After the VRRP function is started, the router in the backup group determines the main backup role of the router according to the priority, the router with the higher priority is the main router, and before the main router fails, the main router is kept working, and other routers do not work.
However, keeping only one master router operating in a backup group is prone to bandwidth waste.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A data transmission method and system according to an embodiment of the present invention will be described with reference to the drawings.
The VRRP protocol is used as a selection protocol, can avoid confusion caused by IP data flow failover, allows a host to use single-route equipment, and can still maintain the connectivity between routers under the condition that a first-hop router fails.
Fig. 1 is a working topology diagram of a conventional VRRP protocol, which is only described by taking an example that a backup group includes two routers. As shown in fig. 1, the working process of the VRRP protocol is described as follows:
(1) starting a VRRP protocol: after the router 1 and the router 2 start the VRRP function, the main and standby roles of the routers are determined according to the priority.
(2) Selecting the main and standby roles: the router with high priority becomes the main router, and the router with low priority becomes the standby router.
(3) And (3) periodically notifying: the master router sends VRRP notification messages to the standby router periodically to inform the standby router in the backup group that the standby router is in a normal working state; the standby router starts a timer function to judge whether an advertisement message is received within a timing time limit.
(4) And (3) fault treatment: if the VRRP notification message sent by the main router is not received after the timing range of the standby router is exceeded, the main router is considered to be out of order, and the standby router elects to be the main router at the moment and sends the VRRP notification message to the outside.
When the existing VRRP protocol works, only the router 1 in the active state can work, but the router 2 in the standby state does not work, and in the example shown in fig. 1, the work flow can only be: the router 3< - > router 1< - > server, and the router 3< - > router 2< - > server does not forward messages, which results in the waste of equipment bandwidth. If the bandwidth is to be increased, the capacity of the equipment must be expanded, two additional routers are needed, and the equipment cost is increased.
In view of the above problems, an embodiment of the present invention provides a data transmission method, which enables routers in a backup group to simultaneously operate as a master device, and increases bandwidth without increasing devices.
It should be noted that the following embodiments can be applied to the case that the backup group of the VRRP includes at least two routers, and for convenience of description and understanding, the following description only takes the case that the backup group includes only two routers as an example, but should not be taken as a limitation to the present invention.
Fig. 2 is a flowchart illustrating a data transmission method according to an embodiment of the present invention.
As shown in fig. 2, the data transmission method includes the following steps:
and S11, the first routing device and the second routing device carry out virtual routing redundancy protocol negotiation.
The backup group of the VRRP includes at least two routers, and the embodiment of the present invention is described only by including two routers in the backup group, which are respectively referred to as a first routing device and a second routing device. After the VRRP protocol is started, the first routing device and the second routing device need to negotiate.
S12, when the negotiation between the first routing device and the second routing device fails, the first routing device and the second routing device are both set to the master device state.
In this embodiment, when the negotiation between the first routing device and the second routing device fails, both the first routing device and the second routing device are set to the master device state.
And S13, the first routing device and the second routing device work simultaneously in the main device state.
In the VRRP backup group, the first routing equipment and the second routing equipment in the main equipment state work simultaneously.
For example, fig. 3 is a diagram of a VRRP protocol operating topology according to an embodiment of the present invention. As shown in fig. 3, both router 1 and router 2 are in the master state, and two links, router 3< - > router 1< - > server and router 3< - > router 2< - > server, work simultaneously. When one of the links fails, the other link still keeps a normal working state without reselecting the active routing equipment. The bandwidth can be increased under the condition that the equipment is not increased, and the backup function of the equipment is achieved.
In the data transmission method of this embodiment, a first routing device and a second routing device perform virtual routing redundancy protocol negotiation, and when the negotiation fails, both the first routing device and the second routing device are set to a master device state, and the first routing device and the second routing device operate simultaneously in the master device state. The routing equipment is set to be in the main equipment state and works simultaneously, so that the bandwidth can be increased, the equipment backup function is realized, and the network reliability is improved.
In order to set the first routing device and the second routing device in the main device state when the negotiation between the first routing device and the second routing device fails, embodiments of the present invention provide two ways of failing the negotiation between the first routing device and the second routing device.
As one possible implementation manner, as shown in fig. 4, on the basis of the embodiment shown in fig. 1, after step S11, the method further includes:
and S21, configuring different negotiation passwords for the first routing device and the second routing device respectively.
The negotiation password of the first routing equipment is a first password, the negotiation password of the second routing equipment is a second password, and the first password is different from the second password.
In the VRRP protocol, the routers at the two ends can be considered to be paired only when the negotiation passwords of the routers at the two ends are configured consistently, so that the negotiation can be successful; when the negotiation passwords are not consistent, the router negotiation at the two ends fails. Therefore, in this embodiment, different negotiation passwords may be configured for the first routing device and the second routing device, the first password is configured for the first routing device, the second password is configured for the second routing device, and the first password is different from the second password, so that the negotiation between the first routing device and the second routing device fails.
S22, the first routing device receives the first negotiation message sent by the second routing device, and the second routing device receives the second negotiation message sent by the first routing device.
The first negotiation message is encrypted by the second routing equipment by using a second password, and the second negotiation message is encrypted by the first routing equipment by using the first password.
In this embodiment, a negotiation packet may be set for the first routing device and the second routing device at both ends of the VRRP protocol, and the negotiation packet is encrypted by using the configured negotiation password.
Specifically, the negotiation packet of the second routing device may be encrypted by the second routing device using the second password, the encrypted negotiation packet is referred to as a first negotiation packet, the second routing device sends the first negotiation packet to the first routing device for negotiation, and the first routing device receives the first negotiation packet sent by the second routing device. The negotiation message of the first routing equipment is encrypted by the first routing equipment by using a first password, the encrypted negotiation message is called a second negotiation message, the second negotiation message is sent to the second routing equipment by the first routing equipment for negotiation, and the second negotiation message sent by the first routing equipment is received by the second routing equipment.
And S23, the first routing equipment decrypts the first negotiation message by using the first password, and the second routing equipment decrypts the second negotiation message by using the second password.
After the first routing equipment and the second routing equipment respectively receive the first negotiation message and the second negotiation message sent by the opposite side, the negotiation messages are decrypted by adopting respective negotiation passwords, namely the first routing equipment decrypts the received first negotiation messages by adopting the first password, and the second routing equipment decrypts the received second negotiation messages by adopting the second password. And when the first routing equipment and the second routing equipment both decrypt successfully, the negotiation between the first routing equipment and the second routing equipment is successful.
S24, when the decryption negotiation packet fails, it is determined that the negotiation between the first routing device and the second routing device fails.
It can be appreciated that for an encrypted file, it can only be opened by decrypting with the same password as the encrypted password. In this embodiment, since the first password is different from the second password, when the first routing device decrypts the first negotiation packet encrypted by the second password by using the first password, decryption fails; the second routing device also fails when decrypting the second negotiation packet encrypted by the first password using the second password. When the first routing device and the second routing device both fail to decrypt the negotiation packet, it may be determined that the negotiation between the first routing device and the second routing device fails.
In the data transmission method of this embodiment, different negotiation passwords are configured for the first routing device and the second routing device, the first routing device receives a first negotiation message sent by the second routing device, the second routing device receives a second negotiation message sent by the first routing device, the first routing device decrypts the first negotiation message by using the first password, the second routing device decrypts the second negotiation message by using the second password, and when the negotiation message is decrypted and failed, it is determined that the negotiation between the first routing device and the second routing device fails, which can lay a technical foundation for setting the first routing device and the second routing device in a main device state.
As another possible implementation manner, as shown in fig. 5, on the basis of the embodiment shown in fig. 1, the following steps may be further included after step S11:
s31, the first routing device receives the negotiation message sent by the second routing device, and the second routing device receives the negotiation message sent by the first routing device.
The routers in the VRRP backup group generally use the negotiation packet to perform task negotiation, in this embodiment, the first routing device may be configured to receive the negotiation packet sent by the second routing device, and the second routing device may receive the negotiation packet sent by the first routing device.
And S32, deleting the negotiation message after the first routing device and the second routing device receive the negotiation message.
S33, after the negotiation packet is deleted, it is determined that the negotiation between the first routing device and the second routing device fails.
In this embodiment, after the first routing device and the second routing device respectively receive the VRRP negotiation packet sent by the other party, the deletion of the VRRP negotiation packet, that is, the deletion of the VRRP negotiation packet, may be implemented in a software manner. Deleting the negotiation message is equivalent to discarding the negotiation message, and the negotiation cannot be carried out, so that the negotiation failure between the first routing equipment and the second routing equipment can be determined.
In the data transmission method of this embodiment, the first routing device receives the negotiation packet sent by the second routing device, and after the second routing device receives the negotiation packet sent by the first routing device, the negotiation packet is deleted, and then it is determined that the negotiation between the first routing device and the second routing device fails, which can lay a technical foundation for setting the first routing device and the second routing device in the main device state.
Fig. 6 is a flowchart illustrating a data transmission method according to another embodiment of the present invention.
As shown in fig. 6, the data transmission method may include the steps of:
and S41, the first routing device and the second routing device carry out virtual routing redundancy protocol negotiation.
S42, when the negotiation between the first routing device and the second routing device fails, the first routing device and the second routing device are both set to the master device state.
It should be noted that, in the description of the steps S41-S42 in the present invention, reference may be made to the description of the steps S11-S12 in the foregoing embodiment, and the implementation principle is similar, and therefore, the description is omitted here.
And S43, the first routing device and the second routing device work simultaneously in the main device state.
Specifically, the first routing device and the second routing device operate simultaneously in the main device state, and may include: the first routing device and the second routing device respectively receive the first data sent by the third routing device and send the first data to the server through respective links with the server.
That is, the first routing device and the second routing device, both in the master device state, have equal status, and both simultaneously receive the data sent by the third routing device and forward the received data to the server via the respective communication links. When one of the links fails, the other link can still keep working normally.
The topology diagram of the simultaneous operation of the first routing device and the second routing device can be seen in the aforementioned fig. 3, and will not be described herein too much.
The two links send data simultaneously, so that the backup function of the equipment can be achieved, the bandwidth is increased, and the reliability of data transmission is ensured.
S44, the server selects one link from two links between the server and the first and second routing devices as a target link.
When the server sends data through the first routing device and/or the second routing device, one link may be selected as a target link from two links between the server and the first routing device and/or the second routing device.
Specifically, the server may calculate a hash value of the two links through a hash algorithm, and select a target link from the two links based on the hash value.
In order to meet the network requirement of the server, at least two network cards are usually arranged in the server. Taking an example in which two network cards are arranged in a server, when the server connects a first routing device and a second routing device, both the two network cards in the server are configured in a binding (bond) mode, and are set to a dynamic link aggregation mode (i.e., a mode4 mode). Under the configuration, the server selects a target link based on a hash algorithm, the hash algorithm calculates the hash values of the two links according to the five-tuple (namely, the source IP address, the source port number, the protocol type, the destination IP address and the destination port number) of the message, and then the server selects the target link from the two links according to the hash values. Because the server only selects one transmission link through the hash algorithm, two network cards in the server respectively select different links to send data, and the purpose of doubling the bandwidth can be achieved.
S45, the server sends the second data to the third routing device through the destination link.
In this embodiment, after determining the target link by calculating the hash value of the link, the server may send the second data to the third routing device through the target link.
In the data transmission method of this embodiment, a first routing device and a second routing device perform virtual routing redundancy protocol negotiation, when the negotiation between the first routing device and the second routing device fails, both the first routing device and the second routing device are set to a main device state, the first routing device and the second routing device operate in the main device state at the same time, a server selects one link from two links between the first routing device and the server, the server selects the link as a target link, and the server sends second data to a third routing device through the target link. Therefore, the bandwidth can be increased, the device backup function is realized, and the network reliability is improved.
In order to implement the above embodiments, the present invention further provides a data transmission system.
Fig. 7 is a schematic structural diagram of a data transmission system according to an embodiment of the present invention.
As shown in fig. 7, the data transmission system 70 includes: a first routing device 710 and a second routing device 720. Wherein the content of the first and second substances,
the first routing device 710 is configured to perform a virtual routing redundancy protocol negotiation with the second routing device 720, set itself to a master device state when the negotiation fails, and operate simultaneously with the second routing device 720 in the master device state.
The second routing device 720 is configured to perform a virtual routing redundancy protocol negotiation with the first routing device 710, set itself to a master device state when the negotiation fails, and operate simultaneously with the first routing device 710 in the master device state.
When the negotiation between the first routing device 710 and the second routing device 720 fails, the first routing device 710 and the second routing device 720 are set to be in an active state and operate simultaneously, and for this reason, the embodiments of the present invention propose two methods for causing the negotiation between the first routing device 710 and the second routing device 720 to fail.
In one possible implementation manner, different negotiated passwords are configured for the first routing device 710 and the second routing device 720, where the negotiated password of the first routing device 710 is the first password, and the negotiated password of the second routing device 720 is the second password. At this time, the process of the present invention,
the first routing device 710 is configured to receive a first negotiation packet sent by the second routing device 720, decrypt the first negotiation packet with a first password, and determine that negotiation with the second routing device 720 fails when decryption of the first negotiation packet fails, where the first negotiation packet is encrypted by the second routing device 720 with a second password.
The second routing device 720 is configured to receive the second negotiation packet sent by the first routing device 710, decrypt the second negotiation packet with the second password, and determine that negotiation with the first routing device 710 fails when decryption of the first negotiation packet fails, where the second negotiation packet is encrypted by the first routing device 710 with the first password.
In another possible implementation manner, the first routing device 710 is further configured to receive a negotiation packet sent by the second routing device 720, delete the negotiation packet after receiving the negotiation packet, and determine that the negotiation with the second routing device 720 fails after deleting the negotiation packet.
The second routing device 720 is further configured to receive a negotiation packet sent by the first routing device 710, delete the negotiation packet after receiving the negotiation packet, and determine that the negotiation with the first routing device 710 fails after deleting the negotiation packet.

Wherein the content of the first and second substances,
a third routing device 730 for sending the first data to the first routing device 710 and the second routing device 720 simultaneously.
And the server 740 is configured to receive the first data sent by the first routing device 710 and the second routing device 720.
In this embodiment, the first routing device 710 is further configured to receive the first data and send the first data to the server 740 over a link with the server 740. The second routing device 720 is also configured to receive the first data and send the first data to the server 740 over a link with the server 740.
In this embodiment, after the negotiation between the first routing device 710 and the second routing device 720 fails, both the first routing device 710 and the second routing device 720 set themselves to be in the main device state, and operate simultaneously in the main device state. The third routing device 730 can simultaneously send the first data to be transmitted to the first routing device 710 and the second routing device 720, and simultaneously transmit the first data to the server 740 through the two links between the first routing device 710 and the server 740 and between the second routing device 720 and the server 740, so as to achieve the purposes of device backup and bandwidth increase.
Optionally, in a possible implementation manner of the embodiment of the present invention, when the server 740 needs to send data, one link may be selected from two links between the first routing device 710 and the server 740, and the two links are used as a target link, and the second data is sent to the third routing device 730 through the target link. When the server 740 selects the target link, the target link is selected from the two links based on the hash value by specifically calculating the hash values of the two links.
It should be noted that the foregoing explanation of the data transmission method embodiment is also applicable to the data transmission system of this embodiment, and the implementation principle thereof is similar, and is not described herein again.
