US11252189B2	Abuse mailbox for facilitating discovery, investigation, and analysis of email-based threats Introduced here are computer programs and computer-implemented techniques for discovering malicious emails and then remediating the threat posed by those malicious emails in an automated manner. A threat detection platform may monitor a mailbox to which employees of an enterprise are able to forward emails deemed to be suspicious for analysis. This mailbox may be referred to as an “abuse mailbox” or “phishing mailbox.” The threat detection platform can examine emails contained in the abuse mailbox and then determine whether any of those emails represent threats to the security of the enterprise. For example, the threat detection platform may classify each email contained in the abuse mailbox as being malicious or non-malicious. Thereafter, the threat detection platform may determine what remediation actions, if any, are appropriate for addressing the threat posed by those emails determined to be malicious.

US11249784B2	Specifying service chains Some embodiments provide novel methods for performing services for machines operating in one or more datacenters. For instance, for a group of related guest machines (e.g., a group of tenant machines), some embodiments define two different forwarding planes: (1) a guest forwarding plane and (2) a service forwarding plane. The guest forwarding plane connects to the machines in the group and performs L2 and/or L3 forwarding for these machines.

US11249536B2	Reducing power consumption of communication interfaces by clock frequency scaling and adaptive interleaving of polling Reducing power consumption of communication interfaces by clock frequency scaling and adaptive interleaving of polling is disclosed. In a first aspect, a control system controls transmission of a command via a serial interface at a higher clock frequency. After transmission, the control system and the interface are operated at a lower clock frequency to save power during command execution. In this aspect, a reduction in polling corresponds to the reduction in clock signal frequency. When the command is complete, the interface is operated at the higher frequency to send another command. In a second aspect, after the control system sends a command to the receiving device, polling is suspended and an execution time of the command is tracked. Polling begins when the tracked execution time almost equals an expected completion time. Both aspects disclosed above may be implemented to reduce power consumption in exchange for a small increase in latency.
