Abstract: Simulating latency in a network environment. A first device receives a latency request. The first device sends a latency support confirmation. The first device receives an I/O frame. The I/O frame comprising a latency simulating bit and a latency duration. Based on the latency simulating bit and the latency duration, holding, by the first device, the I/O frame. The first device sends the I/O frame on.

Abstract: Simulating latency in a network environment. A device sends a latency request. The device receives a latency support confirmation. The device builds an I/O frame. The I/O frame comprises a latency simulating bit and a latency duration. Based on the latency simulating bit and the latency duration, the device holds the I/O frame. The device sends the I/O frame.

Abstract: Embodiments of the invention provide a method and corresponding computing device for testing network adapters. The computing device receives a network address for the network. The computing device identifies a device based on the network address, the device having a network adapter. Then the computing device identifies additional devices along a route to the device, each of the additional devices having a respective network adapter. The computing device sends one or more requests to each the network adapters. The computing device determines an indication of reliability of each of the network adapters based on handling of the requests by the network adapter. A network adapter may also maintain logic to test itself in another embodiment.
