Webbration (shared buffer ECN/RED) at commodity switches. BCC operates based on real-time shared buffer utiliza-tion. When the buffer is abundant,BCC delivers both high throughput and low packet loss rate. When it be-comes scarce, BCC triggers shared buffer ECN/RED to prevent packet losses at the cost of sacrificing a small amount of throughput. WebbI have an application running with N nodes sending traffic with N * M BulkSendSApplication instances to a main node through a switch. This is working well. I would like to simulate a buffer on the switch so if there is a burst, the packets that cannot be sent at the moment will be stored and sent later.

Webb13 juni 2024 · 8MB shared buffer(or even 9MB shared buffer with Dell switches) is the limiting factor so fairness to other flows is a consideration (i.e. not too aggressive with DWRR weights). Some caveats, if using TCP with iSCSI and packets are dropped; this will impact performance. (which may not be an issue.)
