Description
Technical field
The invention belongs to the communications field, relate in particular to a kind of professional method of on optical multiplex layer, creating.
Background technology
In the network layer webmaster, all need be for transmission network with professional (path) end to end as management object.In the service management, professional establishment function is one of basic function of network layer webmaster end to end.In traditional service creation function, business is divided into multilayer (as: what have is divided into business 12 layers), face mutually two-layer be service layer at the middle and upper levels, lower floor is a client layer, service layer's business of this service needed must be created when creating business earlier, its client layer business can be created then.And the most frequently used in these operation layers be the high-level of facing mutually, low stratum, but now, when going up the establishment business with the optical multiplex layer (MS) that high-level is faced mutually, the user must create the high-order business earlier, could create low-order service then, the route of low-order service process all is the professional composition of the service layer of high-order.Even between 2 adjacent network elements, create low-order service, also need between these 2 adjacent network elements, create service layer (HO) path of high-order earlier, and then can create low-order service.Such processing is very inconvenient to the user, if can allow the user fairly simple, can directly create the low-order service layer, then improve the friendly interface of service creation function greatly, reduce the difficulty that user learning uses this function, reduce the step of user's operation, (as: directly create the client layer business, no longer force to create service layer's business).
Summary of the invention
Technical problem to be solved by this invention provides a kind of method that can directly create the business of creating of low-order service layer in transmission network management.
Method of the present invention may further comprise the steps:
A, with all high-order business, form the link of service layer, with all multiplex section business, form the optical multiplex layer link, according to the capacity of user's input, delete the limit of those off-capacities; If more than one of the link between the network element then only keeps the link of weights minimum;
The weights that B, user connect by " adjustment " light come the cost of " adjustment " high-order route and low order route, and computer is sought a suitable route automatically by computing and formed business.
The weights that " adjustment " light connects among the described step B are that the multiplex section link metric is enlarged K doubly.This is a kind of method of the weights of " adjustment " light connection.
The weights that " adjustment " light connects among the described step B are for being reduced into S doubly with high-order link metric and low order link metric.This is the another kind of method of the weights of " adjustment " light connection.
Described K value is infinitely great.This situation is not used the multiplex section link, and the path that create this moment is consistent with the traditional network management result calculated.
Described K value is 1.This situation multiplex section link is identical with the high-order link, does not preferentially use the high-order route.
Described K value is the numerical value among the 2-9.In this case, can the strategy of preferred high-order link be set according to the difference of K value.
Described K value is 5.A preferable K value when this is preferred high-order link.
The present invention is owing to hint obliquely at into topological diagram with optical multiplex layer, high-order operation layer with low-order service on light connects.So multiplex section layer MS layer service not only comprises the capacity of high-order, also comprise the capacity of low order simultaneously.The user can allow computer calculate the cost of high-order route and low order route automatically by the weights that " adjustment " light connects, thereby there has been the user on optical multiplex layer, can directly set up the possibility of low-order service layer, improve the friendly interface of service creation function greatly, reduce the difficulty that user learning uses this function, reduce the step of user's operation.
Description of drawings
Fig. 1 is the networking situation that comprises MS and HO layer simultaneously;
Fig. 2 is that customer requirements is only created the low order path on the HO layer;
Fig. 3 directly creates low-order service embodiment K=1 at the MS layer;
Fig. 4 directly creates low-order service embodiment K=3 at the MS layer.
Embodiment
The invention will be further described below in conjunction with accompanying drawing and preferred embodiment.
Design principle once at first is described.
Want on light connects, directly to create low-order service, have two problems to need to solve.
At first: when creating low-order service, need on high-order service layer business and MS layer service, seek the path simultaneously.The business of MS layer does not directly comprise the volume of business of low order in network layer webmaster in the past, and then the low-order service of Chuan Jianing just can not be carried on the MS layer service.
Secondly: if route has short high-order service layer business, then use high-order service layer business as the low order route, cost is lower, should be preferential.This just requires algorithm that a trade-off is preferably arranged between high-order route and MS route.
These two problems solve in order to following method respectively,
1, on light connects, optical multiplex layer, high-order operation layer are hinted obliquely at into topological diagram with low-order service.Multiplex section layer MS layer service not only comprises the capacity of high-order like this, also comprises the capacity of low order simultaneously.
2, the weights of user's " adjustment " light connection, computer calculates the lower route of cost according to the size of adjusted weights.
Below in conjunction with the description of drawings method step among the embodiment once:
1,, forms the link of HO layer, as A-＞D among Fig. 1＞Z with all high-order business.
2,, form the MS link, as A---＞B---among Fig. 1＞C---＞Z with all multiplex section business.
3,, delete the limit of those off-capacities according to the capacity of user's input.
If more than one of the link between 4 network elements then only keeps the link of weights minimum.
5, according to the user to the instructions for use of multiplex section link (do not use the multiplex section link, the multiplex section link is identical with the high-order link, preferentially uses the high-order link), adjust the COEFFICIENT K assignment.
If 6 customer requirements only (do not use the multiplex section link) and create the low order path on the HO layer: then K=infinity (herein=100) as shown in Figure 2, is tried to achieve path shortest path-A＞D-＞Z.The path that create this moment is consistent with the traditional network management result calculated.
If 7 customer requirements multiplex section links are identical with the high-order link, K=1 then is set, preferentially do not use HO.This moment networking diagram such as Fig. 3.
8, trying to achieve shortest path is A--＞B-＞C-＞Z, and weights are 9.2+3+4＝9。
9, this moment, professional route was passed through MS layer link, so need set up the high-order business earlier at MS layer link, set up low-order service again on this high-order business.
High-order business, low-order service are selected and set up to step 8,9 all by computer by calculating automatically.
10, preferred if desired HO then is provided with K=3.Networking this moment such as Fig. 4.
11, asking shortest path is A-＞D-＞Z, and weights are 22 (if choose the MS layer link that route is A-＞B-＞C-＞Z this moment, then weights are 27).
Step 11 is selected by calculating automatically by computer.
12, therefore, according to the difference of K value, the preference policy of HO is set, the general choosing value of K value scope (comprises two ends point value 2,9) between 2-9.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, as: also can be by high-order link metric and low order link metric are reduced into the weights that S doubly comes " adjustment " light to be connected; Also the K value also can be set to 5 etc., all should be considered as belonging to protection scope of the present invention.
