Abstract: The present disclosure includes systems, methods, and computer-readable mediums for discovering capabilities of local and remote hardware (HW) accelerator cards. A local hardware (HW) accelerator card may provide, via a communication interface, a listing of acceleration services from the local HW accelerator card. The listing of acceleration services may include a first set of acceleration services provided by one or more accelerators of the local HW accelerator card and a second set of acceleration services provided by one or more accelerators of a remote HW accelerator card. A workload instruction defining a workload for processing by at least one of the acceleration services of the second set of acceleration services may be received from a processor of a computing device. The workload instruction may be forwarded to the remote HW accelerator card.

Abstract: A method for providing cloud network reachability analysis includes receiving a reachability query requesting a reachability status of a target including a packet header associated with a data packet. The packet header includes a source IP address and a destination IP address. The method also includes generating one or more simulated forwarding paths for the data packet based on the packet header using a data plane model. Each simulated forwarding path includes corresponding network configuration information. The method includes determining the reachability status of the target based on the one or more simulated forwarding paths and providing the determined reachability status and the one or more simulated forwarding paths to a user device associated with the reachability query which causes the user device to present the network configuration information for each simulated forwarding path.

Abstract: A system for simulating network configurations includes data processing hardware and memory hardware in communication with the data processing hardware. The memory hardware stores instructions that when executed on the data processing hardware cause the data processing hardware to perform operations. The operations includes receiving one or more parameter changes for a production network model of a network. The operations also include generating a simulation network model including the one or more parameter changes. Another operation includes analyzing the simulated network flow within the simulation network model. The operations also include generating a report including an impact of the parameter changes on the network. The operations may also include receiving a production network log including a recorded workflow for the production network model and simulating the production workflow of the production network log within the simulation network model to generate a simulated network log.

Abstract: A method of network reachability impact analysis includes receiving a plurality of network configuration snapshots for a network. The method also includes selecting a first network configuration snapshot of the network and a second network configuration snapshot of the network. The method further includes generating a first reachability graph representing packet reachability of the network for the first network configuration snapshot. The method also includes generating a second reachability graph representing packet reachability of the network for the second network configuration snapshot. The method also includes computing a reachability differentiation graph identifying a net change to reachability from the first reachability graph to the second reachability graph. The method further includes generating a reachability differentiation report including a human-interpretable output of the net change to reachability.
