Intelligent optical network system and user group management method

Abstract

Operation of initial configuration for user group is carried out through management plane; or operations such as dynamic user logon, applying for building connection, disconnecting connection, modifying connection etc. can be carried out through client end. Action of control plane is in use for responding request from user end and management plane to carry out procedure for dynamic creating link. Management for user group in optical virtual private network (VPN) is implemented through service management module of management plane so as to avoid unreliability and out of time of PIT table for expanding user member through route protocol as well as security of user group management. The invention increases efficiency for building and managing VPN, and generates visible topological view of user network rapidly through address table of member of global group so as to guarantee reliability for managing OVPN group as well as expand network of multiple operation managers expediently.

Description

technical field [0001] The invention relates to an intelligent optical network system and a method for managing user groups through a management plane of an optical virtual private network, in particular to a method for quickly and reliably realizing the establishment of an OVPN (optical virtual private network) in the field of intelligent optical networks. Background technique [0002] The transmission network architecture based on the automatic switching optical network creates conditions for the provision of new services and promotes the evolution from the transmission network to the service network. Various new service provision modes are constantly emerging. With the development and research of ASON technology, the realization of these new business models has become a key technology for ASON research. Operators widely require support for new technologies such as OVPN and BOD. The provision of services, therefore, the development of smart node devices to support and impl...

Problems solved by technology

[0011] The above is the OVPN network establishment mechanism based on the automatic discovery of the DDRP protocol extension. The problem with this mechanism is that the PIT must be diffused through the routing protocol between multiple user ports. The protocol basis can be the OSPF-TE protocol based on the optical network extension. Or the BGP-4 protocol, in the case of a relatively large node scale, it will be very difficult to spread the PIT table through the routing protocol, and it is impossible to ensure that other members in the group can be quickly discovered. When the network scale increases and the network layer increases, further The complexity is also due to the possible use of different routing protocols to expand the risk of interconnection and intercommunication; when the failure of individual nodes cannot be discovered by other members in the group in time, the latest PIT table cannot be obtained in time; the user group cannot be effectively For management, there are difficulties in the implementation of security mechanisms, service levels, and unified management of protection and recovery mechanisms; it is difficult to implement billing management; it is difficult for operators to conduct a unified view and management of the current resource usage of each OVPN group, etc.
