Sino-Telecom AI switch provides the following features and benefits:
Built with domestically developed chips, the SR3864 ensures full-stack autonomy from silicon to system, delivering enhanced information security and supply chain assurance for mission- critical industries.
Leverages advanced congestion management and flow control algorithms based on Priority Flow Control (PFC) and Explicit Congestion Notification (ECN). Combined with precise latency monitoring and telemetry, the SR3864 meets the stringent requirements of AI network architectures.
Powered by an in-house developed VCCL collective communication library and proprietary Deep- Routing technology, the switch optimizes parameters for intelligent computing scenarios, boosting collective communication performance by up to 50% during large-scale model training.
Supports high-efficiency packet-based multipath transmission, distributing packets across multiple paths for fine-grained load balancing. Compared to traditional flow-based methods (e.g., ECMP), traffic spraying offers superior network resource utilization and performance under dynamic workloads.
Enables millisecond-level traffic statistics and AI workload analysis via built-in agents that collect real-time traffic data and transmit it to the central management platform. This ensures complete traffic visibility and intelligent traffic regulation across the network.
The first 8 ports of the switch support native ZR/ZR+ optics, enabling seamless long-haul connectivity. This eliminates the need for DCI-layer conversions between optical and electrical domains, significantly reducing cost, complexity, and points of failure in city-scale computing interconnect solutions.
The Venus AI NOC is an integrated network management platform purpose-built for intelligent computing centers. It offers centralized control, automated deployment, real-time monitoring and analytics, and multi-tenant management, delivering a comprehensive and efficient solution for AI data center networks.
