I am exploring way to resolve the noisy neighbor syndrome using guaranteed minimum bandwidth(when the neighbors are consuming egress traffic, which could be throttled in favor of the guaranteed port).
With current implementation(based on rte_meter.h),with CIR specified in terms of percentage of interface bandwidth, indicating the guaranteed bandwidth and sum of all CIR not exceed the total bandwidth of the interface, wold that be the right way of ensuring guaranteed bandwidth and avoid the noisy neighbor syndrome. It would be also wonderful to hear thoughts around Hierarchical Scheduler library (rte_tm.h,rte_mtr.h), with its support for Traffic shaping for pipes and subports, hierarchical scheduling, congestion management, packet marking and implementation in either HW, SW or hybrid mode. Would that be the direction ovs dpdk be moving towards. Kind Regards yogananth
