Description
Technical field
The utility model relates to a kind of ring of light web frame of the improvement of the electric network composition in the powerline network field of SDH the optical transport communications field, particularly early origin.
Background technology
The transmission technology mainly SDH that current power telecommunication network adopts.SDH transmission technology is still the main flow transmission technology of power telecom network, transmission rate is high, and transmission delay is little, can form Self-healing Rings network, it be current standardization level the highest, facts have proved the most reliable transmission technology, be widely used in power telecom network.But traditional SDH equipment is for circuit-switched service optimal design, and only provide PDH, SDH series rate interface, when the arrowbands such as voice, data, image and wide band multi-business coexist, its limitation becomes increasingly conspicuous.And the preferred plan addressed this problem, be adopt multi-service transport platform MSTP technology to transform communication network.MSTP is based on SDH platform, realizes the service accesses such as TDM, ATM, IP, process and transmission simultaneously, provides the multi-service transport platform of united net management.By the utilization of this technology, the multi-service transportation demand that power telecommunication network is growing can be met, remain again the advantage of SDH equipment, as network protection, fault/performance monitoring etc., for power system security production, operation provide reliable guarantee.Through investment construction for many years, electric power system has now begun to take shape a communication network be made up of communication.Regional power grid scheduling and safety in production, information transmission, dispatching telephone provide means of communication,
Along with business demand is in continuous change, the communication technology is in develop rapidly, and the SDH transport network architecture built up in early days and capacity all cannot meet to be produced and security needs.The construction of powerline network needs constantly perfect, and the networking of its every one-phase both should meet medium-term and long-term growth requirement, had considerable adaptability again to networking at a specified future date, protection existing investment.
Existing network transannular business is more, and must dispatch via central apparatus, and scheduling node is single, causes slot efficiency on transmission ring low.
Due to network configuration and appearance quantitative limitation, cause network configuration data complex, the regular maintenance difficulty of attendant to equipment, network is very big.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of electric network composition to make layer of structure more clear, solves the powerline network off-capacity that existing electric network composition is formed, the power communication ring of light web frame of the problems such as unreasonable structure.
The utility model realizes like this, a kind of power communication ring of light web frame, comprise a backbone network and multiple nets, backbone network is set up at least 3 transformer stations, 10G optical transmission device is set in each transformer station, 10G optical transmission device as host node by transformer station is formed core loop configuration, an each net is set up multiple transformer station according to the distance in geographical position, and 2.5G optical transmission device is set in each transformer station, Ci Zhiwang transformer station is formed time loop configuration as minor node by optical cable by 2.5G optical transmission device, the any two points that in secondary loop configuration, any two minor nodes are linked at backbone network by optical cable forms ring network structure.
The configuration of 10G optical transmission device has many ADM equipment of STM-1, STM-4, STM-16, STM-64 combination of interfaces.
5 2.5G optical transmission devices are at least comprised in described loop configuration.
OSN 3500 optical transmission device is set in backbone network transformer station and accesses to 10G optical transmission device with 2.5G speed, as the extensible frame of 10G optical transmission device.
Compared with prior art, beneficial effect is the utility model:
A) make network layer more clear
Original network structure networking made into form 10G core looped network by several key node, other original node forms multiple 2.5G looped network respectively in the mode of 2 accesses.Make network configuration clear like this, be convenient to management.
B) relaying protection service security reliability is improved
At the many core node of two business as relaying protection, can share relaying protection business.
C) situation of crossing deficiency and slot anxiety is alleviated
Ring-like network structure effectively can avoid the situation of indivedual website crossing wretched insufficiency, can also save the slot of a set of photosystem in addition, alleviates the situation of slot anxiety
D) one or several VC4 bandwidth on ring can be utilized to transmit Ethernet service, to bring facility to the unified planning of the whole network business and maintenance, and avoid the shortcoming of channel protection ring establishment Ethernet shared service, fail safe improves greatly simultaneously.
E) on the basis of existing transmission technology, only need increase several platform SDH 10G optical transmission devices newly, a small amount of 2.5G Optical Fiber Interface Board of dilatation, a small amount of cross board of upgrading just can realize the capacity expansion and upgrading to the whole network.Make full use of original lightguide cable link and equipment, greatly reduce cost.
