Description
Technical field
The present invention relates to the business collocation method of SDH (Synchronous Digital Hierarchy, i.e. SDH (Synchronous Digital Hierarchy)) optical transport network, more particularly, relate to connection-oriented manual business collocation method in a kind of SDH optical transport network.
Background technology
At present, the SDH optical transport network has obtained using widely at communication field, progress along with the demand and the technical merit of society, the bandwidth of SDH optical transport network is more and more wideer, particularly mostly adopted 2.5G bit/s even SDH equipment more at a high speed in trunk cable, this just makes seem all the more important of the business configuration function of SDH optical transport network.
In the webmaster platform system of existing SDH equipment both domestic and external, the management function of business configuration is arranged all mostly, its method can be divided into two classes:
One, automatic service configuration feature
Under this function, can realize of the automatic configuration of source end to the SDH business configuration to destination, the network element of middle process is sought automatically by the automatic service configuration feature, and distributes bandwidth and take according to the conditions of demand of business configuration, reinforms network element and does corresponding action and guarantee professional unobstructed.The advantage of this method is that the user is simple to operate, and shortcoming is that the intermediate NE that finds is realized by the automatic service placement algorithm fully, and is invisible fully to the user in the selection course.If to the purpose network element, mulitpath is arranged, select any bar user uncontrollable from the source network element.In the operation of reality, find, because the automatic service configuration provides the path by algorithm, the business that some originally can dispose, algorithm but draws the wrong conclusion that can't dispose, and just can realize configuration and use manual method instead.When business being carried out some small lots modifications, the user need control the network element of process, also can't realize in method of automatic configuration, need be by manual configuration in addition.
Two, manual business configuration feature
Under this function, the user will participate in professional network element and be configured respectively one by one, and choose the relevant minimal service dispensing unit of the related single-boards of each network element.With in the network all network elements all dispose finish after, corresponding service just can have been led to.The advantage of this method be business configuration to the user entirely as seen, be convenient to business configuration and carry out according to user's requirement.Shortcoming is that the source network element, intermediate NE, purpose network element etc. that the process of configuration has lost every business flow to information, and the business configuration pointwise is carried out, and makes mistakes easily.If there is business only to dispose source network element and intermediate NE, and the purpose network element is not when doing corresponding configuration, data still can dispose to the network element except that the purpose network element, make the bandwidth of these network elements be in seizure condition, cause a large amount of junk datas, so that when disposing once more, the business configuration that can carry out originally, it is not enough and can't dispose to be considered to bandwidth.
Summary of the invention
Manual intervention completely can't be realized in order to have overcome in the existing SDH optical transport network technology automatic service configuration, shortcoming such as error configurations conclusion may be drawn, and manual configuration loses professional consistency, makes mistakes easily, layoutprocedure complexity, speed wait shortcoming slowly, the invention provides a kind of consistency that had both kept business configuration, transparent fully to the user again, have connection-oriented manual business collocation method in repeatability, the efficient and easy-operating SDH optical transport network simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of connection-oriented manual business collocation method, basic thought is: the professional business that is configured to from the source network element to the same type of purpose network element is an allocation unit, and must successively each network element be configured respectively according to order from the source network element to the purpose network element, business configuration towards the connection between network element rather than usually the manual business configuration towards the network element mode; To the user as seen all configuration detail can all select configuration by the user in the layoutprocedure; In the layoutprocedure, the webmaster platform reasonably screens the data of user's request, and the data that only will satisfy user's condition offer the user, with complexity that reduces manual configuration and the speed of accelerating configuration; After user's configuration was finished, the webmaster platform checked that to the integrality and the consistency of configuration data the data that will meet check criteria write database, otherwise data are invalid, and the user must reconfigure; Guarantee that in such a way configuration data is revised or be complete modification, or be cancelled.
The data that above-mentioned connection-oriented manual business layoutprocedure generates, adopt the mode of " affairs " in the similar database to manage: the data that generate to the whole layoutprocedure of purpose network element at the source network element are as one " affairs ", promptly, data must be complete, must comprise from the source network element and begin all to generate up to all data of purpose network element through intermediate NE, can think that just these data are effectively, just can write in the database of webmaster platform.If lost the data of certain intermediate point wherein or caused certain or the more heterogeneous pass configuration data that does not have the purpose network element for a certain reason, then this data are all invalid by the gross, must begin to be configured from the source network element again.Adopt this data management mode to guarantee data modification or be complete modification, or be cancelled.All these data modifications all are based on " affairs ".In one " affairs ", can do the institute busy or what do not do.
For guaranteeing to adopt the layoutprocedure of connection-oriented business collocation method to have repeatability, that is, the difference with operating personnel does not cause configuration data or professional difference through network element.When the webmaster platform provided a plurality of feasible paths and selects to the user, every paths all will be indicated its characteristics among the present invention: minimum through the node number for make final configuration through certain node, then this node specification place indicates that the node number is minimum; The shortest for make final configuration through certain node through physical pathway, then indicate that at this node specification place physical pathway is the shortest; Minimum for make final configuration through certain node through topological ring, indicate that then topological ring is minimum.Simultaneously, each network element is all indicated the order (the shortest as physical pathway, topological ring second is few, and node the several the 3rd is few) of these three indexs.Like this, in case after the business configuration general principle of a network is determined, just can select through which intermediate node, and not change with operating personnel's variation according to the characteristics that the node place is indicated.Yet being operated by the professional of business configuration do not advise that anyone operates on it simultaneously.
Core algorithm is:
The first step, webmaster platform requester network topological database, inquiry has the network element of idle bandwidth, and all results is inserted network element select row, if all bandwidth of network element are all occupied, then this network element is labeled as busyly, during the idle network element of inquiry next time, no longer provides this network element;
