SIGNALING METHOD OF AN O-UNI(OPTICAL-USER NETWORK INTERFACE) FOR CHANGING OPTICAL-VIRTUAL PRIVATE NETWORK CONNECTION SETTING CONFIGURATION, PARTICULARLY CONCERNED WITH DETERMINING AN ORDER OF O-UNI SIGNALING SO AS NOT TO CAUSE DISCONNECTION AMONG CLIENT SYSTEMS DURING CONNECTION SETTING CONVERSION

摘要

PURPOSE: A signaling method of an O-UNI(Optical-User Network Interface) for changing an O-VPN(Optical-Virtual Private Network) connection setting configuration is provided to minimize time required for O-VPN connection setting conversion without causing a temporary separation among client systems. CONSTITUTION: Connections to be released and connections to be generated are selected. Connections, which would not cause the separation of a current O-VPN although they are released, are searched from the connections to be released and then released. Connections, which can be currently generated, are searched from the connections to be generated and then generated. The connections to be released and the connections to be generated are repeatedly released and generated until there remains no connection to be released or generated.
