+# Quality-of-Service (QoS)- Hierarchcal Scheduler
+
+The Quality-of-Service (QoS) scheduler performs egress-traffic management by prioritizing the transmission of the packets of different type services and subcribers based on the Service Level Agreements (SLAs). The QoS scheduler can be enabled on one or more NIC output interfaces depending upon the requirement.
+
+## Overview
+
+The QoS schdeuler 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 Schdeuler 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

+### DPDK QoS Scheduler Integration in VPP
+
+The Hierarchical Quaity-of-Service (HQoS) scheduler object could be seen as part of the logical NIC output interface. 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.

+### QoS scheduler CLI Commands
+ Each QoS scheduler instance is initialised with default parameters required to configure hqos port, subport, pipe and queues. Some of the parameters can be re-configured in run-time through CLI commands.
+
+#### Configuration
+ Following commands can be used to configure QoS scheduler parameters-
+
+ * The command below can be used to set the subport level parameters such as token bucket rate (bytes per seconds), token bucket size (bytes),
+ traffic class rates (bytes per seconds) and token update period (Milliseconds).
+ set dpdk interface hqos subport <if-name> subport <n> [rate <n>] [bktsize <n>] [tc0 <n>] [tc1 <n>] [tc2 <n>] [tc3 <n>] [period <n>]
+
+ * For setting the pipe profile, following command can be used.
+ set dpdk interface hqos pipe <if-name> subport <n> pipe <n> profile <n>
+
+ * To assign QoS scheduler instance to the specific thread, following command can be used.
+ set dpdk interface hqos placement <if-name> thread <n>
+
+ * The command below is used to set the packet fields required for classifiying the incoming packet. As a result of classification process,
+ packet field information will be mapped to 5 tuples (subport, pipe, traffic class, pipe, color) and stored in packet mbuf.
+ set dpdk interface hqos pktfield <if-name> id <n> offset <n> mask <n>
+
+ * The DSCP table entries used for idenfiying the traffic class and queue can be set using the command below;
