3.7.8 Setting Service Flow Information
The service flow is part of the Quality of Service (QoS) feature of the base station. Service flows provide the following
functions:
• Service flows specify a multitude of QoS parameters including: traffic priority, sustained and reserved data rates,
jitter, maximum latency, and specify security profiles.
• Service flows are setup individually for both uplink and downlink data flows.
• Service flows classify traffic based on Layer 2, 3 or 4 (Ethernet, IP, TCP/UDP/RTP) header information including
items such as source and destination addresses, port numbers, 802.1Q VLAN IDs, and Ethernet or IP traffic priority
levels.
Before each frame, OBR5000B examines all of the incoming requests and grants a time to transmit for the subscriber
station based on all of the active service flow parameters to guarantee QoS where required. Individual subscriber
stations receive aggregate bandwidth grants from the OBR5000B and must individually manage their own uplink
bandwidth usage.
Setting up a Quality of Service framework:
Step 1 Define a service class and set up its parameters.
Step 2 Define a classifier template and set up its rules.
Step 3 Create service flows and associate them with service classes and classifier templates.
Step 4 Provision subscriber stations with service flows.
To define a service class and set up its parameters:
1) Click Configuration > Service Flows > Service Classes to open the Service Class Table page. This page lists all
the default and user defined Service Classes and shows the parameters for each one.
