    摘要： The disclosed data stream optimization process is containing two logical entities, the first being the pre-comparison optimizer component and the second being the comparison component. The pre-comparison optimizer component performs two discrete tasks. First, the input data stream is written into a next state buffer. Second, the elimination of redundancies involves detecting and removing redundant screen attributes, since the terminal's execution time for processing a screen attribute is more than that required for a data character. The comparison component contains three distinct sub-components. First, non-data constructs such as commands and orders are optimized and placed in the outgoing data stream. Second, the screen image that is represented by the data stream is compared to the existing screen image to further reduce the outgoing data stream. This reduced version is further reduced when repeated characters and fields are replaced with repeat orders which take up less space within the outgoing data stream. Lastly, the reduced outgoing data stream is operated on by a post-optimizer sub-component. The post-optimizer sub-component will first determine whether repeated characters existing at the end of the outgoing data stream can be replaced a single repeat order. Then, the sub-component proceeds to remove any unnecessary cursor control orders. Upon completion, the fully optimized data stream is routed to the terminal or conversion facility.

    摘要： Methods, apparatus, and computer program products for variable dynamic throttling of network traffic for intrusion prevention are disclosed that include initializing, as throttling parameters, a predefined time interval, a packet count, a packet count threshold, a throttle rate, a keepers count, and a discards count; starting a timer, the timer remaining on no longer than the predefined time interval; maintaining, while the timer is on, statistics including the packet count, the keepers count, and the discards count; for each data communications packet received by the network host, determining, in dependence upon the statistics and the throttle rate, whether to discard the packet and determining whether the packet count exceeds the packet count threshold; and if the packet count exceeds the packet count threshold: resetting the statistics, incrementing the throttle rate, and restarting the timer.
