Description
Technical field
The present invention relates to communication field, relate in particular to the method and system that the Ethernet private line service is safeguarded in a kind of ASON network.
Background technology
Along with the day by day increase of backbone network capacity and the variation of metropolitan area access capability, the demand that transmission network is possessed good adaptive ability is progressively brought into schedule, and the solution that the network bandwidth is carried out dynamic assignment and has a high performance-price ratio has been the target that people pursue.The New Generation Optical network technology that ASON (Automatic switched optical Network, ASON) arises at the historic moment under such market environment just.In ASON, business can realize dynamic connection, time interval resource also can carry out dynamic assignment, its principle is to increase one deck control plane at existing optical-fiber network, and utilize this layer control plane to come to connect for the user, provide and serve and bottom-layer network is controlled, support simultaneously different technical schemes and different business demands, possess the characteristics such as high reliability, extensibility and high-efficiency.
(the Ethernet Private Line of EPL in ASON, the privately owned special line of Ethernet) business provides CIR (Committed Information Rate, committed information rate) by connection oriented service layer network (be commonly referred to as and transmit network) for it.The connection of EPL business relates to three layers, be called EC (Ethernet Connection, the Ethernet connection), VCAT (Virtual Concatenation, Virtual Concatenation) connection and VC (Virtual Container, virtual container) connect, wherein the VC connection can be VC-4 connection, VC-12 connection etc.The EPL business is set up in the process, if network failure occurs, can cause EC and the VCAT link information of the head and the tail father of node inconsistent.After the EPL business is successfully established, may need to make amendment to the EPL business of original foundation because of user's demand or the fault of network etc., wherein, the revised context of EPL business comprises that mainly the increase of EPL bandwidth is connected EC and connects parameter and be connected parameter etc. with VCAT with minimizing.If network breaks down in modification process, can cause the professional upper strata of the EPL link information of head and the tail node inconsistent.For example, first node VCAT member increases successfully when increasing the EPL service bandwidth, and tail node is owing to transmitting the plane and break down and cause increasing VCAT member's failure, cause the VCAT number of members of head and the tail node inconsistent, this moment, the actual EPL bandwidth of head and the tail node was different, had had a strong impact on professional normal operation.Restart after and for example first node parameter is successfully modified when the EPL parameter modification, and tail node is not received the request of EPL parameter modification, wait until that the first node EPL that powers on connects and can cause the parameter of head and the tail node inconsistent situation to occur after being successfully recovered.Cause like this network resources waste, affected the normal operation of EPL business.
Summary of the invention
