Tracking Instances of a String

Hi everyone.

I'm working on a sketch to build a set of 3D objects based off information gathered from tcpdump. I've setup a class called 'packet' that contains the source, destination, and protocol of each packet I've captured. All of the packet objects are stored in an array.

I would like to have the sketch walk through this array and group packet objects that have matching source strings together with hopes of drawing cubes for each source in a similar x, y, z space.

My code is a mess, I'm a bit frustrated, and I feel like I need a fresh perspective on the problem.

Here's the code with different attempts commented out:

CSV File "csv":
2. "1","0.000000","10.73.30.223","255.255.255.255","DB-LSP-DISC","Dropbox LAN sync Discovery Protocol"
3. "2","0.000354","10.73.30.223","10.73.31.255","DB-LSP-DISC","Dropbox LAN sync Discovery Protocol"
4. "3","0.072580","184.50.45.206","10.73.27.148","TCP","[TCP segment of a reassembled PDU]"
5. "4","0.072807","184.50.45.206","10.73.27.148","TCP","[TCP segment of a reassembled PDU]"
6. "5","0.073097","184.50.45.206","10.73.27.148","TCP","[TCP segment of a reassembled PDU]"
