According to one embodiment of the present disclosure, an approach is provided in which a policy server receives a request for a policy from a requestor. The policy server identifies an initiating virtual machine; the initial virtual machine's corresponding virtual network; and a destination virtual machine. Next, a policy corresponding to sending data from the first virtual machine to the second virtual machine is selected. The policy includes one or more logical references to the virtual network and does not include a physical reference to a physical entity located on a physical network. In turn, a physical path translation corresponding to the selected policy is identified and sent to the requestor.

Systems and methods for remotely installing software on a computing system while the computing system is running on a first bootable image, so that the computing system is not removed from operation during the installation of a second bootable image. The method comprises constructing the second bootable image on a storage medium accessible to the computing system while the computing system is operating in a first operating environment in association with the first bootable image, customizing the second bootable image so that the computing system can operate in a second operating environment in association with the second bootable image, disassociating the computing system from the first bootable image, and associating the computing system with the second bootable image.

Systems and methods for deploying a virtual machine (VM) on a host are provided. An exemplary method comprises notifying a host to download a master copy of a VM image from a remotely located network storage device, in response to a service provider providing a definition manifest for a service request supported by the VM, wherein the host deploys the VM directly from the VM image downloaded to a storage medium locally connected to the host machine, wherein deployment of the VM allows the host to locally service the service request associated with the definition manifest, wherein the host replicates copies of the VM image, in response to receiving additional service requests to create one or more VM clones; wherein the host customizes the one or more VM clones based on the definition manifest.

The present invention relates to a method for the customization of virtual machine images. The method comprises identifying and retrieving a virtual machine image template. A customized virtual machine image is created from the virtual machine image template. The customized virtual machine image template being created by identifying at least one file-system or memory image that is associated with the virtual machine image template, identifying within the at least one file-system or memory image at least one data set, wherein the at least one data set comprises metadata. The metadata contains information detailing the required execution context customization aspects for at least one specified image subset of the virtual machine. Execution context-specific information that is required to customize the image subset of the virtual machine is retrieved. Further, the image subset of the virtual machine is modified in accordance with the retrieved execution context-specific information.

Systems and methods for migrating a virtual resource from a source host in a source network to a destination host in a destination network are provided. In one embodiment, the method comprises establishing a secure communication connection between a source proxy in the source network and a destination proxy in the destination network; and monitoring migration traffic directed from the source host to the source proxy and forwarding said traffic to the destination proxy which in turn forwards the traffic to the destination host over the secure communication connection between the source proxy and the destination proxy, such that the communication addresses of the source host and the destination host remain guarded from direct access by an entity outside of the source network or the destination network.

According to one embodiment of the present disclosure, an approach is provided in which a policy module receives data that is initiated by a first virtual machine and has a destination at a second virtual machine. The policy module selects a policy that corresponds to sending the data from the first virtual machine to the second virtual machine. The policy includes one or more logical references to one or more virtual networks, and does not include a physical reference to a physical entity located on a physical network. In turn, the policy module encapsulates the data with a physical path translation that is based upon the selected policy, and sends the encapsulated data over the physical network to a second policy module that corresponds to the second virtual machine.

A physical host executes a virtual machine monitor (VMM) in communication with a plurality of consumer virtual machines (VMs). In response to receipt of a packet, the VMM determines whether a service is to be performed for the packet by a service virtual machine (VM) in communication with the VMM. In response to determining that the service is to be performed for the packet by the service VM, the VMM applies a tag to the packet that differentiates the packet from any other packet sharing a common address with the packet but having a different associated consumer, passes the packet to the service VM for performance of the service, and thereafter removes the tag from the packet in response to receipt of the packet from the service VM following performance of the service. In response to receipt of the packet from the service VM, the VMM forwards the packet.

A method for managing communication between nodes in a virtual network is provided. A first computing system utilizes first information to forward first data to the second computing system in a physical network. If the first information is incorrect, the second computing system forwards an unlearning request to the first computing system, and the first computing system updates or deletes the first information. If the first information is not available, the first computing system forwards the first data to a group of computing systems in the physical network by way of an unknown network service. Upon receiving the first data, the second computing system or a third computing system in the physical network forwards a learning request to the first computing system, and the first computing system utilizes the learning request to generate the first information.

Data transmission system comprising a single transmitter and a plurality of receivers and in which the transmitter sends a group Gi of data items to the plurality of receivers over a one-way channel, wherein each data item to be transmitted is divided in blocks which are encapsulated to form datagrams, each datagram including a block sequence number, a data item identifier, a timestamp reflecting the age of the data item, and a group directory GD is regularly sent by the transmitter) to each one of the plurality of receivers, the group directory containing information for all groups Gi of data items being sent enabling each one of the plurality of receivers to select the group of data items it wants to receive.
摘要:
A data transmission system, including a plurality of transmitters for transmitting a stream of multiplexed packets over a broadband channel, the packets being constructed from a stream of variable length data blocks, each of the blocks originating from different sources. The system also includes a plurality of receivers for receiving the stream of packets from the broadband channel and reconstructing the stream of variable length data blocks. The data blocks are distributed over one or more packets. The packets also include a packet header having a source identifier (SID) for identifying the source of the packet, and the first of the packets further including a block header having a block identifier (BID) for identifying the data block being transmitted.
