Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The network communication method, apparatus, electronic device and storage medium provided by the present invention are described below with reference to fig. 1 to 13.
The invention provides a network communication method, which is suitable for a dual-redundancy backup network system, wherein the dual-redundancy backup network system comprises at least two groups of switch sets and a plurality of network nodes, each group of switch sets comprises two switches which are mutually backed up, and each switch is provided with a routing strategy. In the system, a hot backup mode and a warm backup mode can be adopted for data transmission. For this reason, the routing policy is also correspondingly divided into a hot backup routing policy and a warm backup routing policy.
In the invention, each data transmission process is completed by interaction between two groups of exchange sets which are in communication relation with each other. For this purpose, the switches in the two groups of switch groups establishing the communication relationship establish a routing topology with the source node and the destination node.
In the present invention, one network node (source node) transmits data to another network node (destination node) through two switch groups in communication with each other.
Fig. 1 shows a flow diagram of a network communication method provided by the present invention, and referring to fig. 1, the method includes:
11. the current switch acquires data to be transmitted and determines the data type of the data to be transmitted; the data types comprise a hot backup data type and a warm backup data type;
12. the current switch determines a corresponding routing strategy according to the data type;
13. the current switch acquires the state of each link on the routing topology, and a new routing topology is obtained according to the routing strategy and the state of each link;
14. and the current switch sends the data to be transmitted to the next switch or the destination node according to the new routing topology.
With respect to the above steps 11 to 14, it should be noted that, in the present invention, two groups of switch groups are in communication with each other, a source node (i.e. a party sending data) establishes a link with a switch in one of the switch groups, and a destination node (i.e. a party receiving data) establishes a link with a switch in the other switch group.
The method is suitable for the communication process of the source node and the destination node in the two groups of exchange sets establishing the communication relationship. The current switch mentioned in the above steps is the switch to be subjected to the data forwarding action in the two groups of switch groups.
In the invention, after the current switch acquires the data to be transmitted, the next switch for executing data forwarding or the destination node needs to be determined so as to forward the data to be transmitted to the next switch or the destination node.
In the present invention, as shown in fig. 2, the network nodes in the dual redundant backup network system include FC nodes and ethernet nodes. The FC node belongs to an FC network, and the FC network is a new high-speed network which is parallel to the traditional TCP/IP network. The FC nodes communicate with each other through an FC-AE-1553 protocol and an IPFC protocol. An ethernet node belongs to the ethernet, which is a kind of local area network. The Ethernet nodes communicate with each other through an Ethernet protocol.
The FC node and the ethernet node may also communicate with each other using the IPFC protocol and the ethernet protocol, but require a switch for protocol conversion.
Therefore, in the invention, the communication protocols adopted by the FC node and the Ethernet node are uniformly converted into a preset frame format (such as FC frame format) in the switch for data exchange.
In the invention, the FC-AE-1553 protocol adopts a hot backup communication mode, two channels simultaneously transmit data, and redundancy removal processing is carried out during receiving. The IPFC protocol and the Ethernet protocol adopt a warm backup mode, one channel is adopted by default to carry out data sending and receiving processing, and if the default communication channel fails, the other channel is automatically switched to carry out data sending and receiving.
Therefore, the data types of the data to be transmitted include a hot backup data type and a warm backup data type.
In the present invention, a hot backup routing policy (i.e. a static routing policy) is adopted for data of a hot backup data type, and the hot backup routing policy includes: and if the fault link exists according to the state of each link, keeping the initial routing topology unchanged. That is, the switch does not update the initially configured routing topology according to network failure or the like.
And adopting a warm backup routing strategy (namely a dynamic routing strategy) aiming at the data of the warm backup data type. The warm backup routing strategy comprises the following steps: and if the fault link exists according to the state of each link, updating the initial routing topology according to the fault link. That is, the switch recalculates the routing topology according to the network failure, and notifies the switches cascaded with the switch to ensure that all switches in the network can complete the routing topology updating.
Therefore, in the invention, the current switch determines the corresponding routing strategy according to the data type. And simultaneously acquiring the states of all links on the routing topology in real time. The link state comprises the connection and disconnection of a link between the node and the switch and the connection and disconnection of a link between the switch and the switch.
Then, the current switch obtains a new routing topology according to the routing strategy and the states of all the links. Here, for the hot-standby routing policy, since the original routing topology is not changed, for this reason, the new routing topology is still the original routing topology. For the warm backup routing strategy, the new routing topology is the updated routing topology due to the change of the initial routing topology.
And then, the current switch sends the data to be transmitted to the next switch or a destination node according to the new routing topology.
In the invention, aiming at the routing topology of the warm backup, when all switches, nodes and link communication in a network are normal, the link communication can be established among default switches, but the initial routing topology does not transmit data through the switches in the same switch group for the time.
For a hot-standby routing topology, switches in the same switch group do not establish link communication in the network.
In the communication network, the data transmission adopts the modes of unicast, multicast and broadcast data forwarding.
The unicast data forwarding mode is a one-to-one communication mode, and the switch in the network only forwards data and does not copy the data.
The multicast data forwarding mode is a one-to-one communication mode.
The broadcast data forwarding mode is a one-to-many communication mode.
Therefore, in the invention, no matter in a unicast, multicast or broadcast data forwarding mode, each data transmission process is completed by two groups of switch groups establishing a communication relationship. Each data transmission process is performed according to the above steps.
According to the network communication method provided by the invention, the corresponding routing strategy is determined according to the data type, the new routing topology is obtained according to the routing strategy and each link state on the basis of each link state on the routing topology, the data forwarding process is completed according to the new routing topology, the consideration from multiple backup data types is realized, the compatible processing of multiple backup forwarding modes is realized in one network, and the adaptability of data transmission is improved.
In the further explanation of the network communication method, the processing procedure for determining the data type of the data to be transmitted is mainly explained as follows:
in the invention, the data sent by the source node is forwarded through the exchanger in one exchanger group, then through the exchanger in another exchanger group, and finally forwarded to the destination node. To this end, different switches differ in the way data is processed.
If the current switch is the first switch connected with the source node, determining the data type of the data to be transmitted, specifically:
the method comprises the steps that a current switch receives original data sent by a source node, and the original data are converted according to a preset frame format to obtain data to be transmitted;
determining the protocol type of the original data, and determining the data type of the data to be transmitted according to the protocol type.
In this regard, it should be noted that, based on the above description of the communication protocols of different network nodes, in the present invention, the FC-AE-1553 protocol adopts a hot backup communication mode. The IPFC protocol and the Ethernet protocol adopt a warm backup mode.
For this purpose, a first switch connected to the source node receives raw data transmitted from the source node, the raw data being data related to the own communication protocol of the own node. The switch converts the original data according to a preset frame format to obtain the data to be transmitted, thereby facilitating the subsequent data forwarding. Meanwhile, the data type of the data to be transmitted can be determined according to the protocol type.
If the current switch is an intermediate switch or a first switch connected with the destination node, determining the data type of the data to be transmitted, specifically:
acquiring a preset field of data to be transmitted, and determining a numerical value on the preset field;
and determining the data type of the data to be transmitted according to the numerical value on the preset field.
In this regard, it should be noted that, since the intermediate switch or the first switch connected to the destination node receives the data converted by the first switch connected to the source node. The data does not have the communication protocol of the original data. However, the first switch connected to the source node will configure a value capable of distinguishing the data type in a predetermined field of the data during the conversion process. For this reason, the other switches need to determine the data type of the data to be transmitted according to the value in the preset field.
For example, due to the difference of communication paths used by the hot backup and the warm backup in communication, when data is transmitted, the hot backup data and the warm backup data are defined by distinguishing according to the reserved bit of the F _ CTL field of the FC frame, the F _ CTL field has 24 bits in total, the F _ CTL field is distinguished by using the reserved bit10 in a backup manner, when bit10 is 0, the hot backup data is represented, and when bit10 is 1, the warm backup data is represented.
In the further explanation of the network communication method, the process of obtaining the link states on the routing topology and obtaining a new routing topology according to the routing policy and the link states is mainly explained as follows:
and when the fault link is determined to exist according to the state of each link, keeping the original routing topology unchanged. And sending the data to be transmitted to the next switch or the destination node according to the initial routing topology.
And when the fault link exists according to the state of each link, updating the initial routing topology according to the fault link to obtain a new routing topology. And sending the data to be transmitted to the next switch or the destination node according to the new routing topology.
In the further method of the method, based on each link state on the routing topology, the new routing topology is obtained according to the routing strategy and each link state, the data forwarding process is completed according to the new routing topology, the consideration of multiple backup data types is realized, the compatible processing of multiple backup forwarding modes is realized in one network, and the adaptability of data transmission is improved.
The following explains the unicast, multicast and broadcast data forwarding modes of the data in the network by adopting the warm backup mode and the hot backup mode respectively:
the warm backup unicast communication selects the communication between the ethernet node 1 and the ethernet node 2 in the network as an example to explain the implementation scheme.
When the network devices (switches and nodes) and link communication are normal, the ethernet node 1 and the ethernet node 2 both perform ethernet communication through the a route, data forwarding is performed between the switches according to a default route, data transmission is not performed between the switch 21 and the switch 22 according to a default route topology, and a communication link between the ethernet node 1 and the ethernet node 2 is 1- >2- >3, as shown in fig. 3.
When the link 1 fails, the ethernet node 1 switches to use the B-path for communication, the routing topology of the switch updates the routing topology according to the link connection state, and the communication link between the ethernet node 1 and the ethernet node 2 is 4- >7- >2- >3, as shown in fig. 4.
When the link 3 fails, the ethernet node 2 switches to use the B route for communication, the switch routing topology updates the routing topology according to the link connection state, and the communication link between the ethernet node 1 and the ethernet node 2 is 1- >7- >5- >6, as shown in fig. 5.
When the link 2 fails, each switch reestablishes a generated routing topology, establishes a communication connection between the switch 21 and the switch 22, and the communication links between the ethernet node 1 and the ethernet node 2 are 1- >7- >5- >8- >3, as shown in fig. 6.
When both the link 1 and the link 2 fail, the ethernet node 1 switches to use the B path for communication, each switch reestablishes the spanning tree topology, establishes a communication connection between the switch 21 and the switch 22, and the communication link between the ethernet node 1 and the ethernet node 2 is 4- >5- >8- >3, as shown in fig. 7.
When both the link 1 and the link 3 fail, both the ethernet node 1 and the ethernet node 2 switch to use the B-path for communication, and the communication link between the ethernet node 1 and the ethernet node 2 is 4- >5- >6, as shown in fig. 8.
The preparation work of each device in the warm backup multicast communication scheme is as follows:
1) an Ethernet node:
the Ethernet node sends out corresponding IGMP protocol message when joining the multicast group or quitting the multicast group; after the Ethernet node joins the multicast group, the multicast data can be transmitted and received.
2) FC node:
when the FC node is used for IPFC protocol communication, corresponding IGMP protocol messages are sent out when the FC node is added to a multicast group or quits the multicast group, and the IGMP protocol messages are packaged according to the IPFC protocol; after the FC node joins the multicast group, the transmitting and receiving of the IPFC protocol multicast data can be carried out.
3) The switch will forward the multicast data packet according to the self-maintained multicast routing table;
the exchanger carries out protocol conversion according to IGMP protocol messages sent by the Ethernet nodes, and packages and sends the messages to the exchange module according to an IPFC protocol;
the switch directly receives an IGMP protocol message encapsulated by an IPFC protocol sent by an FC node;
after receiving an IGMP protocol message encapsulated by an IPFC protocol, the switch updates a maintained multicast data forwarding table;
one switch between the switches in the network takes the role of the multicast router to realize the convergence and management work of the multicast routing information of the whole network; when the multicast routing of other switches changes, the multicast router is informed, and the multicast router also synchronizes the multicast routing information to other switches in the network;
when the switch which takes the role of the multicast router is down, the multicast router is reselected according to the network protocol.
The warm backup broadcast communication scheme is as follows:
the physical looped network is converted into the routing topology of the logical topology tree through the Spanning Tree Protocol (STP) between the switches, and further the broadcast storm is avoided.
As shown in fig. 3, in the case where the links are all connected normally, there is a communication loop of 2- >8- >5- > 7; the switch can realize the shielding function of part of the links by using the spanning tree protocol, and shields the number 8 switching link by using the switch 11 as a root node, and the generated topology tree is shown in fig. 9.
When the ethernet node 1 transmits broadcast through the link No. 1, the switch 11 will forward the data inside the switch according to the forwarding table generated by the topology tree, and forward the data to the switch 12 and the switch 21 through the cascade interface. The broadcast data received by the switch 12 will be forwarded to the switch 22, the broadcast data received by the switch 21 will not be forwarded to the switch 22, and the broadcast data received by the switch 22 will not be forwarded to the switch 21.
When the link 2 fails, the topology tree between the switch 11 and the switch 21 disappears, and the spanning tree protocol is updated, and the updated topology tree is shown in fig. 10.
The hot backup unicast communication selects FC node 1 and FC node 2 in the network as an example to implement hot backup scheme description, and the routing topology is shown in fig. 11.
According to the routing topology, the link 7 and the link 8 do not perform any data forwarding, and the two links in the network can be considered to be absent in the hot backup communication. The communication links of FC node 1 and FC node 2 are two, 1- >2- >3 and 4- >5- >6 respectively, so that the communication between FC node 1 and FC node 2 is not affected by the disconnection of either link alone in the network.
When two or three of link 1, link 2, and link 3 in the network are broken, communication between the two nodes is not affected because there is a 4- >5- >6 transmission link between FC node 1 and FC node 2.
When two or three of links 4, 5, and 6 in the network are broken, communication between the two nodes is not affected because there is a 1- >2- >3 transmission link between FC node 1 and FC node 2.
In addition, the FC node hot backup multicast or broadcast communication carries out table lookup and forwarding processing in the switch according to the routing topology according to the multicast ID.
