So, an update on some of the things I tried to resolve my networking
problem (Unable to stream two cameras simultaneously).
I ended up purchasing a tp-link 5 port switch (tl-sg105). I selected this
based on your comment regarding the buffers on the switch. This switch has
1MB Buffer Memory. After incorporating the switch, I still didn't get any
noticeable improvement with the number of dropped frames I was experiencing.
Next, I also opened two instances of Point Grey's Flycap software (the
manufactures in-house software package to view images and modify camera
settings) which removed aravis from the setup. Image acquisition was still
In the end, I switched the frame size to 6000 and increased the delay. The
camera delays were offset about 3000. Camera 1 was set to 3000 and Camera
2 set to 6000. This resolved the problem and I was able to stream both
cameras simultaneously. This was tested on the both switches successfully:
tp-link and netgear pro safe (GS105). This seems counterintuitive to
everything I have read about setting the packet size to largest possible
setting your is network cable of, but apparently not in this case!
Hope this helps someone and I appreciate the help and comments you sent.

Both cameras are connected via a Netgear Giabit Switch (Prosafe GS105)
From the documentation:
* Queue Buffer Memory: 12 kbytes per port
If your cameras are able to emit their data using more than 50% of a
gigabit link, these queue buffers will probably overflow.
