Scenario Solutions



Multi-Link Load Balancing

Ensures proper traffic distribution in the multi-link network environment, increases bandwidth utilization rates, helps customers to reduce investment in telecommunication links and offers excellent access experience by assigning the best link to users and application systems.  

Server Load Balancing

Establishes an efficient health check and load balancing mechanism on the server, with no changes to the existing network. Provides a cost-effective and transparent error tolerance method to increase the equipment and server's bandwidth as well as throughput, improve data processing capability and enhance network flexibility & availability. 

SSL offloading for HTTPS services

Sangfor AD SSL off-loading is capable of mitigating performance load and increase server response via transferring SSL decryption process to Sangfor AD from server.


Multi-Data Center Load Balancing

Assigns users' access requests to the corresponding data center based on preset rules, which ensures proper distribution of data flows and makes fully use of all data centers. Improves the overall processing capability and stability of the application system and enhance users' access experience, thus reducing the customers' IT investment costs.

Virtualized Data Center Load Balancing

Releases the computing resources in the ESXi host when SANGFOR's AD product is deployed with the VMware vSphere. On the other hand, the vSphere ensures the high availability of the application and moreover, puts the Virtualization technology into full play.
