NEWS & UPDATES 》 TOFFEE-Mocha WAN Emulation software development - Update: 18-June-2016

In the previous update (17-Jun-2016) I discussed about the upcoming new Random Packet drop feature along with other completed features.

Now I completed the entire TOFFEE-Mocha Random packet drop feature. I completed all the kernel components and the UI support of the same. And to make GUI settings more organized I split the earlier Basic-Settings page into two separate pages namely: Packet Drop and Packet Delay. So this way it is simple to understand settings according to their functionality.

As you can see below the Random Packet drop feature have two options to set. The first option is to enable or disable the feature. The second option is to set its probability. If the value chosen is 1, then it has the probability of a random number between 1-10. So there are more chances that the packet may get drop. And as the way you increase this value to 2 and 3 and so on. The probability of packets randomly being dropped will reduce.

Unlike before you can see there is a dedicated page to configure the Packet delay feature. Here is the screenshot of the new TOFFEE-Mocha updated Packet Delay settings page:

Updated TOFFEE-Mocha Big-Picture Page:
With the new features in place, I need to update the Big-Picture page. With more features in place, I need to organize the content (or settings) shown in the big-picture. So I categorized the Packet Drop settings and Packet Delay settings in the big-picture as shown below:

Live testing of TOFFEE-Mocha Random Packet Drop feature and test results: I did a simple setup with my PC configured as a TOFFEE-Mocha WAN Emulation device. And two laptops connected to the PC's two NIC cards. This way I can send traffic via TOFFEE-Mocha. I enabled the Random Packet drop feature and did three sample tests with drop factor value 1, drop factor value 2 and then finally drop factor value 3. As you can see below statistics depending on the drop factor you can see the probability of packets getting dropped is being adjusted. Here is the live statistics of the same.

And you can see the overall consolidated report of the same in the TOFFEE-Mocha Home page.

I have capture a live video (and video-log) of these tests so that you can watch it live in my Youtube video below. Along with the same I have also discussed the above features which I have so far supported and the overall project update.

Here is my Youtube VLOG of the same:

My sample Wireshark packet capture files for research ↗
Saturday' 13-Mar-2021
I have a huge repository (or collection) of sample Wireshark packet capture files for reference. I use them extensively for research and development of TOFFEE as well to understand various protocol PDUs and protocol standards. I personally collected various test captures via Wireshark during my test and experimental research setup during the course of TOFFEE development. Say if you are a student and learning Networking and or say VoIP data and VoIP packets, you can analyse my VoIP sample Wireshark captures. Or in other case assume you are doing some quick research (or development) and want to refer few handful of VoIP packets then you can download and analyse my sample packet capture files.

Saturday' 13-Mar-2021
Here is my first software development update of TOFFEE-Butterscotch. In my first TOFFEE-Butterscotch news update I have introduced about TOFFEE-Butterscotch research, project specifications, use-cases, etc. Introducing TOFFEE-Butterscotch Alerts: These are simple packet counters which corresponds to the filter type. For example if the incoming TCP-SYN packets are blocked then its corresponding alert counter will increment whenever such a packet arrives and gets filtered (dropped).

TOFFEE Benchmarks :: TOFFEE-1.1.28 ↗
Saturday' 13-Mar-2021
Here is the TOFFEE WAN Optimization benchmarks of the TOFFEE version: TOFFEE-1.1.28. This is the current TOFFEE development version till date (2-Jul-2016). This is a HPC TOFFEE variant meant for high-end custom build servers and high-end desktops (i.e High Performance Computing a.k.a HPC). TOFFEE built this way often needs customized kernel compilation and build such as processor specific and hardware specific tune-ups since it is highly CPU intensive (if not offloaded via Hardware Accelerator Cards).

Live demo - Data Transfer - High bandwidth to Low bandwidth ↗
Saturday' 13-Mar-2021
I always wanted to do some real experiments and research on packet flow patterns from High-bandwidth to Low-bandwidth networks via networking devices. This is something can be analyzed via capturing Network stack buffer data and other parameters, bench-marking, and so on. But eventually the data-transfer nature and other aspects is often contaminated due to the underlying OS and the way Network stack is implemented. So to understand the nature of packet flow from Higher to Lower bandwidth and vice-versa such as Lower to higher bandwidth, I thought I experiment with various tools and things which physically we can observe this phenomena.

TOFFEE-Mocha WAN Emulation software development - Update: 19-July-2016 ↗
Saturday' 13-Mar-2021
Today I refined the first page consolidated report graphs. TOFFEE-Mocha (unlike TOFFEE) is a WAN Emulator, so the graphs are supposed to highlight this purpose and should display the overall network activity. Unlike TOFFEE, the TOFFEE-Mocha report should contain in general what is received versus what is sent across the wire. In case if the packet drop feature is enabled, you should see few missing bytes and packets. Similarly in future I may support packet duplication feature, in that case you may see more packets/bytes sent versus the packets/bytes actually received.
