Filed:

Sep 15, 2003

Appl. No.:

10/663482

Inventors:

Stacy Prowell - Knoxville TN, US

International Classification:

G06F007/60

US Classification:

708200000

Abstract:

Hierarchical analysis of Markov chain usage models is provided. In some embodiments elements of an expanded matrix are calculated as a function of parent elements and child elements, rather than by direct inversion techniques. The expanded matrix is a first moment matrix of a flattened model. In hierarchical models, the flattened model represents a child model instantiated within a parent model. The child elements are elements of a child matrix, which is a first moment matrix of the child model. The parent elements are elements of a parent matrix, which is a first moment matrix of the parent model.

Abstract:

A system and method includes an operational network that communicates with an external network by opening a first transmission protocol socket. A data diode coupled to the operational network and a gateway enables the one-way transfer of all information received from the external network and transmitted by the operational network to the gateway such that no information travels from the gateway to the operational network or the external network. The gateway opens a second transmission protocol socket by mapping a sequence number to an acknowledgement number and increasing that mapped acknowledgement number by a value of one. A transmitter then transmits the acknowledgment to a remote network or a gateway.
