OVPN system, OVPN terminating device, collective controlling device, and optical communication network

摘要

An OVPN user register an L1 signal type information which is used in the user's device in an OVPN terminating device in advance together with an IP address and a VPNID which are allocated to the user's device. Registered contents are notified to other OVPN terminating devices which control the same VPNID as that of the user's device. Otherwise, when a calling connection request arrives from the user's device, the registered contents are notified other OVPN terminating devices which control the devices which receive the notification. By doing this, it is possible to handle a request by the user for changing the setting for the signal format which is employed in the user's device quickly. Also, it is possible to realize an OVPN which can perform a process for a calling connection request from the user efficiently and improve an operability for the user.
