Quality of Service (QoS)

NOTE: Quality of Service is configured on the Base Station Unit. See the Tsunami MP.11-R Installation and Management

Guide for more information.

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. QoS main priority is to guarantee a reliable and adequate transmission

quality for all types of traffic under conditions of high congestion and bandwidth over-subscription.

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
