Technical Field
The present application relates to the field of network communication technologies, and in particular, to a method and an apparatus for switching between a master device and a slave device.
Background
The multi-machine backup function can ensure that the user service is not interrupted under the condition that the key service node has a single point fault. After the multi-machine backup function is configured, the main equipment backs up locally generated dynamic service information to the standby equipment in real time by using a service data backup channel established by the service. When the main equipment fails, the standby equipment can replace the main equipment to work. Because the backup service information exists on the standby equipment, the user who has been on line does not need to dial again, the charging and authorization information is not lost, the service of the user is not interrupted, and the reliability of the network is improved.
However, in the existing multi-machine backup scheme, when the active device reboots in response to the reboot command, the standby device needs to sense the reboot of the active device through a Virtual Router Redundancy Protocol (VRRP) Protocol or a Bidirectional Forwarding Detection (BFD) linkage VRRP, so as to perform active-standby switching, and during the active-standby switching, flow loss may occur.

Detailed Description
In order to make those skilled in the art better understand the technical solution in the embodiment of the present application, first, a rule to be followed by a master device and a slave device in a multi-machine backup networking supporting a VRRP protocol is briefly described below.
1. The main equipment issues a VRRP virtual MAC address, and the standby equipment cannot issue the VRRP virtual MAC address;
2. the main equipment sends VRRP protocol messages at regular time and refreshes MAC table entries of the two-layer switch, so that the flow of a user access network can find an outlet interface according to the refreshed MAC table entries for forwarding;
3. the primary device issues a route, and the standby device does not issue a route.
In order to make the aforementioned objects, features and advantages of the embodiments of the present application more comprehensible, embodiments of the present application are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, a schematic diagram of a state machine in a multi-machine Backup networking supporting a VRRP protocol according to an embodiment of the present disclosure is shown in fig. 1, where in the embodiment of the present disclosure, a Proxy Master-Proxy state machine is newly added on the basis of an original Master state machine (Master), a Backup state machine (Backup) and an initial (initial) state machine; wherein:
when the multi-machine Backup networking is initialized to operate, each access device is in an Initialize state, main devices are selected in an competition mode, the access devices selected in the competition mode as the main devices are switched to a Master state from the Initialize state, and the rest access devices are switched to a Backup state from the Initialize state;
when receiving a VRRP notification message (herein referred to as a first type VRRP notification message) sent by a Master device and used for indicating that the Master device is switched to a Proxy Master device state, a standby device switches to a Master-Proxy state;
when the main equipment receives a restart instruction, a first type VRRP notification message is sent, and when the main equipment is restarted, the Master state is switched to the Backup state, and the Backup state is switched to the Master state after the preset delay preemption time; when the access equipment in the Master-Proxy state receives a VRRP protocol message sent by the main equipment, the Master-Proxy state is switched to the Backup state;
when the access equipment in any state has equipment or port failure, the access equipment is switched to the Initialize state;
when the Master device fails, the Master device is switched to the initialization state from the Master state, the standby device reselects a new Master device, and the new Master device is switched to the Master state from the Backup state.
Referring to fig. 2, a schematic flow chart of a main/standby switching method provided in an embodiment of the present application is shown, where the main/standby switching method may be applied to an Access device in a multi-computer backup networking supporting a VRRP protocol, such as a BRAS (Broadband Remote Access Server), as shown in fig. 2, the main/standby switching method may include the following steps:
step 201, if the access device is a master device and receives a restart instruction, sending a first type VRRP notification message to a standby device; and if the confirmation response message is received or the confirmation response message is not received within the preset time length, restarting.
In this embodiment of the application, if the active device receives a restart instruction, for example, if the active device performs version upgrade, the active device needs to send a first type VRRP notification message to the standby device before restarting, and restart the active device when receiving an acknowledgement message (such as an ACK (acknowledgement) message) sent by the standby device or when not receiving the acknowledgement message within a preset time length.
After the master device receives the first type of VRRP advertisement message and before restarting, the master device needs to cancel the issued VRRP virtual MAC Address and the issued route, and refuse to respond to the received free ARP (Address Resolution Protocol) message and the VRRP Protocol message, and does not send the VRRP Protocol message according to the mechanism of the original master device.
In this embodiment, when receiving the first type VRRP notification message sent by the active device, the standby device may return an acknowledgement message to the active device, and switch to the proxy active device state.
It should be noted that, in this embodiment of the present application, because multiple backup devices may exist in a multi-machine backup networking, and only one proxy main device needs to exist in the networking, if multiple backup devices exist, and the backup devices receive a first type VRRP notification message sent by a main device, then the multiple backup devices need to perform proxy main device election, and specific implementation thereof may refer to an implementation manner in which, when a main device in an existing multi-machine backup networking fails, a backup device performs new main device election, which is not described in detail in this embodiment of the present application.
Correspondingly, in one embodiment of the present application, if the access device is a standby device and receives the first type VRRP advertisement packet, before the switching to the proxy master device state, the method further includes:
if other standby equipment exists, carrying out agent main equipment election with other standby equipment;
if the access device is elected as the proxy main device, determining to execute the step of switching to the proxy main device state.
In this embodiment, when receiving a first type VRRP protocol packet sent by a primary device, a standby device needs to first determine whether there are other standby devices, and if there are other standby devices, the standby device needs to perform proxy master device election with the other standby devices, and when itself is elected as a proxy master device, it is switched to a proxy master device state.
If the standby equipment determines that other standby equipment does not exist, the standby equipment is directly switched to the proxy main equipment state.
In the embodiment of the application, after the access device is switched from the standby device state to the proxy master device state, the relevant processing of the master device needs to be executed, that is, a VRRP MAC address is issued, routing information is issued, and a VRRP protocol message is sent at regular time; when the two-layer switch receives the VRRP protocol message sent by the proxy main equipment, the two-layer switch can refresh the local MAC table entry.
It can be seen that, in the flow of the method shown in fig. 2, when the active device receives a restart instruction, before the restart, the active device actively triggers the standby device to switch to the proxy master device state, and the access device in the proxy master device state issues the VRRP MAC address, issues the routing information, and sends the VRRP protocol packet at a fixed time.
Further, in one embodiment of the present application, after the restarting in step 201, the method may further include:
if the restart is completed, switching to a standby equipment state;
if receiving the VRRP protocol message and determining that the priority of the access equipment is higher than the priority carried in the VRRP protocol message, switching to the state of the main equipment after waiting for the preset delay preemption time.
In this embodiment, when the original master device is restarted, the original master device is first switched to the standby device state. Because the access device in the proxy master device state can send the VRRP protocol packet at regular time, the VRRP protocol packet sent by the access device in the proxy master device state can be received after the original master device is switched to the standby device state.
If the original master device is restarted and receives the VRRP protocol packet, the priority of the master device itself may be compared with the priority carried in the VRRP protocol packet (i.e., the priority of the access device in the proxy master device state). If the priority of the master device is higher than that carried in the VRRP protocol message, the original master device is switched from the standby device state to the master device state again.
After the original master device is switched from the standby device state to the master device state again, relevant processing operations of the master device are re-executed, such as sending a virtual VRRP MAC address, issuing a route, sending a VRRP protocol message at regular time, and the like.
Accordingly, in one implementation manner of this embodiment, after the switching to the proxy master device state in step 202, the method may further include:
if the VRRP protocol message is received and the priority of the access equipment is determined to be lower than the priority carried in the VRRP protocol message, the state of the standby equipment is switched.
In this embodiment, after the original master device is restarted and switched to the master device state again, the VRRP protocol packet is sent at regular time.
When the access device in the proxy master device state receives the VRRP protocol packet sent by the master device, the priority of the access device itself may be compared with the priority (priority of the master device) carried in the VRRP protocol packet. If the self priority is lower than the priority carried in the VRRP protocol message, the access equipment in the proxy main equipment state is switched to the standby equipment state from the proxy main equipment state.
If the access device is switched from the proxy main device state to the standby device state, the access device will withdraw the VRRP virtual MAC address issued by itself and the issued route.
In order to enable those skilled in the art to better understand the technical solutions provided in the embodiments of the present application, the following describes the technical solutions provided in the embodiments of the present application with reference to specific application scenarios.
Referring to fig. 3, a schematic diagram of an architecture of a specific application scenario provided in the embodiment of the present application is shown in fig. 3, in this embodiment, taking an access device as a BRAS device as an example, a BRAS a and a BRAS B form a dual-device hot standby. Suppose BRAS a is a primary device and BRAS B is a backup device.
Based on the application scenario shown in fig. 3, the implementation flow of the active/standby switching scheme provided in the embodiment of the present invention is as follows:
1. the BRAS a receives the restart instruction, and at this time, the BRAS a does not directly restart, but performs the following processing:
a. sending a first type VRRP notification message (called VRRP Master-Proxy message in the embodiment), waiting for BRAS B to reply an ACK message, and directly restarting if receiving the ACK message; if the ACK message replied by the BRAS B is not received in the continuous preset number (such as 3) sending periods, restarting is also carried out;
b. after sending VRRP Master-Proxy message, before restarting, BRAS A does not respond to the free ARP message received (avoid BRAS B sending free ARP conflict after switching to Master-Proxy state);
c. after sending the VRRP Master-Proxy message and before restarting, BRAS A does not send the VRRP protocol message at regular time (preventing from triggering and refreshing the MAC table entry of the two-layer switch) and does not respond to the received VRRP protocol message.
2. After receiving the VRRP Master-Proxy message, the BRAS B executes the following processing:
a. replying an ACK message, and switching to a Master-Proxy state;
b. issuing a VRRP virtual MAC address;
c. sending VRRP protocol message at fixed time, triggering and refreshing MAC table entry of the two-layer switch, so that the two-layer switch forwards the flow of a user side (namely Host A-C) to a network side to a BRAS B;
c. and issuing the route so that the traffic from the network side to the user side is forwarded through the BRAS B.
3. After the BRAS a is restarted, the state is switched to the Backup state, if a VRRP protocol message sent by a BRAS B is received, the priority of the BRAS a is compared with the priority carried in the VRRP protocol message (namely the priority of the BRAS B), and the priority of the BRAS a is found to be higher than the priority carried in the VRRP protocol message.
After BRAS a switches to Master status, the following processing is executed:
a. issuing a VRRP virtual MAC address;
b. issuing a route;
c. and sending a VRRP protocol message at regular time, and triggering and refreshing the MAC table entry of the two-layer switch so that the two-layer switch forwards the traffic from a user side (namely Host A-C) to a network side to the BRAS A.
4. The BRAS B receives the VRRP protocol message sent by the BRAS A, compares the self priority with the priority carried in the VRRP protocol message (the priority of the BRAS A), finds that the self priority is lower than the priority carried in the VRRP protocol message, and at the moment, the BRAS B is switched to a Backup state from a Master-proxy state.
After the BRAS B is switched from the Master-proxy state to the Backup state, the following processing is executed:
a. revoking the VRRP virtual MAC address issued by the user;
b. and canceling the route issuing.
As can be seen from the above description, in the embodiment of the present invention, if the access device is the active device and receives the restart instruction, the first type VRRP notification packet is sent to the standby device; if the confirmation response message is received, or the confirmation response message is not received within the preset time length, restarting is carried out; if the access equipment is standby equipment and receives the first type VRRP notification message, switching to the state of the proxy main equipment and returning a confirmation response message to the main equipment; if the access device is in the proxy main device state, issuing a VRRP MAC address, issuing routing information, and sending a VRRP protocol message at regular time.
