NEWS & UPDATES 》 TOFFEE-Mocha WAN Emulation software development - Update: 1-July-2016

This is my first Software Development update after the first TOFFEE-Mocha x86_64 and Raspberry Pi release. I got few emails from various users across the world for few new feature requests.

Today I got a feature request from Jonathan Withers. Jonathan is from a company called MultiWave Australia. He said he is able to get the TOFFEE-Mocha Raspberry Pi setup up and with that he is able to emulate geostationary satellite link. But he requested me is there a way to extend the constant packet delay from 40mS to 500mS. So as a part of his request I supported the same in the current ongoing development version of TOFFEE-Mocha.

Apart from this I supported a new feature called Random Packet Delay feature. With this feature if enabled, users can skip packet delay of few packets. This can be extremely useful in case if you want to simulate any bursty dynamic network packet flow. The probability of the same can be controlled via Random Packet delay factor variable. If it is set value 1, more and more packets may skip packet delays (both constant and random), and if it is set to value 5, 6 or 10, then the probability of skipping delays will reduce. You can use this setting in combination with packet delays and packet drop features.

Random packet delay also may simulate a sort of buffered packet flow. Sometimes due to packets getting accumulated in network device buffers few tend to arrive faster than others. Although the entire network link speed is governed by the overall physical layer technology such as wireless, or wired, copper vs fiber, etc. We can see this behaviour in a simple ping test. Few packets tend to arrive faster than others. And it is highly random and unpredictable the exact response time of each ping packet. A Random packet delay feature will contribute this effect in a pure WAN simulation link built with TOFFEE-Mocha.

So in my next upcoming TOFFEE-Mocha release I may include all these new features and updated old features. If you are in need of any specific feature (or scenario) you can kindly let know. If plausible and feasible I can support the same and release as a part of my upcoming TOFFEE-Mocha release. Kindly stay tuned !

Update: 7-July-2016: I did various tests of these new TOFFEE-Mocha features discussed above. And you can find detailed test cases and corresponding test results of the same: TEST CASES :: TEST RESULTS :: TOFFEE-Mocha-1.0.14 Development version

When you choose to use your Raspberry Pi device as your IoT based remote weather station or if you are building Linux kernel (like kernel compilation) within the same, you need a good uninterrupted power source (UPS). But if you are using it on site or in some research camping location you can choose to power your Raspberry Pi device with your custom off-grid solar power source.

TrueBench is an unique open-source benchmarking system in which the core system performance and efficiency parameters are measured at extreme high resolution in the order of several million/billion ยต-seconds for a given specific task. TrueBench is a part of The TOFFEE Project research. With TrueBench Raspberry Pi 3, Raspberry Pi 2B, Raspberry Pi 2 and other embedded SoC devices are benchmarked and you can do a comparative analysis with standard mainstream x86 devices.

When you build a WAN Optimization device with TOFFEE the entire packet processing (data optimization) takes place in software layer or in other words more precisely Operating System kernel space. However if you have any compression or encryption hardware accelerator hardware card the parts of the TOFFEE packet processing modules can be offloaded to hardware layer and thus improving its efficiency.

TOFFEE-Mocha WAN Emulation software development - Update: 15-July-2016 ↗
Saturday' 13-Mar-2021
Today I completed doing all the changes which are meant for the new upcoming TOFFEE-Mocha release. I have increased the resolution and the range of all factor variables. Instead 1 to 10 range now they have a range of 1 to 30. Unlike before the value 1 means it is lot more intense (or in some cases less intense) and the uppermost value 30 means lot less intense (or in some cases lot intense).
