摘要： A route control architecture allows a network operator to flexibly control routing between the traffic ingresses and egresses in a computer network, without modifying existing routers. An intelligent route service control point (IRSCP) replaces distributed BGP decision processes of conventional network routers with a route computation that is flexible and logically centralized but physically distributed. One embodiment supplements the traditional BGP decision process with a ranking decision process that allows route-control applications to explicitly rank traffic egresses on a per-destination, per-router basis. A straightforward set of correctness requirements prevents routing anomalies in implementations that are scalable and fault-tolerant.

摘要： An aspect of the disclosed technology is a general-purpose platform that may be used to provide resilient cloud services. Tasks may be written as procedures in general-purpose programming languages that directly manipulate resources via control interfaces. In one implementation, resource states, such as router configurations and virtual machine states, associated with a cloud customer that provides communications services, may be abstracted into tables in a relational or semi-structured database. State changes that have been written to the database tables are automatically propagated by the database to appropriate customer physical devices, such as network elements, thereby implementing various customer network operations.

摘要： A method includes instantiating a cloned network that includes a second set of virtual service nodes. The second set of virtual service nodes includes at least one cloned virtual service node that is a clone of a corresponding virtual service node in a first set of virtual service nodes. The at least one cloned virtual service node has access to a history of events that occurred at the corresponding virtual service node in the first set of virtual service nodes. The method includes initiating an interactive debugging session that includes step by step processing of the events of the history of events.

摘要： Methods and apparatus to debug a network application are described. A described example network includes a live control network to collect control messages to create a history of network states, the history of network states reflecting an order in which control messages are processed, the live control network to roll back from a current state to a past state upon detection of an improper sequence of messages and to process the messages in a corrected sequence, the corrected sequence to be stored in the history. The described example network further includes a virtualized network corresponding to the live control network, the virtualized network responsive to a command from an operator to step through the history to facilitate debugging.

摘要： A multi-staged framework for detecting and diagnosing Denial of Service attacks is disclosed in which a low-cost anomaly detection mechanism is first used to collect coarse data, such as may be obtained from Simple Network Management Protocol (SNMP) data flows. Such data is analyzed to detect volume anomalies that could possibly be indicative of a DDoS attack. If such an anomaly is suspected, incident reports are then generated and used to trigger the collection and analysis of fine grained data, such as that available in Netflow data flows. Both types of collection and analysis are illustratively conducted at edge routers within the service provider network that interface customers and customer networks to the service provider. Once records of the more detailed information have been retrieved, they are examined to determine whether the anomaly represents a distributed denial of service attack, at which point an alarm is generated.
