1.4 Additional Concepts and Terms The sections below include additional concepts and terms used in the Sheer
DNA Manage application and throughout this guide.
AVM
The Sheer DNA Units are divided into AVMs (Autonomous Virtual
Machines). These AVMs are Java processes that provide the necessary
distribution support platform for executing and monitoring multiple VNEs.
AVMs and VNEs should reside on a Sheer DNA Unit (as a common
configuration) but they can also reside on a Sheer DNA Gateway.
There are some types of AVMs that run on the server which do not run
VNEs. These AVMs have reserved ID numbers, namely, AVM 0-100 and these
cannot be used. In addition, there are other reserved AVM ID numbers. The
following AVMs have special roles assigned to them, namely:
• AVM 0 (the switch AVM)
• AVM 11 (the Gateway)
• AVM 66 (the workflows AVM)
• AVM 99 (the management AVM)
• AVM 100 (the trap management AVM)
Device/Network Element
A network component existing in the network, for example, the devices
displayed in Sheer DNA and in Sheer NetworkVision.
Element Management
The base configuration for the creation of the managed element. Sheer DNA
Manage enables the user to create VNEs, for example, by entering the IP
address, SNMP and polling rate information and so on. This is called
Element Management.
