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

VPN Network Optimization via TOFFEE WAN Optimization ↗
Saturday' 13-Mar-2021
VPN Networks may degrade network performance due to various packet processing overheads such as encryption and by adding extra network protocol header(s) (such as IPv4/IPv6, IPSec, etc). This may inflate near MTU sized packets and causes excessive packet fragmentation. Here are the few examples of packet processing involved in a VPN (or a VPN like) Tunnel. With TOFFEE you can optimize these packets even before they get processed on to a VPN device. TOFFEE optimizes packet contents (application payload and transport headers) so that these TOFFEE optimized packets when they get processed by VPN devices (or VPN software stack) they may never need further packet fragmentation. Here is a deployment scenario of TOFFEE with VPN devices.

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.
