Technical Field

In addition, when the server detects the aggregation port physical link failure/sub-health, but does not detect a specific destination port link failure, even if the sending end switches the service to the network port in a normal state, due to the load algorithm of the switch chip, data still passes through the destination port failed link, which results in lower security and efficiency of data communication.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention are further described in detail with reference to the drawings and the embodiments, the described embodiments should not be construed as limiting the present invention, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.

To the extent that similar descriptions of "first/second" appear in this patent document, the description below will be added, where reference is made to the term "first \ second \ third" merely to distinguish between similar objects and not to imply a particular ordering with respect to the objects, it being understood that "first \ second \ third" may be interchanged either in a particular order or in a sequential order as permitted, to enable embodiments of the invention described herein to be practiced in other than the order illustrated or described herein.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing embodiments of the invention only and is not intended to be limiting of the invention.

Illustratively, in connection with fig. 1, in the related art, a server a and a server B perform data communication through a switch. The server a includes: port A1 and port A2. The server B includes: port B1 and port B2. The link 1 is formed by the internet access A1 and the internet access B1 from the server a to the server B. After the link between the switch and the network port B1 is failed, when the server a sends a service message to the server B, the server a switches the link to the link 2 corresponding to the network port A2, and due to the switch algorithm, the switch still sends the service message to the server B through the network port B1, so that the service message cannot be sent to the server B, and the data communication efficiency and the security are low.

Referring to fig. 2, a schematic flow chart of an alternative data processing method according to an embodiment of the present invention will be described with reference to the steps shown in fig. 2.

S101, in a current detection period, sending a certain number of current detection messages to each node to be detected based on the constructed virtual address information; the number of the certain quantity representations is larger than the number of the network ports corresponding to the nodes to be tested.

In the embodiment of the invention, the detection node sends a certain amount of current detection messages to each node to be detected based on the constructed virtual address information in the current detection period. The number of the certain quantity representations is larger than the number of the network ports corresponding to the nodes to be tested.

In the embodiment of the invention, the network system comprises a plurality of servers, equipment to be accessed and the like. Wherein, data communication is carried out among a plurality of servers through the switch. The probe node may be each server, device to be accessed, etc. The node to be tested may be a server other than the server corresponding to the probing node. That is, each server in the network system sends a certain number of current probe messages to each other server in each probe cycle. The plurality of portals of each server form a converged portal.

In the embodiment of the invention, the detection node determines the number of the network ports of each node to be detected in the local information table. And the server forms the current detection message of each node to be detected based on the constructed virtual address information. The number of the detection messages of each node to be detected is larger than the number of the corresponding network ports, so that the network ports of the nodes to be detected can be covered comprehensively by the detection messages.

In the embodiment of the invention, the detection node can send the corresponding current detection message to each node to be detected every 10 seconds. In other embodiments, the probe node may also send the current probe packet to each node to be tested every 1 minute. In the embodiment of the invention, the duration of the detection period is not limited.

In the embodiment of the present invention, when there are 10 servers in the network system, each server sends a certain number of detection messages to the other 9 servers in each detection period.

And S102, receiving the current response message fed back by each node to be detected in response to the current detection message.

In the embodiment of the invention, the detection node receives the current response message fed back by each node to be detected responding to the current detection message.

In the embodiment of the invention, after the node to be detected receives the corresponding current detection message, the node to be detected forms the same number of current response messages and feeds back the current response messages to the detection node. Because the node to be detected has a link fault with the detection node, the number of the current detection messages received by the node to be detected and the number of the current detection messages sent by the detection node may be inconsistent.

S103, determining a communication link detection result between each node to be detected based on the current response message and the current detection message.

In the embodiment of the invention, the detection node determines the detection result of the communication link between the detection node and each node to be detected based on the current response message and the current detection message.

In the embodiment of the invention, the detection node can calculate the packet loss rate through the current response message and the current detection message, and if the packet loss rate is greater than the packet loss rate threshold, the communication link detection result of the link abnormity between the corresponding node to be detected and the detection node is determined. And if the packet loss rate is not greater than the packet loss rate threshold, determining a communication link detection result that the link between the corresponding node to be detected and the detection node is normal.

In the embodiment of the invention, the detection node can also obtain the time delay information corresponding to the current response message, and if the time delay information is greater than the time delay threshold, the communication link detection result of the link abnormity between the corresponding node to be detected and the detection node is determined. And if the time delay information is not greater than the time delay threshold, determining a communication link detection result that the link between the corresponding node to be detected and the detection node is normal.

The communication link includes a physical link and a data link, the physical link refers to a section of physical line from one node to an adjacent node, and there is no other switching node in the middle. When data communication is carried out, a path between two servers is often formed by connecting a plurality of links in series. Data links refer to physical lines as well as communication protocols necessary to control the transmission of such data. The hardware and software that implements these protocols is added to the link to be the data link. The data links are also referred to as logical links.

S104, when the communication link detection result represents that the link of the target node is abnormal, modifying the service message based on a preset address resolution protocol table by loading a preset program to obtain a target message and sending the target message to the target node; the address resolution protocol table contains the sending rule information between each node to be detected and the address resolution protocol table is determined by the detection message in the detection period before the current detection period.

In the embodiment of the invention, when the communication link detection result represents that the link of the target node is abnormal, the detection node modifies the service message based on the preset address resolution protocol table by loading the preset program to obtain the target message to send to the target node. The address resolution protocol table contains the sending rule information between each node to be detected and the address resolution protocol table is determined by the detection message in the detection period before the current detection period.

In the embodiment of the invention, when the communication link detection result represents that the target node link is abnormal, the detection node loads a preset program. The detection node determines a switch forwarding rule based on the address resolution protocol table, and determines the replacement address information corresponding to the target node in the address resolution protocol table. And the detection node responds to a preset program and modifies the address information in the service message sent to the target node into the replacement address information according to the forwarding rule of the switch so as to obtain the target message.

Table one: address resolution protocol table

For example, in combination with table one, since the second source physical address information corresponding to host-B is inconsistent and the source physical address information of host-C is inconsistent, the probe node may determine that the switch forwarding rule is a source-destination address forwarding algorithm. At this time, when the target node is host-B, the probe node may determine a replacement address information from the corresponding source physical address information or the second source physical address information. The detection node replaces the source address information or the destination address information in the service message by using the replacement address information to form a target message and sends the target message to the host-B.

In the embodiment of the invention, the detection node sends a certain number of first detection messages to each node to be detected based on the constructed first virtual address information in the first detection period. Wherein the first detection period is before the current detection period. The detection nodes receive the first response message fed back by each node to be detected in response to the first detection message. The detection node constructs an address resolution protocol table based on the first detection message and the first response message.

In the embodiment of the invention, the first detection period is positioned before the current detection period, and the communication link of each node to be detected is normal. The detection node sends a first detection message to each node to be detected in a first detection period, and each node to be detected can also feed back the same number of first response messages to the detection node due to the normal communication link. And the first detection message and the first response message are in one-to-one correspondence.

In the embodiment of the invention, the detection node constructs each row of the address resolution protocol table based on the source physical address information and the local aggregation network port identification contained in each first detection message of each node to be detected, the second source physical address information contained in the corresponding first response message, the corresponding node identification to be detected, the corresponding network port identification of the node to be detected and the aggregation network port information of the corresponding node to be detected, so as to obtain the address resolution protocol table.

Illustratively, in connection with FIG. 3, the HOST A host includes ports NIC0 and NIC1.NIC0 and NIC1 form an aggregation network port band0.HOST B HOST includes ports NIC2 and NIC3.NIC2 and NIC3 form an aggregation network port band1. The construction process of the address resolution protocol table may include:

HOST a HOST agent randomly addresses a mac Address, and takes 8 consecutive Media Access Control Address addresses (mac) from the last byte +1, which may include: addresses (macA 0 to macA 7). The HOST A HOST acquires the mac of the HOST aggregation network port bond1 of the HOST B through the information table, and 8 current detection messages are constructed in the form of the mac of the macA 0-macA 7 → the mac of the HOST bond1 of the HOST B respectively and are sent to the bond1 of the HOST HOST B. Wherein, the current detection message includes: HOST a HOST identity and aggregation portal band0 identity and mac.

HOST B HOST agent also obtains 8 consecutive mac addresses (macB 0-macB 7) by the same random algorithm. When the HOST HOST B receives the current detection message of the HOST HOST A, the HOST A is respectively subjected to back packet in the format of macB 0-macB 7 → the aggregation network port bond0mac of the HOST HOSTA. And any network port of the HOSTB receives the current detection message to form a corresponding current response message for repackaging. Wherein, the current response message includes: HOST B HOST identity and corresponding portal identity. The 8 current probe messages of HOST a cover all member ports of HOST B's bond1. The HOST HOST A analyzes all the member ports of 8 bond1 covering the HOST HOST B, and can obtain the message source mac and the message destination mac of the NIC2 and the NIC3 which are sent to the HOST HOST B, and then the detection of the sending link of the HOST HOSTA → the HOST HOSTB is finished, and an address resolution protocol table is obtained. Otherwise, continuing the next step, and detecting by modifying the target mac.

The HOST HOST A reconstructs the current detection messages, and 8 current detection messages are constructed and sent to the bond1 of the HOST HOST B by respectively taking the mac of the HOST A bond0 as a source mac and taking macA 0-macA 7 as destination macs. When the HOST HOST B receives the current detection message of the HOST HOST A, the HOST HOSTA is respectively subjected to back packet in the format of macB 0-macB 7 → the bond0mac of the HOST HOSTA. The HOSTA host analyzes all the member ports of 8 bond1 covering the HOSTB host, and can obtain which two message source mac and destination mac of NIC2 and NIC3 sent to the HOSTB host should use, so that the detection of the sending link of the HOSTA host → HOSTB host is finished, and an address resolution protocol table is obtained.

In the embodiment of the invention, when the communication link detection result represents that the link is normal, the detection node unloads the preset program and sends the service message serving as the target message to the target node.

In the embodiment of the invention, when the communication link detection result represents that the link of the target node is abnormal, the detection node sends loading notification information to the target node, so that the target node loads a second preset program based on the loading notification information; and the target node constructs a target response message based on a second preset program and feeds back the target response message.

In the embodiment of the invention, after the detection node sends the target message to the target node, the detection node receives a target response message fed back by the target node in response to the target message.

In some embodiments, S101 to S102 shown in fig. 2 may also be implemented through S105 to S108, which will be described in conjunction with each step.

And S105, determining the number N of the network ports of each node to be tested in a local information table.

In the embodiment of the invention, the detection node determines the number N of the network ports of each node to be detected in a local information table. The information table stores the network port information and the aggregation network port information of each node to be tested. N is an integer of 1 or more.

S106, constructing M times of virtual address information of N according to a preset program instruction; m is an integer greater than 1.

In the embodiment of the invention, the detection node constructs M times of virtual address information of N according to a preset program instruction. M is an integer greater than 1.

In the embodiment of the invention, the detection node constructs a plurality of pieces of virtual address information according to the randomness of the preset program instruction.

For example, if the number of network ports of a certain node to be tested is 2, the probing node may construct 2 × 2=8 pieces of virtual address information corresponding to the node to be tested. In other embodiments, the probing node may also construct 10 pieces of virtual address information. The number of the virtual address information is larger than the number of the network ports of the corresponding nodes to be tested.

In the embodiment of the invention, the detection node receives M times of current detection messages of each node to be detected responding to N and K current response messages fed back. Wherein K is an integer.

In the embodiment of the invention, because the communication conditions between each node to be detected and the detection node are different, when a communication link between a certain node to be detected and the detection node is abnormal, the number of the current detection messages received by the node to be detected is not equal to the M power of N. The number of the K current response messages is determined by the number of the normal network ports of the node to be tested.

And S111, determining a switch forwarding rule based on the address resolution protocol table so as to determine the replacement address information in the address resolution protocol table.

In the embodiment of the invention, the detection node determines the forwarding rule of the switch based on the address resolution protocol table so as to determine the replacement address information in the address resolution protocol table.

In the embodiment of the invention, the detection node determines the forwarding rule of the switch based on the source physical address information and the second source physical address information of each node to be detected in the address resolution protocol table. The detection node determines the replacement address information of the corresponding switch forwarding rule in the address resolution protocol table.

In the embodiment of the invention, if the source physical address information of each node to be detected in the address resolution protocol table is inconsistent, the detection node obtains the switch forwarding rule as a source address forwarding algorithm. And if the second source physical address information of each node to be detected in the address resolution protocol table is inconsistent, the detection node obtains the switch forwarding rule as a destination address forwarding algorithm. And if the source physical address information and the second source physical address information of each node to be detected in the address resolution protocol table are inconsistent, the detection node obtains a switch forwarding rule as a source-destination address forwarding algorithm.

In the embodiment of the invention, the detection node determines the corresponding target source physical address information and the target second source physical address information in the address resolution protocol table through the identification of the target node contained in the service message. The detection node determines replacement address information in the target source physical address information and the target second source physical address information based on a switch forwarding rule; and the replacement address information is address information corresponding to the network port with the minimum load of the target node.

If the switch forwarding rule is a source address forwarding algorithm, the detection node determines the replacement address information in the target source physical address information. And if the switch forwarding rule is a destination address forwarding algorithm, the detection node determines the replacement address information in the target second source physical address information. If the switch forwarding rule is a source destination address forwarding algorithm, the detection node may determine the replacement address information from the target source physical address information and the target second source physical address information.

In the embodiment of the invention, the detection node responds to the preset program, and replaces the source address information or the destination address information in the service message by using the replacement address information according to the forwarding rule of the switch to obtain the target message so as to send the target message to the target node.

If the switch forwarding rule is a source address forwarding algorithm, the detection node replaces the source address information in the service message with the replacement address information. If the switch forwarding rule is a destination address forwarding algorithm, the detection node replaces the destination address information in the service message by using the replacement address information. If the switch forwarding rule is a source-destination address forwarding algorithm, the detection node replaces the source address information or the destination address information in the service message with the replacement address information.

In the embodiment of the invention, when the detection node detects the link failure of the target node, the forwarding rule of the switch is determined through the address resolution protocol table, the available replacement address information corresponding to the target node is determined in the address resolution protocol table, and the source address or the destination address in the service message is modified by utilizing the replacement address information, so that the effect of sending the target message to the target node is obtained.

Please refer to fig. 4, which is a schematic diagram illustrating an optional effect of the data processing method according to the embodiment of the present invention.

In the embodiment of the invention, all servers in the network system ping each other, and each server sends the detection message to other servers. Each server periodically (such as every second or every minute) sends a first detection message through the constructed virtual address information, and determines an address resolution protocol table based on a first response message fed back. When the server a detects the packet loss rate or the time delay between the server a and the network port of the server B through the current detection message and the current response message, if the packet loss rate or the time delay is continuously greater than the threshold th1 within a given time period T, the link is considered to be sub-healthy, and if the packet loss rate or the time delay is continuously greater than the threshold th2, the link is considered to be failed. When the server a detects a link failure/sub-health between the network port A1 and the network port B1, the control center of the probe node determines a learned virtual mac address in the address resolution protocol table for topology routing (a message using the mac address as a source mac or a destination mac is forwarded to a network port healthy by the server B, such as the network port B2, by the switch). Wherein, the address resolution protocol table comprises: the corresponding relation 1: a source port A1, a source mac1 and a destination port B1; the corresponding relation 2: source port A2, source mac2, destination port B2. Server a now notifies server B to load the eBPF programs (TC and XDP). Server a selects a virtual mac address that can be hashed to a healthy destination port, such as port B2. The server A modifies the source mac or the destination mac in the service message through the eBPF program and redirects the service message to a normal port, such as the port A2. After receiving the target message, the server B (e.g., port B2) detects a source mac address or a destination mac address in the target message by using the eBPF, and if the source mac address or the destination mac address is a special mac address for link switching, modifies the source mac address of the target message and restores the source mac address or the destination mac address to a real source mac address or a real destination mac address. When server a detects that the link failure/sub-health has been restored, the eBPF process is unloaded, i.e., the communication link can be restored.
