Abstract: A network orchestrator capable of selecting a primary virtual internet gateway (VIG) is provided. During operation, the network orchestrator can monitor roundtrip times for multiple packets between a primary VIG and a branch gateway, and between a secondary VIG and the branch gateway.

The network orchestrator can then select a new primary VIG based on the first and second forecast roundtrip times.

Abstract: Encrypted memory access using page table attributes is disclosed. One example is a memory system including a memory controller at a memory interface. The memory controller includes an encryptor to control a plurality of memory access keys respectively associated with memory regions, where each memory region is allocated to a respective client, and an access manager to receive an access request from a client, the access request including a client access key to access a memory element.

Based on the determination and a mode of operation, the access manager provides a response to the access request.

Abstract: Example embodiments disclosed herein relate to propagating belief information about malicious and benign nodes. In one example, a domain name system (DNS) resolution graph including multiple nodes is determined. In this example, a first subset of nodes is determined based on an initial benign value or an initial unknown value associated with the respective nodes. In the example, benign belief information is propagated for the first subset based on the respective initial benign values. Moreover, in the example, a second subset of the nodes is determined based on an initial malicious value or an initial unknown value. Malicious belief information is propagated for the second subset based on the respective malicious values. The propagated belief information is copied to a DNS resolution graph.
