    Abstract: Techniques are disclosed for implementing direct memory access in a virtualized computing environment. A memory access policy of the virtualized computing environment is applied to a direct memory access connection request received from a first virtual machine via an exception path. The request is flagged to indicate that the request has been processed and the request is forwarded to a network interface device configured to execute offloaded network functions for one or more virtual machines. A memory access policy of the virtualized computing environment is applied to a direct memory access connection reply received from a second virtual machine on the exception path. The reply is flagged to indicate that the reply has been processed and the reply is forwarded to the network interface device. A direct memory access connection is established between first and second virtual machines in accordance with the request.

    Abstract: A route anomaly detection and remediation system analyzes a prefix for each route received to validate the route. A route monitoring component provides a centralized querying system for all routers from all devices to study routing history. A route collection component receives and stores all routes from multiple routers at a server. A set of microservice analysis components performs prefix analysis on each received route. Each microservice analysis component analyzes one or more portions of the prefix for each route to detect hijacked routes, leaked routes, withdrawn routes and/or other unhealthy routes before the routes are utilized for routing traffic on the network. The analysis performs new prefix validation and identifies healthy routes. Alerts identifying invalid routes are transmitted to an incident management system. Healthy routes are approved for usage by routers on the network to prevent network outages while improving network reliability, availability and stability.
