Multiple Network Setup - Comrex ACCESS MultiRack Product Manual

As shown in Figure 38, BRIC Normal connections happen over the CrossLock VPN Layer. The CrossLock connection
between the Comrex hardware happens over a single port (9001), but the BRIC Normal connections take place
virtually on their usual legacy ports within that VPN. The system will show these virtual connections happening
on ports 9000, 9002 and 9003 (these are the BRIC Normal ports)—however, the only actual connection between
hardware is happening on 9001. For this reason, if you only intend to make CrossLock connections to MultiRack,
only UDP port 9001 needs to be open or forwarded.
It's important to note that the single port—UDP9001—is used for all CrossLock connections, regardless of how
many instances are using CrossLock simultaneously.
FIgure 38 crosslock Vpn
One limitation of CrossLock is that each codec that joins the CrossLock VPN must be familiar with the others. This
process takes place automatically when Switchboard is used. As detailed in section IX, connections that don't use
Switchboard need special configuration.

multIple network setup

In the case of more than one network attached to a MultiRack (e.g. two Ethernet cables, a Wif-fi or 4G adapter,
etc.), all networks are added to the CrossLock VPN and used for media transfer (unless specifically disabled for
CrossLock use). The "performance" tab on the web interface will show the ratio of data being applied to networks
on both the send and receive direction.
By default, data is apportioned between the network is in a "Bonding" mode. This means the entire data channel is
broken into pieces and apportioned among the networks. This mode is best for networks of unknown quality. If one
network becomes constrained, data will be allotted dynamically among the others. Bonding mode is very effective
even when one network drops entirely, often providing glitch-free audio as data is switched over.
Alternately, CrossLock can be configured for "Redundant" mode. This is best for networks of known good quality. All
data is reproduced over every available network, and only the first packet to arrive at the decoder is used.
