AI Technical Summary
Technical Problem
In data centers, when using a unified high-speed serial bus protocol, how can we implement flow control at the transmitting end to avoid buffer overflow at the receiving end, while reducing bandwidth overhead and improving communication performance?
Method used
By encapsulating credit information, including credit identifiers and virtual channel identifiers, in data packets, flow control is achieved, reducing bandwidth overhead and improving effective bandwidth and communication performance.
Benefits of technology
It effectively reduces bandwidth overhead, improves communication performance, and enables precise flow control under different transmission requirements.

Abstract
一种流量控制方法、装置及系统，涉及通信技术领域，用于在实现流量控制的同时，减小带宽开销，提高有效带宽和通信性能。所述方法包括：第一节点生成数据报文，该数据报文包括第二节点的信用信息，该信用信息用于指示返还给第二节点的虚拟通道的数据量额度，该虚拟通道用于第二节点向第一节点传输数据；第一节点向第二节点发送该数据报文；当第二节点接收到该数据报文时，对该数据报文进行解析，得到第二节点的信用信息，这样通过该信用信息实现对第二节点的流量控制。
