Embodiments of the invention provide a method for determining errors and metrics in a computer network. The method includes positioning an analyzer in communication with the network, capturing a data trace of the network with the analyzer, determining a network device topology from a first processing of the data trace, building user layer protocols using a second processing of the data trace and the determined device topology, determining errors in the network device topology using protocol experts applied to the user layer protocols in conjunction with the determined device topology, and displaying at least one of the device topology and the determined errors to a user.
A method to analyze impact of changes to a model includes accessing a proposed change to a model. An expression that is relevant to the proposed change is accessed. An instances set associated the expression is obtained. The instance set is evaluated to determine an impact of the proposed change to the model. An application utilizes the expression of a model. An impact analyzer assesses impact of a change to the model by evaluating at least one of the one or more expressions and returning an evaluation set for use by the application.
According to one embodiment, a system is disclosed. The system includes an initiator device to transmit input/output (I/O) write data and a target device, coupled to the initiator device, to receive the write data from the initiator device as a first segment of data and a second segment of data. The target device re-transmits a transfer ready frame to force the initiator device to retransmit the second segment in response to detecting an uncorrectable error in the second segment.
