So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In addition, the following embodiments are provided as partial embodiments for implementing the present invention, not all embodiments for implementing the present invention, and the technical solutions described in the embodiments of the present invention may be implemented in any combination without conflict.
It should be noted that the terms "first \ second \ third \ fourth" related to the embodiments of the present invention are merely used for distinguishing similar objects, and do not represent a specific ordering for the objects, and it should be understood that "first \ second \ third \ fourth" may exchange a specific order or sequence order if allowed. It should be understood that the first, second, third, fourth "distinguishing objects may be interchanged under appropriate circumstances such that embodiments of the invention described herein may be practiced in sequences other than those illustrated or described herein.
In the embodiment of the present invention, the electronic device may include, but is not limited to, any device having information or message sending and receiving functions, such as a core device, a switching device, and an aggregation device inside a data center network.
Example one
As shown in fig. 5, an implementation process of a network link detection method according to an embodiment of the present invention includes the following steps:
step S101, a first electronic device receives attribute information of a second electronic device;
wherein the port attributes include at least: the types of the ports, such as an uplink port and a downlink port, a row port and a column port, an internal connection port and an external connection port, and the like; the position information is expressed by node coordinates X and Y, and the position information at least includes: the layer information, or the column information, or the row information of the electronic equipment in the data center network.
Specifically, the first electronic device receives attribute information of the second electronic device sent by the second electronic device through a message or information.
Taking an example that the second electronic device sends the attribute information of the second electronic device through a message, as shown in fig. 6, the format of the message includes: network architecture type, port type, node coordinate X and node coordinate Y; wherein the network architecture type comprises: multilayer architecture, FATTREE, matrix DCN and DCELL. The port types do not have the same meaning in different network architecture types; in a data center network of a multi-layer architecture and a data center network of FATTREE, the port types comprise an upstream port and a downstream port; in a data center network of Matrix DCN, the port types include a row interface and a column interface; in a data center network of DCELL, the port types include inline ports and external links. The node coordinate X and the node coordinate Y are used for representing the position information of the electronic equipment, and the meanings of the node coordinate X and the node coordinate Y in different network architecture types are different; in the data center network of the multi-tier architecture and the data center network of the FATTREE, the node coordinate X includes: the hierarchy and the container identification, the value range of the hierarchy is 0-255, and 0 represents a host layer; the value range of the container identifier is 0-255; the value range of the node coordinate Y is 0-65535. In a data center network of Matrix DCN, the value range of a node coordinate X is 0-65535, and 0 represents a head-of-line switch; the value range of the node coordinate Y is 0-65535, and 0 represents a head switch. In the data center network of DCELL, the node coordinates X include: the hierarchy and the container identification, the value range of the hierarchy is 0-255,0 represents the port of the innermost layer, and the value range of the container identification is 0-255; the value range of the node coordinate Y is 0-65535.
The message may also be extended based on an existing protocol message, taking the extension based on an LLDP message as an example, the format of the LLDP message is shown in fig. 7, and the "custom information" is an extended message carrying attribute information of the second electronic device; the network architecture type and the port type in the extended message both occupy 1 byte, and the node coordinate X and the node coordinate Y in the extended message both occupy 2 bytes.
Here, the attribute information of the second electronic device may be directly configured on the second electronic device, or may be sent to the second electronic device by a management unit, a control unit, or the like inside a data center network that is independent of the second electronic device; the attribute information of the second electronic device at least includes a port attribute of the second electronic device or location information of the second electronic device.
Step S102, based on the attribute information of the second electronic device, detecting a network link between the first electronic device and the second electronic device according to a preset strategy;
specifically, the first electronic device matches its own attribute information with the attribute information of the second electronic device according to a preset strategy to obtain a matching result; the first electronic device detects whether the network connection relationship between the first electronic device and the second electronic device is correct or not based on the matching result.
Here, the preset policy may be a detection policy carried in the received attribute information of the second electronic device, or may also be a detection policy stored in the first electronic device itself, where each detection policy corresponds to a network architecture type.
Wherein the preset strategy comprises: two electronic devices having the same port type cannot have a link relationship therebetween, i.e., cannot be interconnected; two electronic devices in the same layer of the data center network cannot have a link relationship, namely cannot be interconnected; two electronic devices across layers cannot be intercommunicated, namely only two electronic devices positioned between adjacent layers of the data center network can be intercommunicated; the electronic device at the head of the row may have a link relationship with the electronic device at the row, and the electronic device at the head of the column may have a link relationship with the electronic device at the column; the preset policy further includes a link relationship between the self-defined Y coordinates, for example, a link relationship may be defined between electronic devices with an odd Y coordinate, or a link relationship may be defined between electronic devices with an even Y coordinate, or a link relationship may be defined between an electronic device with an odd Y coordinate and an electronic device with an even Y coordinate, and the like.
Taking the attribute information of the second electronic device as location information as an example, when it is determined that the matching result is that the first electronic device and the second electronic device are located in the same layer network based on the location information of the first electronic device and the location information of the second electronic device, a network link relationship error between the first electronic device and the second electronic device is detected.
Taking the attribute information of the second electronic device as a port attribute as an example, and determining that the matching result is that the port attribute of the first electronic device is the same as the port attribute of the second electronic device based on the port attribute of the first electronic device and the port attribute of the second electronic device according to the port attribute of the port, detecting a network link relation error between the first electronic device and the second electronic device; namely, when the port type of the first electronic device is the same as the port type of the second electronic device, the network link relationship between the first electronic device and the second electronic device is incorrect.
Taking the example that the attribute information of the second device includes both the location information and the port attribute, the location information of the first electronic device needs to be matched with the location information of the second electronic device to obtain a first matching result; matching the port attribute of the first electronic equipment with the port attribute of the second electronic equipment to obtain a second matching result; and determining the network link relation between the first electronic equipment and the second electronic equipment by combining the first matching result and the second matching result. And determining that the network link relationship between the first electronic device and the second electronic device is correct only when the first matching result and the second matching result both represent that the network link relationship between the first electronic device and the second electronic device is correct. When any one of the first matching result and the second matching result represents that the network link relationship between the first electronic device and the second electronic device is wrong, the network link relationship between the first electronic device and the second electronic device can be determined to be wrong.
Example two
As shown in fig. 8, an implementation flow of a method for detecting a network link according to a second embodiment of the present invention is similar to the method shown in fig. 5, except that, in step S102, after the first electronic device detects a network link relationship error between the first electronic device and the second electronic device, the method further includes:
step S103, reporting the wrong network link by the first electronic equipment;
specifically, the first electronic device sends information to a designated functional unit; the information is used for indicating that the network link relation of the first electronic equipment and the second electronic equipment is wrong; the information may also be used to indicate a reason for the network link relation error.
The functional unit may be an electronic device or module inside a data center network, or may be a remote electronic device or module independent of the data center network; the information may be alarm information or common communication information.
Third embodiment as shown in fig. 9, a third embodiment of the present invention is a process for implementing a network link detection method, including the following steps:
step S201, a first electronic device receives attribute information of a second electronic device;
wherein the port attributes include at least: the types of the ports, such as an upstream port and a downstream port, a row interface and a column interface, an internal connection port and an external connection port, and the like; the position information is expressed by node coordinates X and Y, and the position information at least comprises: the layer information, the column information or the row information of the electronic equipment in the data center network.
Specifically, the first electronic device receives attribute information of the second electronic device sent by the second electronic device through a message or information.
Taking an example that the second electronic device sends the attribute information of the second electronic device through a message, as shown in fig. 6, the format of the message includes: network architecture type, port type, node coordinate X and node coordinate Y; wherein the network architecture type comprises: multilayer architecture, FATTREE, matrix DCN and DCELL. The port types do not have the same meaning in different network architecture types; in a data center network of a multi-layer architecture and a data center network of FATTREE, the port types comprise an upstream port and a downstream port; in a data center network of Matrix DCN, the port types comprise row interfaces and column interfaces; in a data center network of DCELL, the port types include inline ports and external links. The node coordinate X and the node coordinate Y are used for representing the position information of the electronic equipment, and the meanings of the node coordinate X and the node coordinate Y in different network architecture types are different; in the data center network of the multi-tier architecture and the data center network of the FATTREE, the node coordinate X includes: the hierarchy and the container identification, the value range of the hierarchy is 0-255, and 0 represents a host layer; the value range of the container identifier is 0-255; the value range of the node coordinate Y is 0-65535. In a data center network of Matrix DCN, the value range of a node coordinate X is 0-65535, and 0 represents a head-of-line switch; the value range of the node coordinate Y is 0-65535, and 0 represents the head switch. In the data center network of DCELL, the node coordinates X include: the hierarchy and the container identification, the value range of the hierarchy is 0-255,0 represents the port of the innermost layer, and the value range of the container identification is 0-255; the value range of the node coordinate Y is 0-65535.
The message may also be extended based on an existing protocol message, taking the extension based on an LLDP message as an example, the format of the LLDP message is shown in fig. 7, and the "custom information" is an extended message carrying attribute information of the second electronic device; the network architecture type and the port type in the extended message both occupy 1 byte, and the node coordinate X and the node coordinate Y in the extended message both occupy 2 bytes.
Here, the attribute information of the second electronic device may be directly configured on the second electronic device, or may be sent to the second electronic device by a management unit, a control unit, or the like inside a data center network that is independent of the second electronic device; the attribute information of the second electronic device at least includes a port attribute of the second electronic device or location information of the second electronic device.
Step S202, the first electronic equipment sends the attribute information of the first electronic equipment and the attribute information of the second electronic equipment to a judgment system;
here, the decision system is an electronic device or a module or a functional unit having a communication function and an information processing function, which is independent of the data center network.
Step S203, the decision system detects a network link between the first electronic device and the second electronic device according to a preset policy;
specifically, the judgment system matches the attribute information of the first electronic device with the attribute information of the second electronic device according to a preset strategy to obtain a matching result; and detecting whether the network link relation between the first electronic equipment and the second electronic equipment is correct or not based on the matching result.
The preset policy may be sent to the decision system by the first electronic device, may also be pre-stored in the decision system, or may be obtained by any other decision system, which is not specifically limited herein.
Here, a specific implementation manner of the decision system detecting the network link between the first electronic device and the second electronic device is the same as the specific implementation manner of the first electronic device detecting the network link between the first electronic device and the second electronic device in step S102, and details are not repeated here.
Example four
As shown in fig. 10, an implementation flow of a method for detecting a network link according to four embodiments of the present invention is similar to the method shown in fig. 9, except that after step S203, the method further includes:
step S204, the judgment system processes the wrong network link;
specifically, the decision system sends a blocking instruction to a data center network, where the blocking instruction is used to instruct the data center network to disconnect a detected erroneous network link; or the judgment system sends alarm information to a manager of the data center network, wherein the alarm information is used for indicating wrong network links; the alarm information is also used for indicating the reason of the network link relation error.
EXAMPLE five
As shown in fig. 11, a flow for implementing a method for detecting a network link according to a fifth embodiment of the present invention includes the following steps:
step S301, the virtual switch (vSwitch) acquires the configuration information of the virtual switch;
here, the configuration information may be directly configured on the vSwitch, or may be sent to the vSwitch by another functional unit; taking the example that the decision system sends the configuration information to the vSwitch, as shown in fig. 12, where the vSwitch is a forwarding node in fig. 12, and the decision system sends the configuration information of the forwarding node to each forwarding node; and sending self configuration information among all forwarding nodes through an LLDP message.
Step S302, the vSwitch sends a detection message to opposite terminal equipment;
here, vSwitch can periodically send detection messages, and the period can be flexibly set according to needs; the vSwitch can also send a detection message when the trigger condition is met; the trigger condition may be a port UP (UP) of the vSwitch, or a change in configuration information of the vSwitch, or the like.
Step S303, after receiving the detection message sent by the vSwitch, the opposite terminal equipment performs network link detection based on the detection message;
specifically, the specific implementation manner of the network link detection performed by the peer device is the same as that in step S102 in the first embodiment, and is not described here again.
In the embodiment of the present invention, after detecting a network link relationship between the peer device itself and a vSwitch based on a detection packet sent by the vSwitch, the peer device may send the detection packet to the vSwitch when a trigger condition is met, or send the detection packet to the vSwitch periodically; or the detection message may not be sent to the vSwitch any more.
Based on the method for detecting network links described in the foregoing embodiment, a network architecture shown in fig. 13 is taken as an example to describe in detail a wrong network link relationship.
The network architecture shown in fig. 13 is a variation of a multi-tier architecture combined with a FATTREE network architecture, which has both a hierarchy and different container units (PODs);
the preset strategy comprises the following steps: two devices of adjacent layers can have a network link relation; the uplink port of the equipment positioned at the lower layer is connected with the downlink port positioned at the upper layer; different PODs are connected by a network link to an upper layer.
The network links in the network architecture shown in fig. 13 are identified by dashed and solid lines, respectively; wherein, link 1, link 2, link 3 and link 4 are marked by dotted lines and are wrong network links; the network link identified by the solid line is the correct network link; the reasons for the network link error are:
1) Link 1 is a link between access device 1 (ac 1) and core device 2 (core 2), since ac1 is located at a layer in the network architecture that is not adjacent to the layer where core2 is located in the network architecture; thus, link 1 is an erroneous link.
2) Link 2 is a link between ac1 and ac2, since ac1 and ac2 are located at the same layer in the network architecture; thus, link 2 is an erroneous link.
3) Link 3 is a link between ac2 and aggregation device 3 (ag 3), and since ac2 and ag3 are located in different containers in the network architecture, different containers cannot be directly connected with each other; thus, link 3 is an erroneous link.
4) The link 4 is a link between ac5 and ag6, and the ac5 and the ag6 are uplink ports, while the ports of the same type are connected differently; thus, link 4 is an erroneous link.
Based on the method for detecting network links in the foregoing embodiments, the network architecture shown in fig. 14 is taken as an example to describe in detail the relationship of the network links that are wrong.
Based on the DCELL network architecture shown in fig. 14, the preset policies include: the devices in the same unit can only be connected through the inline port, namely, the host can only be connected with the switch; different units are connected through an external port, namely the units can be connected with other units only through the external port of the host; all the hosts in the same unit are connected with the switch; the external ports of the same tier of devices may be interconnected.
The network links in the network architecture shown in fig. 14 are identified by dashed and solid lines, respectively; wherein, link 1, link 2 and link 3 are marked by dotted lines and are wrong network links; the network link identified by the solid line is the correct network link; the reasons for the network link error are:
1) The link 1 is formed by interconnecting an inline port of the switch 1 (sw 1) with an inline port of the sw 2; since sw1 and sw2 belong to different containers respectively, the inline ports cannot be connected across the containers; thus, link 1 is an erroneous link.
2) The link 2 is a link between the sw1 and the host 2-1 through an external port; since the external port cannot connect to the device in the container, link 2 is the wrong link.
3) Link 3 host 0-0 and host 0-1 through the link between 1 layer of external ports through 0 layer of external ports, because the external ports of different layers can not be interconnected, link 3 is a wrong link.
In order to implement the foregoing method, an embodiment of the present invention further provides an electronic device, as shown in fig. 15, where the electronic device includes: a receiving module 10 and a detecting module 20; wherein the content of the first and second substances,
the receiving module 10 is configured to receive attribute information of a third electronic device; the attribute information of the third electronic device at least includes: port attributes of the third electronic device or location information of the third electronic device;
the detecting module 20 is configured to detect a network link between the electronic device and the third electronic device according to a preset policy based on the attribute information of the third electronic device.
In a specific embodiment, the detection module 20 is specifically configured to match the attribute information of the electronic device with the attribute information of the third electronic device according to a preset policy, so as to obtain a matching result;
detecting whether a network link between the electronic device and the third electronic device is correct based on the matching result.
In a specific embodiment, the detecting module 20 is specifically configured to detect a network link relationship error between the electronic device and the third electronic device when it is determined that the matching result is that the electronic device and the third electronic device are located in the same layer network based on the location information of the electronic device and the location information of the third electronic device; or the like, or, alternatively,
