Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
Technical features mentioned in the different embodiments of the present disclosure described below may be combined with each other as long as they do not conflict with each other.
It should be noted that, in all embodiments provided in the present disclosure, the first VSR device refers to a first virtual service router device, and the second VSR device refers to a second virtual service router device, where the first and second VSR devices are used for illustration only and do not represent importance, and in practical applications, the first VSR device and the second VSR device may be interchanged.
Fig. 1 shows an architecture diagram of a prior art IRF system. As shown in fig. 1, a plurality of VSR devices (a first VSR device 110 and a second VSR device 120 are exemplarily illustrated in fig. 1) are created on a server in the IRF system in the prior art.
A VF1301 is obtained through simulation by a physical network card of a server in the IRF system, the stack channel 140 is established through the VF1301, and interaction of stack protocol messages is performed between the first VSR device 110 and the second VSR device 120 through the stack channel 140.
When the stacking channel 140 fails, the first VSR device 110 and the second VSR device 120 cannot sense, if traffic needs to be forwarded across devices, for example: when a certain service packet needs to be forwarded to the second VSR device 120 through the first VSR device 110, and then the second VSR device 120 forwards the service packet to the outside of the IRF system, the service packet transmission may be interrupted, and the controller in the IRF system may not sense the failure, which affects the normal transmission of the service traffic.
Fig. 2 shows an architecture diagram of an intelligent resilient architecture system, i.e., an IRF system, provided by an embodiment of the present disclosure. As shown in fig. 2, the IRF system in the embodiment of the present disclosure includes at least two VSR devices, where one VSR device is a main VSR device, and the remaining VSR devices are standby VSR devices (a first VSR device 210 and a second VSR device 220 are exemplarily illustrated in fig. 2).
A physical network card of a server in the IRF system establishes a first channel 241 through a first VF2301 and a second VF2302 obtained through simulation, establishes a second channel 242 through the second VF2302, and the first VSR device 210 and the second VSR device 220 transmit a service message and a detection message through the first channel 241 and the second channel 242, respectively.
In the embodiment of the present disclosure, the first channel 241 is a main channel, and the second channel 242 is a standby channel; alternatively, the first channel 241 is a standby channel, and the second channel 241 is a main channel. Specifically, taking the first channel 241 as a main channel and the second channel 242 as a standby channel as an example for explanation, the first VSR device 210 sends a detection message and a service message to the second VSR device 220 through the first channel 241, after receiving the detection message, the second VSR device 220, generates a confirmation message according to the detection message, and transmits the confirmation message to the first VSR apparatus 210 through the first channel 241, by determining whether the first VSR apparatus 210 receives the confirmation message within a preset time period, it is determined whether the first channel 241 is failed, if the first VSR apparatus 210 does not receive the acknowledgement message fed back by the second VSR apparatus 220 within the preset time period, the first channel 241 is considered to be faulty, and at this time, the first VSR device 210 may forward a corresponding service packet to the second VSR device 220 through the second channel 242, so as to ensure that the forwarding of the service traffic is performed normally; if the first VSR device 210 receives the confirmation message fed back by the second VSR device 220 within the preset time period, the first VSR device 210 assumes that the first channel 241 is in the normal state, and at this time, the first VSR device 210 may continue to forward the corresponding service message to the second VSR device 220 through the first channel 241, thereby implementing forwarding of the service traffic.
The interaction process between the first VSR apparatus 210 and the second VSR apparatus 220 is illustrated in fig. 2A or fig. 2B. It should be noted that, in practical applications, the first VSR apparatus 210 periodically sends the detection message to the second VSR apparatus 220 through the first channel 241 without interruption, the sending period may be reasonably set according to actual needs, for example, the sending period may be set to send the detection message every 5 seconds, and the preset time period may also be flexibly set according to actual needs, for example: in order to avoid the false determination of the failure, the preset time period may be 5 sending periods of the detection message, and if the confirmation message fed back by the second VSR device 220 cannot be received in any of the 5 sending periods of the detection message continuously, it is considered that the first channel 241 has the failure, which is not limited in this disclosure.
In summary, in the embodiment of the present disclosure, by setting the first channel and the second channel, when the first channel, i.e., the main channel, fails, the failure of the stacked link is detected in time, a transmission failure caused by an inability to sense when the communication channel fails in the existing IRF system is solved to a certain extent, and the forwarding of the service packet is completed through the second channel, i.e., the standby channel, thereby avoiding the interruption of the service traffic and ensuring the normal transmission of the service traffic.
Fig. 3 is a flowchart illustrating a message transmission method according to an embodiment of the present disclosure. The method can be applied to the first VSR device in the IRF system in the embodiment of fig. 2, and specifically includes the following steps:
step S301: a first VSR device (a first virtual service router device) sends a detection message and a service message to a second VSR device (a second virtual service router device) in the intelligent resilient framework system through a first channel, where the detection message is a message generated by the first VSR device and used to detect whether a first channel established by a virtual machine network card VF simulated by a physical network card PF in a server is faulty. In practical application, the detection message carries a first value (seg _ num value), the first VSR device randomly generates the first value, records the first value at the local end, and generates a detection message based on the first value. For example, the first VSR device generates a first value of 1, which is recorded as seg _ num ═ 1 at the end.
Step S302: and judging whether a confirmation message fed back by the second VSR equipment through the first channel is received within a preset time period, wherein the confirmation message is a message generated by the second VSR equipment according to the detection message. In practical application, the first VSR device may periodically and uninterruptedly send the detection message to the second VSR device through the first channel, and since the detection message may have a packet loss in a transmission process of the first channel or a transmission delay may be caused because a network card bandwidth is occupied, a channel fault misjudgment may be generated, and therefore, a fault misjudgment phenomenon caused by the packet loss or the transmission delay may be solved to a certain extent by reasonably setting a relationship between a preset time period and a detection message sending period.
Step S303: and when the confirmation message fed back by the second VSR equipment through the first channel is not received within a preset time period, determining that the first channel fails. The first VSR starts timing after sending the detection message through the first channel, detects whether the confirmation message is received or not when the distance exceeds a preset time period, and determines that the first channel has a fault if the confirmation message is not received. Specifically, the preset time period may be N times of a sending period set by the detection packet, where N is a natural number and N is greater than or equal to 1. For example, the transmission period set for the detection packet is Δ T, and the preset time period may be set to 5 Δ T, etc.
Step S304: and sending the service message to the second VSR equipment through the second channel. And after determining that the first channel has a fault, the first VSR equipment switches the transmission channel of the service message from the first channel to a second channel, and sends service data to the second VSR equipment through the second channel. Therefore, when the first channel fails, the service message is sent through the second channel, thereby avoiding the interruption of service flow and ensuring the normal transmission of the service flow.
In summary, in the embodiment of the present disclosure, by setting the first channel and the second channel, when the first channel, i.e., the main channel, fails, the failure of the stacked link is detected in time, a transmission failure caused by an inability to sense when the communication channel fails in the existing IRF system is solved to a certain extent, and the forwarding of the service packet is completed through the second channel, i.e., the standby channel, thereby avoiding the interruption of the service traffic and ensuring the normal transmission of the service traffic.
Specifically, in the embodiment of the present disclosure, as shown in fig. 2B, the message transmission method further includes:
step S305: and sending a detection message to the second VSR equipment through the first channel at intervals of a first time interval. In practical applications, after the first channel sends a failure, since the transmission rate and the transmission effect of the main channel, that is, the first channel, to the service packet are generally superior to those of the standby channel, that is, the second channel, the failure of the first channel needs to be monitored, and once the failure of the first channel is recovered, the first channel may be used to continue to transmit the service packet.
Step S306: and judging whether a confirmation message which is generated by the second VSR equipment based on the detection message and fed back through the first channel is received. Specifically, after the first VSR device sends the detection message through the first channel, if the failure of the first channel has recovered, the second VSR device may generate a confirmation message according to the received detection message and feed back the confirmation message to the first VSR device through the first channel, so that it may be determined whether the first channel has recovered from the failure by determining whether the confirmation message sent by the second VSR device is received.
Step S307: and when receiving a confirmation message fed back by the second VSR equipment through the first channel, determining that the first channel is recovered due to the fault. Specifically, if the first VSR device receives the confirmation message, it is considered that the first channel is recovered from the failure, and at this time, the transmission of the service message between the first VSR device and the second VSR device can be realized through the first channel, that is, the standby channel can be switched back to the main channel to transmit the service message, so that the flexible switching of the stacking link is realized. Of course, in practical applications, the service packet may also be continuously transmitted through the second channel, and the disclosure is not limited thereto.
In practical application, the first channel includes a first protocol channel and a first data channel, the first protocol channel is used for transmitting a detection message and a confirmation message, and the first data channel is used for transmitting a service message; the second channel also includes a second protocol channel and a second data channel, the second protocol channel is used for transmitting the detection packet and the confirmation packet, and the second data channel is used for transmitting the service packet. Therefore, the problem of false alarm fault of the protocol message caused by the fact that the service message occupies too full bandwidth in the transmission process is avoided to a certain extent by the mode that the protocol message such as the detection message, the confirmation message and the like and the service message are transmitted through different communication channels, the accuracy of channel detection is improved, and the two channels are used for transmitting the messages, so that the stack can be protected from splitting as far as possible.
Fig. 4 is a flowchart illustrating another message transmission method according to an embodiment of the present disclosure. The method may be applied to the second VSR device in the IRF system in the embodiment of fig. 2, and specifically includes the following steps:
step S401: and the second VSR equipment receives a detection message and a service message sent by the first VSR equipment in the intelligent elastic framework system through the first channel, wherein the detection message is used for detecting whether the first channel has a fault. Specifically, in practical application, if the second VSR device receives the detection message sent by the first VSR device through the first channel, it indicates that the current communication state of the first channel is in a normal state.
Step S402: and if the detection message is received, generating a confirmation message according to the detection message, and sending the confirmation message to the first VSR equipment through the first channel. Specifically, in practical application, a detection message received by the second VSR device carries a first numerical value (seg _ num value), the second VSR device analyzes the detection message to obtain the first numerical value contained in the detection message, generates a second numerical value based on the first numerical value according to a preset relationship, and generates a confirmation message based on the second numerical value. For example, if the second VSR device analyzes the detection message to obtain a first value seg _ num of 1, a second value seg _ num of 2 is generated, where the predetermined relationship is that the second value is the first value plus one. And sending the confirmation message carrying the second numerical value to the first VSR equipment through the first channel.
Step S403: and if the detection message is not received, receiving a service message sent by the first VSR equipment through the second channel, wherein the service message is sent through the second channel after the first channel is determined to be in fault when the first VSR equipment does not receive a confirmation message fed back by the second VSR equipment through the first channel within a preset time period. Specifically, in practical applications, after the first channel fails, the first channel cannot normally transmit the service packet, and therefore, the transmission channel of the service packet needs to be switched from the first channel, i.e., the main channel, to the second channel, i.e., the standby channel, so that the service packet is transmitted through the second channel, and normal transmission of the service traffic is ensured.
In summary, in the embodiment of the present disclosure, by setting the first channel and the second channel, when the first channel, i.e., the main channel, fails, the failure of the stacked link is detected in time, a transmission failure caused by an inability to sense when the communication channel fails in the existing IRF system is solved to a certain extent, and the forwarding of the service packet is completed through the second channel, i.e., the standby channel, thereby avoiding the interruption of the service traffic and ensuring the normal transmission of the service traffic.
Specifically, in the embodiment of the present disclosure, as shown in fig. 2B, the message transmission method further includes:
step S404: and receiving a detection message sent by the first VSR equipment to the second VSR equipment through the first channel at intervals of the first time through the first channel. In practical applications, after the first channel sends a failure, because the transmission rate and the transmission effect of the main channel, that is, the first channel, to the service packet are generally superior to those of the standby channel, that is, the second channel, the failure of the first channel needs to be monitored, and once the failure of the first channel is recovered, the first channel may be used to continue to transmit the service packet.
Step S405: and generating a confirmation message according to the detection message, and sending the confirmation message to the first VSR equipment through the first channel, so that the first VSR equipment determines the fault recovery of the first channel when receiving the confirmation message through the first channel. Specifically, if the first VSR device receives the confirmation message, it is considered that the first channel is recovered from the failure, and at this time, the transmission of the service message between the first VSR device and the second VSR device can be realized through the first channel, that is, the standby channel can be switched back to the main channel to transmit the service message, so that the flexible switching of the stacking link is realized. Of course, in practical applications, the service packet may also be continuously transmitted through the second channel, and the disclosure is not limited thereto.
In practical application, the first channel includes a first protocol channel and a first data channel, the first protocol channel is used for transmitting a detection message and a confirmation message, and the first data channel is used for transmitting a service message; the second channel also includes a second protocol channel and a second data channel, the second protocol channel is used for transmitting the detection packet and the confirmation packet, and the second data channel is used for transmitting the service packet. Therefore, the problem of false alarm fault of the protocol message caused by the fact that the service message occupies too full bandwidth in the transmission process is avoided to a certain extent by the mode that the protocol message such as the detection message, the confirmation message and the like and the service message are transmitted through different communication channels, the accuracy of channel detection is improved, and the two channels are used for transmitting the messages, so that the stack can be protected from splitting as far as possible.
