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 translation: 多个虚拟局域网（VLAN）的以太网报警指示信号（ETH-AIS）信息被合并并分发到单个以太网帧中的多个VLAN。 注意，如本文所使用的，“报警指示信号（ETH-AIS）”是指IEEE 802.x或ITU-T Y.1731以太网报警指示信号。 接收具有综合ETH-AIS信息的以太网帧的设备通常将每个端口转发出帧，该端口传送合并的ETH-AIS信息中包含的一个VLAN的流量。

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: 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: 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.

Abstract: The present invention is suitable for use in a communications system that downloads applications over a broadcast file system (BFS). An application services interface (ASI) provides the BFS an application file including a configuration file and an image file that are stored in a service manager in set-tops. Additionally, the ASI provides the BFS a content file that is included in the application file. The provided content file is separated into service files, where each service file is associated with a particular service. When a set-top requests a service, the associated service file is subsequently loaded onto the set-top. Alternatively, a service file is stored in memory until such time as another service is requested, which at that point the older service file is removed from memory to allow space for the newly requested service file.

Abstract: An XML document can be represented in a compact binary form that maintains all of the features of XML data in a useable form. In response to a request for a modification (e.g., insert, delete or update a node) to an XML document that is stored in the compact binary form, a certain representation of the requested modification is computed for application directly to the binary form of the document. Thus, the requested modification is applied directly to the persistently stored binary form without constructing an object tree or materializing the XML document into a corresponding textual form. Taking into account the nature of the binary form in which the document is encoded, the bytes that actually require change are identified, including identifying where in the binary representation the corresponding actual changes need to be made.
