Table 16-9Default IP Service – Conferencing – QoS Parameters (Continued)

Field

Description

 

 

Type

DiffServ and Precedence are two methods for encoding packet

 

priority. The priority set here for audio video and IP Signaling packets

 

should match the priority set in the router.

 

• DiffServ: Select when the network router uses DiffServ for priority

 

encoding.

 

The default priorities for both audio and video packets is 0x88.

 

These values are determined by the QOS_IP_VIDEO and

 

QOS_IP_AUDIO flags in the system.cfg file.

 

The default priority for Signaling IP traffic is 0x00 and is

 

determined by the QOS_IP_SIGNALING flag in the system.cfg

 

file.

 

For more information "Modifying System Flags” on page 22-1.

 

• Precedence: Select when the network router uses Precedence

 

for priority encoding, or when you are not sure which method is

 

used by the router. Precedence should be combined with None in

 

the TOS field.

 

The default priority is 5 for audio and 4 for video packets.

 

Note: Precedence is the default mode as it is capable of providing

 

priority services to all types of routers, as well as being currently

 

the most common mechanism.

 

 

Audio / Video

You can prioritize audio and video IP packets to ensure that all

 

participants in the conference hear and see each other clearly. Select

 

the desired priority. The scale is from 0 to 5, where 0 is the lowest

 

priority and 5 is the highest. The recommended priority is 4 for audio

 

and 4 for video to ensure that the delay for both packet types is the

 

same and that audio and video packets are synchronized and to

 

ensure lip sync.

 

 

TOS

Select the type of Service (TOS) that defines optimization tagging for

 

routing the conferences audio and video packets.

 

• Delay: The recommended default for video conferencing;

 

prioritized audio and video packets tagged with this definition are

 

delivered with minimal delay (the throughput of IP packets

 

minimizes the queue sequence and the delay between packets).

 

• None: No optimization definition is applied. This is a compatibility

 

mode in which routing is based on Precedence priority settings

 

only. Select None if you do not know which standard your router

 

supports.
