Network and solution requirements
This section provides a list of requirements for optimizing video within your network.
Design and deploy a multimedia QoS policy.
The Avaya one-X
®
Communicator, the AVCS 1000-series video endpoints, the Avaya A175
Desktop Video Device, and all Polycom conferencing devices support QoS for video. For more
information, see the checklist in section 11.0 of the white paper from Polycom Global Services
titled Supporting Real-time Traffic: Preparing Your IP Network for Video Conferencing.
The following checklist can be used to determine how well your network is prepared for a voice
and video implementation.
● Identify real-time bandwidth demand by link.
● Identify data bandwidth demand by link (utilization).
● Assess available bandwidth by link, and upgrade as necessary.
● Determine enterprise QoS classification approach.
● Determine enterprise QoS technology for the networks (LAN).
● Determine enterprise QoS technology for the WAN and select WAN vendors.
● Verify WAN support for enterprise QoS approach through testing.
● Deploy QoS in all portions of the network supporting real-time traffic.
● Verify network support of real-time traffic with synthetic testing.
● Implement a bandwidth management methodology.
● Implement real-time network monitoring capability.
● Create, negotiate, and sign an enterprise SLA.
Selecting a default enterprise maximum call rate.
Avaya recommends an initial deployment rate of 384 kbps. Keep in mind the following caveats:
● 20% allocation for IP protocol overheads
● High-definition room systems support call rates of 4 Mbps.
For procedures to set the call rate for normal and priority users, see
