NEWS & UPDATES 》 TOFFEE-Mocha WAN Emulation software development - Update: 20-Oct-2016

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.

What I did in this version is that I extended the constant delay feature of TOFFEE-Mocha. Added a new variable to enable or disable the overall constant delay factor. So with this option you can now completely enable the constant delay or completely disable the same. It will still contain the old milli-seconds and micro-seconds delay which will add constant delay for each packet irrespective of its direction. And along with that it will include the new upload milli-seconds, micro-seconds and download milli-seconds, micro-seconds delay variables which will add delay respectively to upload/uplink (LAN to WAN) packets and download/downlink (WAN to LAN) packets.

If you set any of these (upload/download) delay parameters along with standard delay (milli-seconds, micro-seconds) then it is going to be a summation of overall delay. So from this version of TOFFEE-Mocha it is going to have a distinct LAN port and a distinct WAN port unlike earlier versions. If you see in my earlier documents (as well as news updates) I mentioned in the user guide stating that: "IMPORTANT NOTE: Since TOFFEE-Mocha device is a WAN emulator device you can configure any port as LAN port and WAN port. Swapping LAN and WAN ports in your deployment will not cause any issues." But not a case anymore starting from this version which should be released very soon.

Here is my screenshot of the same (which is still in development):

So this way you can add asymmetric delays which is a great tool when you are doing systematic tests and research scenarios such as fine-tuning your WAN Optimization device, a network test lab setup, investigating TCP acceleration parameters, TCP optimization and things like that. Strangely with some experiments with TOFFEE-Mocha I have even managed to get better TCP performance and ratings in my speedtest.net test results. Since essentially I am finding ways to optimize TCP Window scaling and make packet drop happen within LAN and self adjust TCP window/throttle rather than packets getting dropped in the WAN network (or Internet). Not only this will save your bandwidth but with this technique it may improve overall end-to-end network performance and higher bandwidth rates.

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

Here is my Youtube VLOG of the same:

Building my own CDN - Moving away from Joomla to non-Joomla website - Update: 01-Oct-2016 ↗
Saturday' 13-Mar-2021
Seems there are couple of Inmotionhosting servers are down. And one of the server includes The TOFFEE Project website hosted server. I was in touch with the Inmotionhosting team trying to resolve the same. I found a unique issue that all my website files are intact and the Joomla database. But the Joomla database tables are completely wiped out and missing. Besides there is also a sort of upgrade going on in their servers. Luckily I have the most recent backup of the entire website.

As a research experiment I replaced my Intel Core i7 5820K desktop PC with my Intel Celeron 1037U Mini-PC as my everyday desktop system. This is an attempt to reduce my overall monthly power consumption. As well an attempt to do feasibility tests and research to know how far Mini PC will dominate the market in future and to study the real potential of Mini PCs.

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.

Here is a step-by-step DIY to build your own Intel based Mini PC WAN Optimization Device with TOFFEE. I chose this below Intel Celeron Mini PC since it is fan-less aluminium case and as well it has 2 dedicated inbuilt Gigabit Ethernet ports. You can use one for LAN Network and one for WAN Network.
