Abstract: Evidence gathering and analysis from networked machines can be automated and made policy-based. In one embodiment, the present invention includes, a networked machine receiving an instruction from a server to execute a pre-recorded action sequence designed to capture evidence data. The machine can annotate the captured evidence data with meta-data, and send the annotated evidence data to the server. The server can then perform analysis on the collected evidence data and present the evidence data and the analysis to an administrator.

Abstract: Systems and methods for altering a latency of network messages. A latency control system is configured to alter the latency of one or more network messages transmitted in a network. The latency of the network messages may simulate a latency associated with a network connection. A message queue is controlled by the latency control system to implement the latency, which can be increased or decreased. The latency may be increased and/or decreased dynamically.

Abstract: A system and method for enabling a programmable device to execute instructions without interruption. An instruction space for storing instructions from a host application is bifurcated to define a program segment and a hold segment. At startup, instructions are loaded into the hold segment, and the programmable device begins executing those instructions. While the hold segment instructions are executed, the program segment is loaded with instructions. Once the program segment is filled, control is shifted to it and instructions from this segment are executed by the programmable device. When the program segment has been executed, control is shifted back to the hold segment, and instructions are taken from it while the program segment is reloaded with a fresh set of instructions from the host application. Once the program segment is reloaded, control is redirected and execution of instructions from the program segment is continued.

Abstract: The present invention provides for discovering diagnostic port functionality in a distributed system. A computer system requests network addresses for one or more chassis. A chassis receives the request for a network address and returns a corresponding network address at least for the chassis. The computer system receives one or more network addresses corresponding to the one or more chassis. The computer system requests resource data from each of the one or more corresponding network addresses. The chassis receives the request for resource data and returns resource data representing at least the current configuration of the chassis to the requesting computer system. The computer system receives resource data representing the configuration of the one or more chassis. The computer system presents the received resource data at the requesting computer system.
