+## Homework 3: Example Simulation Recording OpenDIS Network Streams
+
+### Assignment
+
+* Adapt the functionality for [OpenDIS ExampleSimulationProgram](../../../../examples/src/OpenDis7Examples/ExampleSimulationProgram.java), modifying provided code
+* Result streams are recorded/saved/replayed using Wireshark or X3D-Edit.
+
+This assignment presents a Problem Prototyping opportunity.
+While some minimal functionality is expected, the general outline of
+a networking problem and proposed solution holds great interest.
+Think of it as a warmup preparation for your final project.
+
+This is also a freeplay opportunity.
+ You have the option to pick one or more of the provided course example programs
+and adapt the source to demonstrate a new client-server handshake protocol of interest.
+
+Be sure to provide a rationale that justifies why the networking choices you made
+(TCP/UDP, unicast/multicast, etc.) are the best for the problem you are addressing.
+
+Refer to [homework2 README](../homework2/README.md) and [assignments README](../../../README.md)
+for further details on what specific deliverables are expected in each homework assignment.
+
+Team efforts are encouraged, though if you choose a team approach be sure to justify why.
+This is a good warmup prior to final projects. Have fun with Java networking!
+
+### Prior Assignment, August 2019
+
+In 2019, students worked together on a single project to check wireless multicast connectivity recently deployed on NPS campus.
+
+See their experimental results in the [NPS Multicast Connectivity Report](../../MV3500Cohort2019JulySeptember/homework3).
