  • Patent number: 10819627
    Abstract: A method and device for realizing automatic stacking of network devices are disclosed. According to an example of the method, when a network device determines its device role, the network device may send a first neighbor discovery message to a neighbor device and receive a second neighbor discovery message sent by the neighbor device. Next, if it determines that a topological structure between the network device and the neighbor device changes according to the second neighbor discovery message, the network device may determine whether a stacking condition to trigger stacking the network device and the neighbor device is satisfied or not. If the stacking condition is satisfied, the network device may further determine a stacking configuration for stacking the network device and the neighbor device. Then the network device may stack the network device with the neighbor device according to the stacking configuration.

  • Patent number: 10795718
    Abstract: A technique is described herein for updating the logic used by a hardware accelerator provided by a computing device. In one implementation, the technique provides a pass-through mode which allows a virtual machine (provided by the computing device) to directly interact with the hardware accelerator. Upon the commencement of an updating operation, the technique instructs an emulator to begin emulating the function(s) of the hardware accelerator and the resultant effects of these functions, without interaction with the actual hardware accelerator. When the updating operation finishes, the technique re-enables the pass-through mode. By virtue of the above-summarized manner of operation, the technique allows the computing device to perform the function(s) associated with the hardware accelerator while the hardware accelerator is being updated. In one case, the technique disables the pass-through mode by modifying address-mapping information used by the virtual machine to access system physical addresses.

  • Patent number: 10778508
    Abstract: Bypass switch systems and methods are disclosed for in-line monitoring of network traffic. Network ports receive ingress packets from a network and transmit processed packets as egress packets back to the network. Tool ports send the ingress packets to in-line network tools and receive the processed packets back from the in-line network tools. Tap output ports operate in a first configuration setting to output copies of ingress packets received by a network port and in a second configuration setting to output copies of processed packets transmitted as egress packets by a network port. For one embodiment, copies of ingress packets received by a network port are output through one tap output port, and copies of processed packets transmitted as egress packets by a network port are output through another tap output port. These packets copies are then analyzed to evaluate the operation of the in-line tools.

One method operation creates virtual switches in one or more hosts in the virtual infrastructure. Each port in the virtual switches is associated with a private allocated network (PAN) from a group of possible PANs. In one embodiment, one or more PANs share the same physical media for data transmission. The intranet traffic within each PAN is not visible to nodes that are not connected to the each PAN. In another operation, the method defines addressing mode tables for the intranet traffic within each PAN. The entries in the addressing mode tables define addressing functions for routing the intranet traffic between the virtual switches, and different types of addressing functions are supported by the virtual switches.

  • Patent number: 10672095
    Abstract: Techniques for improving data transfer in a system having multiple accelerated processing devices (“APDs”) are described herein. In such a system, multiple APDs are coupled to a processor (e.g., a central processing unit (“CPU”)) via a general interconnect fabric and to each other via a high speed interconnect. The techniques herein increase the effective bandwidth for transfer of data between the CPU and the APD by transmitting data to both APDs through the portion of the interconnect fabric coupled to each respective APD. Then, one of the APDs transfers data to the other APD or to the processor via the high speed inter-APD interconnect. Although data transferred “indirectly” through the helper APD takes slightly more time to be transferred than a direct transfer, the total effective bandwidth to the target is increased due to the high-speed inter-APD interconnect.

  • Patent number: 10635474
    Abstract: A new approach is proposed that contemplates systems and methods to support virtio-based data packet path optimization for live virtual machine (VM) migration for Linux. Specifically, a data packet receiving (Rx) path and a data packet transmitting (Tx) path between a VM running on a host and a virtual function (VF) driver configured to interact with a physical network device of the host to receive and transmit communications dedicated to the VM are both optimized to implement a zero-copy solution to reduce overheads in packet processing. Under the proposed approach, the data packet Tx path utilizes a zero-copy mechanism provided by Linux kernel to avoid copying from virtio memory rings/Tx vrings in memory of the VM. The data packet Rx path also implements a zero-copy solution, which allows a virtio device of the VM to communicate directly with the VF driver of the network device while bypassing a macvtap driver entirely from the data packet Rx path.

  • Patent number: 10592447
    Abstract: The described technology is generally directed towards accelerating data handling in a cloud data storage system by using smart network interface cards (SmartNICs) at the nodes. Instead of copying data to kernel space, many input/output (I/O) operations can be handled primarily by the SmartNIC, using the SmartNIC's memory. For example, mirrored data writes can be sent directly from the SmartNIC's memory associated with the node handling the write to other nodes, without first copying the data to kernel space. Object reads can be handled at a node by having segments of the object queued, in order, in the node's associated SmartNIC's memory, and sent to a requesting client without having to be copied to the handling node's kernel space, unless low memory conditions exist in the SmartNIC's memory.

The compositions of the sequences of the encoded packets can be predetermined without the content of the packets; and the channel-encoded packets can be generated from the original packets on-the-fly by the transmitters of the channels during transmission. When a sufficient number of packets have been received via the channels, a recipient may terminate their transmissions.

  • Patent number: 10560431
    Abstract: A request to establish an encrypted VPN connection between a network external to a provider network connected to the provider network via a dedicated direct physical link and a set of resources of the provider network is received. A new isolated virtual network (IVN) is established to implement an encryption virtual private gateway to be used for the connection. One or more protocol processing engines (PPEs) are instantiated within the IVN, address information of the one or more PPEs is exchanged with the external network and a respective encrypted VPN tunnel is configured between each of the PPEs and the external network. Routing information pertaining to the set of resources is provided to the external network via at least one of the encrypted VPN tunnels, enabling routing of customer data to the set of resources within the provider network from the external network via an encrypted VPN tunnel implemented over a dedicated direct physical link between the external network and the provider network.

  • Patent number: 10511546
    Abstract: In one example, a management component executing on a single-chassis network device configures a virtual node with an abstract fabric interface having, as a destination address, identifiers of packet processors (e.g., PTFE-IDs) assigned to the virtual node on the other end of the abstract fabric interface. The management component of the single-chassis network device pre-creates an underlay network by using the fabric links at the packet processor. When the management component creates and connects an abstract fabric interface on the virtual nodes, the management component forms an overlay network and attaches the overlay network to the underlay network, e.g., by programming the forwarding plane packet processor, to connect the virtual nodes. However, users of the network device, external devices, and routing protocols will not view the abstract fabric interface as an overlay interface, but as a regular Ethernet interface (e.g., a Gigabit Ethernet interface).
