The initial data arrived is more complete, can preferably ensure ISSU compatibility.
ISSU supplementary modules are written in initial data by step S102, main control board.
In embodiments of the present invention, the equipment of ISSU supplementary modules 31 gets main control board in third party database
After 10 initial data, main control board 10 is auxiliary by initial data write-in ISSU by the database interface of third party database
Help module 31.
Step S103, ISSU supplementary module is according to the data difference between preset initial data version and target data version
It is different, initial data is updated, target data is obtained.
In embodiments of the present invention, the data difference between initial data version and target data version can be number of targets
According to version compared to the changed part of initial data version, for example, increase field, field length variation, delete field etc..
The data difference upgrades what the data structure in front and back version was determined according to ISSU, and in advance in ISSU supplementary modules 31
In be configured so that initial data can be updated to target by ISSU supplementary modules 31 by the function of third party database
Data, the target data meet the data characteristics of ISSU new versions.For example, ISSU upgrading before version in storage bgp neighbor letter
The partial data structure of breath is：
structstBgpPeer{
structin_addrs_addr；
shortsPeerFlag；
intiAclNumIn；
}；
Wherein, address style data s_addr：Indicate the neighbor address of bgp neighbor；Short categorical datas sPeerFlag：
Indicate the marker bit on bgp neighbor, the state for characterizing neighbours；Int categorical datas iAclNumIn：It indicates to match on bgp neighbor
The entrance ACL information set.
The partial data structure of storage bgp neighbor information is updated in version after ISSU upgradings：
structstBgpPeer{
structin_addrs_addr；
shortsPeerFlag；
intiAclNumIn；
intiAclNumOut；
}；
Wherein, int categorical datas iAclNumOut：Indicate the outlet ACL information configured on bgp neighbor.Obviously, data difference
It is different to have increased outlet ACL information newly for bgp neighbor, then only it need to increase a field iAclNumOut newly in ISSU supplementary modules 31,
And the initial value that the field is arranged is illegal ACL, it is ensured that the compatibility of the front and back data structure of ISSU upgradings.
In embodiments of the present invention, data difference may include in the first difference, the second difference and third difference at least
It is a kind of, wherein the first difference provides the field information to be increased of initial data version, and the second difference provides initial data version
Field information to be modified, third difference provide the field information to be deleted of initial data version, the first difference, the second difference and the
Three differences are determined all in accordance with the data structure in the front and back version of ISSU upgradings, are carried out in ISSU supplementary modules 31 in advance
Setting.
If data difference includes the first difference, ISSU supplementary modules 31 are according to preset initial data version and target
Field information to be increased is added to initial data, obtains target data by the first difference between versions of data.For example, data
Difference is that bgp neighbor has increased outlet ACL information newly, and has increased a field newly in advance in ISSU supplementary modules 31
IAclNumOut, and the initial value that the field is arranged is illegal ACL, then when ISSU is written in initial data by main control board 10
After supplementary module 31, ISSU supplementary modules 31 can add field iAclNumOut, the word in the bgp neighbor of initial data
The initial value of section is defaulted as illegal ACL.
If data difference includes the second difference, ISSU supplementary modules 31 are according to preset initial data version and target
The second difference between versions of data is modified to the field to be modified of initial data using field information to be modified, is obtained
Target data.For example, ISSU upgrading before version in storage bgp neighbor information partial data structure be：
structstBgpPeer{
structin_addrs_addr；
shortsPeerFlag；
intiAclNumIn；
}；
The partial data structure of storage bgp neighbor information is updated in version after ISSU upgradings：
structstBgpPeer{
structin_addrs_addr；
intsPeerFlag；
intiAclNumIn；
}；
Wherein, int categorical datas sPeerFlag：Indicate the marker bit on bgp neighbor, the state for characterizing neighbours.It is aobvious
So, data difference is that neighbor state is changed to int by bgp neighbor from short, has increased outlet ACL information newly, then only need to be in ISSU
The data type of sPeerFlag is changed to int types in supplementary module 31.When initial data is written main control board 10
After ISSU supplementary modules 31, ISSU supplementary modules 31 can be directly by the neighbor state of bgp neighbor in initial data from short
It is changed to int.
If data difference includes third difference, ISSU supplementary modules 31 are according to preset initial data version and target
Third difference between versions of data is deleted the field to be deleted of initial data using field information to be deleted, obtains number of targets
According to.For example, ISSU upgrading before version in storage bgp neighbor information partial data structure be：
structstBgpPeer{
structin_addrs_addr；
shortsPeerFlag；
intiAclNumIn；
intiAclNumOut；
}；
The partial data structure of storage bgp neighbor information is updated in version after ISSU upgradings：
structstBgpPeer{
structin_addrs_addr；
shortsPeerFlag；
intiAclNumIn；
}；
Obviously, data difference is that bgp neighbor deletes outlet ACL information, then need to only be deleted in ISSU supplementary modules 31
Field iAclNumOut.After supplementary module 31 ISSU are written in initial data by main control board 10, ISSU supplementary modules 31
Directly the field iAclNumOut of bgp neighbor in initial data can be deleted.
