Techniques for Wi-Fi acceleration in residential gateways

A non-transitory computer readable medium having instructions stored thereon, execution of which by a computing device, cause the computing device to perform operations comprising:

• pre-configuring a controller to intercept a networking function programmed in a stack of a driver, wherein the controller and the driver are components of a kernel of an operating system executed by a host processor;
• monitoring a system call initiated by the driver to the kernel;
• checking whether the system call is a request for the networking function;
• forwarding the system call for the networking function to a packet processor;
• executing the networking function, only in the packet processor, to provide a processed packet;
• mapping, by the controller, a media access control (MAC) address of a subscriber device to a service set identifier (SSID) when multiple different wireless local area networks (WLANs) are supported by the residential gateway;
• and
• routing, by the driver, the processed packet to a destination WLAN based on the mapping.

A residential gateway connected to a plurality of subscriber devices communicating through a wireless local area network (WLAN), the residential gateway comprising:

• a packet processor configured to execute only a networking function;
• and
• a host processor configured to execute an operating system, wherein a kernel of the operating system is configured to host a controller and a driver, wherein the controller is configured to:
• monitor a system call initiated by the driver to the kernel;
• check whether the system call is a request for the networking function;
• forward the system call for the networking function to the packet processor;
• allow execution of the system call by the host processor only if the system call is not a request for the networking function;
• and
• map a media access control (MAC) address of a subscriber device from among the plurality of subscriber devices to a service set identifier (SSID) when multiple different WLANs are supported by the residential gateway;
• wherein the driver is configured to route a processed packet from the packet processor or the host processor to a wireless network interface network card (WNIC) for routing onto a destination WLAN based on the mapping when a final destination of the processed packet is the WLAN.
