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:

Now I supported and finished complete GUI support of these parameters so that you can configure, store, reboot and the same will restore upon reboot. Besides I complete the TOFFEE-Mocha Big-Picture page. The Big picture is an interface where you can find all the configuration (or settings) of the TOFFEE-Mocha. This is almost similar to CISCO device show all command but in graphical representation. Sometimes a network admin can also print the Big Picture page and paste it near to the device to refer its settings.

TOFFEE-Mocha WAN Emulation software development - Update: 20-Oct-2016 ↗
Saturday' 13-Mar-2021
I was doing some specific tests in my TOFFEE and TOFFEE-DataCenter (WAN optimization) scenarios such as variable upload and download speeds. And I was also doing some experiments with speedtest.net and I did some of these tests with TOFFEE-Mocha. I realized there is a case that I can introduce asymmetric constant delays so that you can get different download speed and a different upload speed. And in some cases much faster download speeds and relatively slower upload speeds.

Detect and Monitor Failing Harddrive in Linux - My Seagate 500GB HDD Died ↗
Saturday' 13-Mar-2021
My 500GB Seagate Barracuda 7200RPM hard-drive suddenly started making mild clicking noise. I found this happening since morning. I was suspicious that something wrong in this drive and when I opened the Linux Disks app, I can find the cause of this issue. The disk is increasingly getting read errors. Besides I can see various other parameters such as Power-On Hours, Temperature, Head flying hours, etc.



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 (and TOFFEE-DataCenter) optimized Mobile Wireless Backhaul Networks ↗
Saturday' 13-Mar-2021
TOFFEE can be used to optimize expensive Wireless backhaul network infrastructure. TOFFEE can be deployed over existing slow or often outdated old backhaul networks too. This will leverage mobile ISPs and network service providers to reduce their bulk IT CapEx and OpEx Costs.

Assume you have two sites (such as Site-A and Site-B) connected via slow/critical WAN link as shown below. You can optimize this link by saving the bandwidth as well possibly improve the speed. However, the WAN speed can be optimized only if the WAN link speeds are below that of the processing latency of your TOFFEE installed hardware. Assume your WAN link is 12Mbps, and assume the maximum WAN optimization speed/capacity of Raspberry Pi is 20Mbps, then your link will get speed optimization too. And in another case, assume your WAN link is 50Mbps, then using the Raspberry Pi as WAN Optimization device will actually increase the latency (i.e slows the WAN link). But in all the cases the bandwidth savings should be the same irrespective of the WAN link speed. In other words, if you want to cut down the WAN link costs via this WAN Optimization set up, you can always get it since it reduces the overall bandwidth in almost all the cases (including encrypted and pre-compressed data).

Multi-dimensional (Multi-universe) Internet Technology - A Proposal ↗
Saturday' 13-Mar-2021
Currently what we have is a single homogeneous (sort of) WWW Internet. Which we can consider as a single-dimensional network. What I propose is that we can create complete independent multiple Internets with each Internet having its own IP-address space, Domain namespace and an authority to manage Domain names. And these networks/Internets can be entirely IPv4 only based or IPv6 only based.
