Specific implementation mode
To make the object, technical solutions and advantages of the present invention express to be more clearly understood, below in conjunction with the accompanying drawings and specifically
The present invention is further described in more detail for embodiment.
In embodiments of the present invention, the speed of the bit error rate is detected, and then network link is determined rapidly based on the bit error rate
Credit rating.Secondly, the overhead value of network link is updated by the credit rating of network link.Service message is switched seamlessly to
Network link in minimal-overhead total value respective path.To ensure that the safety of handover network link.
It is the method flow schematic diagram of handover network link in the embodiment of the present invention referring to Fig. 1, the present embodiment can be applied
In the router of bearer network, specifically include：
101, the network link bit error rate is detected.
Error code refers to that the signal that communication equipment receives bit error occurs compared with when the signal is sent out.Usually embody
It is malfunctioned according to the data packet that cyclic redundancy check (CRC) checking algorithm detects for equipment.Due to inevitable aging circuit,
Reasons, the error codes such as light path shake cannot be avoided fundamentally, and error accumulation may lead to business network element to a certain extent
Stop service or reduces the serious problems such as the grade of service.
The bit error rate=(error code in transmission/gross yards transmitted) * 100%.
The network link bit error rate is detected, the network link bit error rate can be periodically detected, can also be according to triggering message
Detect the network link bit error rate.
102, the credit rating of network link is determined based on the bit error rate, low-quality threshold value and high-quality threshold value.
Low-quality threshold value is equal to A*10-B, A is greater than equal to 1 and the integer less than or equal to 9, B be greater than equal to 1 and less than etc.
In 7 integer.
High-quality threshold value is equal to C*10-D, C is greater than equal to 1 and the integer less than or equal to 9, D be greater than equal to 1 and less than etc.
In 7 integer.
Low-quality threshold value is being set and when high-quality threshold value, it is contemplated that timely service switchover and can be kept away when business is damaged
Exempt between two threshold values distance it is too small caused by " pingpang handoff " caused by business frequent switching.
Existing network pattern test result is consistent with 3GPP standards, and when packet loss is 1.98%, voice communication is without noise；
When packet loss is higher than 3% (test is 3.58%), voice communication can experience slight noise；And as network link is continuous
Deterioration, downward trend is also presented in speech quality, when packet loss reaches 10% or so, cannot carry out normal talking.
From the point of view of repeatedly being tested according to existing network, the impacted critical value of voice service, i.e. A is equal to 4, B and is equal to 2, low-quality
Threshold value is equal to 4*10-2, link packet drop rate is 3% or so at this time；That is C is equal to 3, D and is equal to 3, and high-quality threshold value is equal to 3*10-3, at this time
Link packet drop rate is 0.2% or so.
It is the basic demand being arranged for speech business link error rates threshold value above.In practical applications, base can be compared
Plinth setting value is sensitive, such as：A is equal to 1, B and is equal to 3；C is equal to 1, D and is equal to 4.
For bearing data service because sensibility is less than speech business, setting value is slightly below speech business：That is A is equal to equal to 1, B
2；C is equal to 1, D and is equal to 3.
The bit error rate is more than low-quality threshold value, it is determined that the credit rating of network link is low-quality.
The bit error rate is less than or equal to low-quality threshold value and is more than high-quality threshold value, it is determined that the credit rating of network link is medium.
The bit error rate is less than or equal to high-quality threshold value, it is determined that the credit rating of network link is high-quality.
It can determine the credit rating of network link rapidly according to the bit error rate, low-quality threshold value and high-quality threshold value.

Determine that the credit rating purpose of network link is to update the overhead value of network link.Overhead value is evaluation lattice chain
The excellent numerical value in road.Network link initial cost value is arranged according to system and real network state.Overhead value is smaller, then says
The quality of bright network link is higher；Correspondingly, overhead value is bigger, then illustrate that the quality of network link is poorer.
The credit rating of network link be low-quality, by the overhead value of network link be updated to network link initial cost value and
The sum of low-quality overhead value.That is, being low-quality in the credit rating for determining network link, then in network link initial cost value

The sum of matter overhead value.
The credit rating of network link is high-quality, and the overhead value of network link is updated to network link initial cost value.
It is to be understood that when the credit rating of network link is high-quality, the overhead value of network link is always that network link is initially opened
Pin value.
When the credit rating of network link is increased to high-quality by low-quality, the overhead value of network link is updated to lattice chain
Road initial cost value；Network link credit rating by it is medium be increased to high-quality when, the overhead value of network link is updated to
Network link initial cost value.It is to be understood that increased low-quality overhead value removal when by low-quality, by the overhead value of network link
It is updated to network link initial cost value.
Under low-quality, medium and high-quality three kinds of credit ratings, the overhead value of network link is determined respectively.
104, by the network link in service switching to minimal-overhead total value respective path, expense total value is equal to institute in path
There is the sum of the overhead value of network link.
Include one or one or more network path in the paths.When path includes a network path, every network
Link has overhead value, can be by service switching to the network link of overhead value minimum.Include one or more path in the paths
When, need computing cost total value.Expense total value is equal to the sum of the overhead value of all-network link in path.Then, business is cut
The network link in minimal-overhead total value respective path is shifted to,
I.e. by service switching to top-quality network link.And original network link is as reserve link.In business
It is currently located network link quality decline, then again depending on overhead value handoff links.Promote the preferred overhead value total value of business smaller
Path, portless/link state changes in handoff procedure.Data message will not be lost, ensures the available of business to greatest extent
Property and continuity.
In addition, in network link one end (such as：Router) know updated overhead value, then it can will be after update
Overhead value be sent to the other end of network link.In this way, opposite equip. can also know the overhead value of place network link.
