Patent number: 11533830Abstract: A cooling arrangement for an electronic device comprises a primary cooling device and a secondary cooling device. The primary cooling device includes a fluidic input line receiving a cooling fluid from a cooling fluid source and a fluidic output line returning the cooling fluid toward a drain. The primary cooling device is thermally connected to the electronic device, receives the cooling fluid from the fluidic input line and transfers heat from the electronic device to the cooling fluid before returning the cooling fluid via the fluidic output line. A flow detection device monitors a flow of the cooling fluid in the primary cooling device. The secondary cooling device is thermally connected to the electronic device. A processor activates the secondary cooling device to absorb and dissipate heat from the electronic device when the flow detection device detects a lack of flow of the cooling fluid in the primary cooling device.Type: GrantFiled: February 7, 2020Date of Patent: December 20, 2022Assignee: OVHInventors: Christophe Maurice Thibaut, Patrick-Gilles Maillot, Henryk Klaba

Patent number: 11530938Abstract: A flow detection device comprises a fluidic input port connected to a fluidic output port via a channel and a float located within the channel. A specific weight of the float exceeds a specific weight of a fluid injected in the flow detection device. Respective locations of the fluidic input port, of the channel and of the fluidic output port on the flow detection device cause the float to rise within the channel when a sufficient flow of the fluid is injected in the flow detection device. A sensor is provided to detect a position of the float within the channel. The flow detection device may be integrated in a cooling circuit having a cooling device for an electronic device to detect an eventual lack of a flow of a cooling fluid in the cooling circuit. A status of the flow of the cooling fluid is reported to a processor.Type: GrantFiled: February 6, 2020Date of Patent: December 20, 2022Assignee: OVHInventors: Christophe Maurice Thibaut, Patrick-Gilles Maillot, Henryk Klaba

Patent number: 11528295Abstract: Methods and systems for defending an infrastructure against a distributed denial of service (DDoS) attack use a software decoy installed in the infrastructure to deliberately attract a malware. An address or a domain name of a command and control (C&C) server is extracted from the malware. A client of the infrastructure uses the address or the domain name of the C&C server to connect to the C&C server. The client receives a command intended by the C&C server to cause the client to participate in the DDoS attack. The client forwards particulars of the DDoS attack to a cleaning component. The cleaning component discards incoming signals having one or more of the particulars of the DDoS attack. The address or domain name of the C&C server may be obfuscated in the malware, in which case reverse engineering is used to decipher the malware.Type: GrantFiled: June 14, 2019Date of Patent: December 13, 2022Assignee: OVHInventor: Sebastien Meriot

Patent number: 11528288Abstract: Methods allow a predicting and detecting potential anomalies at a service infrastructure. A strings table having entries that define character strings and corresponding anomaly probabilities is accessed. A log entry related to an event occurring in the service infrastructure is generated in a database. The log entry includes a character string designating a name of a file or an IP address and a domain name hosted by the service infrastructure. A search is made for the character string in the strings table. The domain name is marked as suspect if the character string is found in the strings table and if an anomaly probability for the character string exceeds a predetermined threshold. The anomaly probabilities may be calculated using a Bayesian filter that accounts for a number of domains hosted by the service infrastructure on which the character string has recently appeared.Type: GrantFiled: November 21, 2019Date of Patent: December 13, 2022Assignee: OVHInventor: Olivier Nicol

Patent number: 11422595Abstract: A health of a server infrastructure is supervised by sending measurement requests, from a polling node to a server of the server infrastructure, at each of successive polling periods. Measurements received from the server in response to the measurement requests are stored in a database. A machine learning system is trained using accumulated measurements stored in the database to construct a prediction model for the server. Compliance of a latest measurement received from the server with the prediction model for the server is evaluated. A corrective action is taken if the latest measurement does not comply with the prediction model for the server. Measurements received from a group of servers may be aggregated and the machine learning system may construct a prediction model for the group of servers. Compliance to the prediction model may be evaluated for the group of servers.Type: GrantFiled: April 27, 2020Date of Patent: August 23, 2022Assignee: OVHInventors: Morvan Le Goff, Raphael Glon, Sylvain Chenot, Alexis Autret

Patent number: 11411986Abstract: A data packet received at a service infrastructure is screened by a data packet cleaning system that successively applies each signature of a set of signatures as a mask to a predetermined area of a content of the data packet. If there is a byte-for-byte match between the predetermined area of the content and one of the signatures, an action corresponding to the matched signature is taken. The action is selected from unconditionally forwarding the data packet toward a server of the service infrastructure, unconditionally discarding the data packet, forwarding the data packet toward the server of the service infrastructure if a current flow of data packets being forwarded to the server is less than a flow threshold, and discarding the data packet if the current flow of data packets being forwarded to the server meets or exceeds the flow threshold.Type: GrantFiled: November 5, 2019Date of Patent: August 9, 2022Assignee: OVHInventor: Aurelien Dudouit
