Embodiment 1
[0040] figure 2 It is a schematic diagram of the implementation flow of the forwarding information state synchronization method provided by Embodiment 1 of the present invention. The execution body of this method is figure 1 The controller 101 shown in. see figure 2 As shown, the forwarding information state synchronization method provided in this embodiment includes the following steps:
[0041] Step S201 , when it is detected that the network forwarding device 102 has resumed connection, a state synchronization request is sent to the network forwarding device 102 , and the network forwarding device 102 is notified to re-set the aging time of its local flow table group table.
[0042] In this embodiment, when the controller 101 detects that the network forwarding device 102 resumes the openflow connection, it sends a state synchronization request to the network forwarding device 102, and notifies the network forwarding device 102 to reconnect its local flow The table gr...
Embodiment 2
[0063] image 3 It is a schematic diagram of the implementation flow of the method for synchronizing the state of forwarding information provided by Embodiment 2 of the present invention. The execution body of this method is figure 1 The network forwarding device 102 shown in . see image 3 As shown, the forwarding information state synchronization method provided in this embodiment may include the following steps:
[0064] Step S301 , when receiving the state synchronization request issued by the controller 101 , re-set the timeout aging time for the local flow table group table of the network forwarding device 102 according to the timeout aging time parameter issued by the controller 101 .
[0065] In this embodiment, the overtime aging time parameter may be carried in the state synchronization request, or the controller 101 may separately set an instruction with the timeout aging time after the state synchronization request is issued. The form is delivered to the networ...
Embodiment 3
[0081] Figure 4 It is a schematic structural diagram of the controller 101 provided in Embodiment 3 of the present invention. For convenience of description, only the parts related to this embodiment are shown.
[0082] see Figure 4 As shown, the controller 101 provided in this embodiment includes a memory 1011, a processor 1012, and a computer program 1013 stored on the memory 1011 and operable on the processor 1012, and the computer program 1013 is described by the When executed by the processor 1012, the steps of the method for synchronizing the state of the forwarding information described in the first embodiment above are implemented.
[0083] The controller 101 in this embodiment of the present invention has the same idea as the method for synchronizing the state of forwarding information in the first embodiment above. For the specific implementation process, please refer to the method embodiment for details, and the technical features in the method embodiment are co...
