Abstract: A Mobile Wireless Broadband Network Interface Card (MWBNIC) for networking electronic devices on a wireless broadband spectrum. The MWBNIC is built into electronic devices as a connecting modem or plugged in via external device ports such as USB. A microprocessor chip attached to a circuit board with a network packet controller coupled to a dedicated cache memory utilized to temporarily store the last N data packets from a node for networking WIFI maintains packet continuity. The network comes with protocols that control packet processing. The MWBNIC embedded packet control protocol (PCP) pushes, pops, compares and deletes packets from cache when a device is in motion. The PCP is connected to a mechanism for determining bandwidth on nodes, another mechanism for switching frequency to that of the next K-Node to connect to and a pre-determined connectivity data set that directly connects the modem in motion are means for networking broadband spectrum.

Abstract: Systems and methods for providing an integrated or Smart NIC-based hardware accelerator for a network security device to facilitate identification and mitigation of DoS attacks is provided. According to one embodiment, a processor of a network security device receives an application layer protocol request from a client, directed to a domain hosted by various servers and protected by the network security device. The application layer protocol request is parsed to extract a domain name and a path string. The hardware acceleration sub-system updates rate-based counters based on the application layer protocol request by performing a longest prefix match on the domain name and the path string. When a rate threshold associated with the rate-based counters is exceeded, a challenge message is created and transmitted to the client, having embedded therein the application layer protocol request; otherwise the application layer protocol request is allowed to pass through the network security device.

Abstract: A novel design of a gateway that handles traffic in and out of a network by using a datapath pipeline is provided. The datapath pipeline includes multiple stages for performing various data-plane packet-processing operations at the edge of the network. The processing stages include centralized routing stages and distributed routing stages. The processing stages can include service-providing stages such as NAT and firewall. The gateway caches the result previous packet operations and reapplies the result to subsequent packets that meet certain criteria. For packets that do not have applicable or valid result from previous packet processing operations, the gateway datapath daemon executes the pipelined packet processing stages and records a set of data from each stage of the pipeline and synthesizes those data into a cache entry for subsequent packets.

Abstract: A method for offloading packet encapsulation for an overlay network is provided. The method, at a virtualization software of a host, sends a mapping table of the overlay network to a physical network interface controller (NIC) associated with the host. The mapping table maps the identification of each of a set of virtual machine (VM) of a tenant on the host to an identification of a tunnel on the overlay network. The method, at the virtualization software, receives a packet from a VM of the tenant. The method sends the packet to the physical NIC. The method, at the physical NIC, encapsulates the packet for transmission over the overlay network by using the mapping table. The method of claim also tags the packet by the virtualization software as a packet that requires encapsulation for transmission in the overlay network prior to sending the packet to the physical NIC.
