DIAGNOSIS OF A NETWORK ADAPTER DURING NETWORK OPERATION

摘要

An adapter is configured to connect to a network. The adapter including a controller configured to receive a stream of network communication from a computer system physically connected to the adapter. The controller is further configured to detect a first identifier. The first identifier is related to a first communication unit of the stream of network communication. In response to detecting the first identifier, the controller is further configured to direct the first communication unit away from the network and back toward the controller through a loopback pathway. The controller is further configured to direct the stream of network communication away from the computer system and to the network.

1. A method of testing a network adapter, the method comprising:
receiving, via a system connector physically connecting a computer system to the network adapter, a stream of network communication from the computer system, the stream of network communication containing a first packet encoded with a loopback identifier; detecting, by the network adapter, the loopback identifier of the first packet; directing, from an output of a chip on the network adapter and in response to the detecting the loopback identifier, the first packet to an input of the chip on the network adapter; transmitting, from the output of the chip, the stream of network communication to a network; receiving, from the input of the chip, the first packet; and transmitting, via the system connector, the first packet from the network adapter back to the computer system.
