Abstract Hierarchical Packet Fair Queueing Algorithms

WebWe design Hierarchical Packet Fair Queueing (H-PFQ) algorithms to approximate H-GPS by using one-level variable-rate PFQ servers as basic building blocks. By computing the system virtual time and per packet virtual start/finish times in unit of bits instead of seconds, most of the PFQ algorithms in the literature can be properly defined as variable-rate … WebModified schedulers preserve guarantees close to the original ones, and can also handle seamlessly both leaves and internal nodes in a hierarchical setting. We also present Quick Fair Queueing Plus (QFQ+), a fast fair-queueing scheduler that we defined using this scheme, and that is now in mainline Linux. cinthia angus volleyball
