Abstract: According to an example, a method for bandwidth guarantee and work conservation includes determining virtual machine (VM) bandwidth guarantees assigned to VMs in a network including a source VM that communicates with destination VMs. The method further includes assigning minimum bandwidth guarantees to communications between the source VM with the destination VMs by dividing a VM bandwidth guarantee assigned to the source VM between the destination VMs based on active VM-to-VM communications between the source VM and the destination VMs. The method also includes allocating, by a processor, spare bandwidth capacity in the network to a communication between the source VM and a destination VM based on the assigned minimum bandwidth guarantees.

Abstract: Example embodiments relate to selective invalidation of packet filtering cache results based on rule priority. In example embodiments, a network node determines whether a rule identifier included in a cache entry of a cache of results of a packet filtering rule set is of a higher priority than a highest priority rule corresponding to a rule set version identifier included in the cache entry. If so, the network node may apply an action included in the cache entry.

Abstract: Illustrated is a system and method for identifying a memory page that is accessible via a common physical address, the common physical address simultaneously accessed by a hypervisor remapping the physical address to a machine address, and the physical address used as part of a DMA operation generated by an I/O device that is programmed by a VM. It also includes transmitting data associated with the memory page as part of a memory disaggregation regime, the memory disaggregation regime to include an allocation of an additional memory page, on a remote memory device, to which the data will be written. It further includes updating a P2M translation table associated with the hypervisor, and an IOMMU translation table associated with the I/O device, to reflect a mapping from the physical address to a machine address associated with the remote memory device and used to identify the additional memory page.

Abstract: Illustrated is a system for performing Deep Packet Inspection (DPI) that includes a core to prepare a data packet for transmission. Further, the system includes a memory controller to direct the data packet to a DPI core. Additionally, the system includes a Network Interface Card to receive the data packet for transmission after DPI is performed on the data packet by the DPI core. The system includes a Direct Memory Management module to update a descriptor that references a received data packet stored in an Operating System buffer. Moreover, the system includes an Input/Output Memory Management Unit to direct the descriptor to be stored in a DPI memory. Additionally, the system includes an interrupt controller to transmit an interrupt to the DPI core to such that the DPI core retrieves the descriptor from the DPI memory and performs DPI on the data packet stored in the OS buffer.

Abstract: An embodiment of a method of checkpointing parallel processes in execution within a plurality of process domains begins with a step of setting communication rules to stop communication between the process domains. Each process domain comprises an execution environment at a user level for at least one of the parallel processes. The method continues with a step of checkpointing each process domain and any in-transit messages. The method concludes with a step of resetting the communication rules to allow the communication between the process domains.

Abstract: A method of restoring processes within a process domain begins with a step of restoring a tree of processes in which at least two of the processes share at least a resource. The method continues with a step of restoring a checkpoint state of each resource used by the processes after a time when a possible need for a restoration state of the resource exists. According to an embodiment, the restoration state comprises information used by the method during the step of restoring the tree of processes. According to another embodiment, the restoration state comprises information used by the method during the step of restoring the checkpoint state of one or more particular resources. The method concludes with a step of resuming execution of each process after restoration of the checkpoint state of the resources used by the process.
