NEWS & UPDATES 》 TOFFEE-Mocha WAN Emulation software development - Update: 16-June-2016

I started TOFFEE-Mocha WAN Emulation software development on 1-June-2016. I took the existing TOFFEE components as a base. Although the TOFFEE-Mocha is entirely an independent fresh Open-Source WAN Emulation solution. Ever since I am in the process of defining and inventing features. So far I come up with the most important feature which is expected to be present in any WAN Emulation software is the packet delay option.

First I supported what is called as "Constant Packet Delay" to introduce per-packet (or inter packet) delay in the combination of milli-seconds and micro-seconds. This feature once I fully implemented I tested with file-downloads (via TCP) and bulk ping (ICMP) 1000-bytes packet size and found it is working flawlessly as expected. But what I need is also an innovative feature with which we can control the packet rate based on its size. Such as more delay for a packet which is around 1000-bytes and less delay for a packet which is just around 100-bytes. So I introduced another feature called as "Packet Dynamic Delay". With this feature now I can dynamically control the rate of the packet flow proportional to the size of the packet. And with the packet-dynamic-delay-factor variable you can also adjust its delay factor. Higher the delay-factor set, lower is going to be the packet dynamic delay and vice-versa. And you can also set delays combination of constant and dynamic packet delay parameters.

As one can understand these are cases which we cannot easily configure via any existing Linux tools (user-space and or kernel-space features). And if you need a highly versatile WAN Emulation testing software you need features such as these. I may continue to work on probably couple of more feature before my first TOFFEE-Mocha release which is scheduled on 1-July-2016. Until then stay tuned.

If you have any feature requests expected to be supported on TOFFEE-Mocha software you can kindly send me your ideas and suggestions.

TOFFEE-Mocha WAN Emulation software development - Update: 18-June-2016 ↗
Saturday' 13-Mar-2021
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.

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.

Benchmark Raspberry Pi and other embedded SoC with TrueBench ↗

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 µ-seconds for a given specific task. TrueBench is a part of The TOFFEE Project research. With TrueBench Raspberry Pi 3, Raspberry Pi 2B and Raspberry Pi 2 are benchmarked and you can do a comparative analysis with standard mainstream x86 devices.

Communication data network standards and data transfer speeds :: Chart ↗

Here is a complete chart comprising popular communication data network standards and their respective transfer rates. I hope this reference chart will help network engineers and network software developers while performing networking tests and experiments, building WAN/network products, building WAN simulated networks of a specific standard and so on. This may also helps us to track technological advancements of communication data networks.

Raspberry Pi as a Networking Device ↗
Saturday' 13-Mar-2021
Raspberry Pi is often used as a single board computer for applications such as IoT, hobby projects, DIY, education aid, research and prototyping device. But apart from these applications Raspberry Pi can be used for real-world applications such as in making a full-fledged networking devices. Raspberry Pi is a single board ARM based hardware which is why it is also classified as ARM based SoC. Since it is ARM based it is highly efficient, tiny form-factor and lower in power consumption with moderate computational power. This will allow it to work several hours on emergency battery backup power supply such as low-cost domestic UPS and or some renewable energy source, which is a prerequisite for a typical networking device.

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.
