What are Session Border Controllers (SBC) in China?
Session Border Controllers (SBCs) are network devices or software solutions that manage and secure real-time communication sessions, such as Voice over IP (VoIP) calls, video conferencing, and other multimedia exchanges, particularly between different networks. SBCs are deployed at the borders of networks, typically between an enterprise and a service provider network, to protect the communication infrastructure and optimize traffic flow. Their primary functions include session signaling, traffic routing, encryption, and ensuring secure interconnection between different communication systems. SBCs handle tasks like ensuring high-quality service (QoS), mitigating security threats (such as denial-of-service (DoS) attacks and eavesdropping), and maintaining compliance with industry standards.
