NETWORK-MODEL REVIEW WORKSHEET

Article: https://yenra.com/wiki/SVN_software_virtual_network_battlefield_communication_simulation/

Purpose: Describe the assumptions, measurements, and validation behind a
network simulation or emulation result. Edit this text file for a study.
This worksheet is a learning/review aid, not an operational test procedure.

1. STUDY BOUNDARY
Question being answered:
Application behavior of interest:
Tool, release, libraries, and configuration:
Simulated elements / real elements / connecting interfaces:
Topology, traffic, and environmental assumptions:
Run duration and observation-window definition:
Random seeds and number of repetitions, where relevant:
Clock reference and evidence that timing was maintained:

2. METRIC DEFINITION (repeat for every reported metric)
Unit counted (packet, unique message, file, transaction, etc.):
Start/end points of measurement:
Deadline and its justification:
Numerator / denominator / units:
Measurement method:
Observed results and variation:

3. SYNTHETIC EXERCISE — INVENTED VALUES
Sent: 1,000 unique application messages.
Exercise deadline: 100 milliseconds one-way, using a suitable common clock.
Arrived within deadline: 960.
Arrived late, within observation window: 30.
Missing at observation-window close: 10.
Assume each message is counted exactly once, with no duplicate arrivals.

Delivered within window = (960 + 30) / 1,000 = 99%.
Timely delivery = 960 / 1,000 = 96%.
Late delivery = 30 / 1,000 = 3% of messages sent.
Missing share = 10 / 1,000 = 1%.
Check: 960 + 30 + 10 = 1,000.

The 100 ms deadline is an exercise assumption, not a military requirement.
These values are not results from EXata, a radio, or a deployed network.
A delivery percentage alone does not disclose timely delivery.

4. VALIDATION AND INTERPRETATION
Reference measurement or independently known case:
Properties compared, conditions, and allowed disagreement:
Results of comparison:
Assumptions varied and effect on results:
Host/timing constraints or implementation limits:
What the evidence supports:
What remains unvalidated:
Evidence needed before using the result for a different scenario:
