Network multicast serves as an efficient data transmission mechanism that achieves optimal resource-efficiency balance in one-to-many distribution scenarios, characterized by high bandwidth utilization, real-time performance, and superior scalability. In practical deployments, certain applications impose stringent reliability requirements on multicast data forwarding. This paper presents a comprehensive analysis of multicast packet loss phenomena occurring in network systems configured with domestic-brand switches. To address this critical issue, we propose: (1) an enhanced Reverse Path Forwarding (RPF) check method with improved route validation capabilities, and (2) an improved algorithm of load flow control based on token bucket-multi-level leaky bucket. Experimental evaluations demonstrate that our combined solution effectively mitigates packet loss while maintaining forwarding efficiency, thereby ensuring high-reliability multicast data delivery.
