Description
Technical field
It is specially the transparent transmission device and thoroughly of a kind of duties and webmaster based on ASON the present invention relates to ASON technical fields
Transmission method.
Background technology
The automatic optical transfer network that exchanges based on Synchronous Digital Hierarchy (SDH) and optical transfer network (OTN) is known as ASON
(Automatically Switched Optical Network).Traditional such communication network main line is by multiple manufacturers
ASON equipment composition, such as by China Huawei, in the ASON equipment networks of the manufacturer such as emerging, flames of war form.Some special
In the ASON networks of purposes, the ASON equipment common networkings of different vendor are generally required.In existing technical merit and manufacturer's skill
In the case of art opening, because the business interface of ASON equipment has identical standard, the ASON equipment of different vendor collectively constitutes
ASON networks, interconnecting for business interface can be conveniently realized, i.e., the SDH optical signals between different ASON equipment can
Mutually to transmit, therefore business information can normal communication.
But the duties of this ASON networks and the processing protocol of webmaster there is no unified standard till now, therefore different factories
Duties and the mutual normal communication of network management information can not be realized between the ASON equipment of business.When A factories equipment passes through B plants
When connecting another equipment of A factories, since the ASON equipment standards of A, B factory are different, B plants are in the duties to reception and network management information
When being parsed, meet the processed of the duties of B plants and network management information standard, and A plants are transmitted through duties and the webmaster come
Information, not meeting the duties of B plants and network management information standard will be dropped.Since B plants do not possess different duties and webmaster
The transparent transmission function of information, the duties and network management information for causing the transmission of A plants are abandoned by B plants, and another equipment of A factories can not
Receive duties and the network management information of A plants.
At present, in the specific use network that the ASON equipment of different vendor is set up jointly, how duties and webmaster to be realized
Normal management and communication, it has also become ASON networks crucial design problem anxious to be resolved.
The content of the invention
The purpose of the present invention is design a kind of transparent transmission device of duties and webmaster based on ASON, including optical signal prosessing mould
Block, SDH spending process modules and DCC spending process modules, when in network between the first equipment of ASON and the 3rd equipment of A factories also
There is the second equipment of ASON of the B factory different from the ASON equipment of A factories, and mutually interconnected by a playscript with stage directions transparent transmission device by optical fiber
Connect, the optical signal of the first equipment of ASON from A factories is introduced into the optical signal prosessing module of this transparent transmission device, is converted to electric signal
SDH data, extract the DCC overhead datas in SDH data, i.e. duties and network management information in SDH spending process modules, and DCC is opened
Pin processing module handles DCC overhead datas, and overhead byte is re-fed into SDH by correlation timing according to webmaster order
Overhead bus.Business information is then returned again to by service channel by the second equipment；Business information and the DCC overhead datas after processing
SDH data are complex as, finally change heliogram, the 3rd equipment of ASON of access A factories.The transparent transmission device of the present invention makes A factories
The duties of the first equipment of ASON and network management information will not be dropped in the second equipment of B factories, realize the business letter of three equipment
While ceasing normal communication, also achieve duties that the first equipment of ASON of A factories sends and network management information is transparent to through the present apparatus
3rd equipment.
It is another object of the present invention to design the transmitting method of a kind of duties based on ASON and webmaster, by the ASON of A factories
The optical signal of first equipment is converted to the electric signal of the SDH data of the overhead data containing SDH, by frame decoding, extracts in SDH data
DCC overhead datas --- i.e. duties and network management information, and business information is dealt into the second equipment of ASON of another different B factories；
DCC overhead bytes are re-fed into overhead bus by correlation timing further according to webmaster order, the present apparatus will insert A factories afterwards
The business information multiplexing framing of the SDH overhead datas of DCC overhead datas and the second equipment of ASON access present apparatus of B factories obtains
SDH data sending electric signals, are finally converted to transmission optical signal, the 3rd equipment of ASON of A factories are sent into, in two ASON of A factories
When the ASON equipment of B factories is connected between equipment, while realizing business information normal communication, across B factories ASON second between realization
Duties and network management information transparent transmission between the ASON equipment of the Liang Tai A factories of equipment.
The transparent transmission device of a kind of duties and webmaster based on ASON that the present invention designs, including optical signal prosessing module, SDH
Spending process module and DCC spending process modules.
First, second, and third equipment through optical fiber by being connected based on the duties of ASON with the transparent transmission device of webmaster, first
