Currently, it supports RED for active queue management (which is designed \nto control the queue length but it does not control latency directly and is now being \nobsoleted). However, more advanced queue management is required to address this problem\nand provide desirable quality of service to users.\n\nThis solution (RFC) proposes usage of new algorithm called \"PIE\" (Proportional Integral\ncontroller Enhanced) that can effectively and directly control queuing latency to address \nthe bufferbloat problem.\n\nThe implementation of mentioned functionality includes modification of existing and \nadding a new set of data structures to the library, adding PIE related APIs. \nThis affects structures in public API/ABI. That is why deprecation notice is going\nto be prepared and sent.\n\nLiguzinski, WojciechX (5):\n sched: add PIE based congestion management\n example/qos_sched: add PIE support\n example/ip_pipeline: add PIE support\n doc/guides/prog_guide: added PIE\n app/test: add tests for PIE\n\n app/test/autotest_data.py | 18 +\n app/test/meson.build | 4 +\n app/test/test_pie.c | 1065 ++++++++++++++++++\n config/rte_config.h | 1 -\n doc/guides/prog_guide/glossary.rst | 3 +\n doc/guides/prog_guide/qos_framework.rst | 60 +-\n doc/guides/prog_guide/traffic_management.rst | 13 +-\n drivers/net/softnic/rte_eth_softnic_tm.c | 6 +-\n examples/ip_pipeline/tmgr.c | 6 +-\n examples/qos_sched/app_thread.c | 1 -\n examples/qos_sched/cfg_file.c | 82 +-\n examples/qos_sched/init.c | 7 +-\n examples/qos_sched/profile.cfg | 196 ++--\n lib/sched/meson.build | 10 +-\n lib/sched/rte_pie.c | 86 ++\n lib/sched/rte_pie.h | 398 +++++++\n lib/sched/rte_sched.c | 228 ++--\n lib/sched/rte_sched.h | 53 +-\n lib/sched/version.map | 3 +\n 19 files changed, 2050 insertions(+), 190 deletions(-)\n create mode 100644 app/test/test_pie.c\n create mode 100644 lib/sched/rte_pie.c\n create mode 100644 lib/sched/rte_pie.h" }
