[0033] Exemplarily, when a user terminal device needs to communicate data with a target server, the user terminal device needs to send routing information and target data to the target server through communication nodes such as the user front-end device 11, the access subsystem 12, and the operator backbone network 13.

The current edge router can generate the first message information according to the target routing information, and send the first message information to the user front-end device 11. If the user front-end device 11 does not receive the first message information within the first preset time, it indicates that the network failure of the current edge router can be determined according to the target routing information and the routing table. Other edge routers associated with the next-hop gateway address of the user front-end device 11, and the target routing information and the target data are sent to the other edge routers. After receiving the target routing information, other edge routers can generate second message information according to the target routing information, send the second message information to the user front-end device 11, and determine the path from other edge routers to the target server according to the target routing information and the dynamic routing table, and then determine other core routers associated with the next-hop gateway address of other edge routers as the target other core routers. And send the target routing information and the target data to the target other core router. The second message information can be used to indicate that other edge routers have successfully received the target routing information.

The third message information can be used to indicate that the target other core routers have successfully received the target routing information. It can be achieved in the Internet access service business that even if a certain access platform fails, it will not affect the normal operation of the business, and it will not be felt by the user. The disaster backup function of the Internet access service business platform can be realized, which can reduce the economic losses caused by network interruptions and improve the user experience.

[0048] In this embodiment, optionally, the system further includes at least one transmission medium, the current edge router is connected to the other core routers through the transmission medium; the other edge routers are connected to the current core router through the transmission medium;

[0050] The target current core router is used to generate fourth message information according to the target routing information, and send the fourth message information to the other edge routers, and send the target routing information and the target data to the target operator backbone network 13.

[0051] Among them, this scheme can also connect the current edge router with other core routers through the transmission medium, and connect the current core router with other edge routers. Other edge routers can also determine the current core router associated with the next hop gateway address of other edge routers according to the target routing information and the dynamic routing table as the target current core router.

[0052] After receiving the target routing information, the target current core router can generate the fourth message information according to the target routing information, and send the fourth message information to other edge routers, and determine the target operator backbone network 13 associated with the next-hop gateway address of the target current core router according to the target routing information and the dynamic routing table, and send the target routing information and target data to the target operator backbone network 13. The fourth message information can be used to characterize that the target current core router has successfully received the target routing information. It can be achieved in the Internet access service business that even if a certain access platform fails, it will not affect the normal operation of the business, and it will not be felt by the user. The disaster backup function of the Internet access service business platform can be realized, which can reduce the economic losses caused by network interruption and improve the user experience.

[0053] In a feasible implementation manner, optionally, the current edge router is further configured to determine the target current core router according to the target routing information after sending the first message information to the user front-end device 11, and send the target routing information and the target data to the target current core router;

[0054] The target current core router is used to generate fifth message information according to the target routing information, and send the fifth message information to the current edge router;

[0055] The current edge router is further configured to send the target routing information and the target data to the target other core router via the transmission medium if the fifth message information is not received within a second preset time.

[0056] After sending the first message information to the user front-end device 11, the current edge router can also determine the current core router associated with the next-hop gateway address of the current edge router according to the target routing information and the dynamic routing table as the target current core router, and send the target routing information and target data to the target current core router.

[0057] The target current core router may generate fifth message information according to the target routing information, and send the fifth message information to the current edge router.

[0066] Among them, in this solution, the user front-end device 11 is connected to the current edge router and other edge routers through the Overlay tunnel network to achieve dual-active Overlay tunnel access. It can be achieved that in the Internet access service business, even if a certain access platform fails, it will not affect the normal operation of the business, and the user will not feel it. The disaster backup function of the Internet access service business platform can be realized, which can reduce the economic losses caused by network interruption and improve the user experience.

[0067] It should be noted that this solution can also provide a routing forwarding and data transmission strategy of target server → operator backbone network → core router → edge router → user front-end device → user terminal device. The implementation process can refer to the specific description in the previous steps.

[0068] In order to more clearly describe the technical solution of the present invention, Figure 2 As shown, the technical solution provided by the embodiment of the present invention can be as follows:

[0069] Step 1. Determine two data center rooms about 30 km apart to carry the network element equipment of the ISP dual-active and disaster recovery platform. The current access subsystem is the first node group, represented by PD-Area, and the other access subsystems are the second node group, represented by PX-Area. The two access subsystems are interconnected through bare optical fibers Fiber1 and Fiber2 to establish DCI channels. Fiber1 and Fiber2 must be interconnected through different routing pipes to ensure the redundancy of DCI interconnection channels.

[0070] Step 2: The network architecture connection design scheme for each area is as follows:

[0071] (1) PD-Area includes three core routers, denoted by PD1, PD2 and PD3. The three core routers are interconnected with ISP1, ISP2 and ISP3 through the STATIC routing protocol and the default route is to the operator backbone network. PD1, PD2, PD3 and two core switches PD-CORE1 and PD-CORE2 are interconnected through Layer 2. The three edge routers PD-PE1, PD-PE2 and PD-PE3 are mainly aggregation nodes for remote access users and are also interconnected with core switches PD-CORE1 and PD-CORE2 through Layer 2. PD-area forms a fully interconnected network.

[0072] (2) PX-Area also includes three core routers, represented by PX1, PX2, and PX3. The three core routers are interconnected with ISP1, ISP2, and ISP3 through the STATIC routing protocol, and the default route is to the operator backbone network. PX1, PX2, and PX3 are interconnected with the two core switches PX-CORE1 and PX-CORE2 through the second layer. The three edge routers PX-PE1, PX-PE2, and PX-PE3 are mainly used as aggregation nodes for remote user access platforms. They are also interconnected with the core switches PX-CORE1 and PX-CORE2 through the second layer. PX-Area forms a fully interconnected network.

[0073] (3) PX-Area and PD-Area are interconnected through two bare optical fibers Fiber1 and Fiber2 that are not piped. The capacity of the two bare optical fibers is initially designed to be 40 Gbps. 100 Gbps capacity is reserved for expansion according to subsequent needs. DCI1-PD and DCI2-PD respectively establish a Layer 2 VLAN connection with PD1, PD2, PD3, PD-PE1, PD-PE2, and PD-PE3. DCI1-PX and DCI2-PX of PX-Area respectively establish a Layer 2 VLAN connection with PX1, PX2, PX3, PX-PE1, PX-PE2, and PX-PE3. All devices in PD-Area and PX-area are connected through two bare optical fibers. Logically, a single regional network is formed.

[0074] Step 3: The OSPF dynamic routing design for the two subsystems is as follows:

[0075] (1) All the inline interfaces of the three-layer nodes are added to the backbone area of ​​OSPF. PX1, PX2, PX3, PD1, PD2, PD3 are interconnected with ISP1, ISP2, ISP3 through STATIC routing, and are connected to ISP1, ISP2, ISP3 through default routing. The default routing is sent down in OSPF of PX1 and PD1 to each aggregation node PD-PE1, PD-PE2, PD-PE3, PX-PE1, PX-PE2, PX-PE3.

[0076] (2) The default routes of edge routers PD-PE1, PD-PE2, PD-PE3, PX-PE1, PX-PE2, and PX-PE3 are automatically learned from nodes PD1 and PX1 to access other ISPs. Data is forwarded to the corresponding core node through source address-based policy routing, and then reaches the operator backbone network at the core node according to the default route.

[0077] (3) User front-end equipment is connected to the PD-PE and PX-PE nodes through the Overlay tunnel network to achieve active-active Overlay tunnel access. When a PD node fails, it is automatically redundant to the PX node. When a PX node fails, it is automatically redundant to the PD node. When a force majeure disaster occurs in the entire PX-Area computer room, the user is automatically redundant to the platform of the PD-Area computer room. Conversely, when a force majeure disaster occurs in the PD-Area computer room, the user access network is automatically redundant to the platform of the PX-Area computer room, thereby achieving active-active and disaster recovery Internet access.
