2.4  QoS 

Quality of Service (QoS) is the ability to provide different priority to different applications, users, or data flows. QoS 
guarantees a certain level of performance to a data flow by using the following metrics: transmitted bit rate, bit error 
rate,  delay,  jitter,  and  probability  of  packet  dropping.  QoS  guarantees  are  important  if  the  network  capacityis 
insufficient, especially  for application  that  requires certain bit rate and is delay  sensitive.  For any  network that is 
best effort, QoS cannot be guaranteed, except that resource is more than sufficient to serve users.  
 
Controlling network traffic needs a set of rules to help classify different types of traffic and define how each of them 
should be treated as they are being transmitted. This managed switch can inspect both 802

.

1p Class of Service 

(CoS) tags and DiffServ tags called Differentiated Services Code Point (DSCP) to provide consistent classification. 
Under the 

QoS

 section, there are four subsections: 

Setting

 subsection, 

CoS Queuing Mapping 

subsection, 

DSCP 

Mapping

 subsection and Strom control subsection, as shown in Figure 2.54

2.4.1.1 

QoS Setting 

Two modes of QoS or packet scheduling methods are configurable in EH75XXseries managed switch: Strict Priority 
only and Deficit Weighted Round

-

Robin (DWRR) with Strict Priortly.  

In 

Strict Priority

, the QoS scheduler allows the highest priority queue to preempt other queues as long as there 

are  still  packets  waiting  to  be  transmitted  in  the  highest  priority  queue.  This  mode  guarantees  that  traffic  in  the 
highest queue is always transmitted first. Only if the high priority queues are empty, the lower priority queues can 
be  transmitted.  Queue  0  (Q0)  to Queue  7  (Q7)  are  ranked  from  the  lowest  priority  queue  to  the  highest  priority 
queue. Therefore, packets in Q7 will be all transmitted first before packets in Q6, and packets in Q6 will all be sent 
first before packets in Q5, and so on in this order.  

Weighted Round Robin (WRR) 

is the simplest approximation of generalized  processor sharing (GPS). In WRR, 

each packet flow or connection has its own packet queue in a network interface controller

. 

It ensures that all service 

classes have access to at least some configured amount of network bandwidth to avoid bandwidth starvation. But 
WRR has a limitation, as it is unfair with variable length packets. It only provides the correct percentage of bandwidth 
to each service class only if all of the packets in all the queues are the same size or when the mean packet size is 
known in advance. Usually,  a weight of each queue is set proportion to requested bit rate. Each queue is served 
proportionally to its weight for a service cycle. 

 
Deficit WRR (DWRR) 

addressed the limitation of WRR on unfairness over variable size. Each queue is configured 

with a weight, a deficit counter (total number of bytes that the queue is permitted to transmit each time visited by 
the scheduler), and a quantum of service (bytes). DWRR scans all non-empty queues in sequence. When a non

-

empty  queue  is  selected,  its  deficit  counter  is  incremented  by  its  quantum  value.  Then,  the  value  of  the  deficit 
counter is the maximal number of bytes that can be sent at this turn. If the deficit counter is greater than the packet

’s 

size at the head of the queue, this packet can be sent and the value of the counter is decremented by the packet 
size. Then the size of the next packets is compared to the counter value. Once the queue is empty or the value of 
the counter is insufficient, the scheduler will skip to the next queue

.  

If the queue is empty, the value of the deficit 

counter is reset to 0. If the packet size is too small, the scheduler has to visit queues too many times before serving 
a queue. But if the packet size is too large, some short-term unfairness may arise. It is fair only over a time scale 
longer than a round time. At the shorter time scale, some flows may get more service. Small packet size or high 
transmission speed reduce the round time.
