With the development of virtualization technology, three-layer networking is generated: a physical layer, a virtual layer, and an application layer. Although the special requirements of operators on the network are well met by the virtualization three-layer networking, the positioning and recovery of service faults are complex compared with the traditional network, and the requirements for rapid positioning and recovery of faults cannot be met by a pure manual mode.
In the related art, the conditions of network failure, packet loss and the like are determined end to end, for example, it can only be determined whether the network failure, packet loss and the like occur between a source node and a sink node, and it cannot be quickly determined which layer, which link and which device the network failure occurs on, which prolongs the time affected by the network failure and generates an unpredictable loss to an operator.
Based on this, the embodiments of the present invention provide a method, an apparatus, an electronic device, and a storage medium for determining a message transmission path fault, which can accurately locate a specific location where a fault occurs in a network, and determine a specific transmission link and a specific device where a network fault occurs.
For facilitating those skilled in the art to understand the embodiment of the present invention, the following first describes the architecture of the virtualized three-tier network provided in the embodiment of the present invention.
Fig. 1 is a schematic view of an application scenario of a method for determining a failure of a packet transmission path according to an embodiment of the present invention. Referring to fig. 1, an application scenario of the method for determining a message transmission path fault provided in the embodiment of the present invention includes a virtualized network, where the virtualized network adopts a three-layer networking architecture and includes a physical layer, a virtual layer, and an application layer.
In the above-described virtualized network, the physical layer includes a router 100, an EOR (End of Row) switch 110, a TOR (Top of Rack) switch 120, and a host 130.
In the above virtualization network, the virtual layer includes the virtual switch 140 and the virtual machine 150, the virtual machine 150 is deployed in the host 130, and the physical port of the host 130 and the virtual machine port of the virtual machine 150 can be managed through the virtual switch 140.
In the above-described virtualized network, the application layer includes various types of network elements 160, and various virtual machines 150 responsible for different functions are provided in the network elements 160.
A network element 160 may include multiple virtual machines 150, different virtual machines 150 may be deployed on the same host 130 or on different hosts 130, one host 130 may link multiple TOR switches 120, and one TOR switch 120 may link multiple EOR switches 110. Therefore, there are multiple optional message transmission paths between the sending device and the receiving device. It is to be understood that the sending device refers to a specific sending location, such as a network element, an intra-network element module, a service, a microservice or software, etc.
Fig. 2 is a schematic flowchart of a method for determining a failure of a packet transmission path according to an embodiment of the present invention. Referring to fig. 2, the method for determining a failure of a packet transmission path according to the embodiment of the present invention includes the following steps:
step S210, determining a transmission path of the target packet.
In some embodiments, based on the virtualized three-tier networking, a transmission path of the target packet includes a virtual node and a physical node, where the virtual node includes a virtual machine, and the physical node includes at least one of: the system comprises a host, a TOR switch, an EOR switch and a router; the node ports passed by the transmission path comprise a virtual machine port, a host incoming port, a host outgoing port, a TOR switch incoming port, a TOR switch outgoing port, an EOR switch incoming port, an EOR switch outgoing port, a router incoming port and a router outgoing port.
It can be understood that, based on the above virtualized three-layer networking, a transmission path of a target packet from a sending device to a receiving device is different, and nodes and node ports included in the transmission path are also different, for example, a target packet sent from a sending device passes through a virtual machine and returns to a receiving device when reaching a host, that is, the transmission path of the target packet includes a node: virtual machine, and node port: the virtual machine port, or alternatively, a target packet sent from the sending device, passes through the virtual machine and the host, and returns to the receiving device when reaching the TOR switch, that is, a transmission path of the target packet includes a node: virtual machine, host and TOR switch, and node port: in addition, the target message may also be returned to the receiving device at the EOR switch or the router, which is not described herein again.
In some embodiments, determining the transmission path of the target packet includes obtaining packet information of the target packet, where the packet information includes at least one of: a message location characteristic, a message service characteristic, and a message Internet Protocol (IP) characteristic; and determining a transmission path of the target message according to the message information.
The message location characteristics include, for example, sending equipment, receiving equipment, and the like, and it should be noted that the sending equipment refers to a specific location for sending a message, such as a network element, an intra-network element module, a service, a micro-service, or software.
Illustratively, the message service characteristics include, user, service type, and the like.
Illustratively, the packet IP characteristics include a source destination address, a source destination port, a protocol type, virtual Routing Forwarding (VRF), and the like.
It should be noted that, in the foregoing embodiment, determining, according to the message information, a transmission path of the target message may include: determining transmission paths of target messages at different sending positions according to the message position characteristics; or, according to the message service characteristics, determining the transmission path of a specific service message; or, according to the IP characteristics of the message, determining a transmission path of the target message from the sending equipment to the receiving equipment; the transmission path of the target message from the sending device to the receiving device can be determined according to any combination of message position characteristics, message service characteristics and message IP characteristics. According to different message information, transmission paths containing different information of different target messages can be determined, which is not listed herein. It should be understood that the transmission path defined herein includes the node and node port information on the transmission path.
Before determining the transmission path of the target message according to the message information, the embodiment of the present invention may further include the following steps:
and acquiring the adjacency relation of each node in the network, and determining an optional transmission link in the network according to the adjacency relation of each node.
It will be appreciated that each node in the network comprises nodes in the physical, virtual and application layers of a virtualized three-layer network as described above, i.e. the optional transmission link is a link comprising a physical, virtual and application layer three-layer network.
In a specific embodiment, according to the message position characteristic position, the message service information and the message IP characteristic, a virtual machine which interacts with the outside in the message sending equipment is determined, and then the relation between the application layer and the virtual layer is determined. According to the virtual machine which interacts with the outside in the message sending equipment, the host where the virtual machine is located is determined, and the contact between the virtual layer and the physical layer can be determined. Thus, the links between physical layer, virtual layer and application layer three-layer networking can be determined.
In another specific embodiment, based on the above virtualized three-Layer networking, referring to fig. 4, fig. 4 is a schematic structural diagram of physical devices in a physical Layer provided in the embodiment of the present invention, in which a router 200, an EOR switch 210, a TOR switch 220, a host 230, a Link Layer Discovery Protocol (LLDP) are started, a device identification number (session identification) and a device Port identification number (Port ID) of the host are notified to each other, and an adjacent relationship between the devices may be stored as follows:
the host 230 stores the adjacency relationship with the TOR switch 220 adjacent thereto.
It should be noted that, in the above embodiment, the optional transmission link between the acknowledgement host and the TOR switch may be: acquiring the Chassis ID of opposite-end equipment of the host and the Port ID of an opposite-end Port, comparing the acquired Chassis ID with the Chassis IDs of all TOR switches in a physical layer, after matching, comparing the acquired Port ID with the Port IDs of all ports of the TOR switches, and if the acquired Port ID and the Port IDs of all ports of the TOR switches are the same, the two ports are linked by a link.
It should be noted that, in the above embodiment, the optional transmission link between the TOR switch and the EOR switch may be: acquiring the Chassis ID of opposite-end equipment of the TOR switch and the Port ID of an opposite-end Port, comparing the acquired Chassis ID with the Chassis IDs of all EOR switches in a physical layer, after matching, comparing the acquired Port ID with the Port IDs of all ports of the EOR switches matched, and if the Port IDs are the same, enabling the two ports to have link connection. In addition, the above steps are also applicable to confirm the optional transmission link between the EOR switch and the router, and are not described herein again. Thus, the link between physical devices within the physical layer may be determined.
It can be understood that, a link between the sending device and the receiving device may change, a virtual machine in a network element of the application layer may migrate to a different host, and links between the host, the TOR switch, the EOR switch, and the router change, so that the link between the sending device and the receiving device is uncertain, and when the failure detection of the packet transmission path is performed again, the adjacency relation of each node in the network is obtained again, and the optional transmission link in the network is re-determined according to the adjacency relation of each node.
It should be understood that, determining the link between the physical devices in the physical layer may also be, when an instruction interface is opened between the physical devices, by obtaining configured device configuration information and message information, finding the outgoing interface and next hop information of each physical device, and finally forming a transmission path of the message between the physical devices.
In the embodiment of the present invention, determining a transmission path of a packet according to packet information includes: and determining a transmission path of the target message from the optional transmission link according to the message information.
It should be noted that, based on the above virtualization three-layer networking, the optional transmission link includes all transmission paths of the physical layer, the virtual layer, and the application layer, and the target packet is sent from the sending device and may return to the receiving device from the host, the TOR switch, the EOR switch, or the router, so that the actual transmission path of the target packet may not completely include all nodes and node ports on the optional transmission path.
Step S220, obtaining a target identifier corresponding to the target packet. It should be noted that the target identifier may be set in a data field of the target packet, or may be set in an identifier field of the target packet.
Step S230, determining the statistical number of the target packets corresponding to each node port through which the transmission path passes according to the target identifier.
And according to the target identifier arranged in the target message, counting the message quantity of the target message corresponding to the target identifier at each node port passed by the transmission path.
It is understood that, based on the above-described virtualized three-tier networking, the node ports through which the transmission path passes may be a virtual machine port, a host ingress port, a host egress port, a TOR switch ingress port, a TOR switch egress port, an EOR switch ingress port, an EOR switch egress port, a router ingress port, and a router egress port. For example, when a target message is sent from a sending device, a TOR switch is reached and returns to a receiving device, node ports through which a transmission path of the target message passes include a virtual machine port, a host ingress port, a host egress port, a TOR switch ingress port and a TOR switch egress port, and thus, the statistical number of the target message of corresponding target identifiers at the virtual machine port, the host ingress port, the host egress port, the TOR switch ingress port and the TOR switch egress port is determined.
In some embodiments, the target identifier is set in a Differentiated Services Code Point (DSCP) field of the target packet, and determines the statistical number of the target packet corresponding to each node port through which the transmission path passes, where, referring to fig. 3, the method includes:
step S310, for each node port passed by the transmission path, respectively obtaining the message received by the node port;
step S320, when the DSCP field in the message received by the node port is a preset field value, determining the message as a target message;
step S330, counting the number of the target messages received by the node ports to obtain the counted number of the target messages corresponding to the node ports.
Based on the above-mentioned virtualized three-layer networking, the description will be given by taking an example in which a target message is sent from a sending device and returns to a receiving device when arriving at a TOR switch. The node ports through which the transmission path of the target message passes include a virtual machine port, a host incoming port, a host outgoing port, a TOR switch incoming port and a TOR switch outgoing port, so that the messages received by the node ports are respectively acquired, when a DSCP field in the received messages is a preset field value, the messages are determined as the target messages, and then the number of the target messages received by the node ports is counted to obtain the counted number of the target messages corresponding to the node ports.
It should be noted that the DSCP uses 6 bits in the TOS flag byte of the service class of each datagram IP header to classify the service class and prioritize the service, where the DSCP value ranges from 0 to 63. The DSCP value of the message is modified to mark the message, so that the function of identifying the target message is achieved, and meanwhile, the DSCP value of the message is modified, so that the length of the target message cannot be increased, and data information carried by the target message cannot be influenced.
It should be understood that the data field or other identification field of the target packet is modified, so that the target packet carries the target identification, and the target packet can be identified as such. When the target identifier is set in the data field or other identifier fields of the target packet, determining the statistical number of the target packets corresponding to each node port through which the transmission path passes is also applicable to the above method steps, and details are not repeated here.
In some embodiments, the last two bits of the DSCP field of the target packet are both fixed values of 1.
And modifying the DSCP value of the target message to mark the message, thereby achieving the purpose of identifying the target message. In order to more accurately identify the target message and avoid the conflict with the commonly used DSCP value, when the target message is modified, the last two bits of the DSCP field are both fixed values of 1.
It should be noted that the last two bits refer to 2 bits of the DSCP field except for 6 bits used for dividing the service class, specifically, two bits of the last two bits of the DSCP field, for example, the DSCP field is set to 101111B, that is, the DSCP value is 47, or the DSCP field is set to 110111B, that is, the DSCP value is 55.
After determining the transmission path of the packet and before determining the statistical number of the target packets respectively corresponding to each node port through which the transmission path passes, the embodiments of the present invention may further include: and sending a message modification request to an initial node passed by the transmission path so as to modify the target message through the initial node according to the message modification request, so that the target message carries a target identifier.
After the transmission path of the message is determined, a message modification request is sent to an initial node passed by the transmission path, so that the initial node modifies a target message according to the message modification request, the target message carries a target identifier, and then the statistical quantity of the target message corresponding to each node port passed by the transmission path can be determined.
It will be appreciated that the originating node through which the transmission path passes may be a node in the physical, virtual and application layers of a virtualized three-layer network as described above. Optionally, the originating node modifies the target packet according to the packet modification request, which may be modifying a data field of the target packet so that the target packet carries the target identifier, or modifying an identifier field of the target packet so that the target packet carries the target identifier.
Step S240, determining a location of the transmission path where the failure occurs according to the node port meeting a first condition, where the first condition is that the statistical number of the target packets corresponding to the node port is smaller than a preset number threshold.
And determining the position of the fault in the transmission path, namely determining the specific transmission link and equipment with the network fault according to the relation between the statistical quantity of the target messages corresponding to the node ports and the preset quantity threshold, namely whether the statistical quantity of the corresponding target messages is smaller than the preset quantity threshold.
It can be understood that the preset number threshold is the total number of target packets carrying the target identifier, and in a specific embodiment, the preset number threshold is the total number of target packets carrying the target identifier, which is sent by an initial node through which a transmission path passes through modifying a DSCP field of the target packet according to a packet modification request, that is, the total number of target packets whose DSCP is set to a specific value.
Based on the above-mentioned virtualized three-layer networking, the description will be given by taking an example in which a target message is sent from a sending device and returns to a receiving device when reaching an EOR switch. The node ports through which the transmission path of the target message passes include a virtual machine port, a host ingress port, a host egress port, a TOR switch ingress port, a TOR switch egress port, an EOR switch ingress port and an EOR switch egress port, and the embodiments of the present invention determine the statistical number of the target message of the node ports, and then determine the position of a transmission fault in the transmission path, including the following conditions:
if the number of the target packets carrying the target identifier is 1200, that is, the preset number threshold is 1200, the statistical number of the target packets at the virtual machine port is 1200, the statistical number of the target packets at the host ingress port is 1200, the statistical number of the target packets at the host egress port is 1100, and the statistical number of the target packets at the other node ports is 1100, it may be determined that the location where the failure occurs in the transmission path is the host device in the physical layer.
For another example, if the number of the target packets carrying the target identifier is 1400, that is, the preset number threshold is 1400, the statistical number of the target packets at the ports of the virtual machine is 1400, the statistical number of the target packets at the outgoing ports of the host is 1400, the statistical number of the target packets at the incoming ports of the TOR switch is 1300, and the statistical number of the target packets at the ports of other nodes is 1300, it can be determined that the failure position in the transmission path is on the link from the host to the TOR switch in the physical layer.
For another example, if the number of target packets carrying the target identifier is 1600, that is, the preset number threshold is 1600, the statistical number of target packets at the virtual machine port is 1500, and the statistical number of target packets at other node ports is 1500, it may be determined that the location where the failure occurs in the transmission path is on the link from the application layer to the virtual layer.
When a failure occurs in the transmission path at another position of the virtualized three-layer networking, the above method steps are also applicable, and are not described herein again.
In the above embodiments, the descriptions of the respective embodiments are focused, and for parts that are not described or recited in detail in a certain embodiment, reference may be made to the descriptions of other embodiments.
In the embodiment of the invention, the transmission path of the target message is determined, the target identifier corresponding to the target message is obtained, the statistical quantity of the target message corresponding to each node port through which the transmission path passes is determined according to the target identifier, and the position where the fault occurs in the transmission path is positioned according to the relation between the statistical quantity of the target message corresponding to the node port and the preset quantity threshold value, namely whether the statistical quantity of the corresponding target message is smaller than the preset quantity threshold value, namely the specific transmission link and equipment where the network fault occurs are determined.
