Chapter 2: Planning your Avaya Scopia® XT

Desktop Deployment

When planning your Avaya Scopia® XT Desktop deployment, consider the following:

• Will most Scopia® XT Desktop Clients connect to videoconferences from within the enterprise,
or from outside? For example, if there are many internal Scopia® XT Desktop Clients, consider
placing a dedicated Conference Server in the enterprise.

• What is your network's security policy?

Depending on where you deploy the Scopia® XT Desktop server and other video network
devices, you may need to open different ports on the firewall.

• How much internal and external bandwidth is required, based on the number of simultaneous
users joining videoconferences? Consider also whether most users will be joining in standard
or high definition.

See the following sections for details on the different deployment options and how to plan your
bandwidth:

Planning the Topology of Avaya Scopia® XT Series with Scopia® XT Desktop

Avaya Scopia® XT Series SMB Edition enables you to locally host videoconferences using its built­in MCU, and extends your videoconferences to participants joining from a computer (with Scopia
XT Desktop Client) or a mobile device (using Scopia® Mobile).

For example, when you start a videoconference with the XT Series hosting the call, you can add
other participants by asking them to connect via a web link to the Scopia® XT Desktop server, which
would automatically install and launch Scopia® XT Desktop Client on their computers, or Scopia
Mobile on their mobile devices.

The main features of the Avaya Scopia® XT Series SMB Edition include:

• Remote users can easily connect to a meeting hosted by the built-in MCU on the XT Series, by
connecting via the Scopia® XT Desktop server.

®

®

The deployment has very few components. You do not need additional hardware like an
external MCU, Avaya Scopia® PathFinder for firewall traversal, or Avaya Scopia® ECS
Gatekeeper for routing calls.

Planning the Topology of Avaya Scopia® XT Series with Scopia® XT Desktop

• The included Scopia® XT Desktop provides built-in NAT and firewall traversal functionality,
enabling secure remote connections from Scopia® Mobile and Scopia® XT Desktop Clients.

You can enable this functionality via the XT Series license.

The Avaya Scopia® XT Series SMB Edition includes the following options:

• Full SMB4 - Basic MCU level with up to four participants: one local and three remote endpoints
or PC clients.

• Full SMB9 - Advanced MCU level, with one local participant and up to eight remote endpoints
or PC clients.

There is no local endpoint if you deploy the XT Series as a video server.

Important:

The Scopia® XT Executive and Avaya Scopia® XT4300 can host up to four participants.

Figure 4: Avaya Scopia® XT Series SMB Edition Deployment on page 11 shows a typical topology

for the Avaya Scopia® XT Series SMB Edition solution. For more information, see the Solution
Guide for Scopia® Solution.

Deploying Scopia® XT Desktop server with Dual-NIC

Scopia® XT Desktop server can be installed on servers with multiple Network Interface
Cards (NICs). Depending on the deployment and network configuration, you may want to control
which NIC is used for various server communications.

Important:

The minimum requirement is to use a 100 Mbit NIC. It is recommended that you use a Gigabyte
NIC for better performance. Bandwidth shown is for Standard Definition (384 kbps) or High
Definition (1024 kbps).

For example, in secure multiple NIC deployments you can use a NIC configured behind the firewall
to communicate with the Avaya Scopia® XT Series, while using another NIC for Scopia® XT
Desktop Client connections (Figure 5: Scopia® XT Desktop with a dual-NIC deployment on
page 12). In this case, configure the Scopia® XT Desktop IP address to represent the NIC behind
the firewall. For the Scopia® XT Desktop public address, use a DNS name which resolves to the
NIC outside the firewall, and is accessible both inside and outside the enterprise.

For more information and to configure the public address, see

Defining Scopia® XT Desktop server

Public Address and Other Client Connection Settings on page 31.

Figure 5: Scopia® XT Desktop with a dual-NIC deployment

Scopia® XT Desktop Clients can connect to the Scopia® XT Desktop server either by an IP address
or a DNS name. In many deployments the Scopia® XT Desktop server IP address is not accessible
to clients outside the enterprise due to NAT or firewall restrictions. Therefore, Scopia® XT Desktop
server has a public address, which must be a DNS name resolving to the correct Scopia® XT
Desktop server IP address both inside and outside the corporate network.

Estimating and Planning your Bandwidth Requirements

We recommend estimating Scopia® XT Desktop's impact on bandwidth to determine if your current
infrastructure needs updating. Planning bandwidth may help reduce costs in your organization.

This section explains how to estimate the bandwidth for external Scopia® XT Desktop users
connecting to your network.

Important:

You do not need to estimate bandwidth required by users who connect from within the internal
network, because, typically, internal bandwidth is sufficient for videoconferencing.

You can allocate the bandwidth depending on the needs of your organization.

Since the Scopia® XT Desktop coordinates videoconferences between Scopia® XT Desktop Clients/
Scopia® Mobile devices and the MCU, you must plan bandwidth required by the Scopia® XT
Desktop server and by the MCU jointly. Consider the MCU resources when planning your Scopia
XT Desktop bandwidth.

®

To assess the overall bandwidth for the videoconferencing solution including other types of
endpoints, refer to the Avaya Scopia® Solution Guide.

Calculating the Bandwidth Used by Avaya Scopia® XT Desktop Participants

About this task

Videoconference participants consume most of the bandwidth in your Avaya Scopia® XT Desktop
deployment, because they both upload and download live media.

This section explains how to estimate the bandwidth for external Scopia® XT Desktop users
connecting to your network.

Important:

You do not need to estimate bandwidth required by users who connect from within the internal
network, because, typically, internal bandwidth is sufficient for videoconferencing.

The amount of bandwidth consumed by participants mainly depends on the chosen topology and
the maximum bandwidth you allow per participant. You configure the maximum bandwidth per

Planning your Avaya Scopia® XT Desktop Deployment

participant in the Scopia® XT Desktop server which is the maximum possible bandwidth for any
participant connecting to this server.

You calculate the maximum bandwidth used by Avaya Scopia® XT Desktop participants in the
following steps:

Procedure

1. Estimate the number of Avaya Scopia® XT Desktop participants connecting externally.

2. Decide on the maximum bandwidth per Scopia® XT Desktop Client (measured as its bitrate).

3. Calculate the peak bandwidth according to the following formula:

Peak bandwidth = peak usage x maximum bandwidth per participant

In our example of the Avaya Scopia® XT Desktop deployment, where the peak usage is 10
and the chosen maximum bandwidth is 768 Kbps, the peak bandwidth equals 7680 kbps.
This is the rough estimation of the bandwidth required for videoconference participants.

4. Add margins to make sure that even in poor network conditions video quality does not drop
below the standard you decided on.

Important:

An average margin is 20% of your fine-tuned estimation.
