4.6 Quality of Service (QoS) Configuration
The Quality of Service (QoS) feature is based on the 802.16 standard and defines the classes, service flows, and packet
identification rules for specific types of traffic.
4.6.1 QoS Concepts and Definitions
The software supports QoS provisioning from the End Point A only. You may define different classes of service on a End Point
A that can then be assigned to the End Point B that is associated, or that may get associated, with that End Point A.
You can create, edit, and delete classes of service that are specified by the following hierarchy of parameters:
• Packet Identification Rule (PIR) – up to 64 rules, including 18 predefined rules
• Service Flow class (SFC) – up to 32 SFCs, including 8 predefined SFCs; up to 8 PIRs may be associated per SFC
• Priority for each rule within each SF class – 0 to 255, with 0 being lowest priority
• QoS class – up to 8 QoS classes, including 5 predefined classes; up to 8 SFCs may be associated per QoS class
4.6.1.1 Packet Identification Rule (PIR)
A Packet Identification Rule is a combination of parameters that specifies what type of traffic is allowed or disallowed. You
can create up to 64 different PIRs, including 18 predefined PIRs. Also, you can create, edit, and delete PIRs that contain none,
one, or more of the following classification fields:
• Rule Name
• IP ToS (Layer 3 QoS identification)
• 802.1p tag (layer 2 QoS identification)
• IP Protocol List containing up to 4 IP protocols
• VLAN ID
• PPPoE Encapsulation
• Ether Type (Ethernet Protocol identification)
• Up to 4 TCP/UDP Source port ranges
• Up to 4 TCP/UDP Destination port ranges
• Up to 4 pairs of Source IP address + Mask
• Up to 4 pairs of Destination IP address + Mask
• Up to 4 source MAC addresses + Mask
• Up to 4 destination MAC addresses + Mask
NOTE: IP Address, TCP/UDP Port, MAC Address need to be configured separately and associate those classification in
PIR details if required.
A good example is provided by the 18 predefined PIRs. Note that these rules help identify specific traffic types:
1. All – No classification fields, all traffic matches
2. L2 Multicast
a. Ethernet Destination (dest = 0x010000000000, mask = 0x010000000000)
3. L2 Broadcast
a. Ethernet Destination (dest = 0xffffffffffff, mask = 0xffffffffffff)
4. Cisco VoIP UL
a. TCP/UDP Source Port Range (16,000-33,000)
b. IP Protocol List (17 = UDP)
5. Vonage VoIP UL
