The techniques described herein describe diffusing packets through multipath inter-data center networks to identify faulty network apparatuses therein. In an implementation, a method of diffusing packets through a multipath inter-data center network to identify a faulty network apparatus in a source data center is disclosed. The method includes diffusing packets through various paths of a network fabric. Diffusing the packets includes sending out bursts of packets with varying packet header parameters to a set of machines in one or more target data centers. The method further include monitoring packet drops from the bursts of packets, issuing tracerts for each of the packet drops to identify corresponding failed routes, and triangulating the failed routes to identify the faulty network apparatus.

Various embodiments of the present technology generally relate to systems and methods for intelligent load shedding. More specifically, various embodiments of the present technology generally relate to intelligent load shedding of traffic based on current load state of target capacity. In some embodiments, a domain name resolution request to translate a domain name into an Internet protocol (IP) address can be received at DNS server. A status of each of multiple scaling units mapped to the domain name can be determined. A set of IP addresses (e.g., four IP addresses) corresponding to a subset of the multiple scaling units closest to the requesting device with statuses indicating availability for new traffic can be identified. Then, the set of IP addresses can be sent to the requesting device. The requesting device can the select which IP address to use (e.g., randomly) to route the traffic.

A distributed system for distributing conferencing data such as video, audio, and other conference data. The distributed system includes a conference data dispatch system, multiple conference participant computing systems, and a network distribution path through which conference data may be distributed from the conference data dispatch system to the various conference participant computing systems. The conference data is segmented. Each segment is encoded to be suitable to a particular class of participant computing systems. The encoded segments may be cached in an intermediary computing system to thereby avoid a strict unicast model for distributing conference data.

Adaptive streaming of conference media and data

Systems and methods are disclosed that facilitate transforming business and encoding rules defined in a persistent and relational format into XML schemas that provide a message format and validation logic for the message. A message can be received in delimited flat-file format and parsed to facilitate generating a value-added XML schema that represents both encoding rules and business rules associated with the message. The systems and methodologies detailed herein can be employed, for example, in applications utilized in a healthcare provider space and can be consistent with Health Level 7 standards to improve message validation and/or processing.

In a network multimedia conference, a bridge service that functions as a proxy for a client to join the conference dynamically selects a video stream from multiple video streams originating from the other participants of the conference and sends the selected video stream to the client for viewing. The bridge service monitors conferencing events of each participant and updates conferencing activity state variables of the participant, such as whether the participant is being shown to the client, whether the participant is talking, how long the participant has been shown or not shown, etc. Periodically, a weight assigned to each of the participants is computed based on the state variables, and the video stream of the participant with the highest weight is then selected for viewing by the client.

Systems and methods are disclosed that facilitate formally describing structured documents and complex validation rules associated therewith using value-added XSD schemas (VAXs). In accordance with aspects of the invention, structured documents can be translated, parsed, validated, and acknowledged in a single pass via utilization of XSD schema representations that capture complex data and business rules related to validation as a translation specification to convert delimited flat-file and/or structured documents to an XML format while providing ambiguity resolution and acknowledgements.

Single-pass translation of flat-file documents into XML format including validation, ambiguity resolution, and acknowledgement generation

Systems and methods are disclosed that facilitate formally describing structured documents and complex validation rules associated therewith using value-added XSD schemas (VAXs). Native XSDs can be utilized and annotated to generate VAXs that represent both the structure of a document and the complex validation rules used to validate the documents. VAXs can be annotated with declarative validation rules that can be assessed at run time to facilitate document validation. Additionally, VAXs can be annotated with validation handlers that comprise a predefined library of validation routines that can be called at run time to facilitate document validation.

A mechanism for validating a message, such as an XML message or other hierarchically-organized content. A validation engine walks through the tree represented by the message preferably in depth-first traversal order. Upon encountering each node in the tree, the validation engine consults a validation table to identify a delegate that is to be invoked. The validation engine then invokes the delegate identified for that node, and calls itself recursively on the subtrees of the current node. After the subtrees have been processed, the validation engine again consults the validation table to identify a post-handler for the current node, and then invokes the post-handler. An entry in the validation table may be flagged as 'exclusive' to prevent traversal of subtrees of the node corresponding to that entry. Additionally, there may be both global and local validation tables, where the global table is used when a node has no entry in the local table.
