Abstract: Network traffic is monitored and an optimal framing heuristic is automatically determined and applied. Framing heuristics specify different rules for framing network traffic. While a framing heuristic is applied to the network traffic, alternative framing heuristics are speculatively evaluated for the network traffic. The results of these evaluations are used to rank the framing heuristics. The framing heuristic with the best rank is selected for framing subsequent network traffic. Each client/server traffic flow may have a separate framing heuristic. The framing heuristics may be deterministic based on byte count and/or time or based on traffic characteristics that indicate a plausible point for framing to occur. The choice of available framing heuristics may be determined partly by manual configuration, which specifies which framing heuristics are available, and partly by automatic processes, which determine the best framing heuristic to apply to the current network traffic from the set of available framing heuristics.

Abstract: In a multi-processor system, an executable software image including an image header and a segmented data image is scatter loaded from a first processor to a second processor. The image header contains the target locations for the data image segments to be scatter loaded into memory of the second processor. Once the image header has been processed, the data segments may be directly loaded into the memory of the second processor without further CPU involvement from the second processor.

Abstract: A hypervisor receives an interrupt that includes a target address and, in turn, branches to an administrating interrupt vector. Next, the administrating interrupt vector determines whether to branch to a piggyback interrupt handler corresponding to a piggyback interrupt vector. Based upon the determination, the hypervisor either branches to the piggyback interrupt handler or to an administrating interrupt handler that corresponds to the administrating interrupt vector.

Abstract: Ethernet Alarm Indication Signal (ETH-AIS) information for multiple Virtual Local Area Networks (VLANs) is consolidated and distributed to the multiple VLANs in a single Ethernet frame. Note, as used herein, “Alarm Indication Signal (ETH-AIS)” refers to an IEEE 802.x or ITU-T Y.1731 Ethernet Alarm Indication Signal. A device receiving the Ethernet frame with the consolidated ETH-AIS information typically forwards the frame out each port that communicates traffic for one of the VLANs included in the consolidated ETH-AIS information.

Abstract: A network analysis system invokes an application specific, or source-destination specific, path discovery process. The application specific path discovery process determines the path(s) used by the application, collects performance data from the nodes along the path, and communicates this performance data to the network analysis system for subsequent performance analysis. The system may also maintain a database of prior network configurations to facilitate the identification of nodes that are off the path that may affect the current performance of the application. The system may also be specifically controlled so as to identify the path between any pair of specified nodes, and to optionally collect performance data associated with the path.

Abstract: Techniques are provided for incrementally maintaining an XML index built to access XML data that is encoded in binary XML form. Rather than delete and reinsert index entries of all the nodes of a modified XML document, only the index entries of the affected nodes are modified. Consequently, the order key values stored in the index may become inconsistent with the current hierarchical locations of the nodes to which the order key values correspond. Techniques are described for resolving the inconsistencies, and for addressing additional problems that result when the XML index is path-subsetted.

Abstract: A routing validation method and system identifies routers that are likely to be the cause of differences in forwarding tables associated with two versions of a network. Each destination sub-network prefix is processed to identify all the routers that exhibit differences in their forwarding table for this prefix. Each router exhibiting a difference is assessed to determine whether the difference may have been propagated to this router from another router. If the difference could not have been propagated from another router, this router is identified as a potential source of the observed difference. By eliminating routers that could have received the effects of the differences from another router, the task of identifying the root cause of the observed differences is substantially reduced in complexity.
