This section describes the product advantages of CDA, such as secure bearing, stability and high efficiency, flexible access and convenient management. With these advantages, CDA creates a high-quality service experience for you.

Secure Bearing

Users can access the VPC on the cloud through CDA and monopolize a network link for communication with resources on the cloud to avoid data leakage. This allows transparent bearing of upper-layer integrated applications such as data, voice, and video. Users can opt to monopolize a physical port for data transmission to achieve physical isolation from the service data of other users. Alternatively, users can share physical lines with other users to achieve logical isolation of service data. This guarantees the security of user data transmission and saves the cost of dedicated lines for the user.

Stable and Efficient

Relying on the high-performance network layout of eSurfing Cloud, CDA uses a dedicated network to transmit data. This avoids the uncertain latency caused by link congestion or fault bypass, improves the data transmission rate, reduces network delays, and provides carrier-grade high-quality network support.

In addition, the CDA service provides a redundancy solution and supports two access modes: link load and primary/standby. Users can effectively separate management traffic from service traffic through customized routing policies and automatic link switching is triggered when a link failure occurs to further guarantee the smooth operation of services.

Flexible Access

eSurfing Cloud has rich link resources and provides dedicated lines of multiple types such as IPRAN, MSTP, MPLS VPN, and OTN. Users can flexibly select different dedicated line access modes according to their business requirements. Each access mode can be used with Internet access at the same time to adapt to the geographical locations and environmental conditions of various access scenarios of users. In addition, it can meet the various networking needs of users and facilitate convenient networking.

Convenient Management

eSurfing Cloud provides a unified network management console. Users can log in to the CDA product console on the official website of eSurfing Cloud to conveniently manage the enabled CDA service. Through the console, users can modify the basic information about dedicated physical lines, change the subnet interworking between the client side and the VPC side with one click, and monitor the upstream and downstream traffic of the dedicated physical lines in real time, thus simplifying users' operation, maintenance and management.

Controllable Cost

Users can select different specifications of dedicated lines and access modes according to business requirements.
