Systems and methods for live migration of VMs between different nodes are provided. More specifically, the system and methods utilize a heat map and an access pattern to determine the fetching order of files and/or blocks from the cache of a host node for rebuilding the cache on a destination node. Additionally, the systems and methods are able to persist the cache of a host node across a crash, allowing a destination node to fetch blocks and/or files from the cache on the host node after a crash instead of having to access the VM files and/or blocks from an original source. Accordingly, the systems and methods decrease migration latency of the VM during live migration and free up network bandwidth during the live migration when compared to prior systems and methods that utilize just the heat map to determine the fetching order and/or that are not able to persist the cache across a crash.

The present invention discloses a method and an apparatus for establishing a link between virtualized network functions. The method includes obtaining an internet protocol (IP) address of a connection point (CP) of a first virtualized network function (VNF) and identification information of the CP. The method also includes determining identification information of a second VNF corresponding to the identification information of the CP of the first VNF, sending the IP address of the CP of the first VNF and the identification information of the CP to the second VNF corresponding to the identification information of the second VNF. Additionally, the method includes starting a link connection establishment process between a CP of the second VNF and the CP of the first VNF.

A method of deploying a network service (NS) across multiple data centers includes identifying virtual network functions (VNFs) associated with the NS in response to a request for or relating to the NS, generating commands to deploy VNFs based on VNF descriptors, and issuing the commands to the data centers to deploy VNFs. The data centers each have a cloud management server in which cloud computing management software is run to provision virtual infrastructure resources thereof for a plurality of tenants. The cloud computing management software of a first data center is different from the cloud computing management software of a second data center, and the commands issued to the first and second data centers are each a generic command that is not in a command format of the cloud computing management software of either the first data center or the second data center.

[Problem] To enable a user to control a virtualization system without wasting resources. [Solution] A virtualization system containing an operation unit, an operation reporting unit, a message processing unit, and an operation processing unit. The operation unit outputs a signal on the basis of a user operation. The operation reporting unit transmits to a network an operation message generated by appending, to first operation information indicating the content of the operation corresponding to that signal, a header addressed to a server providing virtual machines. The message processing unit generates second operation information indicating that the operation indicated with the first operation information has been performed with respect to the virtual machine corresponding to the transmission source of that operation message. On the basis of the second operation information, the operation processing unit instructs the virtual machine corresponding to the transmission source to perform the action corresponding to that operation.

Provided a management apparatus including a maintenance mode setting unit that transitions a first virtualization infrastructure (NFVI0) to a maintenance mode, a mobility control unit that at least instructs a virtualization deployment unit (VDU) on the first virtualization infrastructure in the maintenance mode to move to a second virtualization infrastructure (NFVI1), and a maintenance mode release unit that releases the maintenance mode of the first virtualization infrastructure (NFVI0).

The management computer has a memory which stores management information and management programs, and a CPU which refers to the management information and executes the management programs; the management information includes storage management information for allowing determination as to whether the plurality of storage resources can be paired in a redundant configuration, and couplable configuration management information for determining whether the plurality of storage resources and the plurality of server resources can be connected to each other; and when the CPU deploys a virtual machine, the CPU first determines, by reference to the storage management information, storage resources to be paired in a redundant configuration, then selects, by reference to the couplable configuration management information, server resources each of which can be connected to a respective one of the storage resources that are to be paired in a redundant configuration, and pairs the selected server resources in the redundant configuration.

Systems, methods, and computer-readable media provide for collection of statistics relating to network traffic between virtual machines (VMs) in a network. In an example embodiment, a virtual switch hosted on a physical server provides network address information of VMs deployed on the physical server to a virtual switch controller. The controller collects this network address information from each virtual switch under its control, and distributes the aggregate address information to each switch. In this manner, the controller and each switch within the controller's domain can learn the network address information of each VM deployed on physical servers hosting switches under the controller's control. Each virtual switch can determine a classification of a frame passing through the switch (e.g., intra-server, inter-server and intra-domain, or inter-domain traffic), and statistics relating to the traffic. In an example embodiment, the virtual switch controller can collect the statistics from each switch within its domain.

A method is provided in one example embodiment and includes receiving by a network element a request from a network device connected to the network element to update a shared resource maintained by the network element; subsequent to the receipt, identifying a Base Address Register Resource Table (“BRT”) element assigned to a Peripheral Component Interconnect (“PCI”) adapter of the network element associated with the network device, wherein the BRT points to the shared resource; changing an attribute of the identified BRT from read-only to read/write to enable the identified BRT to be written by the network device; and notifying the network device that the attribute of the identified BRT has been changed, thereby enabling the network device to update the shared resource via a Base Address Register (“BAR”) comprising the identified BRT.

A computing device includes communications circuitry to communicate with a first access network and processing circuitry. The processing circuitry is to perform operations to transmit an authorization request for a vehicle-to-everything (V2X) communication to a V2X application function within a service coordinating entity, the request transmitted from the device via the first access network V2X configuration parameters are received from the service coordinating entity, via the first access network. The V2X configuration parameters are received in response to the authorization request and based on V2X subscription information received by the V2X application function via a V2X application programming interface (API) within the service coordinating entity. A V2X communication link for the V2X communication is established with a second device based on the V2X configuration parameters, the second device associated with a second access network.

Various systems and methods for implementing an edge computing system to realize 5G network slices with blockchain traceability for informed 5G service supply chain are disclosed. A system configured to track network slicing operations includes memory and processing circuitry configured to select a network slice instance (NSI) from a plurality of available NSIs based on an NSI type specified by a client node. The available NSIs uses virtualized network resources of a first network resource provider. The client node is associated with the selected NSI. The utilization of the network resources by the plurality of available NSIs is determined using an artificial intelligence (AI)-based network inferencing function. A ledger entry of associating the selected NSI with the client node is recorded in a distributed ledger, which further includes a second ledger entry indicating allocations of resource subsets to each of the NSIs based on the utilization.
