QoS Class
A QoS class is defined by a set of parameters that includes the PIRs and SFCs that were previously configured.
The software allows creating up to eight different QoS classes, including four predefined QoS classes. Up to four
SF classes can be associated to each QoS class, and up to eight PIRs can be associated to each SF class. For
example, a QoS class called “G711 VoIP” may include the following SFCs: “UL-G711 20 ms VoIP rtPS” and “DL-
G711 20 ms VoIP rtPS”. In turn, the SFC named “UL-G711 20 ms VoIP rtPS” may include the following rules:
“Cisco VoIP UL” and “Vonage VoIP UL”.
The software provides the ability to create, edit, and delete QoS classes that contain the following parameters:
• QoS class name
• Service Flow (SF) class name list per QoS class (up to four SF classes can be associated to each QoS
class)
• Packet Identification Rule (PIR) list per SF class (up to eight PIRs can be associated to each SF class)
• Priority per rule which defines the order of execution of PIRs during packet identification process. The PIR
priority is a number in the range 0-63, with priority 63 being executed first, and priority 0 being executed
last. The PIR priority is defined within a QoS class, and can be different for the same PIR in some other
QoS class. If all PIRs within one QoS class have the same priority, the order of execution of PIR rules will
be defined by the order of definition of SFCs, and by the order of definition of PIRs in each SFC, within
that QoS class.
A good example of this hierarchy is provided by the four predefined QoS classes:
1. Unlimited Best Effort
a. SF class: UL-Unlimited BE
PIR: All; PIR Priority: 0
b. SF class: DL-Unlimited BE
PIR: All; PIR Priority: 0
2. G711 VoIP
a. SF class: UL-G711 20 ms VoIP rtPS
PIR: Vonage VoIP UL; PIR Priority: 1
PIR: Cisco VoIP UL; PIR Priority: 1
b. SF class: DL-G711 20 ms VoIP rtPS
PIR: Vonage VoIP DL; PIR Priority: 1
PIR: Cisco VoIP DL; PIR Priority: 1
3. G729 VoIP
a. SF class: UL-G729 20 ms VoIP rtPS
PIR: Vonage VoIP UL; PIR Priority: 1
PIR: Cisco VoIP UL; PIR Priority: 1
b. SF class: DL-G729 20 ms VoIP rtPS
PIR: Vonage VoIP DL; PIR Priority: 1
PIR: Cisco VoIP DL; PIR Priority: 1
4. 2Mbps Video
a. SF class: DL-2Mbps Video
PIR: Streaming Video (IP/TV); PIR Priority: 1
