Version 8.2.1 About Scopia XT Desktop Server for IP Office | 5

Figure 2: Components of the Scopia XT Desktop Server

•Scopia XT Desktop Conference Server

At the center of Scopia XT Desktop Server, the conference server creates conferences with Scopia

XT Desktop Clients and Scopia Mobile devices, relaying media to the MCU to enable transparent

connectivity with H.323 and SIP endpoints.

•Scopia XT Desktop Application Server (Tomcat)

The underlying Scopia XT Desktop web server and application server is implemented by Tomcat. It

serves as the update server, the Scopia Content Slider server and the Scopia XT Desktop web

portal.

•Scopia Content Slider server

Part of the Tomcat Application Server, it stores the data already presented in the videoconference

and makes it available for participants to view during the meeting.

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.

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

Scopia XT Desktop Server Security Specifications

Scopia XT Desktop Server has extensive support for security, both standard encryption with certificates

and a proprietary secure protocol between the client and server:

•HTTPS protocol between Scopia XT Desktop Client and Scopia XT Desktop Server.

•SRTP encryption between Scopia XT Desktop Client/Scopia Mobile and Scopia XT Desktop

Server

•TLS encryption between Scopia XT Desktop Server and Scopia Management

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

–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.
