Configuring Services Settings 109

P0910464 Issue 01 Enterprise Edge Networking Operations Guide

The QoS Services Summary settings are:

Setting Definition

Description Shows the description of the QoS provider.

Version Shows the driver version of the QoS provider.

Status Lets users enable or disable the QoS module.

Premium

Bandwidth

Lets users specify, in percentages, the WAN bandwidth reserved for premium

traffics.

Choose a value for this field based on the link speed, the codecs used by VoIP

gateway, the sample rate and the number of concurrent phone calls (from

internal VoIP gateway) and other H.323 sessions (like Microsoft NetMeeting

traffic) you intend to carry over the WAN link. Refer to WAN overview

page 37 for more information on this topic.

Make sure you allocate at least the bandwidth necessary to carry as many

phone calls as specified in 'Number of Phone Ports' field below. Otherwise,

the QoS provider sees the inconsistent configuration and disables itself when

system boots next time, resulting in broken connectivity.

Any additional bandwidth that is more than what is required to carry the

phone calls is available for other H.323 sessions like NetMeeting sessions

from PCs connected to Enterprise Edge box or other data traffic classified as

premium, through QoS Filters. This additional bandwidth reserved for

premium traffic is always available for other data traffic if there is no

additional H.323 traffic or other premium traffic.

A network administrator can reserve more WAN bandwidth than that required

to carry phone calls and then prevent PC users from using it for NetMeeting

sessions by setting filters that drop H.323 traffic at LAN interfaces.

Video Class Lets users specify the type of priority treatment for video traffic in H223

sessions.

The following choices are available:

Premium: Video traffic is treated as premium traffic that consumes portions of

bandwidth reserved for premium traffic (Premium Bandwidth field).

Best Effort: Video traffic is treated as best effort IP traffic that are prioritized

among other best-effort traffic passing through the WAN link.

Premium DS

Code

Lets users specify the TOS field in the IP header for premium packets.

This value is used in conjunction with the frame relay driver in Enterprise

Edge's WAN link, if one is being used, as well as rest of the network.

If the frame relay is used on WAN link, this code should match the DS Code

field in frame relay settings so that frame relay network treats this traffic as

high-priority.

If rest of the network is diffserv capable, all routers that carry VoIP traffic

from theEnterprise Edge server must be configured to treat the traffic with this

DS code as high-priority or premium traffic.

Number of Phone

Ports

Lets users specify the number of phone ports.

This value specifies the number of concurrent phone calls user intends to carry

over the WAN interface. QoS Provider layer uses this value to determine how

much of the bandwidth reserved for premium traffic is consumed by internal

VoIP gateway and how much is left over for other H.323 or other classified

premium traffic.

Filter Order Lets users specify the order that filters are evaluated. If a filter name is listed

in filter order, but the actual filter is missing, it is ignored. If an actual filter is

omitted from the filter order list, the filter is not effective.
