Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail with reference to the accompanying drawings, and the described embodiments should not be construed as limiting the present application, and all other embodiments obtained by those skilled in the art without making any inventive effort are within the scope of the present application.
In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is to be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with one another without conflict.
In the following description, the terms "first", "second", "third" and the like are merely used to distinguish similar objects and do not represent a specific ordering of the objects, it being understood that the "first", "second", "third" may be interchanged with a specific order or sequence, as permitted, to enable embodiments of the application described herein to be practiced otherwise than as illustrated or described herein. In the following description, the term "plurality" refers to at least two.
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 application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the present application.
In the related art, for message transmission in a node cluster formed by 3 nodes, one method is to use Spanning-Tree Protocol (STP) to perform message transmission between nodes; however, when a message is transmitted between the first node and the third node using STP protocol, the message needs to pass through the second node, resulting in a decrease in the message transmission efficiency. The other method is to directly send the message between two nodes through a routing protocol; however, the routing protocol is a three-layer protocol, and if some application messages are two-layer messages, the two-layer messages cannot be forwarded through the routing protocol, so that the use of some applications is limited.
An embodiment of the present application provides a message processing method, and an optional processing flow of the message processing method, as shown in fig. 1, includes at least the following steps:
step S101, a first node in the ad hoc network determines the type of the message as a first type.
In some embodiments, a schematic diagram of an ad hoc network, as shown in fig. 2; the ad hoc network is formed by interconnecting physical interfaces corresponding to three nodes in pairs; two physical interfaces (also referred to as interfaces) on each node are added to the node's corresponding ad hoc bridge (also referred to as bridge). The three nodes in the ad hoc network are a first node, a second node and a third node respectively; the two physical interfaces on the first node are respectively used for transmitting messages with the second node and the third node; the two physical interfaces CA and CB on the first node are respectively added into a first network bridge corresponding to the first node, and the first network bridge can monitor the states of the two physical interfaces CA and CB on the first node. Wherein the physical interface may be a portal.
In some embodiments, the message is sent by a third node in the ad hoc network to the first node. The first type of message may include two types. One is a broadcast message, the other is a unicast message, and a destination media access control address (Media Access Control, MAC) carried in the unicast message is not in the media access control table of the first bridge corresponding to the first node.
In some embodiments, the first node, the second node, and the third node may each be a server; accordingly, the node cluster may be a server cluster. The first node may be connected to at least one first virtual machine, the second node may be connected to at least one second virtual machine, and the third node may be connected to at least one third virtual machine.
Step S102, the first node forwards the message to a second node in the ad hoc network and a first virtual machine corresponding to the first node according to the type of the message and the abnormal state of the first transmission link.
In some embodiments, the first transmission link is a transmission link between the second node and the third node, and is a transmission link constructed based on a BA interface of the second node and an AB interface of the third node.
In some embodiments, the abnormal state of the first transmission link may be any one or more of the following: 1) The network connection between the second node and the third node is broken. 2) The BA interface and/or the AB interface are in a damaged state. 3) The BA interface and/or the AB interface are off. 4) The second node and/or the third node is in a system closed state. Wherein, the BA interface and/or AB interface being in a closed state may refer to: the user manually closes one or both of the BA interface and the AB interface. The second node and/or the third node being in a system off state may refer to: the first node and/or the second node is/are in a shutdown state; the second node and/or the third node being in a system off state may also refer to: the first node and/or the second node is in a powered-down state.
In some embodiments, the abnormal state of the first transmission link may be sent by the second node and/or the third node to the first node.
In the implementation, if the BA interface in the second node is damaged or closed, the second node determines that the first transmission link is in an abnormal state, and sends a notification to the first node that the first transmission link is in an abnormal state. If the AB interface in the third node is damaged or closed, the third node judges that the first transmission link is in an abnormal state and sends a notification that the first transmission link is in the abnormal state to the first node. If the network connection between the second node and the third node is interrupted, the second node and the third node can both judge that the first transmission link is in an abnormal state, and the second node and the third node both send a notification to the first node that the first transmission link is in the abnormal state. If the second node is in the system-off state, the second node sends a notification to the first node that the first transmission link is in an abnormal state. If the third node is in the system-off state, the third node sends a notification that the first transmission link is in an abnormal state to the first node.
In the following, a specific implementation procedure of the message processing method provided in the embodiment of the present application is described by taking an example that a first transmission link is abnormal due to a connection interruption between a second node and a third node, and the third virtual machine sends a broadcast message to the second virtual machine. An alternative process flow diagram of the message processing method provided in the embodiment of the present application, as shown in fig. 3, at least includes the following steps:
in step S201, the second node and the third node send notification of the abnormal state of the first transmission link to the first node.
In some embodiments, if the connection between the second node and the third node is broken, the AB interface and the BA interface enter an abnormal state, and both the second node and the third node may send a notification of the abnormal state of the first transmission link to the first node.
Step S202, the third virtual machine sends a broadcast message to the third node.
In some embodiments, the third virtual machine may send the broadcast message to a third bridge corresponding to the third node.
In step S203, the third node forwards the broadcast message to the first node.
In some embodiments, a third bridge corresponding to the third node forwards the broadcast message to the first node.
In some embodiments, after receiving the broadcast packet sent by the third node, the first node stores a correspondence between the third virtual machine corresponding to the third node and an interface of the first bridge.
In some embodiments, the first node stores a correspondence of the third virtual machine to the interface of the first bridge in a MAC table of the first bridge; the interface of the first bridge is an interface (AC interface) for sending a broadcast message in the first bridge.
Step S204, the first node performs flooding forwarding on the broadcast message.
In some embodiments, the first node forwards the broadcast message to all devices and nodes connected to the first node. With respect to fig. 3, a first node forwards a broadcast message to a first virtual machine and a second node.
In step S205, the second node forwards the broadcast message to the second virtual machine.
In some embodiments, after receiving the broadcast message, the second node stores, in a MAC table of a second bridge corresponding to the second node, a correspondence between the first virtual machine and an interface of the second bridge corresponding to the second node; the interface of the second bridge is an interface (BC interface) for receiving the broadcast message in the second bridge.
In some embodiments, the second node performs flooding forwarding on the broadcast message, and because the first transmission link between the second node and the third node is abnormal, the second node forwards the message only to the second virtual machine.
In this embodiment, in step S204, after the first node forwards the broadcast message to the first virtual machine, the first virtual machine parses the broadcast message, determines that the destination MAC address carried in the broadcast message is not matched with the network protocol address of the first virtual machine, and then the first virtual machine ignores the broadcast message.
After the second virtual machine receives the broadcast message according to the message processing method shown in fig. 3, the alternative processing flow of the message processing method provided in the embodiment of the present application is processed, as shown in fig. 4, and at least includes the following steps:
in step S206, the second virtual machine sends a unicast response message to the second node.
In some embodiments, the second virtual machine parses the broadcast message, and determines that the destination MAC address carried in the broadcast message matches the network protocol address of the second virtual machine, and then the second virtual machine sends a unicast response message to the second node.
In step S207, the first node receives the unicast response message sent by the second node.
In some embodiments, after receiving the unicast reply message, the second node sends the unicast reply message to the first node through the BC interface according to the corresponding relationship between the first virtual machine and the BC interface stored in the MAC table of the second bridge.
In step S208, the first node sends the unicast reply message to the third node.
In some embodiments, after receiving the unicast reply message, the first node sends the unicast reply message to the third node through the CA interface according to the corresponding relationship between the third virtual machine stored in the MAC table of the first bridge and the CA interface.
In step S209, the third node forwards the unicast reply message to the third virtual machine.
In the embodiment of the present application, under the condition that a first transmission link between a second node and a third node is abnormal, based on the ad hoc network provided in the embodiment of the present application, the third node sends a broadcast message to a second virtual machine through the first node; the efficient transmission of the message is realized.
The foregoing describes the processing procedure of the further packet processing method provided in the embodiment of the present application, taking an example that there is an abnormality of a transmission link in the ad hoc network. The following describes a message processing method provided in the embodiment of the present application, taking as an example that each transmission link in the ad hoc network shown in fig. 2 is normal. As shown in fig. 5, another optional processing flow of the message processing method provided in the embodiment of the present application at least includes the following steps:
in step S301, the first node receives a message sent by the third node.
In some embodiments, after receiving the message sent by the third node, the first node stores, in a MAC table of the first bridge corresponding to the first node, a correspondence between the first virtual machine corresponding to the first node and the CA interface.
In some embodiments, the message received by the first node is a broadcast message; or the message received by the first node is a unicast message, and the destination MAC carried in the unicast message is not in the MAC table of the first network bridge
In step S302, the first node forwards the message only to the first virtual machine.
In the embodiment of the application, the first node does not perform flooding forwarding on the received message, that is, the first node does not forward the message to the second node connected with the first node, and only forwards the message to the first virtual machine connected with the first node.
In this embodiment of the present application, when all transmission links in an ad hoc network are in a normal state (may also be referred to as a state in which a message can be transmitted between any two nodes), when any node receives a first type of message sent by another node, the message is only forwarded to a virtual machine corresponding to the node, and forwarding between nodes is not performed through a physical interface. As an example, after the first node receives the message sent by the third node, the first node only forwards the message to the first virtual machine, and the first node does not forward the message to the second node. The first type of message is a broadcast message; or the first type message is a unicast message, and the destination MAC carried in the unicast message is not in the MAC table of the network bridge corresponding to the node receiving the message.
In some embodiments, if the destination MAC address carried in the packet matches the network protocol address of the first virtual machine, after step S302, the method further includes:
step S303, the first node receives the unicast response message sent by the first virtual machine.
In step S304, the first node forwards the unicast reply message to the third node.
In some embodiments, the first node forwards the unicast reply message to the third node through the CA interface according to the correspondence between the first virtual machine and the CA interface stored in step S301. And the third node forwards the unicast response message to the third virtual machine.
Taking the example that each transmission link in the ad hoc network shown in fig. 2 is normal, the detailed processing flow of the message processing method provided in the embodiment of the present application, as shown in fig. 6, at least includes the following steps:
in step S401, the third virtual machine sends a broadcast message to the third node.
In some embodiments, the destination MAC address carried in the broadcast packet matches a MAC address corresponding to the second node in the ad hoc network.
In step S402, the third node forwards the broadcast message to the first node and the second node.
In some embodiments, the broadcast message received by the third node is not sent by a node in the ad hoc network, but is sent by a virtual machine, and the third node performs flooding forwarding on the broadcast message.
In step S403, the first node forwards the broadcast message to the first virtual machine.
In some embodiments, after receiving the broadcast message, the first node stores a correspondence between the third virtual machine and the CA interface in the first bridge.
In step S404, the second node forwards the broadcast message to the second virtual machine.
In some embodiments, the second node stores, in the second bridge, a correspondence of the third virtual machine and the BA interface after receiving the broadcast message.
Step S405, the second virtual machine sends a unicast response message to the second node.
In some embodiments, if the second virtual machine determines that the destination MAC address carried in the broadcast packet matches the network protocol address of the second virtual machine, the second virtual machine sends a unicast response packet to the second node.
In step S406, the second node forwards the unicast reply message to the third node.
In some embodiments, the second node stores the corresponding relationship between the third virtual machine and the BA interface in the second bridge, and sends the unicast reply message Wen Zhuaifa to the third node through the BA interface.
In step S407, the third node forwards the unicast reply message to the third virtual machine.
In this embodiment of the present application, after step S403, after the first virtual machine receives the broadcast message, the first virtual machine parses the broadcast message, determines that the destination MAC address carried in the broadcast message is not matched with the network protocol address of the first virtual machine, and then the first virtual machine ignores the broadcast message.
In the embodiment of the application, the message is directly received or sent among the nodes in the ad hoc network, and the message is not forwarded through the intermediate node, so that the efficiency of message transmission is improved. And, the nodes in the ad hoc network can be deployed in a two-layer network, and are suitable for applications using two-layer messages.
In the embodiment of the present application, when any node forwards a message or a unicast response message, the bridge corresponding to the node may forward the message or the unicast response message. The matching of the destination MAC address and the network protocol address of the virtual machine in the packet may mean that the destination MAC address is consistent with the network protocol address of the virtual machine.
