Network virtualization platform for packet processing and forwarding
A recently granted patent (Publication Number: US12015504B1) discloses a computing device designed to receive packets from user equipment (UE) and communicate with other computing devices. The device includes a processing unit, memory unit, network interface card (NIC), and a network virtualization platform operating on a hardware layer. The platform accommodates multiple virtual network applications and includes an application layer with virtual network applications and a virtual network layer with a user plane function (UPF) plugin. The UPF plugin performs rule matching based on packet headers to determine whether to offload the packet to a virtual network application for services or re-package and forward it to another computing device.
Furthermore, the patent describes a method for processing UPF packets executed by the computing device, involving steps such as receiving packets from a UE, performing rule matching by the UPF plugin based on packet headers, and determining whether to offload or re-package the packet. The method also includes additional steps like decapping packets, parsing packet headers, and determining the Protocol Data Unit (PDU) session anchor based on UE requirements. The NIC, described as a smart network card supporting hardware offload functions, directly decaps packets, parses headers, and transmits them to the UPF plugin for further processing. Additionally, a device driver facilitates moving packets from the NIC to the memory unit using a zero-copy technique, enhancing efficiency in packet processing within the computing device.
