Understanding network system
concepts
Make sure you understand the following system concepts before planning or
implementing an Aurora Browse/MediaFrame system.
• “Control network description”
• “Streaming/FTP network description”
• “Media (iSCSI) network description”
• “Networking tips”
• “About hosts files”
• “Host table tips”
Control network description
The control network is for communication between devices and components. It does
not have real-time media traffic or streaming/FTP media traffic. The control network
must be on a different subnet than the streaming/FTP network and the Media (iSCSI)
network. Static IP addresses with name resolution via host files are recommended for
the control network.
The control network applies to all MediaFrame servers, Aurora Servers, Encoders,
and any device managed by the MediaFrame system. Aurora Browse and Aurora Edit
LD clients can also be on the control network but typically they are configured to only
run on the corporate LAN.
Streaming/FTP network description
The streaming/FTP network is for media transfers and FTP traffic. It must be on a
different subnet than the control network and the Media (iSCSI) network. Static IP
addresses with name resolution via host files are recommended for the streaming/FTP
network. Host names of network adapters that are dedicated to the streaming/FTP
network must be aliased in the hosts file with the _he0 suffix. This directs the
streaming traffic to the correct port.
The streaming/FTP network applies to MediaFrame servers, MDI servers, K2
BaseCamp Express, SmartBin Encoders, and FTP servers. It also applies to Aurora
Proxy Encoders using a GXF FTP server that is not hosted on the Encoder. This is the
primary network for moving media between storage systems.
Media (iSCSI) network description
The media network is exclusively for real-time iSCSI traffic on a K2 SAN. It must be
on a different subnet than the control network and the streaming/FTP network.
Furthermore, its traffic is kept physically separate from that of other networks. This
separation is provided by dedicated ports, cables, and by a dedicated VLAN on the
