Concepts and Definitions
The software supports QoS provisioning from the BSU only. You may define different classes of service on a BSU
that can then be assigned to the SUs that are associated, or that may get associated, with that BSU.
The software provides the ability to 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 17 predefined rules
• Service Flow class (SFC) – up to 32 SFs, including 7 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 4 predefined classes; up to 4 SFCs may be associated per
QoS class
Packet Identification Rule (PIR)
A Packet Identification Rule is a combination of parameters that specifies what type of traffic is allowed or
disallowed. The software allows to create up to 64 different PIRs, including 17 predefined PIRs. It provides the
ability to create, edit, and delete PIRs that contain none, one, or more of the following classification fields:
• Rule Name
• IP ToS (Layer 3 QoS identification)
• IP Protocol List containing up to 4 IP protocols
• 802.1p tag (layer 2 QoS identification)
• Up to 4 pairs of Source IP address + Mask
• Up to 4 pairs of Destination IP address + Mask
• Up to 4 source TCP/UDP port ranges
• Up to 4 destination TCP/UDP port ranges
• Up to 4 source MAC addresses
• Up to 4 destination MAC addresses
• VLAN ID
• Ether type (Ethernet protocol identification)
A good example is provided by the 17 predefined PIRs. Note that these rules help to identify specific traffic types:
1. All – No classification fields, all traffic matches
