Release Notes:
NEWS :: First TOFFEE-Butterscotch Code Release

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.

For example you can optimize your slow and expensive 3G/4G Mobile networks:

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
TOFFEE_Butterscotch Login

Home page: Once you login you will get this first HOME page.

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.

Real time stats: Monitor real time data-consumption (or data-transferred) stats.
TOFFEE_Butterscotch Live performance stats

Big-picture: Anytime you can view and confirm your settings via Big Picture. Big Picture is a neat graphical illustration of your overall TOFFEE-Butterscotch settings. You can view any time as a reference or even print and file it as a record if you are a Network Admin.

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.

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.

Here is my first software development update of TOFFEE-Butterscotch. In my first TOFFEE-Butterscotch news update I have introduced about TOFFEE-Butterscotch research, project specifications, use-cases, etc. Introducing TOFFEE-Butterscotch Alerts: These are simple packet counters which corresponds to the filter type. For example if the incoming TCP-SYN packets are blocked then its corresponding alert counter will increment whenever such a packet arrives and gets filtered (dropped).

Software-Defined Wide Area Networking (SD-WAN) is a new innovative way to provide optimal application performance by redefining branch office networking. Unlike traditional expensive private WAN connection technologies such as MPLS, etc., SD-WAN delivers increased network performance and cost reduction. SD-WAN solution decouple network software services from the underlying hardware via software abstraction.

A study on WAN Optimization Techniques ↗
Saturday' 13-Mar-2021
There are various techniques with which one can optimize their WAN Network Data. Any long distance communication can be considered as WAN Network. A decade ago any network connecting two countries, considered as a WAN network, and a network within a city as MAN and soon. But these days in general any long distance communication is considered as WAN Network. Such as your Mobile communication networks, Satellite networks, Space Networks (Deep space networks), Trans-Atlantic cable networks, etc.




Building my own CDN - Google PageSpeed Insights - Update: 22-Jul-2016 ↗
Saturday' 13-Mar-2021
Ever since after I launched my new The TOFFEE Project website on 1-May'2016, I can see there is a steep increase in traffic. Soon after the launch when I monitored its Alexa rankings it was reporting about 12 Million or so. But once it is getting more and more traffic the Alexa rankings shot up and now currently it shows around 2 Million (as on 22-July-2016). Alexa is an excellent tool to monitor your overall website global ranking and indirectly its performance. Unlike Google Analytics which is bound one or other way into Google's SEO. Alexa gives you a second opinion about your website's growth.
