Ehangcom Vianet Internet TG Gateway and SBC Intelligent IP Routing Scheme

When using TG Gateway or SBC for geographically distributed WAN networking, in addition to device reliability security is very important, network connectivity security is also very important. Especially when cloud services such as cloud customer service have SLA requirements, IP networks need to consider dual links or backup links to avoid access failures caused by single network operator line failures, and the SLA service requirements cannot be met. Ehangcom Vianet interconnection TG gateway and SBC products support multi-network lines. When the main line fails, it will actively switch to the backup line to ensure the reliability of the system.

Ehangcom Vianet InternetTGgateway andSBCThe product supports multiple network lines. When the main line fails, it will actively switch to the backup line to ensure system reliability. This solution supports both dual-line single-center and dual-line dual-center modes to ensure that traffic will not be interrupted due to network line failures to the greatest extent, helping the customer's system achieve the promised performance.SLAService requirements. In dual-line single-center mode, when the system detects the loss of signaling messages, it will directly switch network lines to restore traffic. In dual-line dual-center mode, when the system detects the loss of signaling messages, it will perform network line switching and center switching at the same time, solving not only network failures but also traffic interruption caused by center failures. In addition, due toTGGateway integrates powerfulCPUand generallinuxoperating system, it is easy to integrate more powerful and complexWANfunction, providing the system with something likeVPN, encryption, multi-pathing, network transmission optimization and other security and other advanced features. 1.
