Abstract

PROBLEM TO BE SOLVED: To prevent mutual communication between virtual networks and between network resources in a virtual node.
A programmer management device calculates a total for each type of resources of each virtual device as a single virtual device by merging a plurality of devices included in the programmer part. The redirector management device merges a plurality of devices included in the redirector portion as a single virtual device, and calculates and notifies the sum of the resources of each virtual device for each type. The network management device acquires the sum from the programmer management device and the redirector management device, and stores and manages them in the database in units of virtual devices.

Description

  The present invention relates to a network system resource management system and method, and more particularly, to a network system resource management system and method using virtual technology.

  A network system using a conventional virtualization technology uses a virtualization technology to virtually separate network device links and node resources into virtual links and virtual nodes, and combine the separated resources to create a network. Provides a means to create on-demand "slices" that are logical networks or service networks that are logically generated on the infrastructure, and provides a procedure for installing a network processing program on a slice-by-slice basis (For example, see Non-Patent Documents 1 and 2).

  As a result, the network operator can create a slice for each application and realize networking processing that matches the nature of the application.

  FIG. 1 is a configuration example of a network system using a conventional virtualization technology.

  The network management device (or network management system) in FIG. 1 is a resource management system that manages the entire network virtualization infrastructure. The programmer device is a device such as a dedicated (dedicated) VM server, for example, and implements a virtual node. The redirector device is a device such as an L2 switch that can set a VLAN, for example, and implements a connection (virtual link) between virtual nodes. The redirector device can control (resource separation) so that the network resources of the virtual links do not interfere with each other. A virtual network is configured by virtual nodes and virtual links. The gateway device is a device having a housing function for connecting a terminal to a network virtualization infrastructure in a virtual network. Each programmer device, redirector device, and gateway device has a management device (programmer management device or programmer management system, redirector management device or redirector management system, gateway management device or gateway management system). A resource management system that receives a slice generation control command from a management device and gives a setting command to a device to be managed.

  FIG. 2 is a configuration example when the number of programmer devices and redirector devices used in the network system using the conventional virtualization technology is increased from that in FIG.

  FIG. 3 is a resource amount holding database (DB) of a conventional network management apparatus. In the DB, resources and amounts (resource amounts) of network device programmers and redirector devices are recorded.

  FIG. 4 is a resource use retention DB of a conventional network management apparatus. In the DB, the resource amounts (resource usage amounts) of the programmer device and the redirector device assigned to the slices of the network system are recorded.

  As shown in FIG. 2, in the network system using the conventional virtualization technology, when the number of network devices increases, it becomes difficult to manage the network devices by the network management device, and when selecting resources to be allocated to the slices The route calculation time becomes longer. In addition, there is no mechanism for controlling the connection between the virtual node and the virtual link and the network resources in the virtual node when one virtual node is realized by a plurality of devices so as not to interfere with each other.

  For this reason, there is a possibility that communication will affect the communication path from the virtual node to the virtual link, causing congestion and the like.

  The present invention has been made in view of the above points, and provides a network system resource management system and method capable of preventing mutual communication between virtual networks and between network resources in a virtual node. The purpose is to provide.
