Chapter 1: StreamNet Networking
STREAMNET NETWORKING GUIDE
StreamNet is a third-generation networked AV media and control technology that provides the
highest quality audio and video signaling and controls with unmatched scalability when compared
to other networking and legacy AV distribution technologies. StreamNet was designed to work over
Internet Protocol, and hence can be deployed over many networking topologies and infrastructures
such as fiber, UTP, power line or even wireless with the proper QoS. StreamNet system designs are
flexible and can co-exist with other networking traffic and can be used in deployments with one or
more routers, or any number of VLAN’s where necessary.
StreamNet allows your network to be shared between audio video distribution, controls and traditional PC applications. No need for multiple data infrastructures or expensive proprietary infrastructure requirements. Most commercial and enterprise buildings in the United States are already
equipped with the necessary networking hardware to deploy a StreamNet solution.
This guide was intended to provide the basic requirements needed to ensure a reliable Quality of
Service (QoS) for any StreamNet deployment. The vast majority of all StreamNet systems in place
today utilize standard commodity gigabit Ethernet or Fast Ethernet as the infrastructure and most
are provisioned on a single LAN.
StreamNet has no limit to the total number of sources, displays or control points connected to the
network. The network infrastructure needs to be designed and configured appropriately to accommodate your needs and specification.
StreamNet is synchronized to within 1 ms anywhere on the network. This time precision is assured
by a high-performance hardware-assisted StreamNet time protocol. All StreamNet audio processing is sonically transparent and the high quality 24-bit DAC and 24-bit ADC used throughout encoding and decoding are designed to ensure high quality audio and preserves dynamic range.
St r e a m Ne t v S . ot h e r av Ne t w o r k S
StreamNet technology utilizes 100% Internet Protocol that allow real time AV distribution and control. A good way to examine other network solutions is to reference the OSI model for understanding how networks are organized. You can compare these solutions based on where they are used
within the OSI network chart.

Chapter 1: StreamNet Networking 2
Physical Layer (Layer 1) - Communication technologies operate at the basic Physical Layer.
These kinds of technologies use unsophisticated protocols and basic communication techniques.
This kind of technology is most often used in point-to-point applications. Some solutions use proprietary built infrastructure and routing equipment. Examples of Layer 1 solutions would be Rocknet™, A-Net™ and EtherSound™.
Data Link Layer (Layer 2) - Technologies based on the Data Link Layer allow for more robust
communications. Ethernet is based on Layer 2 and many AV networking solutions use this infrastructure however they cannot scale beyond it. This does allow coexistence of multiple services on
the same physical connection such as audio with PC traffic.
CobraNet™ has not always been a Layer 2 solution, but has evolved to this status today. While it
pales in comparison to Internet Protocol solutions in terms of Audio and Video distribution and controls and number of channels is limited, it has had arguably the most success of any of the legacy
audio network technologies.
Network Layer (Layer 3) - Layer 3 networking is the same technology as the Internet. Dante™
and StreamNet are two examples of IP based AV technologies.
StreamNet incorporates its own discovery of network devices, and fully incorporates IGMP to manage unnecessary networking traffic. Audio video and controls are all packetized and sent over the
network using standard IEEE 802.3 packets for most supported StreamNet stream types with the
exception of MotionXT. MotionXT is a special StreamNet stream type that utilizes jumbo packets.
Other StreamNet stream types are Stereo Audio 44.1k, Stereo Audio 48k, Mono Audio 48k, Highbit-rate Audio, S/PDIF, Control, and Uncompressed HDAV.
The following information can be used to set up your switch infrastructure for reliable AV distribution.
STREAMNET NETWORKING CONCEPTS
There are several different types of Network Topologies that can be used to configure a Switch Network. Ring, Mesh, Star, Line are examples of Switch Topologies available. Of these, Star Topology is
the StreamNet recommended topology. This is due to the Network and Bandwidth Load Balancing
that needs to be considered when designing a project.
Star Topology consists of several switches connected to a central, higher-capacity switch - see
example below.

A Router is a Network device that connects two or more Networks together to allow data traffic to
be routed between the separate networks. Typically in a Residential scenario this is used to connect
the Local Area Network (LAN) to the Wide Area Network (WAN or Internet).
When choosing a Router to be used with the StreamNet products, it is recommended the use of
a Router that allows disabling the IGMP feature set or does not elect to subscribe to the Internet
Group management Protocol (IGMP or Multicast) as well as turning off Broadcast filters and Storm
Controls.

Default Gateway is a node on a network that serves as an access point to other networks. The Default Gateway and Subnet Mask are set automatically when using the DHCP option in the StreamNet Dealer Setup software. If using Static IP Addressing with the StreamNet devices the settings for
the Default Gateway can be entered in the System Settings section of the StreamNet Dealer Setup
software. (Default Gateway settings can be requested from the Network Technician or found in the
Routers LAN Configuration section of the setup software).
IP ad d r e S S I N g
Defining and Managing IP Addresses and Subnets
Managing the IP Address schemes within a network are handled by allocating, recycling and documenting IP addresses and subnets in a network. IP addressing defines Subnet sizes, Subnet assignments, Device Assignments and Dynamic Host Address Assignments within a Subnet range.
This helps reduce the possibility of the Subnet Overlapping or Duplicate IP Addresses within a
Subnet, inefficient use of IP Addresses and unnecessary complexity. Some uses of IP Address
Management are DHCP Ranges, Auto IP Ranges and Static IP Addresses.
