Express Connect provides a secure and convenient method to connect your data center to Alibaba Cloud. You can use an Express Connect circuit provided by an Internet service provider (ISP) to connect your data center to an Alibaba Cloud access point. Connections over Express Connect circuits are not exposed to the Internet. Compared with Internet connections, connections over Express Connect circuits are safer, faster, more reliable, and have lower network latency.
You can create point-to-point Ethernet connections or multiprotocol label switching (MPLS) VPN connections. By default, connections over Express Connect circuits support the following ports: 1000BASE-LX, 10GBASE-LR, 100BASE-T, RJ45, and LC ports that support a transmission distance of up to 10 km. These ports have a transmission rate that ranges from 1 Gbit/s to 100 Gbit/s.
If the model of the copper Ethernet port that you use is obsolete, the port may not support the advanced features of Express Connect. If you use a copper Ethernet port, contact your ISP to replace the copper Ethernet port with an optical port.
Connection methods
Connections over Express Connect circuits include the following types:
Dedicated connections over Express Connect circuits
To connect your data center to Alibaba Cloud, you can use a dedicated Express Connect circuit from an ISP. You can apply for a dedicated Express Connect circuit in the Express Connect console. For more information, see Create and manage a dedicated connection over an Express Connect circuit.
Hosted connections over Express Connect circuits
The access points of Express Connect partners are already connected to the access points of Alibaba Cloud. You can contact an Express Connect partner to use a hosted connection over an Express Connect circuit. In this case, the connection is shared by multiple tenants. For more information, see Operation guide for Express Connect partners.
Query the locations of access points
Before you can query the locations of access points, you must apply for the quota whose name and ID are ec_can_get_pconn_address and q_db41hu in the Express Connect console or Quota Center. Wait 10 to 15 minutes after you submit the application because the system needs to refresh the cache. For more information about how to apply for a quota increase, see the Adjust quotas section of the "Manage Express Connect quotas" topic.
You can query the access points of only dedicated Express Connect circuits.
Before you query the locations of access points, make sure that a dedicated Express Connect circuit is installed. For more information, see Create and manage a dedicated connection over an Express Connect circuit.
You can use one of the following methods to query the locations of access points in the Express Connect console:
View the location of an access point on the Physical Connection page.
