WebRDMA over Converged Ethernet (RoCE) is a mechanism to provide this efficient data transfer with very low latencies on lossless Ethernet networks. ... While it is possible to use global flow control, this is normally undesirable, for performance reasons. The normal and optimal way to use RoCE is to use Priority Flow Control (PFC). To use PFC, it ... Web2 days ago · 采用PFC(Priority Flow Control)采用的是暂停控制帧来防止接收到过多的数据包从而引起丢包。 这种方法比起credit-based的方法，buffer的利用率难免要低一些。 由其对于一些延迟较低的交换机，buffer会相对较少，此时用PFC(Priority Flow Control)就不好控制；而如果用credit-base ...

WebRoCE (RDMA over Converged Ethernet) is a network protocol that enables low-latency, high-bandwidth data transfers between servers and storage systems. Flow control is an important feature of RoCE that helps to prevent packet … WebRDMA congestion control scheme. We aggregate flows to ease traffic uncertainty and control aggregated flows be-tween racks and individual flows within racks in different ways. 3) We implement HierCC on SystemC and verify that HierCC can significantly mitigate buffer usage and reduce the flow completion time under a realistic workload.
