Introducing the NPU
Lag and Latency Reduction technology (LLR) uses a custom chipset called the Network Processing Unit (NPU) to allow parts of the game to run inside the Killer NIC. The NPU acts as a co-processor dedicated to running the networking portion of games and other applications.

A New Networking Model
LLR technology is completely Plug & Play, and works in all games. LLR literally bypasses the traditional Windows Networking Stack, enabling an entirely new game-optimized model of networking. The new networking model means there is a hardware interrupt for every gaming network packet, giving network traffic unprecedented speed and priority in your gaming PC.

Separating Networking and Graphics for Smoother Gameplay.
Games check the network for new data constantly – simple, but important checks ranging from “Is he shooting at me?” to “Is that door open or closed?” These checks are mixed with graphics and frames showing the result of the question (e.g. a closed or open door). LLR can answer these questions in just one CPU instruction. With LLR, your game has effectively separated graphics from networking. It can now dedicate more instructions to the other tasks – graphics and gameplay – that smooth your overall experience, especially during intense action.

Attacking Game Lag Where it Lives
Game Lag is a system problem, with sources in the PC, network, and server. Bigfoot Networks is developing new technologies that will address lag and latency in all three of these areas.

Lag and Latency Reduction (LLR2)
The LLR2 SDK helps developers and middleware providers optimize their titles and technologies to existing Killer NPUs and the upcoming Game Server Accelerator. LLR2 contains simple Killer optimization code, as well as cool new tools like hardware-based packet compression and packet encryption to reduce network latency. Game developers are using the LLR2 SDK to make their games work better with Killer, and one of our partners, Emergent Game Technologies, is even integrating LLR2 support into their latest game engines to be used in hundreds of future game titles.

Game Server Accelerator (GSA) – Server-side optimization for Everybody
Our Game Server Accelerator puts Killer technology on the server side, for enhanced performance during heavy loads. Just like our client-side NPUs, the GSA gets networking out of the way of the game, allowing game servers to distribute the extra resources for smoother operation. MMO servers can have more concurrent players per zone without lag, while FPS game servers can have more combatants without sacrificing action.

FNTorrent
FNTorrent uses your Killer NPU to download bit torrents and store them on a USB drive attached directly to your gaming NIC. You can even download while you game, and since the downloaded files are stored on a USB drive attached directly to the back of the Killer NIC, the files never touch your system. You can download gigabytes of files with zero impact to your game.

FNFirewall
FNFirewall uses the popular and effective Open Source iptables firewall found in Linux and provides you with a Windows(tm)-based front end. This firewall runs completely inside the Killer NPU, giving you added security by blocking malicious attacks before they even hit your PC's bus. Advanced iptables users can write their own scripts or use it directly using the FNA SDK.

FNA SDK
The FNA Software Development Kit (SDK) includes an open-source compiler, a copy of our custom Linux distribution, and a small set of rules that'll help anyone write or port Linux applications to the Killer NPU. Writing an FNApp is as easy as recompiling your source for Killer's flavor of Linux and pressing go. Additionally, these tools can enable your FNApp to seamlessly communicate with a Windows control application that runs on your Windows desktop.
