Description

Data traffic forwarding method and system

Technical Field

The present disclosure relates to the field of computer information processing, and in particular, to a data traffic forwarding method, system, electronic device, and computer readable medium.

Background

An Open Shortest Path First (OSPF) Protocol and a Virtual Router Redundancy (VRRP) Protocol are both common traffic forwarding protocols, and at present, OSPF is based on interfaces to establish neighbors and learn routes, so that OSPF must establish OSPF neighbors with two VRRP devices simultaneously in a networking environment of VRRP to ensure that OSPF of a standby device can normally communicate with an interconnection device when a failure occurs in a VRRP primary device.

In the existing scheme, if OSPF is used for three-layer forwarding in a VRRP networking and an interconnection device, the interconnection device must establish OSPF neighbors with a primary device and a standby device of the VRRP respectively. At this time, the interconnection device, the active device and the standby device all form an OSPF neighbor relationship. The routes issued by the interconnection device through the OSPF are advertised to the active device and the standby device, and the routes on the active and standby devices are also issued to two neighbors of the interconnection device through the OSPF. Therefore, any one of the three devices can learn the other two issued OSPF routes, and the route is an equivalent route, and the next hop is two neighboring interface addresses respectively. Therefore, route learning is disordered, the flow cannot be correctly forwarded, the standby equipment receives a large amount of flow which is originally destined for the main equipment, and the operation load and pressure of the standby equipment are increased.

Accordingly, there is a need for new data traffic forwarding methods, systems, electronic devices, and computer readable media that support both the OSPF protocol and the VRRP protocol.

In the scheme of the disclosure, only the active device of the VRRP and the interconnection device establish the OSPF neighbor under the OSPF protocol, and when the VRRP state is switched, the new active device can establish the neighbor with the interconnection device in time and can immediately disconnect the OSPF neighbor of the original active device and the interconnection device. In the scheme disclosed by the invention, the OSPF (open shortest path first) neighbor establishing mode only by the main equipment and the interconnection equipment well solves the problems of disordered route learning and incorrect traffic forwarding caused by the OSPF neighbor establishing mode by the three equipment.

It should be clearly understood that this disclosure describes how to make and use particular examples, but the principles of this disclosure are not limited to any details of these examples. Rather, these principles can be applied to many other embodiments based on the teachings of the present disclosure.

The data traffic forwarding method disclosed in the present disclosure may be implemented by a determining module, a notifying module, and an executing module, where the determining module, the notifying module, and the executing module may be disposed in the control device, or may be disposed in the primary device, the standby device, and the interconnection device, and the present disclosure is not limited thereto.

The judging module is used for judging whether an interface on the equipment starts OSPF and VRRP functions, adding the interface which simultaneously starts OSPF and VRRP functions into the judging list and recording the VRRP state of the interface;

the notification module is used for reading the VRRP state of the interfaces in the judgment list once every N seconds, notifying the execution module of the VRRP state of the interfaces, and immediately notifying the execution module if the VRRP state of the interfaces in the judgment list is changed. If the interface state is not changed within 3 times of N seconds, the execution module is not informed;

the execution module is used for receiving and processing the information of the notification module, and when the OSPF state of the interface with the VRRP state of 'Backup' sent by the notification module is set to 'Down' and the interface is stopped from sending the 'Hello' message and not processing the 'Hello' message received by the interface. When receiving the message that the VRRP state of the interface sent by the notification module is changed from 'Backup' to 'Master', restoring the interface to make the interface consistent with a normally enabled OSPF interface, and normally receiving and sending a 'Hello' message; when the VRRP state of the interface receiving the notification module is changed from 'Master' to 'Backup', the processing flow is consistent with the processing flow of the message of which the VRRP state of the interface receiving the notification module is 'Backup'. If the interface state is always 'Master', keeping the OSPF state of the interface unchanged.

The above modules are described in detail in turn.

Fig. 3 is a flow chart illustrating a method of data traffic forwarding according to another exemplary embodiment. The process 30 shown in fig. 3 is a detailed description of the determination module.

As shown in fig. 3, in S302, whether the interface turns OSPF on. The method comprises the steps of actively collecting interface information of the main equipment and the standby equipment, and judging whether the OSPF function is started by the interfaces of the main equipment and the standby equipment according to the collected information.

In S304, whether the interface turns on VRRP. If the OSPF function is started by the interface, continuously judging whether the VRRP function is started by the interface.

In S306, the judgment list is not added. If the OSPF function is not started by the interface, the interface is not directly added in the judgment list. If the interface only opens the OSPF function and does not open the VRRP function, the interface is not added in the judgment list.

In S308, a judgment list is added. If the interface starts both OSPF function and VRRP function, adding the interface into the judgment list and recording the VRRP state of the interface in the judgment list.

Furthermore, when the VRRP state of the interface added in the judgment list is changed, the judgment module can immediately update the judgment list. When an interface for starting OSPF function and VRRP function is added, the judging module will add the added interface into the judging list and record the VRRP state of the added interface. When the interface in the judgment list closes the OSPF or VRRP function, the judgment module deletes the interface in the judgment list immediately.

Fig. 4 is a flow chart illustrating a method of forwarding data traffic according to another exemplary embodiment. The flow 40 shown in FIG. 4 is a detailed description of the notification module.

As shown in fig. 4, in S402, whether the interface VRRP state changes within 3 preset times or not. And reading the VRRP state of the interfaces in the judgment list once every preset time (N seconds), and informing all the interfaces in the judgment list of the VRRP state to an execution module.

In S404, a notification message is generated. When the notification module finds and judges that the state of the VRRP in the interface in the list is changed, the notification module immediately notifies the execution module of the latest state of the VRRP in the interface.

Furthermore, when the notification module finds that the new interface exists in the determination module, the notification module immediately notifies the execution module of the VRRP state of the new interface.

Furthermore, when the notification module detects that the interface in the determination module is deleted, the notification module immediately notifies the execution module that the interface is an invalid interface.

In S406, no notification message is generated. And when the VRRP state of the interface in the list is judged to be unchanged within 3 times N seconds, the execution module is not informed.

Fig. 5 is a flow chart illustrating a method of data traffic forwarding according to another exemplary embodiment. The flow 50 shown in FIG. 5 is a detailed description of the execution module.

As shown in fig. 5, in S502, whether the state of the interface VRRP is Master or not is determined.

In S504, the interface state is kept unchanged. When the notification module is received to inform the VRRP state of the interface as "Master", the execution module keeps the original OSPF state of the interface from processing.

In S506, the interface OSPF state is set to down and sending of hello packets is stopped. When the notification module informs the interface that the VRRP state is changed from 'Master' to 'Backup', the execution module immediately sets the OSPF state of the interface to 'Down' and stops sending the interface 'Hello' message.

Further, when the notification module is received to notify that the interface status is "Backup", the execution module immediately sets the OSPF status of the interface to "Down" and stops sending the interface "Hello" message.

Furthermore, when the notification module informs the VRRP state of the interface to change from "Backup" to "Master", the execution module immediately cancels the state restriction on the OSPF of the interface and allows the interface to normally send and receive the "Hello" message.

Furthermore, when the notification module is received to inform that the interface is invalid, the initial state of the interface is directly recovered.

The data traffic forwarding method disclosed by the invention realizes the mode that OSPF supports VRRP networking by introducing the control equipment, so that OSPF only needs to establish a neighbor with the main equipment of VRRP, thereby solving the problems of disordered route learning, wrong traffic forwarding and increased load pressure of the standby equipment caused by the OSPF neighbor between VRRP main and standby equipment.

Claims

1. A data traffic forwarding method can be applied to a network supporting OSPF protocol and VRRP protocol, and is characterized by comprising the following steps:

acquiring the starting states of an OSPF protocol and a VRRP protocol of a main device and a standby device;

when both an OSPF protocol and a VRRP protocol are in an open state, generating a judgment list according to the current state of the active equipment and/or the standby equipment and the VRRP protocol thereof;

establishing a neighbor relation based on an OSPF protocol between main equipment and interconnection equipment based on a VRRP protocol;

determining a forwarding path based on the OSPF protocol of the active device to forward data traffic, and setting the OSPF protocol state of the standby device based on the VRRP protocol to be invalid;

reading the current state of the VRRP protocol of the judgment list at regular time, and generating state change information when the current state is inconsistent with the current state read last time;

when the VRRP state of the main equipment is switched, state setting is carried out according to the state change information and a preset strategy so as to cut off the neighbor relation between the main equipment and the interconnection equipment, and the standby equipment based on a VRRP protocol is started to establish the neighbor relation between the standby equipment and the interconnection equipment; and determining a forwarding path based on the OSPF protocol of the standby equipment for data traffic forwarding.

2. The method of claim 1, wherein when the VRRP state of the active device is switched, comprising:

and when the state change information is received, determining the VRRP state switching of the main equipment.

3. The method of claim 1, wherein performing state setting to cut off neighbor relations of the active device and the interconnect device according to the state change information and a preset policy comprises:

and when the interface state of the state change information is changed from active to standby, setting the OSPF protocol state of the active device as invalid.

4. The method of claim 1, wherein establishing the neighbor relationship of the standby device and the interconnect device comprises:

and setting the state according to the state change information and a preset strategy to establish the neighbor relation between the standby equipment and the interconnection equipment.

5. The method as claimed in claim 4, wherein performing state setting according to the state change information and a preset policy to establish a neighbor relationship between the standby device and the interconnection device comprises:

and when the interface state of the state change information is changed from standby to main, setting the OSPF protocol state of the standby equipment to be effective.

6. A data traffic forwarding system, comprising:

the main equipment supports VRRP protocol and OSPF protocol and is used for forwarding flow;

the standby equipment supports VRRP protocol and OSPF protocol and is used for forwarding flow;

the interconnection equipment is used for acquiring the open states of an OSPF protocol and a VRRP protocol of the main equipment and the standby equipment, generating a judgment list according to the current states of the main equipment and/or the standby equipment and the VRRP protocol thereof when both the OSPF protocol and the VRRP protocol are in the open states, establishing a neighbor relation based on the OSPF protocol with the main equipment or the standby equipment, determining a forwarding path based on the OSPF protocol of the main equipment to forward data traffic, and setting the OSPF protocol state of the standby equipment based on the VRRP protocol to be invalid;

and the control equipment is used for regularly reading the current state of the VRRP protocol in the judgment list, generating state change information when the current state is inconsistent with the current state read last time, setting the state according to the state change information and a preset strategy to cut off the neighbor relation between the main equipment and the interconnection equipment when the VRRP state of the main equipment is switched, establishing the neighbor relation between the standby equipment and the interconnection equipment based on the starting of the standby equipment of the VRRP protocol, and controlling the starting of the standby equipment to forward data traffic when the VRRP state of the main equipment is switched.
