Patent number: 11563641Abstract: A traffic shifting system is described to shift traffic away from one or more network devices or interfaces. The system ensures that traffic can be safely shifted off of a network device before the shifting occurs. The method is described as broken into several phases, such as a discovery phase, a pre-check phase, a shifting phase, and a post-shift phase. Before shifting occurs, the discovery phase is used to obtain network topology and configuration information. In the pre-check phase, that information is interrogated so that a shifting can be performed without negatively impacting the network. If the pre-check phase is passed, then the network shifting can occur through adjustment of configuration parameters, such as a cost parameter associated with an interface on any devices for which traffic is being shifted. Finally, in the post-shift phase, checks are performed to ensure traffic is shifting away from the network device.Type: GrantFiled: December 20, 2018Date of Patent: January 24, 2023Assignee: Amazon Technologies, Inc.Inventors: Dzianis Lisouski, Michal Zygmunt Zawirski, Robert Kennedy, Karl Andre McCabe, Paul A.

Patent number: 10411972Abstract: Generally described, systems and methods are provided for detecting the impact of network failures. The system collects performance information from a plurality of nodes and links in a network, aggregates the collected performance information across paths in the network, processes the aggregated performance information for detecting failures on the paths, adjusts the set of performance information by removing the performance information for any nodes considered to be associated with performance information that is statistically different from performance information from other nodes at a given location or extrapolates the collected information to other paths, and determines the impact to customers of the network failures detected using the adjusted set of performance information.Type: GrantFiled: August 4, 2017Date of Patent: September 10, 2019Assignee: Amazon Technologies, Inc.Inventors: Karl Andre McCabe, Eoin Francis Cavanagh, Sonali Roy, Carlos Vara Callau, Tyson James Lamoreaux, Alan Michael Judge, Timothy Richard Kohn

Patent number: 10243785Abstract: Technologies are provided for active monitoring of network fabrics, such as border network fabrics. For example, test packets can be generated and sent to destination devices within the network fabrics. The test packets can have destination ports that have been identified as closed destination ports. The success of the test packets can be determined based on whether ICMP error packet responses are received. If a network problem is detected based on results of the test packets, then traceroute packets can be used to identify the location of the network problem.Type: GrantFiled: June 14, 2016Date of Patent: March 26, 2019Assignee: Amazon Technologies, Inc.Inventors: John Corrigan, Karl Andre McCabe, Eoin Francis Cavanagh

Patent number: 10129089Abstract: A traffic shifting system is described to shift traffic away from one or more network devices or interfaces on those devices. The system ensures that traffic can be safely shifted off of a network device before the shifting occurs. The method is described as broken into several phases for simplicity, such as a discovery phase, a pre-check phase, a shifting phase, and a post-shift phase. Before shifting occurs, the discovery phase is used to obtain network topology and configuration information. In the pre-check phase, that information is interrogated so that a shifting can be performed without negatively impacting the network. If the pre-check phase is passed, then the network shifting can occur through adjustment of configuration parameters, such as a cost parameter. Finally, in the post-shift phase, checks are performed to ensure traffic is shifting away from the network device.Type: GrantFiled: December 22, 2015Date of Patent: November 13, 2018Assignee: Amazon Technologies, Inc.Inventors: Dzianis Lisouski, Michal Zygmunt Zawirski, Robert Kennedy, Karl Andre McCabe, Paul A.

Patent number: 9130976Abstract: Techniques described and suggested herein include systems and methods for identifying potential sources of infections of devices by unauthorized code. In an embodiment, network traffic is logged. A plurality of computing devices that include unauthorized code is identified. The logged traffic is used to identify information sources accessed by the identified affected devices. The identified information sources may be refined. Refinement of the identified information sources may include excluding information sources that have been accessed by uninfected devices. A user interface that allows a user to further refine the identified information sources may be provided.Type: GrantFiled: November 19, 2013Date of Patent: September 8, 2015Assignee: Amazon Technologies, INC.Inventors: Karl Andre McCabe, Jon Arron McClintock, David James Roy Erdmann
