When transmitting business data, the business veneer chooses corresponding connecting lines between boards through corresponding switch according to corresponding priority information to the business data type, so as to send or receive the business data. The utility model has the advantages of realizing the method to transmit a plurality of business data through a single idle cost byte and solving the problem of inadequate idle cost byte of the frame structure during optical transmission equipment research.
Description
Technical field
The present invention relates to the frame structure in optical communication equipment field, relate in particular to a kind of method by single free consumption byte multiplexing transmission multiple business data.
Background technology
In the optical communication transmission equipment; each producer usually can the employing standard in not the free consumption byte of clear and definite predetermined function realize the demand that the user is specific; in general all be to use single free consumption byte to realize a certain special function; number of patent application CN00116468 for example: " a kind of SDH of utilization idle overhead real-time routing is realized the method for public affair protection " is exactly to use an independent free consumption byte to realize transmitting public affair defencive function content; wherein; SDH is the abbreviation of Synchronous Digital Hierarchy, that is: SDH (Synchronous Digital Hierarchy).
Yet, adopt single free consumption byte to realize that the method for the single business function of output more and more seems unable to do what one wishes because the free consumption byte number is limited.
Summary of the invention
The invention provides a kind of method, to solve the problem of frame structure free consumption byte deficiency in the optical communication equipment exploitation by single free consumption byte multiplexing transmission multiple business data.
In order to solve the problems of the technologies described above, the invention provides a kind of method by single free consumption byte multiplexing transmission multiple business data, described method comprises the steps:

Fig. 1 realizes the device structure design schematic block diagram of the method for single free consumption byte multiplexing transmission multiple business data for the embodiment of the invention;
Fig. 2 realizes the SDH network element for application example of the present invention and utilizes SDH free consumption byte F1 to realize the device structure design schematic block diagram of multiplex transmission method.
Embodiment
Below in conjunction with the drawings and specific embodiments technical scheme of the present invention is described in detail.
As shown in Figure 1, the embodiment of the invention realizes the device structure design schematic block diagram of the method for single free consumption byte multiplexing transmission multiple business data, the N kind traffic data type that will transmit according to single free consumption byte, for described single free consumption byte is provided with line between the N batten (as HW (highway) line, high speed line between plate), and be provided with that line links to each other respectively between N switch and described N batten, concrete described traffic data type is provided with different priority; Service board is according to the described priority information that is provided with, and selects by corresponding switch that line transmits described business datum between corresponding plate, thereby realizes selecting multiplexing function.This method comprises the steps:
Step 101, the N kind traffic data type that single free consumption byte will transmit in the configuration frame structure on service board, line between the N batten is being set between service board and optical transmission device, and N the switch that line links to each other respectively between setting and described N batten, the described N kind traffic data type multiplexing for needs is provided with different priority;
Step 102, when business data transmission, service board is according to the priority information of the type correspondence of this business datum, select line between corresponding plate by corresponding switch, to send or to receive described business datum: described service board is as business datum as described in sending, then send to optical transmission device, arrive light path again through optical transmission device; Receive that then direction is opposite.
In addition, represent the double-head arrow that is of single free consumption byte service data transmission direction among Fig. 1, represent service board can send or receive described business datum.
As shown in Figure 2, application example of the present invention realizes that the SDH network element utilizes SDH free consumption byte F1 to realize the device structure design schematic block diagram of multiplex transmission method, and the transmission data are public affair guard byte information and network management monitoring information, and concrete implementation step comprises:
Step 201, to transmit the function of public affair guard byte information and network management monitoring information at SDH free consumption byte F1, the SDH network element is provided with two HW lines (HW line A and HW line B) and is used for transfer data information between service board and tabula rasa, the SDH network element is provided with two to inductive switch (switch A and switch B by the different values of its register, wherein, the corresponding network management monitoring information of switch A, the corresponding public affair guard byte of switch B information), the SDH network element is used for selecting business datum to arrive the transmission of concrete HW line by these two register switch; In addition, because the webmaster transmission monitoring information is paroxysmal often, and official telephone be not require for a long time unobstructed, and the official telephone route can also select other backup paths to carry out, so transmission network management monitor message the highest priority of 1 is set, transmission public affair guard byte information lower priority 2 is set;
Step 202, the user issues which kind of type of service of the concrete transmission of configuration by webmaster to the SDH network element, when business data transmission, utilizes the priority that sets in advance, and which kind of business datum when the board software decision of SDH network element transmit, and is divided into two kinds of situations this moment:
If a user issues the order of transmission network management monitor message by webmaster to the SDH network element, height order according to priority, can preferential send or receive network management monitoring information (opening switch A) this moment (is sent as from the SDH network element to tabula rasa, arrives concrete light path again through tabula rasa; Receive that then direction is opposite), if veneer is transmitting public affair guard byte data before this, then can temporarily stop to transmit these data (off switch B), after the network management monitoring information that finishes to be transmitted and the user cancel (off switch A) after the transmission network management monitor message, recover transmission public affair guard byte information (opening switch B) again;
If b user issues transmission public affair guard byte message command by webmaster to the SDH network element, then whether the SDH network element can detect this moment in the transmission network management monitor message, if just in the transmission network management monitor message, must wait for that then end of transmission and user cancel (off switch A) behind the transmission monitoring information, just sending or receive public affair guard byte message transmission (opening switch B) (is sent as from the SDH network element to tabula rasa, arrives concrete light path again through tabula rasa; Receive that then direction is opposite).
The method of the invention is not restricted to listed utilization in specification and the execution mode.Concerning the technology of the present invention those of ordinary skill in the field, can make various corresponding changes and distortion according to the present invention, and all these corresponding changes and distortion all belong to the protection range of claim of the present invention.
