• RED - The RED (Random Early Detection) algorithm utilizes statistical
methods to drop packets in a “probabilistic” way before queues overflow.
Dropping packets in this way slows a source down enough to keep the queue
steady and reduces the number of packets lost when a queue overflows and a
host is transmitting at a high rate
Schedule By default, the class will always be active. However, scheduler rules can
be configured to define time segments during which the class may be active.
Class Rules Class rules define which packets belong to the class. They must be
defined in order to associate packets that meet them with the shaping class.
Without class rules, the shaping class will have no effect. Each class can have out-
bound and/or inbound rules for outgoing and incoming traffic, respectively. For
example, all outgoing packets from computer A in the network can be defined
as belonging to the VoIP class. These packets will be limited to the class settings
(bandwidth, schedule, etc.). In addition, the traffic protocol and priority for each
rule can be defined (this is not mandatory as it is with Traffic Priority rules).
To add a new outbound/inbound class rule, click Add in the Edit Class screen.
The “Add Traffic Priority Rule” screen appears.
Source Address - The source address of the packets sent to or received from the
network object (computer A in the above example). To add an address:
1. Select Specify Address from the drop-down list. The screen will refresh
and an “Add” link appears.
2. Click Add, and add a new network object. Note that clicking Add is equiv-
alent to clicking “New Entry” in the “Network Objects” screen.
