DOCUMENTATION 》 TOFFEE with Hardware Compression and Decompression Accelerator Cards

You can build a basic TOFFEE WAN Optimization hardware completely in software layer (i.e its networking data-plane and control-plane). And if you are a product manufacturer you can make commercial WAN Optimization products with TOFFEE with software layer alone. And if you choose to improve its performance, you can use any third-party PCIe Compression Accelerator cards.

Here is the TOFFEE system architecture with and without hardware accelerator card (i.e Hardware offload). Hardware offload will greatly reduce the load on general purpose CPU (which is your software/OS layer) and the core data optimization operation such as loss-less compression (sometimes even encryption) is done within a dedicated Hardware Accelerator card (or chip) as shown below.

In this case TOFFEE will work as an WAN Optimization framework. With this framework you can architect your entire commercial WAN Optimization product series. You need to modify TOFFEE Linux kernel modules (and APIs) so that it no longer choose kernel's LZ77, LZO or LZ4 software compression libraries (which is CPU bound), instead point to the hardware accelerator card vendor provided kernel's driver/library APIs. This makes packet data compression within TOFFEE Linux Kernel module CPU bound to dedicated co-processor hardware compression accelerator card bound.

It is a well known fact that Linux Kernel's Kernel modules are not great at scaling with multiple CPU Processor Cores. So in a systems architecture point of having more CPU cores in a TOFFEE WAN Optimization device gives no significant advantage. The per-core CPU performance is what required for a workload like TOFFEE packet data optimization. So if architect a high-end WAN Optimization device you need to consider hardware acceleration offload if feasible.

For example: Here is a general purpose AHA AHA363PCIE0301G 5Gbs GZIP Compression/Decompression Accelerator Card. Typical applications (or use-cases) of this card could be Storage Arrays, Load Balancers, WAN Optimization, Web Servers, Data Analytics, etc.

TOFFEE-Mocha WAN Emulation software development - Update: 20-Oct-2016 ↗
Saturday' 13-Mar-2021
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.

Saturday' 13-Mar-2021
Currently what we have is a single homogeneous (sort of) WWW Internet. Which we can consider as a single-dimensional network. What I propose is that we can create complete independent multiple Internets with each Internet having its own IP-address space, Domain namespace and an authority to manage Domain names. And these networks/Internets can be entirely IPv4 only based or IPv6 only based.

CDN Hosting ↗
Saturday' 13-Mar-2021
It is quite interesting that there are few web hosting firms are offering direct CDN based hosting services. Since it is a direct CDN based hosting, it is cheap, extremely easy or transparent CDN service. It is transparent, since each time you publish your content in the hosting web-server (origin server), it is immediately is in sync automatically in the user-serving CDN caching machines. Since the hosting vendor and the CDN vendor are all the same, it is also easy to use their services. There is no incompatibility issues, interoperability issues, and better integrated analytics, are all the benefits of CDN Hosting services.

When you choose to use your Raspberry Pi device as your IoT based remote weather station or if you are building Linux kernel (like kernel compilation) within the same, you need a good uninterrupted power source (UPS). But if you are using it on site or in some research camping location you can choose to power your Raspberry Pi device with your custom off-grid solar power source.
