摘要： An example method includes detecting, using sensors, packets throughout a datacenter. The sensors can then send packet logs to various collectors which can then identify and summarize data flows in the datacenter. The collectors can then send flow logs to an analytics module which can identify the status of the datacenter and detect an attack.

摘要： An example method can include monitoring a network to identify flows between nodes in the network. Once flows have been identified, the flows can be tagged and labelled according to the type of traffic they represent. If a flow represents malicious or otherwise undesirable traffic, it can be tagged accordingly. A request can then be made for a reputation score of an entity which can identify one or more nodes of the network.

摘要： In one embodiment, a monitoring device (or module) monitors messages exchanged between nodes in a communication network. The monitoring device further determines, based on time stamp data associated with each message, one or more latency distributions of paired response times between the nodes, and determines a node topology consistent with each of the one or more latency distributions of paired response times between the nodes. In some embodiments, the monitoring device also generates a graph of the node topology showing one or more communication links between the nodes, and annotates each communication link of the one or more communication links with at least one of a mean response time or a median response time based on at least one of the latency distributions.

摘要： The present technology is directed to mapping flow data and overlaying it on a geographic map. Furthermore the geographical map can also display attacks and the flow of an attack from the source to a logical entity. The map additionally can be accompanied with a pie chart relating to the attacks and intensity of attacks. Normal flows can also be displayed on the map along with the attack flows.

摘要： Systems, methods, and computer-readable media are provided for de-duplicating sensed data packets in a network. As data packets of a particular network flow move through the network, the data packets can be sensed and reported by various sensors across the network. An optimal sensor of the network can be determined based upon data packets reported by the various sensors. Data packets sensed and reported by the optimal sensor can be preserved for network analysis. Duplicative data packets of the particular network flow sensed and reported by other sensors of the network can be discarded to save storage capacity and processing power of network-flow analysis tools. Analysis of the particular network flow can be performed based upon the data packets sensed by the optimal sensor and non-duplicative data packets of the particular network-flow sensed by other sensors of the network.

摘要： The technology visualizes data flows within a datacenter in an interactive hierarchical network chord diagram. Based on analyzed data describing data flows, a portion of the data flows that originate at the same first endpoint and terminate at the same second endpoint can be grouped. Subsequently, the dataflow monitoring system displays an interactive hierarchical network chord diagram to include a chord with a first endpoint and a second endpoint. The chord represents the grouped portion of data flows that originate at the same first endpoint and terminate at the same second endpoint. Upon receiving a selection of the chord or the first endpoint of the chord, the dataflow monitoring system expands the grouped portion of the data flows into a more granular representation of the network.
