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.

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.

TOFFEE-Mocha WAN Emulation software development - Update: 18-June-2016 ↗
Saturday' 13-Mar-2021
In the previous update (17-Jun-2016) I discussed about the upcoming new Random Packet drop feature along with other completed features. Now I completed the entire TOFFEE-Mocha Random packet drop feature. I completed all the kernel components and the UI support of the same. And to make GUI settings more organized I split the earlier Basic-Settings page into two separate pages namely: Packet Drop and Packet Delay. So this way it is simple to understand settings according to their functionality.

Off-Grid Solar Power System for Raspberry Pi ↗
Saturday' 13-Mar-2021
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.
