Abstract: Methods and devices for logically segmenting an LSP so that OAM DTUs may be used to determine the performance and/or the status of LSP segments. To segment a previously determined LSP, a dedicated subpath (a logical LSP) within that predetermined LSP is defined between two LSRs that are capable of processing OAM DTUs. The source node (source LSR) establishes a logical LSP between itself and the destination node (destination LSR) using an LDP. In doing this, the logical LSP traverses a specific path and transits through specific nodes in that path. The source node then transmits an OAM DTU or any other specialized DTU to the destination node using a label specifically associated with the logical LSP that was established. The characteristic of the specific path traversed by the logical LSP can thus be determined by when, how, and if the specialized DTU is received by the destination node.

Abstract: Web services, such as UDDI based web services, are intended to operate synchronously, e.g., a client issues a discovery request for availability of a service provider, or the client issues a web service request for service by a discovered service provider, and the client is expected to block/wait until a response is received to the clients request. While this configuration may work effectively when the client has a stable network connection, it is not effective when the client is offline. An environment is disclosed for effectively implementing web services when the client is offline by faking appropriate registry and service provider responses, and then deferring request processing until network connectivity is restored.

Abstract: A server array controller that includes a Data Flow Segment (DFS) and at least one Control Segment (CS). The DFS includes the hardware-optimized portion of the controller, while the CS includes the software-optimized portions. The DFS performs most of the repetitive chores including statistics gathering and per-packet policy enforcement (e.g. packet switching). The DFS also performs tasks such as that of a router, a switch, or a routing switch. The CS determines the translation to be performed on each flow of packets, and thus performs high-level control functions and per-flow policy enforcement. Network address translation (NAT) is performed by the combined operation of the CS and DFS. The CS and DFS may be incorporated into one or more separate blocks. The CS and DFS are independently scalable. Additionally, the functionality of either the DFS or the CS may be separately implemented in software and/or hardware.

Abstract: Individual records of a data set include data and semantic information to describe the data. The records in the data set are encoded to generate an encoded data set using a compression function which is determined from semantic information that is common to multiple records of the data set. Multiple records of the encoded data set include the data without the common semantic information. The encoded data set is transmitted, or otherwise communicated, to a destination device along with an expansion function that includes the semantic information that is common to the multiple records of the data set. The destination device expands the encoded data set with the expansion function such that the multiple records of the encoded data set are expanded to include the common semantic information.

The first set of targets is published to the originator.

Abstract: A system and method for enabling highly scalable multi-node event distribution networks through the use of summary-based routing, particularly event distribution networks using a content-based publish/subscribe model to distribute information. By allowing event routers to use imprecise summaries of the subscriptions hosted by matcher nodes, an event router can eliminate itself as a bottleneck thus improving overall event distribution network throughput even though the use of imprecise summaries results in some false positive event traffic. False positive event traffic is reduced by using a filter set partitioning that provides for good subscription set locality at each matcher node, while at the same time avoiding overloading any one matcher node. Good subscription set locality is maintained by routing new subscriptions to a matcher node with a subscription summary that best covers the new subscription.

Abstract: A next generation performance network management system (30?) includes a first component (34a) that monitors one or more attributes of network elements (111–11n, 121–12m, 20 and 26) as well as peripheral devices (16 and 22) and interconnecting links (18, 24) to establish an historic trend for each monitored element. A second performance management system component (34b) monitors, on a near real-time basis, critical attributes of elements identified from historic trends as undergoing performance degradation. If such performance degradations persist, as detected by such near real-time monitoring, then the network operator can repair or replace the element in question to maintain network performance.
