摘要： A state detection circuit compares a target connection with an immediate previous connection based on an identifier of an incoming packet and detects a post-transitional state of the target connection based on a control flag of the incoming packet and on a pre-transitional state of the target connection detected just before if the target connection is identical with the immediate previous connection; and a connection counting circuit increments or decrements the number of target connections only when the detected post-transitional state indicates a start or end of the target connection.

摘要： A method includes generating quality of service requirement information which includes packet loss rate indication information. The packet loss rate indication information includes an acceptable maximum packet loss rate and a reference number of service data packets. The reference number of service data packets indicates a reference measurement number for counting the packet loss rate. The method also includes sending the quality of service requirement information.

摘要： A method and system for detecting anomalous network activity in a cloud-based compute environment. The method comprises receiving configuration data and network activity observations for a set of virtual entities in the cloud-based compute environment; creating a profile for each virtual entity in the set of virtual entities, when the virtual entity does not already have an associated profile; dynamically updating the virtual entity of a profile with the respective network activity observations of the virtual entity; and determining whether anomalies have been detected.

摘要： Embodiments disclosed include a method and apparatus for global traffic control and optimization for software-defined networks. In an embodiment, data traffic is optimized by distributing predefined metrics (data traffic information) to all controllers in the network. The predefined metrics are specific to local network switches and controllers, but are distributed to all peers at configurable intervals. “Local” as used herein implies one POP and its associated switch and controller. The method of distribution of local POP metrics is strictly in band using a packet as defined by the protocol used by the data network.

摘要： Method and system for capturing summaries of data flows in an electronic, packet-switched communication network, the method comprising: receiving, from a node of the communication network, packet flow data; obtaining a subset of the packet flow parameters (IP src, IP dst, port src, port dst, protocol), based on the packet flow data; obtaining a packet flow statistic, based on the packet flow data; updating a collection of stored packet flow summaries, based on a subset of the packet flow parameters and the packet flow statistic. The stored packet flow summaries are arranged as nodes in a tree data structure.

摘要： A method for creating a flow profile is provided. The method identifies a first plurality of flow measurements, each of which corresponding to one of a plurality of flows exchanged between a computing entity and a service during a first time period. The method, for each of a first plurality of buckets each of which has a pair of lower and upper bounds, increments a counter of the corresponding bucket for each of the plurality of flow measurements that falls within the pair of bounds of that bucket. The method generates a second plurality of buckets by merging and splitting at least some of the first plurality of buckets, identifies a second plurality of flow measurements for the computing entity during a second time period, and distributes these measurements into the second plurality of buckets. The method generate the flow profile by aggregating the first and second pluralities of buckets.

摘要： A system for managing web traffic comprising a meta control operating on a first processor having a first control interface and configured to generate a request for content and to transmit the request for content over a digital data network to a meta control server. The meta control server operating on a second processor and configured to receive the request for content and to select data for one or more second control interfaces as a function of data associated with the first control interface and to transmit the data for the one or more second control interfaces over the digital data network to the first control interface. The first control interface displays the data for the one or more second control interfaces and monitors user activity associated with the data.

摘要： Methods and apparatus to credit streaming activity using domain level bandwidth information are disclosed. An example apparatus includes a packet collector to collect data packets via a network interface, and a traffic analyzer to determine domain data of the data packets and associate bandwidth usage values with the domain data to define bandwidth usage data by domain. The apparatus also includes a bandwidth usage data storage to store the associated bandwidth usage data by domain.

摘要： A method for selectively processing a packet flow using a flow inspection engine is disclosed. The method includes receiving, by at least one hardware data plane processor component in a network packet broker, a plurality of packets associated with a packet flow, and forwarding, by the at least one hardware data plane processor component to at least one flow inspection engine, a copy of at least a portion of one or more of the initial packets of the packet flow. The method further includes providing, by the at least one hardware data plane processor component to the at least one flow inspection engine, packet flow statistical data resulting from a high throughput processing of the plurality of packets by the at least one hardware data plane processor component and generating, by the at least one flow inspection engine, metadata records using the copy at least a portion of the of the one or more of the initial packets and the packet flow statistical data, wherein the at least one hardware data plane processor component generates the statistical data from the plurality of packets independent of any instruction from the at least one flow inspection engine.

摘要： A programmable switch includes ports, and circuitry to receive cache messages for a distributed cache from client devices. The cache messages are queued for sending to memory devices from the ports. Queue occupancy information is generated and sent to a controller that determines, based at least in part on the queue occupancy information, at least one of a cache message transmission rate for a client device, and one or more weights for the queues used by the programmable switch. In another aspect, the programmable switch extracts cache request information from a cache message. The cache request information indicates a cache usage and is sent to the controller, which determines, based at least in part on the extracted cache request information, at least one of a cache message transmission rate for a client device, and one or more weights for queues used in determining an order for sending cache messages.
