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

Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1a is a flowchart of a method for controlling a start of a switch according to an embodiment of the present invention, where the method is applicable to solving a broadcast storm, avoiding a network channel from being blocked, and ensuring normal forwarding of a data packet.
As shown in fig. 1a, the start control method for an exchange provided in this embodiment is executed by an exchange in an exchange ring network, where the exchange includes: quick-start forwarding system and main system, just the switch is in the quick redundant ring function of opening in the switch looped netowrk specifically includes:
and S110, after the switch is powered off and powered on again, simultaneously executing the starting process of the quick-start forwarding system and the main system, wherein the starting speed of the quick-start forwarding system is higher than that of the main system.
In this embodiment, each switch included in the switch ring network starts a fast-start function in advance, that is, after 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, and can quickly execute a simple packet forwarding processing procedure.
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 carrying out forwarding processing on received messages on a comparison basis by a user.
The main system is used for processing all function items of the switch, such as forwarding control of received messages and the like, and the starting speed is low.
It can be understood that, after the switch in the switch ring network is powered down and powered up again, the fast-boot forwarding system in the switch and the main system are also powered up synchronously, wherein each switch in the switch ring network starts the fast redundant ring function.
As an optional implementation, the fast-boot forwarding system is a single chip, and the main system is a central processing unit of the switch.
In this embodiment of the present invention, the fast boot forwarding system may be a single chip with a memory, and the main system may be a Central Processing Unit (CPU) inside a switch with a switch chip, where the memory may be a non-volatile memory such as FLASH and ROM, and the switch chip may be a chip KD5660, and this is not specifically limited in this embodiment of the present invention. The quick-start forwarding system and the main system can be connected through the bus and perform data interaction.
And S120, after the quick-start forwarding system is started, configuring each switching port in the switch according to the locally stored port configuration information, and after the configuration is finished, performing forwarding control on the received message.
The port configuration information is adapted to the port state of each port 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 and the like, after the configuration of a fast redundancy RING protocol (DT-RING) used in the switch RING network takes effect.
The method includes that port configuration information of each switching port in a switch is stored in a memory of a quick-start forwarding system 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 a FLASH memory is read, then a relevant register in a switching chip of the switch is configured according to the port configuration information, states of each switching port are set, and after the port configuration information is configured, the quick-start forwarding system can perform forwarding control on a received message, for example, two-layer forwarding or three-layer forwarding control on the received message.
It can be understood that in the switch ring network formed by the switches, the loop protocol can be selected as the fast redundancy loop protocol, and each switch starts the fast redundancy function in advance.
The basic principle of the fast redundancy ring protocol is as follows: appointing a main switch and a slave switch in a switch ring network, and appointing a main port and a slave port of the main switch, wherein the main port is in a forwarding (forward) state, the main port of the main switch sends a fast redundancy detection message, and the slave port detects whether the fast redundancy ring detection message is received; if yes, it indicates that there is a logic loop in the current switch system, and the slave port of the master switch needs to be set to a blocking (block) state to disconnect the loop; if not, the slave port of the main switch is set to be in a forwarding state, so that the forwarding path is increased to the maximum extent. Therefore, the rapid 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 fast-boot forwarding system is booted, configuring each switching port in the switch according to the locally stored port configuration information, which may include: after the quick-start forwarding system is started, according to locally stored port configuration information, a main port in a main switch is set to be in a forwarding state, and a slave port in the main switch is set to be in a blocking state.
The switch ring network comprises a plurality of switches, the switches comprise a main switch and at least one slave switch, and the main switch comprises a main port and a slave port. When the fast redundancy ring protocol is used in the ring network of the switch, the main port of the main switch is set to be in a forwarding state, and the auxiliary port is set to be in a blocking state, namely, the port configuration information of the fast start forwarding system corresponding to the main switch, which is locally stored, is set.
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 auxiliary port in the main switch is set to be in a blocking state, so that a logic loop cannot appear in the whole switch ring network.
Optionally, the switch is a slave switch in a switch ring network; after the fast-boot forwarding system is booted, configuring each switching port in the switch according to the locally stored port configuration information, which 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 switch ring network, each port of the slave switch is set to be in a forwarding state, namely, the port configuration information of the fast start forwarding system corresponding to the slave switch, which is locally stored, is used, so that when the fast start forwarding system configures the slave switch according to the port configuration information, each port in the slave switch can be set to be in the forwarding state.
By way of example and not limitation, a scenario of 1 master switch and 4 slave switches is shown in FIG. 1 b. Wherein, each switch interconnects in turn and constitutes a switch looped network together. Alternatively, the number of slave switches is not limited to 4, and may be 1 or 5, and the like. 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, and all the ports of the 4 slave switches are set to be in the forward state.
And S130, after the main system is started, taking over the control right of the quick-start forwarding system to the switch, and performing forwarding control on the received message.
After the quick-start forwarding system completes configuration of each switching port in the switch, the switch is not subjected to other configuration, the control right of the switch is released, after a main system of the switch is powered on and started, the main system takes over the control right and performs forwarding control on a received message, and at the moment, the starting control of the switch is completed.
As an optional implementation manner, after the main system takes over the control right of the fast-boot forwarding system to the switch after completing the boot, and performs forwarding control on the received packet, the method may further include:
reading a root port in the switch ring network through the main system according to a quick redundant ring function configured by the main system; determining, by the host system, a switch role of the switch in the switch ring network according to whether each port in the switch includes the root port; if the main system determines that the switch role is the main switch, executing a control protocol matched with the main switch in a fast redundancy ring protocol; and 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.
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 kinen 6000 switch configured with the fast redundancy ring protocol, a port 4 is specified as the root port. Therefore, after the main system takes over the control right of the switch, the main system can read the root port in the switch ring network according to the fast redundancy ring protocol configured by the local machine, if the root port belongs to the port in the local machine, the switch is determined as the main switch, and the control protocol matched with the main switch in the fast redundancy ring protocol is executed, namely, the fast redundancy detection message is sent through the main port periodically, and whether the fast redundancy detection message is received by the slave port is detected; if the root port does not belong to the port in the local switch, the switch is determined to be the slave switch, and a control protocol matched with the slave switch in the fast redundancy ring protocol is executed, namely the fast redundancy detection message is forwarded.
In the technical scheme provided by the embodiment of the invention, when the switch in the switch ring network is powered off and powered on again, the starting process of the quick-start forwarding system and the main system is executed at the same time, after the quick-start forwarding system is started, each switching port in the switch is configured according to the locally stored port configuration information, the received message is forwarded and controlled after the configuration is completed, the main system takes over the control right of the quick-start forwarding system to the switch after the starting is completed, the received message is forwarded and controlled, 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 broadcast storm problem of the switch in the starting process is solved, the network channel is prevented from being blocked, and the normal forwarding of the data message is ensured.
Example two
Fig. 2 is a flowchart of a method for controlling startup of a switch according to a second embodiment of the present invention. This embodiment is embodied on the basis of the foregoing embodiment, wherein after determining, by the host system, the switch role of the switch in the switch ring network, the method may further include: if the main system determines that the role of the switch is changed before and after the switch is powered down, the main system resets the state of each port according to a fast redundancy ring protocol and then acquires port configuration information corresponding to each port in the switch; 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 locally update and store the port configuration information.
As shown in fig. 2, the start control method for the switch provided in this embodiment is executed by the switch in the ring network of switches, and the switch includes: quick-start forwarding system and main system, just the switch is in the quick redundant ring function of opening in the switch looped netowrk specifically includes:
s210, after the switch is powered off and powered on again, starting the quick-start forwarding system and the main system at the same time, wherein the starting speed of the quick-start forwarding system is higher than that of the main system.
S220, after the quick-start forwarding system is started, all the switching ports in the switch are configured according to the locally stored port configuration information, and after the configuration is completed, the forwarding control is carried out on the received message.
The port configuration information is adapted to the port state of each port set in the switch ring network before the switch is powered down.
And S230, after the main system is started, taking over the control right of the quick-start forwarding system to the switch, and performing forwarding control on the received message.
S240, reading a 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, the root port included in the switch ring network to which the switch is adapted, for example, the unique identification of the root port, needs to be set inside the switch at the same time.
S250, determining the switch 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 local computer, it indicates that the switch role of the switch itself is the master switch, and when the switch determines that the root port is not included in the local computer, it indicates that the switch role of the switch itself is the slave switch.
S260, if the main system determines that the switch role is the main switch, executing a control protocol matched with the main switch in a fast redundancy ring protocol.
If the switch is started, the local switch is determined to be a main switch, and the fast redundancy ring function is started in advance, the fast redundancy detection message is sent through the main port regularly, whether the fast redundancy detection message is received by the slave port is detected, and then the slave port is determined to be set to be in a forwarding state or a blocking state according to whether the fast redundancy detection message can be received by the slave port.
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 started, the local computer is determined to be the main switch, and the fast redundancy ring function is started in advance, the received fast redundancy detection message is forwarded through each port of the local computer.
S280, if the main system determines that the role of the switch is changed before and after the switch is powered down, the main system resets the state of each port according to a fast redundancy ring protocol and then acquires port configuration information corresponding to each port in the switch.
Further, if the switch finds that the role of the switch changes before and after the power failure, the state of each port needs to be set again.
Typically, if the switch role of the switch is changed from the master switch to the slave switch, each port needs to be set to a forwarding state; if the switch role of the switch is changed from the slave switch to the master switch, the master port of the switch needs to be set to a forwarding state, and the slave port needs to be set to a blocking state. At this time, the port configuration information stored in the fast-start forwarding system is no longer accurate, and when the switch is restarted, the broadcast storm cannot be effectively avoided according to the port configuration information stored in the fast-start forwarding system. Furthermore, it is necessary to update and store the port configuration information in the fast-boot forwarding system.
And S290, sending the port configuration information to the quick-start forwarding system through the main system to instruct the quick-start forwarding system to locally update and store the port configuration information.
Optionally, sending the port configuration information to the fast-boot forwarding system through the host system may include: and sending the port configuration information to the quick-start forwarding system by the main system by adopting a serial peripheral interface channel between the main system and the quick-start forwarding system.
In the embodiment of the present invention, data interaction may be performed between the fast-boot forwarding system and the host system through a Serial Peripheral Interface (SPI) channel, that is, the host system sends the port configuration information to the fast-boot forwarding system through the SPI channel to perform update and storage.
For those parts of this embodiment that are not explained in detail, reference is made to the aforementioned embodiments, which are not repeated herein.
According to the technical scheme, if the main system determines that the role of the switch is changed before and after the switch is powered down, the main system resets the state of each port according to the fast redundancy ring protocol and then acquires port configuration information corresponding to each port in the switch; the port configuration information is sent to the quick-start forwarding system through the main system so as to indicate the quick-start forwarding system to locally update and store the port configuration information, when the switch in the switch ring network changes the role of the switch, the quick-start forwarding system updates the stored port configuration information of each switch in the ring network, the timeliness of the port configuration information stored by the quick-start forwarding system is ensured, and the problem of broadcast storm of the switch in the next starting process is solved.
On the basis of the foregoing embodiments, the method may further include:
responding to a configuration storage instruction input by a user through the main system, and acquiring port configuration information corresponding to each port in the switch;
sending the port configuration information to a quick-start forwarding system through the main system so as to instruct the quick-start forwarding system to locally update and store the port configuration information;
and triggering and generating the configuration storage instruction after the topological structure of the switch ring network changes.
The configuration storage instruction is triggered and generated after the topological structure of the switch ring network changes. The configuration storage instruction refers to an instruction issued by a user for storing the switch port configuration information.
When the topology structure of the switch ring network changes, a user can trigger and 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.
Illustratively, the main system sends the port configuration information to the single chip microcomputer, and the single chip microcomputer updates and stores the port configuration information into a FLASH memory of the single chip microcomputer, so that timeliness of the port configuration information stored in the quick-start forwarding system is guaranteed, and therefore when the switch is started next time, each switching port in the switch can be configured according to the updated port configuration information stored in the single chip microcomputer.
