Latest Patents

One of Poelstra's latest patents is titled "System and method for network traffic and I/O transaction monitoring of a high speed communications network." This innovative architecture enables performance detection and diagnostics in storage area networks and other types of networks. The system employs a three-tiered distributed computing architecture, which includes a data source tier, a portal tier, and a client tier. The data source tier utilizes multiple data collection sources, or data probes, to monitor physical data on the network medium. These probes analyze network data and generate metrics that describe various attributes of the network data. The metrics are synchronized in time through time stamps associated with the monitored data. The portal tier encapsulates these metrics into data containers, which can be accessed by the client tier. The client tier provides a user interface for displaying diverse types of network information derived from the data containers.

Another significant patent by Poelstra is the "Network tap with interchangeable ports." This invention allows attached devices, such as intrusion detection systems, to transmit information into a communication line of the network without disrupting the existing network traffic. When the attached device is an intrusion detection device, the network tap connects to a firewall. The design incorporates an Ethernet switch or field programmable gate array (FPGA) to coordinate the transmission of device data, preventing data collisions. The network tap can operate in various modes to accommodate different capabilities of attached devices and features multiple port configurations for user convenience.
