Virtual network management method, virtual network management program, virtual network management system, and virtual network means
First Claim
1. A virtual network management method for a virtual network management system configuring different virtual networks for different services, including:
- at least one network switch;
at least one managed server for managing a service;
a service management means for managing the service to be processed by the managed server; and
a virtual network management means for controlling connections by the network switch, the method comprising the steps of;
allowing the service management means to hold a mapping of the service and the virtual network;
causing the managed server to send a notification including address information of the managed server to the virtual network management means, upon status change of the managed server;
causing the virtual network management means to receive the notification including the address information from the managed server;
causing the virtual network management means to receive information from the network switch, wherein the information from the network switch indicates a relation between the address information of the managed server and a connection port of the network switch;
causing the virtual network management means to identify the managed server and the connection port of the network switch dynamically upon status change of the managed server, by referring to the address information included in the received notification and the information which indicates the relation between the address information of the managed server and the connection port of the network switch; and
causing the virtual network management means to configure the virtual network corresponding to the service dynamically, for the identified connection port.

Abstract
The invention relates to a network management method wherein: a service management equipment holds the mapping of services and virtual networks as management information; a managed server sends an advice to a VLAN management equipment when its status changes; and the VLAN management equipment receives the advice and refers to the information contained in the advice to thereby identify the managed server and the connection port of a network switch, and configures a virtual network belonging to the identified port of the network switch. The method alleviates the task of reconfiguration associated with the adding or deleting of servers.

6. A virtual network management system configuring different virtual networks for different services, including:
- at least one network switch;
at least one managed server for managing a service;
a service management means for managing the service to be processed by the managed server; and
a virtual network management means for controlling connection by the network switch, wherein;the service management means has a function of holding a mapping of the service and the virtual network as management information; the managed server has a function of sending a notification including an address information of the managed server to the virtual network management means, upon status change of the managed server; and the virtual network management means has functions comprising; receiving the notification including the address information from the managed server, receiving information which indicates a relation between the address information of the managed server and a connection port of the network switch from the network switch, identifying the managed server and the connection port of the network switch dynamically upon status change of the managed server, by referring to the address information included in the received notification and the information which indicates the relation between the address information of the managed server and the connection port the network switch, and dynamically configuring the virtual network belonging to the identified connection port.

7. A virtual network management means for a virtual network management system configuring virtual networks, in a system including:
- at least one network switch;
at least one managed server for managing a service;
service management means for holding a mapping of the service and a corresponding virtual network as management information, and managing the service to be processed by the managed server; and
the virtual network management means for controlling connection by the network switch, the virtual network management means implementing functions comprising;receiving a notification, upon status change of the managed server, including an address information of the managed server and the status of the managed server; receiving information from the network switch, wherein the information from the network switch indicates a relation between the address information of the managed server and a connection port of the network switch; identifying the managed server and the connection port of the network switch by referring to the address information included in the received notification and the information that indicates the relation between the address information of the managed server and the connection port of the network switch; and dynamically configuring the virtual network belonging to the identified connection port.
- at least one network switch;
