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:

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.

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.

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.
