  • Patent number: 10419338
    Abstract: A configurable directional 2D router for Networks on Chips (NOCs) is disclosed. The router is well suited for implementation in programmable logic in FPGAs, and achieves theoretical lower bounds on FPGA resource consumption for various applications. The router may employ an FPGA router switch design that consumes only one 6-LUT or 8-input ALM logic cell per router per bit of router link width. A NOC comprising a plurality of routers may be configured as a directional 2D torus, or in diverse ways, network sizes and topologies, data widths, routing functions, performance-energy tradeoffs, and other options. System on chip designs may employ a plurality of NOCs with different configuration parameters to customize the system to the application or workload characteristics. A great diversity of NOC client cores, for communication amongst various external interfaces and devices, and on-chip interfaces and resources, may be coupled to a router in order to efficiently communicate with other NOC client cores.

  • Patent number: 10412049
    Abstract: A packet interceptor monitors GTP traffic for control signaling and data plane traffic. The interceptor reroutes a packet by modifying its IP addresses and forwards the packet to a packet data network gateway server. The server receives the GTP-U packet, performs identification based on the synchronized GTP session information, decapsulates the GTP tunnel information from the GTP-U packet and sends to either a proxy server or the destination application server directly. The proxy server performs message filtering, stores packet contents into storage and forwards the packet out to the destination application server. The filtering function of the proxy server can be trained and enhanced with machine learning algorithms. Thus, the proxy server can automatically detect the traffic type and allow or block the packet based on the detection result.
