Detailed Description
The terminology used in the embodiments of the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein is meant to encompass any and all possible combinations of one or more of the associated listed items.
It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information in the embodiments of the present disclosure, such information should not be limited by these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. Depending on the context, moreover, the word "if" as used may be interpreted as "at … …" or "when … …" or "in response to a determination".
As shown in fig. 4, a server service networking is mainly configured as follows: the server is connected with the ICM through a Mezz network card, the ICM is connected with a Switch, and the Switch is communicated with an external service network; two ports P1 and P2 on the Mezz network card are respectively connected with the ICM-1 and the ICM-2, and the server performs bond0 mode binding (polling strategy) on the two ports P1 and P2; the ICM-1 and the ICM-2 are made into IRF (stack) to be virtualized into a device, and one port of each of the ICM-1 and the ICM-2 is connected to the Switch device.
The service networking realizes that the Mezz network card is connected with the opposite terminal equipment Switch through two stacked links (respectively connected through ICM-1 and ICM-2).
The networking has the advantages that the load balance of the service can be realized, but the disadvantages are as follows: that is, only after the physical state of the port is changed to down, the flow is transferred to the link in the active state, and when the message cannot be forwarded normally due to link oscillation or other faults, correct judgment cannot be made, and service migration cannot be performed.
In view of the above, the present disclosure provides a method and an apparatus for managing a link of a blade box, an electronic device, and a machine-readable storage medium, so as to solve the problem that the link oscillation cannot be handled in time.
The specific technical scheme is as follows.
In one embodiment, the present disclosure provides a method for managing a blade box link, which is applied to a network device, and the method includes: attempting to receive a detection message sent by opposite terminal equipment through a first link; if the detection message sent by the opposite terminal equipment is not received according to the preset rule, the first link is judged to be in a fault state; sending a fault information message to opposite terminal equipment through a second link, and switching the flow borne by the first link to the second link; and the opposite terminal equipment is used for switching the flow borne by the first link to the second link according to the received fault information message.
Specifically, as shown in fig. 1, the method comprises the following steps:
step S11, receiving the detection message sent by the opposite terminal equipment through the first link;
step S12, if the detection message sent by the opposite terminal equipment is not received according to the preset rule, the first link is judged to be in the fault state;
step S13, sending a failure information message to the peer device through the second link, and switching the traffic carried in the first link to the second link.
And the opposite terminal equipment is used for switching the flow borne by the first link to the second link according to the received fault information message.
The network card of the knife box and the opposite terminal equipment switch respectively send detection messages through each connected link, when a certain link fails to receive the detection messages sent by the opposite terminal equipment according to a preset rule, the local equipment judges that the link fails, flow borne by the link is switched to a normally communicated link, and fault information is sent to the opposite terminal equipment through the normally communicated link so that the opposite terminal equipment can switch the flow borne by the failed link to the normally communicated link, and therefore link oscillation is timely processed, and the phenomenon that the messages cannot be normally forwarded is avoided.
In this embodiment, the network device may refer to a mesh board Mess of the blade box, or may be a Switch connected to the mesh board of the blade box through at least two links, for example, as shown in fig. 4, the blade box server is connected to two ICM Switch mesh boards through a Mezz network card, the Switch is connected to the ICM, and the Switch communicates with an external service network. Correspondingly, the opposite-end device refers to a Switch, and may also be a network board Mess of a blade box connected with the Switch through at least two links.
In an embodiment, the attempting to receive, through the first link, a detection packet sent by the peer device includes: attempting to receive a detection message periodically sent by opposite terminal equipment through a first link; if the detection message sent by the opposite terminal device is not received according to the preset rule, it is determined that the first link is in a failure state, including: and if the detection messages periodically sent by the opposite terminal equipment cannot be received in the continuous preset number of periods, judging that the first link is in a fault state.
The link detection switching message is a bidirectional message, that is, the network card and the switch of the knife box server can both send and receive simultaneously, and in addition, after the link failure is detected on any end device port, the link detection switching message can be uploaded to the CPU of the device where the port is located for processing.
Based on the realization mode, the link fault detection and service switching mechanism realizes the following processes:
since the link detection switching message is a bidirectional detection message between the network board of the blade box server and the Switch, DEV-1 and DEV-2 represent the network card of the blade box server and the Switch for convenience of describing the embodiment provided by the present disclosure, wherein DEV-1 or DEV-2 device may represent either the network card of the blade box server pass or the Switch. Namely: if the DEV-1 is a tool box server Mess network card, the DEV-2 is a Switch at the moment; if the DEV-1 is the Switch, the DEV-2 is a tool box server Mess network card at the moment;
the device DEV-1 is connected to the device DEV-2 via a first link and a second link, wherein the ports at both ends of the first link are respectively the port P1 located at the device DEV-1 and the port T1 located at the device DEV-2, and the ports at both ends of the second link are respectively the port P2 located at the device DEV-1 and the port T2 located at the device DEV-2.
After the port P1 of the device DEV-1 is in the physical state UP, the DEV-1 side starts to send a link detection switch message from the port P1 to the port T1 of the peer device DEV-2 for link state detection, where the sending period of the message may be 10ms (10 ms) or other values that meet the application scenario, and as long as the port P1 is in a normal state (active), the value of the Status Code carried in the link detection switch message sent from the port is always kept to 0 (indicating that the link state is normal).
After receiving the link detection switching message from the T1 port, the DEV-2 side updates and records the related information (such as port name, mac address, etc.) of the peer P1 port, immediately triggers the detection timer of the T1 port, and starts to record the message detection time.
At the T1 port, starting from the trigger of the detection timer, within 3 (or other cycle numbers conforming to the application scenario) link detection switching message detection message periods (i.e. 30ms), if the T1 port can receive the link detection switching message sent by the P1 port, the T1 port state is considered normal, and the first link state is normal.
If the T1 port cannot receive the link detection switching message sent from the P1 port within 3 link detection switching message detection message periods (and 30ms), the T1 port state is considered to be abnormal, the first link fails, and at this time, the link detection switching message with the Status Code set to 1 (indicating the link state failure) is sent to the CPU of DEV-2 for processing;
at this time, DEV-2 will set the state of the T1 port to recovery (representing that the T1 port fails and the link where the port is located is unavailable), and switch the traffic of the T1 port to the T2 port.
DEV-2 sends a link detection switching message carrying T1 port information (Status Code is 1, which indicates T1 port failure and link where the port is located is unavailable) to DEV-1 through a T2 port, and after receiving the message, DEV-1 sets the state of a P1 port as recovery (which indicates P1 port failure and link where the port is located is unavailable), and switches the flow of the P1 port to a P2 port.
In one embodiment, after determining that the first link is in the failure state, the method includes: attempting to receive a detection message sent by opposite terminal equipment through a first link; if a detection message sent by the opposite terminal equipment is received according to a preset rule, judging that the first link recovers a normal state; sending a recovery information message to the opposite terminal equipment through the second link, and switching the flow originally borne on the first link on the second link back to the first link; and the opposite terminal equipment is also used for switching the flow originally borne on the first link on the second link back to the first link according to the received recovery information message.
If the first link is recovered to be normal after a period of time, the T1 port on the DEV-2 device can continuously receive a corresponding number of link detection switching packets (3) in 3 (or other values conforming to the application scenario) detection periods (10 ms per cycle, 30ms in total, or 10ms per cycle, or other values conforming to the application scenario), the state of the T1 port will be set to active (the port is available, and the link state of the port is normal), the T1 port is synchronized to the opposite DEV-1 device through the T2 port, and at this time, the devices at both ends will switch the traffic back to the P1-T1 link normally, and the forwarding function of the first link is recovered.
In one embodiment, a failure record of the first link is stored; and if the accumulated failure times of the first link within the continuous first preset time reach the threshold, stopping sending the recovery information message to the opposite terminal equipment through the second link within a second preset time after the threshold is reached.
In order to prevent link oscillation, if a port on a certain device reaches 2 times (or may be a value conforming to other application scenarios) within 10 minutes (or may be a value conforming to other application scenarios) and is marked as a recovery state, the port is considered to be in link oscillation, and the port state on the link is always set as recovery within 60 minutes (or may be a value conforming to other application scenarios) from this time, and traffic is always forwarded on a normal state link.
In an embodiment, the present disclosure also provides a device for managing a link of a blade box, as shown in fig. 2, applied to a network device, the device including: a receiving module 21, configured to attempt to receive a detection packet sent by an opposite end device through a first link; the determining module 22 is configured to determine that the first link is in a failure state if the detection packet sent by the peer device is not received according to the preset rule; the processing module 23 is configured to send a failure information packet to the peer device through the second link, and switch the traffic carried in the first link to the second link; and the opposite terminal equipment is used for switching the flow borne by the first link to the second link according to the received fault information message.
In an embodiment, the attempting to receive, through the first link, a detection packet sent by the peer device includes: attempting to receive a detection message periodically sent by opposite terminal equipment through a first link; if the detection message sent by the opposite terminal device is not received according to the preset rule, it is determined that the first link is in a failure state, including: and if the detection messages periodically sent by the opposite terminal equipment cannot be received in the continuous preset number of periods, judging that the first link is in a fault state.
In one embodiment, after the determining module determines that the first link is in the failure state, the method includes: the receiving module is also used for trying to receive a detection message sent by the opposite terminal equipment through the first link; the judging module is also used for judging that the first link is recovered to a normal state if receiving a detection message sent by the opposite terminal equipment according to a preset rule; the processing module is further configured to send a recovery information packet to the peer device through the second link, and switch the traffic originally carried on the second link in the first link back to the first link; and the opposite terminal equipment is also used for switching the flow originally borne on the first link on the second link back to the first link according to the received recovery information message.
