Abstract: Techniques for facilitating load balancing in distributed computing systems are disclosed herein. In one embodiment, a method includes receiving, at a destination server, a request packet from a load balancer via the computer network requesting a remote direct memory access (“RDMA”) connection between an originating server and one or more other servers selectable by the load balancer. The method can also include configuring, at the destination server, a rule for processing additional packets transmittable to the originating server via the RDMA connection based on the received reply packet. The rule is configured to encapsulate an outgoing packet transmittable to the originating server with an outer header having a destination field containing a network address of the originating server and a source field containing another network address of the destination server.

Abstract: Techniques are described herein that are capable of monitoring connectivity and latency of network links in virtual networks. For instance, a ping agent injects first ping packets into network traffic on behalf of hosts in the virtual network. The ping agent monitors incoming packets to identify first ping response packets, which are in response to the first ping packets, among the incoming packets. A ping responder rule that is included in inbound packet filter rules for a port in a virtual switch intercepts second ping packets in the network traffic. The ping responder rule converts the second ping packets into second ping response packets and injects the second ping response packets into outbound packet filter rules to be transferred to sources from which the second ping packets are received.

Abstract: Distributed computing systems, devices, and associated methods of packet routing are disclosed herein. In one embodiment, a method includes receiving, from a computing network, a packet at a packet processor of a server. The method also includes matching the received packet with a flow in a flow table contained in the packet processor and determining whether the action indicates that the received packet is to be forwarded to a NIC buffer in the outbound processing path of the packet processor instead of the NIC. The method further includes in response to determining that the action indicates that the received packet is to be forwarded to the NIC buffer, forwarding the received packet to the NIC buffer and processing the packet in the NIC buffer to forward the packet to the computer network without exposing the packet to the main processor.

Abstract: Distributed computing systems, devices, and associated methods of packet routing are disclosed herein. In one embodiment, a computing device includes a field programmable gate array (“FPGA”) that includes an inbound processing path and outbound processing path in opposite processing directions. The inbound processing path can forward a packet received from the computer network to a buffer on the FPGA instead of the NIC. The outbound processing path includes an outbound multiplexer having a rate limiter circuit that only forwards the received packet from the buffer back to the computer network when a virtual port corresponding to the packet has sufficient transmission allowance. The outbound multiplexer can also periodically increment the transmission allowance based on a target bandwidth for the virtual port.

The rule object has one or more conditions matching the one or more parsed header fields of the packet and a corresponding flow action. The method further includes generating a composite action by combining the flow actions individually corresponding to one of the matched rule objects from one of multiple layer objects and applying the generated composite action to the packet.

Abstract: Techniques are disclosed for communicating data in a virtualized environment comprising virtual machines executing on one or more computing devices. An underlying physical destination address of a virtual machine executing on a virtual network is changed from a first physical address to a second physical address. A traffic forwarder function is executed on a virtual switch within the virtual network. The traffic forwarder function is executed during a time threshold determined based on a reprogramming time for network devices in the virtualized environment to update the underlying physical destination address. A data packet addressed to the first physical address is by the traffic forwarder function on a network external to the virtual network. A destination address of the data packet is updated from the first physical address to the second physical address. The data packet is forwarded to the updated destination address.

Abstract: Micro-schedulers control bandwidth allocation for clients, each client subscribing to a respective predefined portion of bandwidth of an outgoing communication link. A macro-scheduler controls the micro-schedulers, by allocating the respective subscribed portion of bandwidth associated with each respective client that is active, by a predefined first deadline, with residual bandwidth that is unused by the respective clients being shared proportionately among respective active clients by a predefined second deadline, while minimizing coordination among micro-schedulers by the macro-scheduler periodically adjusting respective bandwidth allocations to each micro-scheduler.
