth RJ45 interfaces in data centers where access points are located. According to the industry standard, RJ45 interfaces are usually used for ports with a speed lower than 100 Mbit/s. Therefore, we recommend that you use a 100M electrical port if you need a low bandwidth.
2. Check available resources
After you select the access point, service provider, and port type, you can check whether the resources you require are available for purchase by going to the payment page in the Express connect console.
- Go to the physical connection interface purchase page.
- Select the access point, port type, port specification, and other required parameters and click Buy Now.
- Check the configurations of the physical connection interface and click Pay.
- Check the message displayed on the page.
- If after you click Pay, a payment page appears, it means the resources you require are available at the
selected access point.
Notice Do not click Confirm Payment.
- If after you click Pay, a message that says the activation failed appears, it means the resources you require are unavailable for purchase at the selected access point. We recommend that you select another access point.
- If after you click Pay, a payment page appears, it means the resources you require are available at the selected access point.
3. Contact the service provider to perform a site survey
After you determine the access point and obtain the location of the access point, you must contact the service provider for a connection solution and ask the service provider to perform a site survey.
- Contact your service provider, ask the service provider to connect your on-premises data center to the selected Alibaba Cloud access point, and ask for a leased line connection plan.
- After you and your service provider determine the connection plan, you must to apply
for a site survey at the data center where the Alibaba Cloud access point is located.
You must provide required information, including names, IDs, and contact information of the service provider engineers who will perform the site survey.
- After your application is approved, Alibaba Cloud will help the engineers perform the site survey within two workdays.
- Contact the service provider to perform the site survey and ask for a price quote
for end-to-end resources. Fees involved include:
- Alibaba Cloud charges a one-time initial installation fee and a resource occupation fee for the port you use.
- The service provider charges a rental fee for the leased line used to connect your on-premises data center to the access point.
- The data center provider may charge an indoor cable fee. Data centers of all access points are owned by service providers and third-party providers except the Hangzhou-Yuhang-A-Ali access point and access points in China (Zhangjiakou), which are owned by Alibaba Cloud. Therefore, you may need to purchase indoor cables at the data center building from the data center provider.
- The provider of your on-premises data center may charge fees for cable connections
and use of indoor cables.
Note Before your service provider performs the site survey at Alibaba Cloud access point, note the following:
- For data centers within Mainland China, the service provider can apply to enter the room dedicated to Alibaba Cloud devices for a site survey.
- For data centers outside Mainland China, the service provider does not need to enter the dedicated room of Alibaba Cloud and only needs to perform the site survey at the Meet-Me-Room. Therefore, site surveys outside Mainland China do not require applications or approvals by Alibaba Cloud.
- To obtain the detailed location of the Alibaba Cloud access point, open a ticket.
