Platform service Central Control Module 1 is used for division and the formation of control virtual processor 2, controls the work of each module, and the data of self-virtualizing processor form and export to by business interface the system/application system of each service node in the future simultaneously.
Below, will be by a more specifically example explanation:
With reference to figure 2 and 3, suppose that synthesis business platform of the present invention is connected with three service nodes, i.e. 1 system of hospital, 2 systems of hospital and appointment registration system.The business that its 1 system of institute of traditional Chinese medicine need to carry out with synthesis business platform is synchronously (the abbreviation Y1) of doctor's scheduling data; What 2 systems of hospital and synthesis business platform carried out is that medicine is paid by mails professional (being called for short Y2); What appointment registration system and synthesis business platform carried out is register traffic (being called for short Y3).Then, as shown in Figure 3, synthesis business platform inside should have platform service Central Control Module 1 and three virtual processors 2.Three corresponding business of also being responsible for processing successively 1 system of hospital, 2 systems of hospital and appointment registration system of virtual processor 2 difference.It is 1 system of the corresponding hospital of virtual processor A1; 2 systems of the corresponding hospital of virtual processor A2; The corresponding appointment registration system of virtual processor A3.Among the figure, the pseudo channel of each virtual processor 2 has a main pseudo channel 31, two 32 secondary pseudo channels.Always have 3 main pseudo channels 31 (being expressed as T1, T2, T3) and six 32 secondary pseudo channels (D1, D2, D3 ... D6).Suppose that the synchronous service of doctor's scheduling data, the service priority level at platform that medicine is paid business, register traffic by mails are respectively from high to low: Y2＞Y1＞Y3.Namely then platform carries out three kinds of traffic load balance principles and is:
At first traffic identification and identification module 6 identifications identify service data request and data from the service request of three service nodes simultaneously; Then business datum is cut apart module 5, is used for being divided into sub-services or subdata from service or the data of traffic identification and identification module.Dividing method can be divided into data according to various partitioning algorithms the packet of equal or unequal length.Each packet keeps original service identification.Channel assignment module is carried out the channel allocation of subdata according to distribution mechanism.Channel assignment module is divided sub-services or the data formation formation (the corresponding formation of each pseudo channel) to be allocated that respectively has sign, and is responsible for assigning to each pseudo channel according to subdata.Wherein, because the service priority level of platform is respectively from high to low: Y2＞Y1＞Y3, then the subdata of Y2 partly is assigned to formation corresponding to main pseudo channel T2; Remainder then priority allocation at secondary pseudo channel (D1, D2, D3 ... D6) front of queue; The subdata of Y1 partly is assigned in formation corresponding to main pseudo channel T1, remaining secondary pseudo channel (D1, D2, the D3 of being distributed in ... D6) in the middle of the formation; And the subdata of Y3 partly is assigned in formation corresponding to main pseudo channel T3, remaining secondary pseudo channel (D1, D2, the D3 of being distributed in ... D6) formation terminal (being illustrated in fig. 4 shown below).At first, virtual processor A2, virtual processor A1 and A3 are by channel (T2, D1, D2, D3 ... D6) data of processing Y2 are that the most of computing power of platform is professional for the treatment of Y2, virtual processor A1 processes Y1 data, virtual processor A3 partly by channel (T1) and processes the Y3 partial data by channel (T3) simultaneously, and namely the terrace part computing power is also being processed Y1, Y3 business simultaneously.The so on the one hand load of balanced synthesis business platform inside, simultaneously also the arrangement of science justice business, improved the processing power of platform integrated service and the speed of business experience.
