BFEM leverages the shared buffer to reduce packet loss and meanwhile punishes aggressive flows by ECN marking. We evaluate BFEM with both 40Gbps P4 testbed implementation and large-scale NS2 …
Webb16 nov. 2024 · The following are the problems that might occur in the Producer-Consumer: The producer should produce data only when the buffer is not full. If the buffer is full, then the producer shouldn't be allowed to put any data into the buffer. The consumer should consume data only when the buffer is not empty. If the buffer is empty, then the … WebbINPUT-BUFFERED SWITCHES When high-speed packet switches were constructed for the first time, they used either internal shared buffer or input buffer and suffered the problem of throughput limitation. As a result, most early-date research has focused on the output buffering architecture.
