A virtual network comprising virtual machines executing at a computing environment is implemented. A software defined networking (SDN) appliance is configured to provide a connection to computing resources via a virtual network of a virtual computing environment. The SDN appliance includes a network interface card that are operable to interact with multiple field-programmable gate array (FPGA) devices are configured to be a hardware acceleration device for processing data traffic, and the FPGA device is configured to ingress a packet to a dataflow on one port and egress the packet from a different port associated with a different dataflow.

Fault tolerance for SDN gateways using network switches

Systems and methods for enabling access to dedicated resources in a virtual network using top of rack switches are disclosed. A method includes a virtual filtering platform encapsulating at least one packet, received from a virtual machine, to generate at least one encapsulated packet comprising a virtual network identifier (VNI). The method further includes a TOR switch: (1) receiving the at least one encapsulated packet and decapsulating the at least one encapsulated packet to create at least one decapsulated packet, (2) using the VNI to identify a virtual routing and forwarding artifact to determine a virtual local area network interface associated with the dedicated hardware portion, and (3) transmitting the at least one decapsulated packet to the dedicated hardware portion based on at least one policy provided by a controller, where the at least one policy comprises information related to a customer of the service provider.

Enabling access to dedicated resources in a virtual network using top of rack switches

A virtual network comprising virtual machines executing at a computing environment is implemented. A software defined networking (SDN) appliance is configured to provide a connection to computing resources via a virtual network of a virtual computing environment. The SDN appliance is configured to apply policies of the virtual computing environment to data traffic on the virtual network. The SDN appliance is operable to interact with multiple network devices that are configured to act as a hardware acceleration device for processing data traffic. Virtual addresses are assigned to the network devices. The SDN appliance executes a virtual switch configured to identify data traffic sent to or received from a host and act as a proxy for the network devices and respond on their behalf.

Software defined networking operations for programmable connected devices

Proxy networks enable a source to send traffic to one or more targets through a set of nodes operating as proxies. However, proxy networks are typically nonselective (often by design), and do not enable a source to specify properties of the nodes selected as proxies to send traffic to the target. Presented herein are proxy network techniques that enable sources to specify node properties in a target request, and that utilize a set of node managers for respective subsets of nodes. For a target request specifying selected node properties, the node managers may select as proxies nodes having the node properties specified in the target request. Additionally, the techniques presented herein promote the flexibility of the proxy network (e.g., adding groups of nodes, expanding the variety of nodes and node properties, and sending various forms of traffic using any protocol to various topics on behalf of many and various sources).
