Embodiment
The embodiment of the invention provides a kind of service control method, does not have in order to the business that realizes BAS Broadband Access Server and interrupts switching, and is as shown in Figure 1, specifically comprises:
In the embodiment of the invention; For more convenient more clearly description scheme; The subject of implementation of at present setting service control method in the embodiment of the invention is a business control device; Business control device can be integrated in the network management center server, also can be integrated in other servers or the equipment, can also be as an independently server or an equipment existence.A preferable selection is that business control device is integrated in the network management center server, can utilize the mass data about BAS Broadband Access Server of storing in the network management center server.
Generally, there are a large amount of state informations of BAS Broadband Access Server in the network management center server, like hardware running status, operation system state, veneer load, protocol running state, the load capacity of BAS Broadband Access Server, or the like.Business control device can obtain the current state information of BAS Broadband Access Server from the network management center server; And analyze, judge and make a strategic decision according to the state information of obtaining; Send control command to BAS Broadband Access Server, to avoid the professional professional more optimization that occurs interrupting or carrying out; Certainly, business control device also can be collected the current state information of BAS Broadband Access Server through other means, for example, directly links to each other with BAS Broadband Access Server, obtains current state information.
In the specific implementation, BAS Broadband Access Server can have polytype, as can be by bandwidth (getting final product access customer number) classification, also can be by the classification that carries on an agreement, or the like.During enforcement; A kind of more excellent mode classification is to classify by amount of bandwidth; Set a bandwidth threshold; Can be called first kind BAS Broadband Access Server with what bandwidth was higher than this threshold value, bandwidth is lower than the second type of BAS Broadband Access Server that be called of this threshold value, the concrete numerical value of bandwidth threshold is decided by concrete condition.For example; Can the BAS Broadband Access Server of bandwidth more than 10K be classified as first kind BAS Broadband Access Server; The BAS Broadband Access Server of bandwidth below 10K is classified as second type of BAS Broadband Access Server, and what this type used morely usually is that bandwidth is the BAS Broadband Access Server of 1K to 2K.
Because first kind BAS Broadband Access Server bandwidth is higher; For guaranteeing professional reliability; When first kind BAS Broadband Access Server is applied to business, just disposed corresponding backup server, when the port of first kind BAS Broadband Access Server and route break down; The first kind BAS Broadband Access Server that breaks down can switch to its corresponding backup server voluntarily, but can't consider for other faults.
And in the embodiment of the invention; In step 102, business control device can be determined first kind failed server according to the current state information of first kind BAS Broadband Access Server; Except that port and routing failure; Can also find the system failure of current first failed server, like the access process failure, or the like.After determining first kind failed server, business control device notice first kind failed server switches to business on its corresponding backup server, by its corresponding backup server business that continues.In this example; The annexation of business control device and first kind BAS Broadband Access Server is as shown in Figure 2, carries out transfer of data between the first kind BAS Broadband Access Server backup server corresponding with it, like the data of transport service information table; Carry out the transmission of control command (like switching command) with business control device; Wherein, the transmission of dotted line representative data, solid line representative instruction transmission.First kind failed server switches to backup server with business after receiving switching command, and backup server activates the backup traffic of storage.
Describe with an instantiation, suppose that in this example first kind BAS Broadband Access Server is BRAS1 at present; Its corresponding backup server is BRAS2; When the access process of BRAS1 breaks down, but port and route are normal, at this moment; Message control module confirms that BRAS1 breaks down, and notice BRAS1 switches to BRAS2 with business.
Certainly; Be the promptness that guarantees to switch; Determine when having port or routing failure when first kind BAS Broadband Access Server, still can automatically business be switched on its corresponding backup server, when receiving the switching notice of business control device more afterwards; Owing to stop business, can't exert an influence to business.
In one embodiment; The annexation of second type of BAS Broadband Access Server and business control device is as shown in Figure 3, and data and control command are all transmitted between second type of BAS Broadband Access Server and business control device, wherein; The transmission of dotted line representative data, solid line representative instruction transmission.Step 104 is when implementing; Business control device can be according to the current state information of second type of BAS Broadband Access Server; Determine second type of failed server, comprise all second type of faults that BAS Broadband Access Server may be found such as port failure, routing failure, the system failure.
For further guaranteeing professional reliability, second type of BAS Broadband Access Server can be uploaded to the business datum of self business control device and back up.Business control device receives and stores the business datum that second type of BAS Broadband Access Server uploaded; When determining second type of failed server of existence; Business datum according to storage is determined all the other at least one second type of BAS Broadband Access Servers, and the business datum of second type of failed server of storage is sent to all the other at least one second type of BAS Broadband Access Servers of determining.
Describe with a practical implementation, in this example, four second type of BAS Broadband Access Servers carrying out same protocol of business control device control are respectively BRAS3, BRAS4, BRAS5, BRAS6 at present:
