    摘要： One networking device includes a switch module, a server, and a switch controller. The switch module has ports with a communications interface of a first type (CI1) and ports with a communications interface of a second type (CI2). The server, coupled to the switch module via a first CI2 coupling, includes a virtual CI1 driver, which provides a CI1 interface in the server, defined to exchange CI1 packets with the switch module via the first CI2 coupling. The virtual CI1 driver includes a first network device operating system (ndOS) program. The switch controller, in communication with the switch module via a second CI2 coupling, includes a second ndOS program controlling, in the switch module, a packet switching policy defining the switching of packets through the switch module or switch controller. The first and second ndOS programs exchange control messages to maintain a network policy for the switch fabric.

    摘要： Systems are presented for processing packets in a network switch. One network device includes a processor, an Ethernet switch, a PCIe switch, and a packet processor. The processor is for executing a controller program, and the Ethernet switch is for switching packets among a ports. Further, the PCIe switch is coupled to the processor and the Ethernet switch, and the packet processor, coupled to the Ethernet switch and the PCIe switch, is operable to modify an application header of an incoming packet and send the incoming packet to one of the ports. The controller program is operable to configure the Ethernet switch and the packet processor to define processing of packets. The controller program is operable to send a first configuration rule to the Ethernet switch, the first configuration rule defining that packets of a network flow requiring header modification be forwarded to the packet processor.

    摘要： Methods, systems, and computer programs are presented for splicing a client-server connection. One method includes an operation for splicing a client-server network connection by creating a first network connection between the client and a network device and a second network connection between the network device and the server. The method includes an operation for configuring in the network device a network processing unit (NPU) with a first and second offsets for the first and second network connections respectively. The incoming packets for the first and second network connections are then sent to the NPU for processing, which processes the packets in hardware to achieve low packet latency. The NPU adjusts the sequence number of the incoming packets of the first and second network connections based on the respective first and second offsets. The incoming packets are then sent to the destination after being processed.

    摘要： Methods, systems, and computer programs are presented for networking communications. One method includes an operation for receiving a packet in a first format by a virtual driver providing a communications interface of a first type (CI1), the first format being for CI1. Further, the method includes an operation for encapsulating the packet in a second format by a processor, the second format being for a communications interface of a second type (CI2) different from CI1. In addition, the method includes an operation for sending the encapsulated packet in the second format to a switch module. The switch module includes a switch fabric, one or more CI1 ports, and one or more CI2 ports, and the switch module transforms the packet back to the first format to send the packet in the first format to a CI1 network via one of the CI1 ports in the switch module.

    摘要： Systems, methods, and computer programs are presented for managing network traffic. A network switch includes a switch fabric and a resource coherency and analytics engine (RCAE) coupled to the switch fabric. The RCAE includes one or more virtualizable resource groups (VRGs) for managing network traffic flow across a plurality of network switches on the network. Further, the RCAE is operable to add network entities to each VRG, add flows to each VRG, and add other VRGs to each VRG. A virtualizable resource control list (VRCL), associated with each VRG, identifies which network entities in the VRG can communicate with each other, which network entities in the VRG can communicate with network entities in other VRGs, and a guaranteed bandwidth for the VRG associated with the VRCL. Furthermore, the RCAE is operable to exchange messages with other RCAEs in other network switches to implement traffic policies defined by each VRCL.
