User Guide (Documentation)
TOFFEE-Butterscotch is a variant of TOFFEE can be used to save and optimize your Home/SOHO Internet/WAN bandwidth. Unlike TOFFEE (and TOFFEE-DataCenter) TOFFEE-Butterscotch is a non peer-to-peer (and asymmetric) network optimization solution. This makes TOFFEE-Butterscotch an ideal tool for all Home and SOHO users. Here is the deployment topology of TOFFEE-Butterscotch deployment. You can deploy the same either before your WiFi router or after your router whichever is feasible as shown below.

The TOFFEE-Butterscotch-1.0.11-rpi2-23-nov-2016 release is highly optimized and customized for Raspberry Pi 2/3 hardware platform and it is built within the standard Raspberry Pi Raspbian Jessie with PIXEL Operating System (version: 2016-09-23-raspbian-jessie.img).

Installation: TOFFEE-Butterscotch Raspberry Pi version is a complete disk image of Raspberry Pi Raspbian OS in which TOFFEE-Butterscotch is built and pre-installed. You can download the binary (the install image above), un-tar it and install on a microSD card which is around larger than or equal to 8GB capacity. Since this is the size of the microSD card upon which I built the TOFFEE-Butterscotch image.

You can follow the standard official Raspberry Pi guide for general Raspberry Pi OS image install steps: Installing operating system images

If you are using a Linux system you can do via dd command as shown below. Assume in this case the empty microSD card is "/dev/sdc"

[email protected]:~$ sudo dd bs=4M if=TOFFEE-Butterscotch-1.0.11-rpi2-23-nov-2016.img conv=sync,noerror of=/dev/sdc

Hardware :: Additional NIC Card Installation: You can use a USB2 to 100Mbps NIC card so that you can get totally two network ports as shown below. Once it is installed you can check and confirm via ifconfig command as shown below:

Configuration: Once you are done with Installation, you can boot TOFFEE-Butterscotch OS image. As you can see the entire Raspbian Jessie with PIXEL is customized so that it looks minimal and has this polished interface.

TOFFEE-Butterscotch GUI: You can now access the TOFFEE-Butterscotch GUI via your Google Chrome browser as shown below.
The default username is: root and the password is: welcome

URL: http://localhost/toffee_butterscotch

Basic Settings: You can do TCP throttle and Torrent traffic throttle as shown below. For more details kindly refer documentation/help in the page.
TOFFEE_Butterscotch Throttle TCP [CDN]
In my case the overall download and upload speed of my Internet connection is 55Mbps and 49Mbps so I am setting 60Mbps as my average WAN speed for better TCP performance via TCP throttle feature.

TOFFEE-Butterscotch future road-map: This is the first release of TOFFEE-Butterscotch open-source Bandwidth saver software. Currently as one can understand the features supported in the same are quite limited. But in future you should get more and more new features being supported in the same. If you need any specific features, you can post your new feature requests to me, and if they are plausible they should get supported in the same eventually.

TOFFEE-DataCenter :: Features Supported ↗
Saturday' 13-Mar-2021
Here is a list of TOFFEE-DataCenter features supported. TOFFEE-DataCenter currently supports some of the important features such as loss-less network data compression, Packet Deduplication (protocols/applications supported), Application Acceleration, TCP Acceleration, dynamic MTU optimization, data packaging, hardware offload support, etc.

TOFFEE-DataCenter WAN Optimization software development - Update: 13-Aug-2016 ↗
Saturday' 13-Mar-2021
Earlier the TOFFEE is intended to work on IoT devices, Satellite Networks, branch office/SOHO deployments. In most cases the users may deploy just one or couple of TOFFEE devices per site. But in the case of TOFFEE-DataCenter, users can scale-up deploying the same in multiple servers in a sort of distributed cluster computing scenario. Besides the core TOFFEE-DataCenter components (such as packet processing engine/framework), I need to do lot of changes in its Graphical User Interface (GUI) too to address these new requirements.

Saturday' 13-Mar-2021
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.

TOFFEE (and TOFFEE-DataCenter) deployment with web-proxy cache ↗
Saturday' 13-Mar-2021
If you want to deploy TOFFEE along with a web-proxy cache (such as Squid Proxy) you can deploy the same as shown below. TOFFEE does not cache files. TOFFEE does packet level network optimization. So if you want caching your web content you can use transparent mode web-proxy cache intercepting your WAN links. A web-proxy may reduce amount of data being processed (optimized) within these TOFFEE devices and so reduce the CPU overheads and improve its performance.

Saturday' 13-Mar-2021
One of the suggestions Google PageSpeed Insights tool suggested for The TOFFEE Project website is to minify the css and java script files. Minify Script files: When you read online about minification of your web script files, often they highlight file size savings and thus resulting faster download time and better website performance.

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).

TOFFEE-Mocha WAN Emulation software development - Update: 1-July-2016 ↗
Saturday' 13-Mar-2021
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.
