tutes additional processing power, in effect

increasing overall system performance.

Minimal Network Trafﬁc: Impact on net-

work trafﬁc is minimal no matter how many

IP Link Ethernet control interfaces are used

on the network. Processing occurs inside the

IP Link interfaces and control commands are

sent locally to the connected A/V devices.

IP Link interfaces only speak when spoken

to. As long as control Web pages are devel-

oped using the best practices outlined in the

users manuals, network trafﬁc generated by

them will be very light.

Scalability: As an organization grows,

it's critical that the A/V monitoring system

keep up with the addition of new presen-

tation rooms and equipment. Centralized

processors are often limited in the number

of control ports that can be added, and in-

stead, they have to be replaced with larger

and more expensive processors as systems

grow. IP Link Ethernet control interfaces are

available in a wide array of device conﬁgu-

rations, offering serial ports, Flex I/O ports,

and IR capabilities.

The core technology of IP Link makes it ide-

al for implementing A/V system management

over the most widely available transport me-

dium today, the corporate IP network. In my

next article, I'll describe how Global Viewer

software leverages IP Link's technology for

powerful Web-based asset management and

remote monitoring.

the Web-based asset management and re-

mote monitoring application developed for

use with IP Link Ethernet network interfac-

es. The Global Viewer is provided for free

and there are no licensing fees and no per-

seat charges, no matter how many users.

The beneﬁts of using IP Link technology

with Global Viewer for monitoring and

control of A/V systems are numerous:

•

Device setup and conﬁguration of au-

tomated tasks is simple and doesn't require

any specialized programming skills.

•

Remote, browser-based A/V system

monitoring and management from mul-

tiple control points (e.g., computer, PDA,

or cell phone) from virtually anywhere in

the world.

•

Instant e-mail notiﬁcation of device

tampering, pre-scheduled events, and

maintenance reminders.

•

Reduced device ownership costs and

more efﬁcient use of labor resources.

Global Viewer provides an easy-to-

operate method for monitoring and

controlling an organization's entire A/V

system, including projectors, cameras,

audio/video playback equipment, lighting

controllers, screen controllers, and more.

Delivering real-time status information

through a single intuitive interface, the

Global Viewer enables IT and A/V system

administrators to be more productive, and

greatly simpliﬁes the management of het-

erogeneous A/V system environments.

The operating system supports the open

source/open architecture philosophy of

Web-based languages like HTML, XML, and

JavaScript. This open architecture makes

A/V systems accessible via a wide array of

control points, including laptops, desktops,

handhelds, and even Web-enabled cell

phones. All that's needed is a Web browser

and access to the network.

What's So Good About a

Distributed Architecture?

The distinct advantages of IP Link's distrib-

uted architecture include fault tolerance, a

high level of performance, minimal impact on

network trafﬁc, and system scalability.

Fault-Tolerance: Unlike a system that em-

ploys a centralized processor with many con-

trol ports, IP Link systems use many distributed

processors with control ports on each one. The

resilience in the IP Link design is essential in

reducing the effect a partial network failure

might have on the service and support of the

managed resources. Part of the network may

fail, but by design, the rest of the manage-

ment system will not be affected.

High Performance: Each IP Link interface

operates as an independent control pro-

cessor, so commands to and from multiple

IP Link interfaces can be sent and received

simultaneously. Our distributed architec-

ture and high speed processors combine to

eliminate bottlenecks. In fact, each additional

IP Link interface added to the system consti-
