Abstract: In general, techniques are described that provide a modular software architecture for a route server within an Internet Exchange. The route server comprises an interface and a control unit. The interface receives a route advertisement advertising a route from one of the SP networks and defining attributes for the route. The control unit includes inbound, route and outbound processing modules to process the route advertisement. The inbound processing module updates the route advertisement to add an optional field that stores a copy of the attributes. The route processing module produces an outbound route advertisement that includes attributes of the Internet Exchange and, within the optional field, the original path attributes. The outbound processing module processes the outbound route advertisement to replace the attributes of the Internet Exchange with the original path attributes and outputs the outbound route advertisement to advertise the route to the SP networks.

Abstract: A network node for communicating data packets secured with a security protocol over a communications network includes a host information handling system (IHS) and one or more external security offload devices coupled by a secure data link. The host IHS communicates state information about data packets, and the external offload security device provides stateless secure data encapsulation and decapsulation of packets using a security protocol.

Encapsulation and decapsulation of packets by the external security offload device reduces network latency and reduces the computational load on the processor in the host IHS. Maintaining state information in the host IHS allows hot-swapping of external security offload devices without information loss.

Abstract: A server receives “registration” messages from nodes in a network, sufficiently infrequently to prevent overburden. Registration messages include information about registering nodes, other nodes, or node relationships. The server sends “instruction” messages to registering nodes, requesting information about the network. Each registering node obtains the requested information, and forwards those messages to other nodes, which act similarly. Nodes receiving instruction messages sometimes send “reporting” messages to the server, providing information it originally requested. The server thus receives detailed information about the network, without communicating with too many nodes, and without aggregating too much of that information. The server can interact with users using only resources growing at O(1) with the size of the network.

Resources are registered in and made accessible from multiple different namespaces. Resources are identified using nested queries that filter results at multiple levels of a hierarchical namespace.

Abstract: Methods, servers and systems for communicating signaling information in a telecommunications signaling network may involve using a topology tree categorizing network nodes into groups, receiving a first message encoding signaling information from a source, decoding the received first message into an internal representation of the message, determining if the internal representation identifies a destination component in the topology tree, performing application level routing operations by hierarchy to determine if information contained in the internal representation identifies a destination component in the topology tree, packaging the information contained in the internal representation into a second message encoding signaling information, and sending the second message encoding signaling information to the identified destination component.

Abstract: Techniques for performing network-assisted peer discovery to enable peer-to-peer (P2P) communication are described. In one design, a device registers with a network entity (e.g., a directory agent) so that the presence of the device and possibly other information about the device can be made known to the network entity. The network entity collects similar information from other devices. The device sends a request to the network entity, e.g., during or after registration. The request includes information used to match the device with other devices, e.g., information about service(s) provided by the device and/or service(s) requested by the device. The directory agent matches requests received from all devices, determines a match between the device and at least one other device, and sends a notification to perform peer discovery. The device performs peer discovery in response to receiving the notification from the network entity.

Abstract: XML parsing (PXP) can be improved using multicore CPUs, enhancing its suitability for scientific data. One approach is to divide the XML document into equal-sized chunks, and parse each chunk in parallel. XML parsing is inherently potentially dependent on all preceding characters. The skeleton, an outline of the document generated during a fast preparse, is used to guide full parallel parsing. The preparse is a sequential phase that limits scalability, and this phase can also be parallelized using a meta-DFA mechanism. For each state q of the original preparser the meta-DFA incorporates a complete copy of the preparser state machine as a sub-DFA which starts in state q running multiple instances of the preparser simultaneously when parsing a chunk, with each possible preparser state at the beginning of a chunk represented by an instance. By pursuing all possibilities simultaneously, the meta-DFA allows each chunk to be preparsed independently in parallel.

Port numbers are assigned to the firewall processing nodes within the cluster and are used to distinguish between traffic sent to the cluster. Each network connection is assigned a destination port number.
