Description
Technical Field
The present invention relates to the field of network communication technologies, and in particular, to a method and an apparatus for switching between a host and a standby based on a Virtual Switch Matrix (VSM) system.
Background
With the increasing scale of the network, the traffic in the network is more and more diverse, and the processing requirements for various network services are more and more, so that a frame type device is introduced into the network device. A main control board card and various service board cards can be inserted into one frame type device to process various network services, and more diverse service requirements are met. However, if a single frame device is abnormal, a serious fault of the whole network will occur, and a Virtual Switch Matrix (VSM) technology is further developed, that is, two frame devices are virtualized as one device, one is used as a main frame device (Master) and is responsible for managing the whole VSM system, the other is used as a standby frame device (Slave) and is a redundant backup, and when the Master is restarted, the Slave is switched to the main frame.
As traffic increases day by day, in order to alleviate bandwidth pressure of network devices, a link aggregation technology is generally used at present, multiple links are aggregated together to form a logical aggregated link, and a network device can perform aggregated link negotiation with a connected opposite-end network device to determine an active (active) port and an inactive (in-active) port, where the active port can participate in traffic forwarding and the in-active port is in a blocking state and does not participate in traffic offloading and forwarding. After receiving the traffic, the network device may first use an aggregation classification algorithm to select a port participating in forwarding from the active ports of the aggregation link, and then send the traffic through the selected port, thereby implementing an even distribution of the traffic on the network device.
The link aggregation technique may be employed in a VSM system, see fig. 1, where fig. 1 is a schematic diagram of the link aggregation technique used in a VSM system. The Master comprises a Master control board control-a, a service board func1, a service board func2 and a cascade board a, the Slave comprises a Master control board control-b, a service board func3, a service board func4 and a cascade board b, the Master and the Slave are connected through the cascade board a and the cascade board b, the cascade board a is provided with a cascade port a, the cascade board b is provided with a cascade port b, and links corresponding to a port 1 of the func1, a port 2 of the func2, a port 3 of the func3 and a port 4 of the func4 can form an aggregation link.
The main/standby switching method based on the VSM system comprises the following steps: initially, a control-a controls the aggregation link negotiation of the VSM system, and if it is detected that a major abnormality occurs in the main frame device and a restart is required, ports and board cards are cancelled one by one, that is, port 1 on cancellation func1, cancellation func1, port 2 on cancellation func2, cancellation func2, cancellation cascade port a and cascade board a are cancelled; after finding that the state of the cascading port b is closed, the control-b switches to the Master, meanwhile, the traffic sent to the func1 and the func2 is sent to the func3 and the func4, the control-b takes over the aggregation link negotiation, as the ports 1 and 2 are not in place, the active table only comprises the ports 3 and 4 at the moment, the active table is sent to the func3 and the func4, the outlets of the traffic sent to the func3 and the func4 are searched according to the active table, and the traffic is forwarded out.
In the active-standby switching process of the VSM system, since the active tables from the control-a restart to the final func3 and func4 are updated to the port 3 and the port 4, a series of processes are required in the middle, and the active tables checked by the traffic sent to the func3 and func4 include the port 1, the port 2, the port 3 and the port 4, during the time, when the egress is calculated according to the shunting of the active tables, a large amount of traffic is distributed to the port 1 and the port 2, and at this time, the port 1 and the port 2 may have been cancelled, and then the traffic distributed to the port 1 and the port 2 is discarded, so that a large amount of packet loss is caused, and network fluctuation is caused.

In order to solve the above problem, an embodiment of the present invention provides a method for switching between a main standby mode and a standby mode based on a VSM system, so as to avoid packet loss and network fluctuation. Referring to fig. 2, fig. 2 is a flowchart of a main-standby switching method based on a VSM system shown in this application, where the VSM system includes a first frame device and a second frame device, the first frame device includes a first main control board, at least one first service board and a first cascade board, the second frame device includes a second main control board, at least one second service board and a second cascade board, a first cascade port of the first cascade board is connected to a second cascade port of the second cascade board, a port of the at least one first service board and a port of the at least one second service board form a aggregation link, the first frame device is used as the main frame device, and the second frame device is used as the standby frame device. The number of the first service board cards and the number of the second service board cards may be set according to actual needs, and when both the number of the first service board cards and the number of the second service board cards are 2, the structure of the VSM system is shown in fig. 1. The method is applied to a first main control board card, and comprises the following steps:
s21: and after detecting that the first frame type equipment needs to be restarted, performing aggregated link negotiation with an opposite-end VSM system connected with the VSM system to obtain each first activated port except for the port of the at least one first service board card.
When a Central Processing Unit (CPU) abnormality or the like occurs in the first frame device, the first frame device needs to be restarted. When the first main control board card detects that the first frame device needs to be restarted, the first main control board card first needs to perform link aggregation negotiation again with the opposite-end VSM system connected to the VSM system to obtain activated ports other than the port of at least one service board card, that is, each port still activated after the main/standby switching of the VSM system, and these ports may be defined as the first activated port.
S22: and updating a first activation port table corresponding to the aggregation link according to each first activation port.
The first active port is a port still activated after the active-standby switching of the VSM system, and therefore, an active port table corresponding to the aggregation link may be updated according to the first active port, and the active port table may be defined as the first active port table.
S23: and sending the first activation port table to at least one second service board card so that the at least one second service board card forwards the message according to the first activation port table.
And the standby frame type equipment can normally work in the process of restarting the main frame type equipment, so that the latest first activated port table is issued to the at least one second service board card, and the at least one second service board card is ensured to forward the message according to the first activated port table.
S24: and performing active-standby switching with the second frame type device, so that after the second frame type device is switched to be the main frame type device, performing aggregated link negotiation with the opposite-end VSM system to obtain each second activated port, and updating the first activated port table according to the second activated ports.
And after the first main control board card issues the latest first activated port table, executing the process of main-standby switching with the second frame type equipment.
As can be seen from the above technical solutions, after detecting that the main frame device needs to be restarted, the main control board card of the main frame device performs a link aggregation negotiation with the opposite VSM system connected to the VSM system to update the first active port table corresponding to the link aggregation, where the first active port table does not include a port of at least one first service board card, and issues the first active port table to at least one second service board card of the standby frame device, and then performs a standby-to-standby switch with the standby frame device, so as to ensure that the at least one second service board card forwards a message according to the updated first active port table, thereby ensuring that the at least one second service board card forwards the message according to the accurate first active port table in the process of the standby-to-standby switch of the VSM system, and avoiding packet loss and network fluctuation.
Specifically, in the above S21, performing aggregated link negotiation with the opposite-end VSM system connected to the VSM system to obtain each first activated port except for the port of the at least one first service board specifically includes:
determining each port of at least one first service board card included in an aggregation link;
updating operation identification in a Link Aggregation Control Protocol (LACP) message periodically sent through each port to a set value, and then sending the set value to an opposite-end VSM system, so that the opposite-end VSM system selects an activated port in an aggregation link according to the received LACP message and then updates a second activated port table corresponding to the aggregation link;
and acquiring ports except for the port of at least one first service board card in the current activated ports in the aggregation link to obtain each first activated port.
Generally, ports at two ends of each member link in an aggregated link periodically send Link Aggregation Control Protocol (LACP) messages to notify state information of each port, so when an opposite-end VSM system connected to the VSM system performs aggregated link negotiation, because a first frame device needs to be restarted, a port of at least one first service board in the first frame device in the aggregated link will be in an inactive state, and therefore when the opposite-end VSM system performs active port election, a corresponding port needs to be elected as an inactive port, at this time, each port of at least one first service board included in the aggregated link may be first determined, an operation identifier in an LACP message periodically sent through each port is updated to a set value and then sent to the opposite-end VSM system, and when the opposite-end VSM system elects according to a received LACP message, the ports are elected as inactive ports, then a second active port table corresponding to the aggregated link is updated according to the active ports in the aggregated link, the second active port table represents an active port table of an opposite-end VSM system, and the VSM system also obtains the ports except for the port of at least one first service board card in the current active ports in the aggregated link to obtain each first active port.
The operation identifier (alert _ key) in the LACP indicates the home duplex rate, which is an influence factor for selecting an activated port, and the value of the operation identifier may be set to a set value, for example, may be set to 0, which may indicate that the home duplex rate is 0, so that the VSM system at the opposite end does not select the port as the activated port. In an optional implementation manner, the management identifier (admin _ key) of the LACP packet may also be set to 1, which marks that the member port of the local aggregation link is in a new active/standby switching method.
Specifically, the updating of the first activation port table corresponding to the aggregation link according to each first activation port in S22 specifically includes:
emptying the first active port table;
the port identification of each first active port is added to the first active port table.
For example, each active port may be compared with the first active port table one by one, added, and then the other ports except for each active port in the first active port table are deleted, so that the first active port table may be updated. There are many other implementations, which are not described in detail herein.
Specifically, the performing active-standby switching with the second frame device in S24, so that after the second frame device is switched to the main frame device, performing aggregated link negotiation with the opposite-end VSM system to obtain each second active port, and updating the first active port table according to the second active port, where the implementation process specifically includes:
and logging off at least one first service board card and a port thereof, a first cascade board card and a first cascade port, so that the second frame type equipment is switched to main frame type equipment after detecting that the state of the second cascade port is closed, performing aggregated link negotiation with an opposite terminal VSM system again to obtain each second activated port, updating the first activated port table according to each second activated port, and determining that the first activated port table is the same as the current activated port table of at least one second service board, and then determining to complete the main-standby switching of the VSM system.
It should be noted that, since the first active port table is already updated before the first frame device is restarted, and after the second frame device is switched to the main frame device, the port identifier included in the first active port table obtained by performing link aggregation negotiation with the opposite-end VSM system is completely consistent with the port identifier included in the first active port table updated before the first frame device is restarted, the second frame device does not need to issue the first active port table again.
