Abstract: Systems, methods, and other embodiments associated with performing intrusion detection on load balanced network traffic are described. In one embodiment, a method includes receiving, at a load balancer host, an encrypted data packet from a remote computer. A certificate established between the remote computer and a destination service being accessed by the remote computer is used by the load balancer host to decrypt the encrypted data packet to create an unencrypted data packet. The unencrypted data packet is routed to an intrusion detection system at the load balancer host. The intrusion detection system is controlled to execute intrusion detection upon the unencrypted data packet. A secure connection is established with the destination computing node. The unencrypted data packet is re-encrypted and transmitted over the network using the secure connection to the destination computing node.

Abstract: Systems, methods, and other embodiments that interrupt multiple processors to process packets of a single flow are described. In one embodiment, a method includes maintaining a plurality of queues to hold interrupt requests created for packets received by a network device. Each queue is associated with a processor that will be interrupted by interrupt requests to process packets. The network device is configured to control how to queue interrupt requests created for a flow of packets. The network device is configured such that when a threshold number of interrupt requests created for the flow of packets have been inserted within a queue, subsequent interrupt requests created for subsequently received packets of the flow are inserted in a different queue. In this way, the network device is controlled to interrupt multiple processors for the flow of packets by queuing interrupt requests for the flow into different queues.

Abstract: In general, techniques are described by which to perform error concealment for audio data using reference pools. A device comprising a memory and a processor may perform the techniques. The memory may store a bitstream. The processor may obtain a reference pool of one or more reference audio frames, each of the one or more reference audio frames representative of a different portion of the audio data. The processor may determine that a current audio frame is unavailable, and obtain, responsive to determining that the current audio frame is unavailable and based on a successive audio frame to the current audio frame in a bitstream, a reference audio frame of the one or more reference audio frames. The processor may replace the current audio frame with the reference audio frame, and render the reference audio frame to one or more speaker feeds.

Abstract: Technologies are described herein for reducing network traffic when replicating memory data across hosts. The memory data stored in a main memory of the host computer is replicated to a main memory of a second host computer. Memory data from the local data storage of the second host computer that is a duplicate of memory data from the main memory is identified. Instead of sending the memory data from the main memory that is duplicated, the duplicated memory is copied from the local storage to the main memory of the second host computer.

Abstract: Technologies are described herein for examining memory data of execution environments to identify potential anomalies. An execution environment is identified as having a potential anomaly. The memory data associated with the execution environment is identified as having a potential anomaly. Checksums may be generated for the identified memory and for memory associated with other execution environments. Execution environments may be identified as having potential anomalies based, at least in part, on a commonality of the memory data of the execution environment that is identified as a having a potential anomaly with the memory data of another execution environment. Different actions may be performed on the execution environments that are identified as having a potential anomaly.

Abstract: A technology is described for identifying a destination physical host used to host a computing instance modeled on a source computing instance. An example method may include obtaining specifications for a source computing instance in preparation to migrate the source computing instance to a destination physical host. A destination physical host may then be identified for hosting a destination computing instance modeled on the source computing instance, where the destination physical host may have specifications determined to support the destination computing instance. A model of the source computing instance as hosted on the source physical host may be compared with a model of the source computing instance as hosted on the destination physical host to identify any conflicts that may prevent the destination physical host from hosting the destination computing instance.
