Next, examples of the present application will be described in detail.
Fig. 1 is a flowchart illustrating a method for monitoring a link health status according to an exemplary embodiment of the present application. As shown in fig. 1, the method is applied to a load balancing device, where the load balancing device is configured to implement load sharing of traffic for multiple physical links, and may include the following steps:
step 102: and acquiring messages flowing through each physical link.
The load balancing device receives the flow and distributes the flow to different physical links through a certain scheduling algorithm, thereby realizing the load sharing of the flow. The load balancing device needs to monitor the health status of each physical link to ensure that traffic is scheduled to the physical link with a healthy status, so that an available link with a higher priority can be selected according to a corresponding scheduling algorithm in the traffic scheduling process to realize traffic forwarding.
In an embodiment, the load balancing device obtains messages flowing through each physical link, counts the messages of each physical link according to the protocol type and/or the destination address of the obtained messages, and classifies the messages flowing through each physical link and having the same protocol type and/or the same destination address. By counting the acquired messages, the protocol type and/or the destination address distribution condition of the messages on the link can be acquired more intuitively, and unnecessary repeated monitoring on the link is reduced when abnormal messages of the same protocol type and/or the same destination address are acquired subsequently.
Step 104: when determining that an abnormal message exists on any physical link, sending a monitoring message through the any physical link to monitor the health state of the any physical link; the abnormal message is a predefined message used for indicating that the physical link has abnormal possibility.
In the link health status monitoring method of the related art, the monitoring target, the monitoring protocol, the monitoring message content and the sending time interval of the monitoring message are all configured in advance manually. The load balancing equipment sends a monitoring message, and if a reply message aiming at the monitoring message is received within a preset time length, the physical link is determined to be in a healthy state; and if the reply message aiming at the monitoring message is not received within the preset time length, determining that the physical link is in a fault state.
In an embodiment, an exception packet is predefined, where the exception packet is a packet that may flow through a physical link when the physical link has an exception. For example, when the TCP protocol connection fails, the TCP reset packet flows through the physical link, so the TCP reset packet can be predefined as an abnormal packet; when the destination address of the UDP packet sent by the load balancing device is unreachable, the ICMP unreachable packet may flow through the physical link, so the ICMP unreachable packet may be predefined as an abnormal packet. In fact, all messages that may flow through the physical link when the physical link is in a failure state may be applied to this, and this is not limited in this application. By analyzing the message flowing through the link and determining whether to perform health monitoring on the physical link according to whether an abnormal message exists on the physical link, the load balancing equipment can timely perform health state monitoring on the physical link when detecting that the abnormal message exists on the physical link and accordingly judging that the physical link is possibly abnormal, real-time monitoring on the health state of the physical link is achieved to a certain extent, and the physical link is not subjected to health monitoring when the abnormal message is not monitored, namely the physical link is not abnormal, so that unnecessary resource waste can be reduced.
In an embodiment, the load balancing device counts the common characteristics of the abnormal messages; and generating a monitoring message matched with the common characteristic so as to monitor the health state of any physical link. Wherein the common features include: the protocol type and/or the destination address of the message. The generating of the monitoring message matched with the common characteristic includes: when the common characteristic of the abnormal message is a protocol type, generating a monitoring message which has the same protocol type as the abnormal message; and when the common characteristic of the abnormal message is a destination address, generating a monitoring message with the same destination address as the abnormal message. For example, when the abnormal message flowing through the physical link is counted and obtained as a TCP reset message, a monitoring message is generated as a TCP connection request message; and when the abnormal message flowing through the physical link is counted as the ICMP destination unreachable message, generating a playback request message of which the monitoring message is the same as the destination address of the ICMP destination unreachable message. The method is different from the monitoring messages which are manually configured in advance in the prior art, and the monitoring messages which are matched with the common characteristics of the abnormal messages are automatically generated by counting the common characteristics of the abnormal messages, so that the monitoring messages sent by the load balancing equipment are more flexible and have higher pertinence, all protocol types and destination addresses of the flow passing through the link can be covered, and the health states of the physical link aiming at all protocol types and destination addresses can be reflected.
In one embodiment, load data of any one of the physical links is acquired; and determining the sending frequency and the sending quantity of the monitoring messages according to the load data, so that the load data when any physical link sends the monitoring messages does not exceed the preset load data. For example, if the load data of the physical link is less than 30%, the sending number and sending frequency of the monitoring messages can be properly increased; if the load data of the physical link is greater than 80%, the sending number and the sending frequency of the monitoring messages can be properly reduced. By counting the load condition of the physical link, the sending frequency and the sending quantity of the monitoring messages can be adjusted and controlled in time, the load pressure of the physical link is prevented from being overlarge, the monitoring efficiency of the physical link is improved, and the influence on the normal flow forwarding work of the physical link can be reduced.
In an embodiment, a physical link is provided with a fixed bandwidth, the traffic of any physical link is counted, and the load data of any physical link is determined according to the traffic and the bandwidth. For example, if the physical link is configured with a fixed bandwidth of 80Mbps, the flow rate flowing through the link per second may be up to 10MByte/s, and the current flow rate of the physical link is 2MByte/s, which can be calculated to obtain that the load data of the physical link is 20%. In fact, all methods for obtaining load data can be applied to this, and the present application is not limited to this. Load data of the physical link is calculated by counting the flow of the physical link, so that the sending frequency and the sending quantity of monitoring messages can be adjusted conveniently and timely, and more sufficient data support can be provided for subsequent flow scheduling.
According to the technical scheme, the physical link health state monitoring method and the physical link health state monitoring system have the advantages that the messages flowing through the physical link are analyzed, the physical link health state is monitored when the abnormal messages are determined, the physical link health state monitoring can have higher timeliness and reduce resource waste, the specific content of the monitored messages can be flexibly changed according to the abnormal messages, the physical link health state can be monitored in a more targeted mode, and the monitoring accuracy is improved.
Fig. 2 is a schematic diagram of a network architecture of a link health status monitoring system to which an embodiment of the present invention is applied. As shown in fig. 2, the link health monitoring system may include a client 21, a load balancing device 22, and a server cluster 23. The server cluster 23 includes a plurality of servers, such as the server 23a, the server 23b, and the server 23c shown in fig. 2, but the number of servers included in the server cluster 23 is not limited in the present application. The load balancing device 22 performs health monitoring on each physical link between itself and each server in the server cluster 23 to determine whether each physical link is in a healthy state. The client 21 sends the traffic to the load balancing device 22, and the load balancing device 23 selects a healthy link to send the traffic to each server in the server cluster 23, so as to implement load sharing of the traffic. It should be noted that the network architecture illustrated in fig. 2 is only an illustration of the simplest network architecture for implementing the present application, and the practical application may be expanded according to the actual situation.
In the technical solution of the present application, the health status of each physical link between the load balancing device 22 and each server in the server cluster 23 can be obtained in time by improving the health status monitoring process of each physical link, which is described in detail below with reference to fig. 3. Fig. 3 is a detailed flowchart illustrating a method for monitoring a link health status according to an exemplary embodiment of the present application. As shown in fig. 3, the process of the load balancing device 22 performing health status monitoring on the physical link between the load balancing device and the server cluster 23 includes the following steps:
In this embodiment, the traffic received by the load balancing device 22 and sent by the client 21 is forwarded to each server in the server cluster 23 through a plurality of physical links, so as to implement load sharing of the traffic. There are physical links between the load balancing device 22 and each server in the server cluster 23, and traffic can be sent to each server through each physical link. And acquiring messages flowing through each physical link.
In this embodiment, the load balancing device 22 defines an abnormal packet for indicating that there is an abnormal possibility in the physical link in advance, and can determine whether there is an abnormal packet in each physical link by analyzing the acquired packet flowing through each physical link.
For example, it is analyzed that abnormal messages, such as a TCP re-request message identified as [ TCP dup ack ], a TCP Fast Retransmission message identified as [ TCP Fast Retransmission ], and a TCP timeout Retransmission message identified as [ TCP Retransmission ], exist on the physical link between the load balancing device 22 and the server 23a, and the protocol types of the abnormal messages are TCP protocols.
In this embodiment, the load balancing device 22 generates a monitoring packet matching the common characteristic of the abnormal packet according to the common characteristic of the abnormal packet obtained by statistics.
According to the above example, the protocol types of the abnormal messages on the physical link between the load balancing device 22 and the server 23a are both TCP protocols, and the load balancing device 22 generates a TCP connection request message whose protocol type is also TCP protocol and whose flag bit is [ SYN ] sequence number Seq is 0 as a monitoring message.
And step 304, counting the flow of any physical link, and determining the load data of any physical link according to the flow and the bandwidth.
In this embodiment, the physical link has a fixed bandwidth, for example, the fixed bandwidth configured for the physical link is 80Mbps, the flow rate flowing through the link per second may be up to 10MByte/s, the current flow rate of the physical link is obtained by statistics as 2MByte/s, and it can be calculated that the load data of the physical link between the load balancing device 22 and the server 23a is 20%.
In step 305, the load balancing device 22 determines the sending frequency and the sending number of the monitoring packets according to the load data, so that the load data when the monitoring packets are sent by any physical link does not exceed the preset load data.
In this embodiment, a standard sending frequency is configured in advance to send the monitoring messages every 10s, the load data of the physical link between the load balancing device 22 and the server 23a is 20%, the load is small, the sending number and the sending frequency of the monitoring messages can be appropriately increased, and the load balancing device 22 automatically sets the sending frequency to send the monitoring messages every 8 s.
In this embodiment, the load balancing apparatus 22 sends a TCP connection request packet with a flag bit of [ SYN ] sequence number Seq equal to 0 every 8s to flow through the physical link between itself and the server 23 a.
In this embodiment, after receiving the monitoring message, the server 23a returns, as a reply message, an acknowledgement message with a flag bit of [ SYN, ACK ] and a sequence number of Seq ═ 0 and an acknowledgement number of ACK ═ x +1 to the load balancing device 22, where the acknowledgement message may indicate that the server 23a confirms that the sequence number of the TCP connection request message sent by the load balancing device 22 is valid, and the server 23a can normally receive the data sent by the load balancing device 22 and agree to create a new connection. If the load balancing device 22 receives a reply message for the TCP connection request within a preset time, it determines that the physical link is in a healthy state; if the load balancing device 22 does not receive the reply message for the TCP connection request within the preset time, it determines that the physical link is in a failure state.
