A distributed computing system is configured to compute operational data for a video advertisement delivery system. Cloud-based resource are used to calculate operational parameters such as geographical data, unique advertisement delivery instances and segments of consumers that received the video advertisements.

Geo, segment, uniques distributed computing system

Techniques and systems for operating a video ad exchange includes controlling an ad server to receive ad requests from viewer devices, provide ad responses to viewer devices, generate an ad delivery data file that includes information about delivery of ads to the viewer devices, and transfer the ad delivery data file to a distributed computing cloud. The technique further includes controlling an ad data infrastructure mechanism to download the cloud-based ad delivery data file into a local memory, and process the copied ad delivery data file to generate billing data. An ad data infrastructure mechanism receives a configuration file from the ad server, verifies that all items in the configuration file from the ad server were used in the generation of the first billing data, and removes non-verifiable items from the first billing data to generate a final billing data.

Audited pipelined distributed system for video advertisement exchanges

A system is used to analyze the implementation of a protocol by a device-under-analysis (DUA). The system includes a source endpoint, a destination endpoint (the DUA), and a message generator. The source endpoint generates an original message and attempts to send it to the DUA. The original message is intercepted by the message generator, which generates a replacement message. The replacement message is then sent to the DUA instead of the original message. The replacement message is deliberately improper so as to analyze the DUA's implementation of the protocol. The message generator includes a structure recognition system and a mutation system. The structure recognition system determines the underlying structure and/or semantics of a message. After the structure recognition system has determined the structure, it creates a description of the structure (a structure description). The mutation system modifies the message based on the structure description to generate a replacement message.

Modification of messages for analyzing the security of communication protocols and channels

A security analysis methodology is used to analyze the security of a device-under-analysis (DUA) with respect to a particular protocol message exchange. First, the mutation points that exist in the message exchange are determined. Then, the message exchange is executed multiple times&#x2014;once for each mutation point. Each execution applies the mutation associated with that particular mutation point (e.g., a particular message during the exchange is modified in a particular way) to create a mutated message exchange. In other words, each message exchange with an applied mutation point corresponds to a test case.

Syntax-based security analysis using dynamically generated test cases

A system and method for analyzing and/or testing member devices in a multi-device system. The multi-device system includes a device-under-analysis (DUA) and a device-under-observation (DUO). An analyzer that is external to the multi-device system generates and sends test messages to the DUA. The analyzer monitors the health of the multi-device system through the DUO and detects a system-wide impact of the DUA caused by the test messages. The analyzer analyzes the DUA based on the test messages and the system-wide impact.
