Page 5: Star
Network Topologies Star For systems needing more scalability than that offered by a single logical switch, multiple logical switches can be each connected to a single switch for intercommunication. In this topology, the central switch is referred to as a “core”... -
Page 6: Fat Tree
Network Topologies Fat Tree Very large network systems often fall into the category of a fat tree topology. Here, access switches are connected to a distribution switch in a manner like a star network. Multiple distribution switches are in turn connected to a core switch. -
Page 7: Layer Terminology
Network Topologies Layer Terminology Users often refer to switches as a “layer 2 switch” or a “layer 3 switch”, often insisting that a “layer 3 switch” is necessary for a multicast network to function properly. This statement isn’t always true, but to understand why, the terms “layer 2 switch”... -
Page 8: Per Stream Bandwidth Utilization
Per Stream Bandwidth Utilization To effectively plan a network, it is necessary to understand how bandwidth on that network will be utilized. By first understanding how much bandwidth each stream on each switch will utilize, it becomes easy to see how bandwidth across the system will be utilized. -
Page 9: Video
For OmniStream R-Type, the total bandwidth utilization for a video stream is 900 Mbps. FEC (OmniStream Pro Only) Forward Error Correction (FEC) has a bandwidth penalty associated with its use. Atlona’s implementation of FEC is per SMPTE 2022-5:2013 and does not require any extra network consideration beyond the bandwidth penalty described here. -
Page 10: Fec (Omnistream Pro Only)
OmniStream 232 Dante audio bandwidth utilization can be assumed to be 1.5 Mbps per channel. FEC (OmniStream Pro Only) Atlona’s implementation of FEC is per SMPTE 2022-5:2013 and does not require any extra network consideration beyond the bandwidth penalty described here. -
Page 11: Trunk Bandwidth Utilization
Trunk Bandwidth Utilization In star or fat tree topologies, multiple switches are interconnected with trunk links. Trunk links are interconnections between switches which enable higher bandwidth connections between switches. To understand how link bandwidth will be used, you must first understand how the traffic will flow. It is recommended that trunk link bandwidth utilization not exceed 80% of trunk link capacity. - Page 12 Trunk Bandwidth Utilization Figure 2 - Unicast mode: encoder and decoder using different switches. “Core” Switch “Access” Switch “Access” Switch AT-OMNI-122 (Decoder) Legend AT -O Data flow AT-OMNI-112 (Encoder) Unused connection For multicast streams, the network will do two things: •...

Page 15: Trunk Downlink
Trunk Bandwidth Utilization Trunk Downlink The trunk downlink bandwidth utilization is the sum of all traffic flowing to the switch in question to the other switch connected to the link. When computing trunk downlink bandwidth utilization, it is best practice to assume worst-case by accounting for the maximum amount of multicast traffic possible, coming from another switch. -
Page 16: Igmp / Multicast Routing Requirements
IGMP / Multicast Routing Requirements For networks using unicast only (point to single point), there is no special configuration needed for IGMP/multicast routing. For networks using multicast or a combination of unicast and multicast, IGMP/multicast routing must be properly configured to avoid traffic flooding ports and causing unnecessary outages. Note that based on unit configuration, multiple unicasts/multicasts can be generated from single HDMI sources. -
Page 17: Handling Of Unregistered Multicasts
• 224.0.0.232 Multicast DNS (mDNS) The Atlona Management System (AMS) uses mDNS for automatic device discovery. By default, mDNS discovery does not function beyond VLAN/subnet boundaries. Switchport Configuration On switches that support it, any ports connected to OmniStream devices should have the below options configured to enable the port to establish a link quickly upon device connection. -

OmniStream device. Other switches (e.g., Cisco SG300) do not try to intelligently allocate power and thus do not require this. The Atlona Management System (AMS) is used for centralized management of OmniStream devices. All UDP ports between AMS and OmniStream must be open and available, as AMS uses WebSockets to communicate with OmniStream. - Page 19 • 408.962.0515 • 877.536.3976 © 2017 Atlona Inc.
