NEWS & UPDATES 》 Introducing TOFFEE-DataCenter

Since past couple of days I was having sleepless nights as I was working on a new TOFFEE WAN Optimization software variant called as TOFFEE Data-Center. Unlike existing TOFFEE TOFFEE Data-Center is specifically meant for Data Center, Cluster Computing, HPC applications. TOFFEE is built in Linux Kernel core. This makes it inflexible to adapt according to the hardware configuration. It does sequential packet processing and does not scale up well in large multi-core CPU based systems (such as Intel Xeon servers, Core i7 Extreme Desktop systems,etc). Apart from this since it is kernel based, if there is an issue in kernel, it may crash entire system. This becomes a challenge for any carrier grade equipment (CGE) hardware build.

The new upcoming TOFFEE Data-Center will have basic minimal kernel module plus TOFFEE user-space components. The entire packet processing is done within user-space. And these modules can be spawned according to the load, and system's hardware capabilities. In a typical scenario you can have 10-100 such threads executing simultaneously at any given point of time. If due to any reason if one thread crashes/fails, the other threads will continue to operate. And if required based on the load, new threads can be spawned dynamically. With high-speed load balancing systems, you can build a complete WAN Optimization hardware cluster(s) based on TOFFEE Data-Center variant.

Here is an example of TOFFEE Data-Center deployment in which TOFFEE Data-Center is deployed in one more many servers with optional load-balancers. Click HERE to know more about TOFFEE deployment scenarios and topology.
TOFFEE-DataCenter WAN Optimization

Initial Prototyping and Feasibility tests: A basic prototype and PoC (proof of concept) software is built to test this idea. With the prototype various scenarios are tested with different hardware platforms such as low-end mini-PC, an extreme Core i7 Gaming Desktop, and Intel Xeon server(s). With Xeon Server and Core i7 we can process up to 1-Gigabit Network speeds thus achieving almost wire-speed performance everything within software layer. Making it to work smoothly within software layer is a challenge but it is required for VM, SDN based WAN Optimization device builds.

Software Development standpoint: Unlike the existing TOFFEE, since the new TOFFEE Data-Center is user-space centric, I can do code build, compile, test, debug, bug-fix cycles at much higher rates. Since the architecture is discrete, in future any new components can be plugged in it on demand basis with/without significant code changes. TOFFEE Data-Center (like TOFFEE) can also be used with any hardware compression/acceleration cards. This way you can offload some amount of packet processing load and improve overall system performance.

TOFFEE Data-Center for VM/SDN/Cloud Applications: The TOFFEE Data-Center with its modular architecture is well suited for VM based builds, SDN and Cloud deployments. TOFFEE Data-center is highly portable code which makes it easier to port for any hardware platforms such as ARM, MIPS besides x86.

Hardware Requirements TOFFEE vs TOFFEE Data-Center: TOFFEE needs a good CPU with excellent per-core performance. Traditionally Linux Kernel itself (kernel space modules) is not good at scaling in multi-core/multi-cpu CPU platforms. Instead the user-space apps in a Linux System is good at scaling in multi-core/multi-cpu CPU scenarios. This is the main drawback which can degrade the performance of TOFFEE. But TOFFEE Data-Center is modular so it prefers average single core CPU performance, but more CPU cores since it works in user-space and the load is shared across multiple TOFFEE Data-Center user-space computing modules.

Release schedule of the new upcoming TOFFEE Data-Center: TOFFEE Data-Center is just started (as on 4-Aug-2016) and its a huge project. Once a basic, stable version is developed, as a part of initial first phase the same will be released soon once it is mature and stable. Here is my Youtube VLOG of the same:

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.

TOFFEE (and TOFFEE-DataCenter) deployment with VPN devices ↗
Saturday' 13-Mar-2021
In case if you need to deploy TOFFEE along with your existing VPN devices you can deploy the same as shown below. This will allow your VPN devices to encrypt your TOFFEE WAN Optimized network data. NOTE: Make sure about the VPN deployment topology done in the right order. Else TOFFEE (LAN side) may get VPN encrypted packets which may not be possible (and or difficult) to further optimize. Hence always make sure to deploy them in a topology suggested below so that TOFFEE devices are out of VPN tunnel.

TOFFEE Benchmarks :: TOFFEE-1.1.28 ↗
Saturday' 13-Mar-2021
Here is the TOFFEE WAN Optimization benchmarks of the TOFFEE version: TOFFEE-1.1.28. This is the current TOFFEE development version till date (2-Jul-2016). This is a HPC TOFFEE variant meant for high-end custom build servers and high-end desktops (i.e High Performance Computing a.k.a HPC). TOFFEE built this way often needs customized kernel compilation and build such as processor specific and hardware specific tune-ups since it is highly CPU intensive (if not offloaded via Hardware Accelerator Cards).

Today I have done a test setup so that I can able to connect my Android Samsung Tab via TOFFEE DataCenter. Below is my complete test topology of my setup. For demo (and research/development) context I configured TOFFEE DataCenter in engineering debug mode. So I do not need two devices for this purpose.

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.
