) is active – see paragraph 6.1).Unlike Time View and Message View which are based on a straight forward message analysis, building the Network View requires some more complicated processing:
34.12.1 Association
Association of short MAC addresses to long MAC addresses by identifying coordinator association messages. This allows associating a message with PAN + short address with the same device as a message with the relevant long MAC address.
34.12.2 Indirect device identification
Besides of devices received by the analyzer directly, the analyzer deduces the existence of other devices by identifying their presence from coordinator commands, beacon assignments, neighbor lists, report messages and route messages.
34.12.3 Device information import/export
Some of the data collected by the analyzer when building the Network View may be used later when performing further captures from the same network (device name user definitions, devices' positions on a floor plan, etc.). The devices information collected during a specific capture session and any additional information that the user decides to include in it, can be exported to a Device File (.ANV), and then used by a different capture session through the Workspace settings form. In this way, association data captured in one (previous) session can be used to associate messages of another capture data file.
34.12.4 Network View drawing
Drawing of the Network View is accomplished by a special position optimization algorithm included in the Perytons™ Protocol Analyzer. This algorithm aims to position neighbor devices near to each other and to decrease the number of overlapping connections.
The optimization runs continuously
during data capture or whenever a pre-captured data file is opened (unless the
'Freeze' mode () is active – see paragraph 6.1).
Note: When handling large
networks (networks having thousands of devices), the optimization of the
devices' position may take some time (10’s sec) when opening the pre-captured
data file. The user may skip this calculation step by pressing the 
sign
that appears near the progress bar at the bottom left hand side of the main
window. Even if the Device position optimization process has been stopped, all
the devices and their related information (connections, routes, etc.) will be
shown in the Network View window, but their position within the view may not be
optimized.
