The QoS scheduler can -be enabled on one or more NIC output interfaces depending upon the -requirement. - - -## Overview - -The QoS scheduler supports a number of scheduling and shaping levels which -construct hierarchical-tree. The first level in the hierarchy is port (i.e. -the physical interface) that constitutes the root node of the tree. The -subsequent level is subport which represents the group of the -users/subscribers. The individual user/subscriber is represented by the pipe -at the next level. Each user can have different traffic type based on the -criteria of specific loss rate, jitter, and latency. These traffic types are -represented at the traffic-class level in the form of different traffic- -classes. The last level contains number of queues which are grouped together -to host the packets of the specific class type traffic. - -The QoS scheduler implementation requires flow classification, enqueue and -dequeue operations. The flow classification is mandatory stage for HQoS where -incoming packets are classified by mapping the packet fields information to -5-tuple (HQoS subport, pipe, traffic class, queue within traffic class, and -color) and storing that information in mbuf sched field. The enqueue operation -uses this information to determine the queue for storing the packet, and at -this stage, if the specific queue is full, QoS drops the packet. The dequeue -operation consists of scheduling the packet based on its length and available -credits, and handing over the scheduled packet to the output interface. - -For more information on QoS Scheduler, please refer DPDK Programmer's Guide- -http://dpdk.org/doc/guides/prog_guide/qos_framework.html - - -### QoS Scheduler Parameters - -Following illustrates the default HQoS configuration for each 10GbE output -port: - -Single subport (subport 0): - - Subport rate set to 100% of port rate - - Each of the 4 traffic classes has rate set to 100% of port rate - -4K pipes per subport 0 (pipes 0 .. 4095) with identical configuration: - - Pipe rate set to 1/4K of port rate - - Each of the 4 traffic classes has rate set to 100% of pipe rate - - Within each traffic class, the byte-level WRR weights for the 4 queues are set to 1:1:1:1 - - -#### Port configuration - -``` -port { - rate 1250000000 /* Assuming 10GbE port */ - frame_overhead 24 /* Overhead fields per Ethernet frame: - * 7B (Preamble) + - * 1B (Start of Frame Delimiter (SFD)) + - * 4B (Frame Check Sequence (FCS)) + - * 12B (Inter Frame Gap (IFG)) - */ - mtu 1522 /* Assuming Ethernet/IPv4 pkt (FCS not included) */ - n_subports_per_port 1 /* Number of subports per output interface */ - n_pipes_per_subport 4096 /* Number of pipes (users/subscribers) */ - queue_sizes 64 64 64 64 /* Packet queue size for each traffic class. - * All queues within the same pipe traffic class - * have the same size.

To enable HQoS on specific output -interface, vpp startup.conf file has to be configured accordingly. The output -interface that requires HQoS, should have "hqos" parameter specified in dpdk -section. Another optional parameter "hqos-thread" has been defined which can -be used to associate the output interface with specific hqos thread. In cpu -section of the config file, "corelist-hqos-threads" is introduced to assign -logical cpu cores to run the HQoS threads. A HQoS thread can run multiple HQoS -objects each associated with different output interfaces. All worker threads -instead of writing packets to NIC TX queue directly, write the packets to a -software queues. The hqos_threads read the software queues, and enqueue the -packets to HQoS objects, as well as dequeue packets from HQOS objects and -write them to NIC output interfaces. The worker threads need to be able to -send the packets to any output interface, therefore, each HQoS object -associated with NIC output interface should have software queues equal to -worker threads count. - -Following illustrates the sample startup configuration file with 4x worker -threads feeding 2x hqos threads that handle each QoS scheduler for 1x output -interface. - -``` -dpdk { - socket-mem 16384,16384 - - dev 0000:02:00.0 { - num-rx-queues 2 - hqos - } - dev 0000:06:00.0 { - num-rx-queues 2 - hqos - } - - num-mbufs 1000000 -} - -cpu { - main-core 0 - corelist-workers 1, 2, 3, 4 - corelist-hqos-threads 5, 6 -} -``` - - -### QoS scheduler CLI Commands - -Each QoS scheduler instance is initialised with default parameters required to -configure hqos port, subport, pipe and queues.
