Fast, secure and stable dedicated network with low latency for optical fiber communications
Tencent Cloud Direct Connect (DC) enables you to connect your corporate IDC with Tencent Cloud more conveniently by establishing a private connection that is completely isolated from public networks. Compared with public networks, DC is more secure and stable with lower latency and greater bandwidth. All you need is to set up one Connection from your ISP to Tencent Cloud, and then you can quickly create multiple DC tunnels to take advantage of the computation resources deployed in Tencent Cloud. This configuration enables a flexible and reliable deployment of hybrid cloud. In many cases, the flexible billing modes of the DC tunnels can also lower you costs for DC usage.
Tencent Cloud DC guarantees over 99.5% stable network latency. By setting a fixed route configuration, you can speed up the access to and download from business data nodes, eliminating the unstable latency caused by network congestion or fault bypassing and improving your connection speed and network experience.
Tencent Cloud DC access devices and network forwarding devices are distributed in clusters for deployment, and the specifications of these devices are highly reliable. Dual line access is also supported. The guaranteed professional-grade network reliability ensures that your applications run smoothly and fully meet your needs for over 99.95% network availability.
Tencent Cloud DC supports up to 10Gbps bandwidth with one single connection line. In addition, a theoretically unlimited number of 10Gbps links can be added for network load balancing. DC can automatically distribute traffic, allowing for smoother cross-business access and operations.
The large-bandwidth network connectivity provided by Tencent Cloud DC features exclusivity and a peak level of security. The network link is exclusive only for your own businesses, so you don't need to worry about data leakage. This solution is ideal for clients that require high security levels such as financial institutions, government agencies and large corporations.
Tencent Cloud DC supports the configuration of NAT service on the gateway, enabling you to interconnect among multiple local IDCs. IP mapping between both ends of DC as well as IP port mapping on VPC are supported, which provides a perfect solution to the problem of address conflicts when connecting to third-party networks.
"Tencent Cloud DC provides you with a highly reliable SLA. In addition, it has best-in-class access availability (up to 99.5% for single-line access and 99.95% when accessing from dual line dual access point) to meet your demands for network connectivity.
Note: DC availability is that of the connection from the DC access point to the Tencent Cloud VPC, while the availability of the network connection between the access point and your IDC is provided by the ISP of the connection."
Tencent Cloud DC supports VLAN tagging. After activating VLAN on one single DC line for connection to Tencent Cloud, multiple DC tunnels can be established. These tunnels can then be connected to private networks in different regions around the globe through Tencent Cloud's three-layer MPLS network. This configuration enables secure and reliable network communication that can meet your ever-growing requirements for global deployment.
Tencent Cloud DC supports four types of access ports, including 100Base-T, 1000Base-T, 1000Base-LX and 10GBase-LR, and a variety of access protocols such as MSTP, SDH, OTN and DWDM, fully satisfying your wide-ranging demands for network access.
To meet the demand for highly reliable network access, Tencent Cloud DC boasts dual access point availability through which you can connect to Tencent Cloud in a large number of cities around the world. Tencent Cloud supports two DC backup configuration modes, i.e. traffic sharing (load balancing) and master/slave switch upon failure.
Tencent Cloud DC supports the configuration of NAT service on the gateway, enabling you to interconnect among multiple local IDCs. IP mapping at both ends of DC and IP port mapping on VPC are supported, which provides a perfect solution to the problem of address conflicts when connecting to third-party networks. Three mapping methods are supported, i.e. one-to-one mapping of the source IP address and destination IP address, source address pool translation of VPC and port mapping of VPC.
For application scenarios where backup is required, you can realize the communications between VPC and your IDC through Connection, and then back up the data by dual line access or VPN access. The IP address range overlap between the VPC and the IDC does not affect communications.
DC consists of two components: the Connection and Dedicated Tunnel.
Connection: One-time charge of 2,500 USD, including port fees and testing service fees, Monthly Rental Charge is under planning, which you won't be charged until the plan published.
Dedicated Tunnel: Monthly charge in postpaid manner. Intra-city access is free of charge, while inter-city access is a paid service. For details, see here.
