APPENDIX C - Redundant servers: Setting up and swapping out
This appendix contains two main sections related to the creation and repair of A.I.M. 
server installations that employ redundancy. 
• Setting up A.I.M. server redundancy - below 
• Swapping out an A.I.M. server - on next page
When upgrading from a 3.1 redundant system after upgrading the primary A.I.M. server 
and then the associated devices to 3.3, it is important to remember to...

Swapping out an A.I.M. server
Once ALIF devices have been configured to run with an A.I.M. server, their default IP 
addresses are automatically changed as part of the installation process. In this state the 
ALIF devices become undetectable to any new A.I.M. server that does not have access to 
the database of devices. Therefore, if an existing A.I.M. server needs to be replaced within 
an installation, follow one of the basic procedures...

APPENDIX D - Glossary
Internet Group Management Protocol
Where an ALIF transmitter is required to stream video to 
two or more receivers, multicasting is the method used. 
Multicasting involves the delivery of identical data to 
multiple receivers simultaneously without the need to 
maintain individual links. When multicast data packets enter 
a subnet, the natural reaction of the switches that bind 
all the hosts together within the...

Spanning Tree Protocol (STP)
In order to build a robust network, it is necessary 
to include certain levels of redundancy within the 
interconnections between switches. This will help to 
ensure that a failure of one link does not lead to a 
complete failure of the whole network.
The danger of multiple links is that data packets, especially 
multicast packets, become involved in continual loops as 
neighboring switches use the duplicated...

Forwarding modes
In essence, the job of a layer 2 switch is to transfer as 
fast as possible, data packets arriving at one port out to 
another port as determined by the destination address. 
This is known as data forwarding and most switches offer 
a choice of methods to achieve this. Choosing the most 
appropriate forwarding method can often have a sizeable 
impact on the overall speed of switching:
• Store and forward is the original...

APPENDIX E - A.I.M. API
The A.I.M. API provides access for external applications to key routines used within the 
A.I.M. server. This appendix provides a reference to the available methods. 
API version: 3
Changelog
• v3 (A.I.M. v3.2) - added create_preset, delete_preset.
• v2 (A.I.M. v2.3) - added get_devices, get_channels, connect_channel, disconnect_
channel. Updated version compatibility information.
• v1 (A.I.M. v1.3) - added login,...

logout
This method was last updated in API version 1, and is compatible with API requests from 
version 1 onwards.
The authentication token provided by the Login function can be used until the logout 
function is called.
Input parameters:
- token
- v (the A.I.M. API version this request is designed for)
Output values:
- timestamp - the current server time
- success - 0 = fail, 1 = success
Examples
