Chapter 2 | Planning your Scopia XT
Desktop Server Deployment
When planning your Scopia XT Desktop Server 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.

Planning the Topology of Scopia XT Server for IP Office
with Scopia XT Desktop
Scopia XT Server for IP Office enables you to locally host videoconferences using its built-in 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 Server 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.
If you do not register to IP Office, you cannot host videoconferences or use the full functionality of the
system.
The main features of the Scopia XT Server for IP Office include:
• Remote users can easily connect to a meeting hosted by the built-in MCU on the XT Server, by
connecting via the Scopia XT Desktop Server.
The deployment has very few components. You do not need additional hardware like an external
MCU, Scopia PathFinder for firewall traversal, or Scopia ECS Gatekeeper for routing calls.
• 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.
The Scopia XT Server for IP Office includes the following:
• Full SMB9 - Advanced MCU level, with up to 8 participants:
– Eight endpoints
Or
– Seven mixed endpoints and PC clients
Figure 3: Scopia XT Server for IP Office Deployment on page 10 shows a typical topology for the
Scopia XT Server for IP Office solution. For more information, see the Solution Guide for Scopia
Solution.

Figure 3: Scopia XT Server for IP Office Deployment
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 Scopia XT Server for IP Office, while using another NIC for Scopia XT Desktop
Client connections (Figure 4: Scopia XT Desktop Server with a dual-NIC deployment on page 11). 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 28.
Deployment Guide for Scopia XT Desktop Server for IP Office
Version 8.2.1
Planning your Scopia XT Desktop Server Deployment | 10
Figure 4: Scopia XT Desktop Server 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.
Planning your Bandwidth Requirements
The Scopia Solution supports a number of technologies designed to minimize the bandwidth used in
videoconferences. For more information on the bandwidth-saving features of Scopia Solution, see
Scopia Solution Guide. Even so, there are policy decisions you can make to reduce bandwidth further by
deciding on the location of video network components and setting bandwidth management policies in
your organization. You can estimate the total bandwidth required for Scopia XT Desktop, which includes:
• Bandwidth consumed by videoconference participants connecting to the Scopia XT Desktop
Server (Scopia XT Desktop Clients and Scopia Mobile devices)
Use your Scopia XT Desktop bandwidth estimation to do the following:
• Calculate your bandwidth costs, for both external and internal bandwidth (see Calculating the
Bandwidth Used by Scopia XT Desktop Participants on page 11).
For example, to reduce bandwidth, you may decide that all calls going outside your organization
are limited to standard definition (SD), or that all calls are SD by default.

Calculating the Bandwidth Used by Scopia XT Desktop
Participants
This section describes how to calculate the bandwidth required for videoconferences with Scopia XT
Desktop participants (both Scopia XT Desktop Clients and Scopia Mobile devices).

Calculating Scopia XT Desktop Bandwidth Usage
This topic describes how to calculate the bandwidth required for adding Scopia XT Desktop Clients and
Scopia Mobile devices to a videoconference hosted on the Scopia XT Server for IP Office using it's builtin MCU (see Figure 5: Upload and download bandwidths for Scopia XT Desktop on page 12)
Figure 5: Upload and download bandwidths for Scopia XT Desktop
The bandwidth used for each Scopia XT Desktop Client participant is defined in the server settings (see
Figure 6: Setting maximum bandwidth in Scopia XT Desktop Server on page 13).
Deployment Guide for Scopia XT Desktop Server for IP Office
Version 8.2.1
Planning your Scopia XT Desktop Server Deployment | 12
Figure 6: Setting maximum bandwidth in Scopia XT Desktop Server
The formula for calculating external bandwidth is as follows:
Total upload bandwidth = upload bandwidth per participant × num of internet participants
Total download bandwidth = download bandwidth per participant × num of internet participants
For example, if the defined call rate is 384 kbps, each participant uses 384 kbps for uploading and 384
kbps for downloading. So if 5 Scopia XT Desktop participants connect to a videoconference from the
external internet at 384 kbps, the bandwidth for these participants is 384 x 5 = 1920 kbps for upload and
1920 kbps for download.
Ports to Open on Scopia XT Desktop
The Scopia XT Desktop Server is typically located in the DMZ (see Figure 7: Locating the Scopia XT
Desktop Server in the DMZ on page 14) and is therefore connected to both the enterprise and the
public networks. Scopia XT Desktop Clients can be located in the internal enterprise network, in the
public network, or in a partner network.
