But the failure that may occur in view of link between transport network node and interruption, can also calculate a route stand-by, so as to
Original link used can turn data when there are the failures such as breakpoint to be transmitted by route stand-by, it is ensured that the company of data transfer
Continuous property and High Availabitity.
All kinds of algorithms of the selection of current backup path based on mathematics, including in view of backup path and the weight of original route
Folded degree, to ensure the availability of backup path.
Above-mentioned all kinds of algorithms consider the route and route stand-by situation of single transmission requirement in overall network, or even are also contemplated for
To the performance issue of route stand-by, but fail to consider overall network condition：
1) there is a situation where multiple paths and multiple backup paths in network, some link downs are likely to result in a plurality of standby
Part route is enabled simultaneously.
2) transmittability between nodes has the upper limit, that is to say, that has bandwidth maximum load, individually sees one
The maximum load that individual route stand-by meets path transmission is required, but one or more backup path and unborn route
Superposition whether over burdening
It can see by the description of above mentioned problem, multiple backup paths come into force and may occur network local link and go out simultaneously
Now exceed the situation of maximum load so that network can not meet or can only partly meet the demand of route.
So, see network and routing condition without of overall importance, simply individually calculate a route and its backup road
By, it is impossible to the data transfer demands of global network are met, backup path can not necessarily play a role, suddenly needed at present a set of
The method of assessment, helps to evaluate the quality of route stand-by, and then further correct and optimize the selection of route stand-by.

Brief description of the drawings
Fig. 1 is the inventive method flow chart.
Embodiment
The present invention is described in further details with reference to the accompanying drawings and examples.
As shown in figure 1, appraisal procedure of the present invention comprises the following steps：
A：Obtain all global network states related to route stand-by；
B：The lower situation for being possible to interrupt of global network is calculated, and the load of corresponding route stand-by is scored；
C：Its sending probability is calculated for every kind of path disruption situation of route stand-by, weight is converted to；
D：By the load scoring calculated in step B Weight summation corresponding with step C, global route stand-by is obtained
Assessment fraction.
E：Global optimum's route backup scheme is obtained according to fraction is assessed.Such as, 1 can be obtained most according to fraction is assessed
Used when excellent route stand-by is for node interrupts, the route stand-by of one to two suboptimums can also be obtained for selecting according to fraction is assessed
Select.It is dynamic change that this, which assesses fraction, it is to avoid interrupted when a certain node is sent, other networks all select the route stand-by to cause
The situation that the route stand-by is blocked, is estimated as starting point from global network, effectively prevent one of route stand-by
Load excessive, influences network, causes network speed slow or delay situation.
Specifically, as one embodiment of the present of invention, the preferred SDN (Software of network of the invention
Defined Network, software defined network), network therein is made up of several line nodes, is easy to the acquisition of data
And the management and control of network.
In step, the global network state includes network wide parameters, the whole network route and route stand-by information.
The network wide parameters include global network and constituted, and the network constitutes the number of nodes M for including global network, section
The quantity N of link between point, the sequence number of link is respectively 1 to arrive N, and all adjacent node paths provide bandwidth, delay, every
The bandwidth application of route, actual bandwidth.
The present invention is further improved, described the whole network route and route stand-by information include after node interrupts, it is necessary to by
Link and corresponding routing overhead, the routing overhead include actual max load and current routing overhead.
The present invention is further improved, in stepb, as wherein n ... in N number of link in route stand-by, the link such as t
During interruption, (n ..., calculation formula t) is by the load scoring F of the route stand-by of startup and other routed path networks：
Wherein, Lx theoretical duties：The network load that link x should be provided when normal；
Lx actual max loads：The network load that link x can currently be provided, the actual max load when this link down
For 0；The current routing overheads of Lx：The load summation of the current route lines by link x, including because of certain link down through this chain
The route stand-by that road passes through.
Now, the scoring of each link load for one just or a negative numeral, scoring higher represents network state more
Good, it is bad that scoring lower (such as negative) then represents network state.
In step C, the probability of every kind of path disruption is calculated according to the service-level agreement SLA of each link, and is converted
For weight.SLA (Service Level Agreement, service-level agreement), is the available availability of this physical link
Service standard, generally close to 1 numeral, such as 99.9%, represent service time T in interrupt time span be no more than T × (1-
99.9%).Such as, serial number n link Ln SLA is θn, then link n interrupt probability calculation formula be：(1-θn)。
In step D, using the probability of link down as factor of influence, calculate the load effect interrupted within three links and comment
Point, and summation draws the assessment fraction of final route stand-by, wherein,
The load effect score calculation formula of route stand-by when one link n is interrupted is：
Both links n, m are while the load effect score calculation formula of route stand-by when interrupting is：
Three links n, m, p are while the load effect score calculation formula of route stand-by when interrupting is：
The assessment fraction R of the global route stand-by is：R=R1+R2+R3.
Due to the SLA of a general physical link>99.9%, that is, the probability interrupted is (1-SLA).Therefore when 4 chains
Interrupt simultaneous be changed to less than (0.001) in road4, i.e., less than part per trillion, its weight influences almost for overall scoring
Ignore, therefore the present invention does not consider further that the situation that the link of 4 and the above is interrupted simultaneously.
The present invention also provides a kind of assessment system for realizing appraisal procedure, including acquisition module：For obtain it is all with it is standby
The related global network state of part route；Computing module：For calculating the lower situation for being possible to interrupt of global network, and accordingly
Route stand-by load scoring；Weight computation module：Its transmission is calculated for every kind of path disruption situation for route stand-by
Probability, is converted to weight；Route stand-by evaluation module：Based on the load scoring for calculating computing module and weight computation module
The corresponding Weight summation calculated, obtains the assessment fraction of global route stand-by.
The present invention can calculate the quality of different route stand-bies, by complete by scoring global route stand-by
Office's route is adjusted and revised, and can different global routes be carried out with across comparison, so obtain it is relative meet apply net
The global route stand-by that network transmission needs.
Embodiment described above is the better embodiment of the present invention, not limits the specific of the present invention with this
Practical range, the scope of the present invention includes but is not limited to present embodiment, all equal according to the equivalence changes of the invention made
Within the scope of the present invention.
