Qos Features; Policy - Avaya X330W2-DS1 User Manual

Reassembly is associated with the following user configurable parameters:
— The number of maximum possible concurrent reassembled packets:
Min=0; Max=200; Default=100.
— The time, in seconds, to wait for a packet to be reassembled:
Min=5; Max=120; Default=10.
— The maximum number of fragments allowed per packet:
Min=2; Max=2048; Default=64.
In addition, it is possible to restore the reassembly parameters to their default
values. This discards all packets currently waiting to be reassembled.
• Access Control and QoS per interface and direction - the X330WAN supports
individual Access Control and QoS lists per interface, and per direction. This
enables the user to configure access and QoS for each direction
(transmit/receive) of each session.

QoS Features

Efficient use of QoS enables the X330WAN to assign the proper priority to different
incoming and outgoing traffic flows to minimize the affect of one flow on the other,
and to prevent a low priority traffic flow from affecting a high priority traffic flow
and the like. To achieve this, the X330WAN implements multiple receiving queues
and configurable transmitting queues (4 queues per interface).
Priority queuing is implemented among the four queues on each interface:
• Voice (highest priority)
• High priority data
• Better than best effort
• Best effort (low priority)
To insure minimal affect of one flow to the other, the following priority order (from
highest to lowest) is always maintained:
• Transmit tasks - highest priority.
• Receive tasks - medium priority.
• Router tasks - lowest priority.
Note: You can adjust the queue length for different needs. Queue length should
always be kept a small as possible, while still maintaining a flow. It is recommended
to always use the default queue length, as this is the optimal calculated length.

Policy

In the X330WAN a policy list contains:
• A set of classification rules based on a source IP, destination IP, source port,
destination port, protocol, and TCP Established bit. The IP addresses can
include wildcards.
