Below in conjunction with explanation accompanying drawing, the embodiment of the present invention is described.
A kind of data transmission procedure based on VRRP that Fig. 2 provides for the embodiment of the present invention, this process comprises the following steps:
Each edge node devices in S201: two private networks sets up the corresponding tunnel passing through public network.
When two private networks are communicated by public network, as shown in Figure 1, in order to reduce packet loss, improving the accuracy of transfer of data, between the edge node devices in embodiments of the present invention in two private networks, setting up the corresponding tunnel passing through public network.In order to realize the transmission of data, ensureing the stability of transfer of data, generally setting up the tunnel that two are passed through public network, connect these two edge node devices passing through the tunnel of public network in private network, be respectively primary node device and secondary node equipment.
The edge node devices of such as the first private network is PE1 and PE2, the edge node devices of the second private network is PE3 and PE4, then can set up the tunnel passing through public network between PE1 and PE3, the tunnel passing through public network is set up between PE2 and PE4, can certainly be between PE1 and PE4, set up the tunnel passing through public network, between PE2 and PE3, set up the tunnel passing through public network, each fringe node can only set up the tunnel that is passed through public network.This tunnel passing through public network is bidirectional tunnel.
Each edge node devices in S202: two private networks, based on VRRP message, elects primary node device.
After establishing the tunnel passing through public network between the edge node devices of private network, in order to reduce packet loss, improving the accuracy of transfer of data, in the edge node devices in two private networks, electing primary node device.Also be described with above-mentioned example, the edge node devices of the first private network is PE1 and PE2, and the edge node devices of the second private network is PE3 and PE4, after setting up tunnel, elects primary node device between PE1, PE2, PE3 and PE4.
S203: the primary node device elected, by the edge node devices transmission message of tunnel to opposite end, notifies that the edge node devices of this opposite end upgrades to primary node device.
After primary node device elects, if this primary node device is at the first private network, then another edge node devices of this first private network, is defined as secondary node equipment by self.In order to reduce packet loss, improve the accuracy of transfer of data, the edge node devices of this primary node device notice opposite end, tunnel also upgrades to primary node device in embodiments of the present invention, and self is defined as secondary node equipment by another edge node devices accordingly in this another private network.
The edge node devices of such as the first private network is PE1 and PE2, the edge node devices of the second private network is PE3 and PE4, then set up the tunnel passing through public network between PE1 and PE3, the tunnel passing through public network is set up between PE2 and PE4, in 4 edge node devices, elect PE1 is primary node device, self is defined as secondary node equipment by the PE2 in the first private network, PE1 upgrades to primary node device by Tunnel Notify PE3, and the PE4 in the second private network determines certainly as secondary node equipment.
The primary node device of S204: two private networks, according to the tunnel set up, carries out transfer of data.
In two private networks, establish the tunnel passing through public network, and elected primary node device, transfer of data can be carried out by primary node device based on this tunnel between two private networks.
In order to ensure that data pass through tunnel transmission, and distinguish by the data of tunnel transmission, and by the data of public network transmissions, can be defined in the form of the data transmitted in tunnel in embodiments of the present invention, this data format is as shown in table 1:
