It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.

Although a flowchart depicts operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently, or at the same time. Furthermore, the order of the operations may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example 1
Fig. 1a is a flowchart of a method for controlling the start of a switch according to an embodiment of the present invention, where the embodiment of the present invention is applicable to solving broadcast storm, avoiding blocking of network channels and ensuring normal forwarding of data messages, and the method may be performed by a device for controlling the start of a switch according to the embodiment of the present invention, where the device may be implemented in software and/or hardware, and may be generally integrated in a switch device.
As shown in fig. 1a, the method for controlling the startup of a switch according to the present embodiment is executed by a switch in a switch ring network, where the switch includes: the quick-start forwarding system and the main system, and the quick redundancy ring function of the switch opened in the switch ring network specifically comprises:
s110, after the switch is powered down and powered up again, a starting process of the quick start forwarding system and the main system is executed at the same time, wherein the starting speed of the quick start forwarding system is faster than that of the main system.
In this embodiment, each switch included in the switch ring network previously starts a fast start function, that is, when the switch is powered down and powered up again, the fast start forwarding system and the main system are started at the same time, the fast start forwarding system is fast in starting speed, a simple message forwarding processing process can be rapidly executed, when the main system is actually restarted, the fast start forwarding system hands over control rights, and the started main system is used for realizing the message forwarding processing process in the actual sense.
The quick start forwarding system is used for storing port configuration information of the switch, is high in starting speed and can be used for forwarding a received message based on comparison by a user.
The main system is used for processing all functional items of the switch, such as forwarding control of received messages, and the like, and the starting speed is slower.
It can be understood that after the switch in the switch ring network is powered down and powered up again, the quick start forwarding system and the main system in the switch also synchronously perform power up start, wherein each switch in the switch ring network starts the quick redundancy ring function.
As an alternative implementation mode, the quick start forwarding system is a single chip microcomputer, and the main system is a central processing unit of the switch.
In the embodiment of the invention, the fast start forwarding system may be a single chip with a memory, the main system may be a central processing unit (Central Processing Unit, CPU) in a switch with a switching chip, where the memory may be a nonvolatile memory such as FLASH, ROM, etc., and the switching chip may be a chip KD5660, etc., and the embodiment of the invention is not limited in this way. The quick start forwarding system and the main system can be connected through a bus and conduct data interaction.
S120, after the start-up is completed through the quick start forwarding system, each switching port in the switch is configured according to the locally stored port configuration information, and after the configuration is completed, forwarding control is performed on the received message.
The port configuration information is adapted to the port states of all ports set in the switch ring network before the switch is powered down.
The port configuration information refers to configuration items of each port of the switch, such as port states, after the configuration of a fast redundancy RING protocol (DT-RING) used in the switch RING network is validated.
The memory of the quick start forwarding system stores port configuration information of each exchange port in the switch in advance, after the quick start forwarding system is powered on and started, the locally stored port configuration information is read, for example, the port configuration information stored in the FLASH memory is read, then relevant registers in the exchange chip of the switch are configured according to the port configuration information, states of each exchange port are set, and after the port configuration information is configured, the quick start forwarding system can perform forwarding control on received messages, for example, two-layer forwarding or three-layer forwarding control on the received messages and the like.
It can be understood that, in the switch ring network formed by the switches, the ring protocol may be selected as the fast redundancy ring protocol, and each switch turns on the fast redundancy function in advance.
The basic principle of the fast redundancy ring protocol is as follows: designating a master switch and a slave switch in a switch ring network, and designating a master port and a slave port of the master switch, wherein the master port is in a forwarding state, and the master port of the master switch sends a rapid redundancy detection message, and the slave port detects whether the rapid redundancy ring detection message is received or not; if so, indicating that a logic loop exists in the current switch system, and setting a slave port of the master switch to be in a blocking (block) state to disconnect the logic loop; if not, the slave port of the master switch is set to be in a forwarding state so as to increase the forwarding path to the greatest extent. Therefore, the fast redundancy ring protocol is used in the switch ring network, so that the broadcast storm problem of the switch in the starting process can be effectively avoided, and the normal forwarding of the data message is ensured.
Optionally, the switch is a master switch in a switch ring network; after the quick start forwarding system completes the start, configuring each switch port in the switch according to the locally stored port configuration information may include: after the quick start forwarding system is started, the main port in the main switch is set to be in a forwarding state according to the locally stored port configuration information, and the slave port in the main switch is set to be in a blocking state.
The switch ring network comprises a plurality of switches, wherein the switches comprise a master switch and at least one slave switch, and the master switch comprises a master port and a slave port. When the fast redundancy ring protocol is used in the switch ring network, the main port of the main switch is set to be in a forwarding state, and the slave port is set to be in a blocking state, namely the port configuration information which is locally stored by the fast start forwarding system and corresponds to the main switch.
Correspondingly, when the quick start forwarding system configures the main switch according to the port configuration information, the main port in the main switch can be set to be in a forwarding state, and the slave port in the main switch is set to be in a blocking state, so that the logic loop in the whole switch ring network is ensured not to occur.
Optionally, the switch is a slave switch in the switch ring network; after the quick start forwarding system completes the start, configuring each switch port in the switch according to the locally stored port configuration information may include: after the quick start forwarding system is started, all ports in the slave switch are set to be in a forwarding state according to the locally stored port configuration information.
When the fast redundancy ring protocol is used in the ring network of the switch, all ports of the slave switch are set to be in a forwarding state, namely port configuration information which is locally stored by a quick start forwarding system corresponding to the slave switch, so that all ports in the slave switch can be set to be in a forwarding state when the quick start forwarding system configures the slave switch according to the port configuration information.
By way of example and not limitation, a case of 1 master switch and 4 slave switches is shown in fig. 1 b. Wherein, each switch is interconnected in turn to form a switch ring network. Alternatively, the number of slave exchanges is not limited to 4, but may be 1 or 5, etc. The main port of the main switch is set to be in a forward state, the slave ports are set to be in a block state, all ports of the 4 slave switches are set to be in a forward state, at the moment, a logic loop cannot appear in the whole switch ring network, the problem of broadcast storm of the switch in the starting process is solved, the blocking of a network channel is avoided, and the normal forwarding of a data message is ensured.
S130, after the starting is completed through the main system, taking over the control right of the quick start forwarding system to the switch, and forwarding and controlling the received message.
After the quick start forwarding system completes the configuration of each switching port in the switch, other configurations are not carried out on the switch, the control right of the switch is released, after the main system of the switch is electrified and started, the main system takes over the control right, the forwarding control is carried out on the received message, and at the moment, the starting control of the switch is completed.
As an optional implementation manner, after the control right of the switch by the quick start forwarding system is taken over after the start is completed by the main system, the method may further include:
reading a root port in the switch ring network through the main system according to a quick redundancy ring function configured by the main system; determining, by the host system, a role of a switch in the switch ring network according to whether each port in the switch includes the root port; executing a control protocol matched with the master switch in the fast redundancy ring protocol by the master system if the role of the switch is determined to be the master switch; and if the role of the switch is determined to be the slave switch by the master system, executing a control protocol matched with the slave switch in the fast redundancy ring protocol.
For a switch configured with the fast redundancy ring protocol, a root port in the entire switch ring network needs to be specified in advance, for example, in a KIEN6000 switch configured with the fast redundancy ring protocol, port 4 is specified as the root port. Therefore, after taking over the control right of the switch, the main system can read the root port in the switch ring network according to the quick redundancy ring protocol configured by the local, if the root port belongs to the port in the local switch, the switch is determined to be the main switch, and a control protocol matched with the main switch in the quick redundancy ring protocol is executed, namely, a quick redundancy detection message is sent through the main port at regular intervals, and whether the slave port receives the quick redundancy detection message is detected; if the root port does not belong to the port in the local switch, determining that the switch is a slave switch, and executing a control protocol matched with the slave switch in the fast redundancy ring protocol, namely forwarding the fast redundancy detection message.
In the technical scheme provided by the embodiment of the invention, after the switch in the switch ring network is powered down and is powered up again, the starting processes of the quick start forwarding system and the main system are simultaneously executed, each switching port in the switch is configured according to the port configuration information stored locally after the quick start forwarding system is started, the received message is subjected to forwarding control after the configuration is completed, the control right of the quick start forwarding system to the switch is taken over after the main system is started, the received message is subjected to forwarding control, and when the switch is started, each switching port in the switch can be configured according to the port configuration information stored in the quick start forwarding system, so that the problem of broadcast storm of the switch in the starting process is solved, the blocking of a network channel is avoided, and the normal forwarding of the data message is ensured.
Example two
Fig. 2 is a flowchart of a startup control method of a switch according to a second embodiment of the present invention. The present embodiment is embodied on the basis of the foregoing embodiment, where after determining, by the host system, a switch role of the switch in the switch ring network, the method may further include: if the main system determines that the switch roles of the switch are changed before and after power failure, according to a fast redundancy ring protocol, after the state of each port is set again, port configuration information corresponding to each port in the switch is obtained; and sending the port configuration information to the quick start forwarding system through the main system so as to instruct the quick start forwarding system to update and store the port configuration information locally.
As shown in fig. 2, the method for controlling the startup of the switch provided in this embodiment is executed by the switch in the switch ring network, where the switch includes: the quick-start forwarding system and the main system, and the quick redundancy ring function of the switch opened in the switch ring network specifically comprises:
and S210, after the switch is powered down and powered up again, executing the starting process of the quick start forwarding system and the main system at the same time, wherein the starting speed of the quick start forwarding system is faster than that of the main system.
S220, after the start-up is completed through the quick start forwarding system, each switching port in the switch is configured according to the locally stored port configuration information, and forwarding control is performed on the received message after the configuration is completed.
The port configuration information is adapted to the port states of all ports set in the switch ring network before the switch is powered down.
S230, after the starting is completed through the main system, taking over the control right of the quick start forwarding system to the switch, and forwarding and controlling the received message.
S240, reading the root port in the switch ring network through the main system according to the quick redundancy ring function configured by the main system.
As described above, if the fast redundancy ring function is turned on in the switch, it is necessary to simultaneously set the root port included in the switch ring network to which the switch is adapted, for example, the unique identification of the root port, inside the switch.
S250, determining the role of the switch in the switch ring network by the main system according to whether each port in the switch comprises the root port.
In this embodiment, when the switch determines that the root port is included in the own device, the switch role of the switch itself is described as the master switch, and when the switch determines that the root port is not included in the own device, the switch role of the switch itself is described as the slave switch.
And S260, if the master system determines that the switch role is the master switch, executing a control protocol matched with the master switch in the fast redundancy ring protocol.
If the switch is determined to be the master switch after being started and the fast redundancy ring function is started in advance, the fast redundancy detection message is sent through the master port regularly, whether the slave port receives the fast redundancy detection message is detected, and further whether the slave port is set to be in a forwarding state or in a blocking state can be determined according to whether the slave port can receive the fast redundancy detection message.
And S270, if the master system determines that the switch role is the slave switch, executing a control protocol matched with the slave switch in the fast redundancy ring protocol.
If the switch is determined to be the main switch after being started and the fast redundancy ring function is started in advance, the received fast redundancy detection message is forwarded through each port of the switch.
S280, if the main system determines that the switch roles of the switch are changed before and after power failure, the main system acquires port configuration information corresponding to each port in the switch after carrying out state setting on each port again according to a fast redundancy ring protocol.
Further, if the switch finds itself to change its role before and after power failure, it needs to reset the state of each port.
Typically, if the switch role of the switch is changed from master to slave, each port needs to be set to a forwarding state; if the switch role of the switch is changed from slave to master, then the master port of itself needs to be set to forwarding state and the slave port needs to be set to blocking state. At this time, the port configuration information stored in the quick start forwarding system is no longer accurate, and when the switch is restarted, the port configuration according to the port configuration information stored in the quick start forwarding system cannot effectively avoid broadcast storm. Furthermore, the port configuration information in the quick start forwarding system needs to be updated and stored.
And S290, sending the port configuration information to the quick start forwarding system through the main system so as to instruct the quick start forwarding system to update and store the port configuration information locally.
Optionally, sending, by the host system, the port configuration information to the fast forwarding system may include: and transmitting port configuration information to the quick start forwarding system by the main system through a serial peripheral interface channel between the main system and the quick start forwarding system.
In the embodiment of the invention, data interaction can be performed between the quick start forwarding system and the main system through a serial peripheral interface (Serial Peripheral Interface, SPI), namely, the main system sends port configuration information to the quick start forwarding system through the SPI for updating and storing.
The present embodiment is not explained in detail herein, and reference is made to the foregoing embodiments.
According to the technical scheme, if the main system determines that the role of the switch is changed before and after power failure, the main system acquires port configuration information corresponding to each port in the switch after carrying out state setting on each port again according to the fast redundancy ring protocol; the port configuration information is sent to the quick start forwarding system through the main system, so that the quick start forwarding system is instructed to update and store the port configuration information locally, the quick start forwarding system is used for updating port configuration information of each switch in the stored ring network when the switch role is changed in the switch ring network, timeliness of the port configuration information stored by the quick start forwarding system is guaranteed, and the problem of broadcast storm of the switch in the next starting process is solved.
On the basis of the above embodiments, the method may further include:
acquiring port configuration information corresponding to each port in the switch by the main system in response to a configuration storage instruction input by a user;
the port configuration information is sent to a quick start forwarding system through the main system, so that the quick start forwarding system is instructed to update and store the port configuration information locally;
the configuration storage instruction is triggered to be generated after the topological structure of the switch ring network is changed.
The configuration storage instruction is triggered to be generated after the topological structure of the switch ring network is changed. The configuration storage instruction refers to an instruction issued by a user to save the configuration information of the switch port.
When the topology structure of the switch ring network changes, a user can trigger to generate a configuration storage instruction, and after receiving the configuration storage instruction, the main system acquires port configuration information corresponding to each port in the switch so as to update and store the port configuration information.
The host system sends the port configuration information to the singlechip, and the singlechip updates and stores the port configuration information in a FLASH memory of the host system, so that timeliness of the port configuration information stored in the quick-start forwarding system is ensured, and each exchange port in the switch can be configured according to the updated port configuration information stored in the singlechip when the switch is started next time.
