In order to explain the technical means described in the present application, the following description will be given by way of specific examples.
Referring to fig. 1, fig. 1 is a flowchart of an information transmission method based on a block chain according to an embodiment of the present application. As shown in fig. 1, an information transmission method based on a block chain includes the following steps:
The forwarding node list is used for recording node information of the information forwarding node corresponding to the information to be transmitted.
The information to be transmitted is, for example, information to be identified, information to be synchronized, and the like. The information to be transmitted needs to be broadcast or multicast transmitted from the current node to other nodes.
The node information of the information forwarding node comprises information such as a node name, a node address, and a corresponding mechanism of the node in the alliance chain.
In the embodiment of the present application, since the current node and the other nodes in the block chain are in a non-fully-connected network topology, when the information to be transmitted is broadcasted or multicasted to the other nodes, the information cannot be transmitted through a directly-connected network path, and therefore, the information needs to be forwarded to realize effective external broadcast or multicast transmission.
The information forwarding node is specifically a node which needs to forward and transmit information to be transmitted in the process of broadcasting or multicasting the information to be transmitted from the starting node to the destination node. More specifically, the information forwarding node is a node in an information forwarding path, and the information forwarding path is used for transmitting information to be transmitted to a destination node.
In a specific embodiment, after obtaining the information to be transmitted and the forwarding node list, the method further includes:
judging whether the node information of the information forwarding node is recorded in the forwarding node list;
if so, executing step 102, based on the forwarding node list, to extract a first forwarding node having a network direct connection relationship with the current node from the information forwarding nodes, and to extract a second forwarding node having a network non-direct connection relationship with the current node from the information forwarding nodes;
if not, it can be determined that the transmission of the information to be transmitted is finished.
The forwarding node list is used for recording node information of the information forwarding node corresponding to the information to be transmitted. When the node information of the information forwarding node is recorded in the forwarding node list, it is indicated that the information to be transmitted has other nodes to be transmitted besides the current node, that is, the information to be transmitted is not yet broadcast or multicast to all destination nodes. And when the node information of the information forwarding node is not recorded in the forwarding node list, it indicates that the current node is the last node for broadcasting or multicasting the information to be transmitted, and can judge that the transmission of the information to be transmitted is finished.
After the transmission of the information to be transmitted is determined to be completed, the information to be transmitted can be continuously subjected to consensus processing according to a consensus mechanism, or the information to be transmitted can be subjected to data processing according to the processing requirement of the current data processing item.
And 102, extracting a first forwarding node which has a network direct connection relation with the current node from the information forwarding nodes and extracting a second forwarding node which has a network non-direct connection relation with the current node from the information forwarding nodes based on the forwarding node list.
The current node is any node in the alliance chain with information transmission requirements. The current node is specifically a node itself which executes the information transmission method in the embodiment of the present application to realize information transmission when the node has an information transmission requirement.
And a network connection topological structure is formed among different nodes in the block chain, and each node can acquire a node having a network direct connection relation with the current node based on the network connection topological structure. And then determining a first forwarding node having a network direct connection relationship with the current node and a second forwarding node having a network non-direct connection relationship with the current node from the information forwarding nodes recorded in the forwarding node list.
The network connection relationship among the nodes is specifically a direct connection relationship or a non-direct connection relationship. The direct connection relation means that two nodes have a direct network connection relation; the non-direct connection relation means that two nodes do not have a direct network connection relation.
In a specific embodiment, based on the forwarding node list, extracting a first forwarding node having a network direct connection relationship with a current node from the information forwarding nodes, and extracting a second forwarding node having a network non-direct connection relationship with the current node from the information forwarding nodes includes:
determining a target node having a network direct connection relation with a current node;
acquiring a node intersection between the information forwarding node and the target node in the forwarding node list;
and taking the node contained in the node intersection as the first forwarding node, and determining the other nodes except the first forwarding node in the information forwarding nodes as the second forwarding nodes.
And determining a first forwarding node having a network direct connection relation with the current node from the information forwarding nodes by obtaining intersection operation between the information forwarding nodes in the forwarding node list and a target node directly connected with the current node, and determining the rest nodes in the information forwarding nodes as second forwarding nodes having a network non-direct connection relation with the current node.
The method realizes that the information forwarding nodes are divided into nodes which can directly transmit information by the current nodes and nodes which need to transmit information by the nodes in the direct network connection relation by the current nodes based on the forwarding node list.
The first information transmission instruction carries the information to be transmitted and the node information of the second forwarding node.
Specifically, the node information of the second forwarding node and the information to be transmitted may be packaged to generate a data packet, and the data packet is subjected to instruction encapsulation to obtain the first information transmission instruction.
Differently, in an optional embodiment, the generating a first information transmission instruction based on the second forwarding node and the information to be transmitted includes:
removing the node information of the first forwarding node from the forwarding node list to obtain an updated forwarding node list;
and generating a first information transmission instruction carrying the updated forwarding node list and the information to be transmitted.
In the process, the obtained forwarding node list is subjected to content updating, and only the node information of the second forwarding node having a network non-direct connection relation with the current node is left in the updated forwarding node list. And carrying the node information of the second forwarding node by carrying the updated forwarding node list in the first information transmission instruction.
In the processing process, after the current node acquires the information to be transmitted and the forwarding node list, a node in direct connection with the current node and a node in non-direct connection with the current node need to be extracted from the forwarding node list, the content of the forwarding node list is updated, the node information of a first forwarding node in the forwarding node list is removed, the information to be transmitted and the updated forwarding node list are transmitted to the first forwarding node in direct connection with the current node together through a first information transmission instruction, the first forwarding node can continue to repeat the operation process based on the forwarding node list carried by the first information transmission instruction after receiving the first information transmission instruction, the node in direct connection with the current node and the node in non-direct connection with the current node are extracted from the forwarding node list, the content of the forwarding node list is updated, the node information of the nodes in direct connection with the forwarding node list is removed, and the information to be transmitted and the updated forwarding node list are transmitted to the forwarding node in direct connection with the current node through the information transmission instruction until no information is recorded in the forwarding node list, and the information to be transmitted can be determined.
And step 104, sending the first information transmission instruction to the first forwarding node.
And when the first information transmission instruction is sent to the first forwarding node, the updated forwarding node list and the information to be transmitted are transmitted to the first forwarding node which has a network direct connection relation with the current node.
After the first forwarding node receives the first information transmission instruction, the forwarding node list which correspondingly acquires the information to be transmitted carried in the first information transmission instruction and records the node information of the second forwarding node can be obtained. Subsequently, the first forwarding node may perform information processing and outward transmission according to the processing flow from step 101 to step 104, until when a certain node detects that the node information of the information forwarding node is not recorded in the forwarding node list corresponding to the information to be transmitted, it indicates that the current node is the last node to broadcast or multicast the information to be transmitted, and may determine that the transmission of the information to be transmitted is completed.
In the steps, the information to be transmitted is transmitted to the network direct-connected node, and simultaneously, the information to be transmitted is jumped to the network direct-connected node, so that the information to be transmitted is transmitted to the network non-direct-connected node, and the deterministic delivery of the network information in the broadcasting or multicasting process is ensured to be realized in the state of the non-fully-connected network.
In an embodiment, as shown in fig. 2, the obtaining of the to-be-transmitted information and the forwarding node list includes:
Wherein, the transmission routing table may be a consensus routing table. The information of all the consensus nodes in the cluster is recorded in the consensus routing table. When the cluster is initially started, the consensus routing table is obtained by reading the configuration, then the cluster members dynamically join or quit, and the consensus routing table is also dynamically changed.
In the above implementation process, the current node is a production node of the information to be transmitted, that is, a start node of the information to be transmitted. At this time, the information to be transmitted and the forwarding node list are acquired by implementing the construction of the information to be transmitted and the determination of the destination node for transmitting the information to be transmitted outwards through the user operation in the node.
In another embodiment, as shown in fig. 3, the obtaining of the to-be-transmitted information and the forwarding node list includes:
And the information forwarding node and the target node are in a network non-direct connection relationship.
In the process, the current node is an intermediate node related in the process of sending the information to be transmitted from the starting node to each destination node.
At this time, the information to be transmitted and the forwarding node list are sent by the previous node in the network direct connection relationship with the current node. The information transmission instruction sent by the previous node is analyzed, and the information to be transmitted carried in the information transmission instruction and the information forwarding node which is not in direct connection with the previous node in the network relation are extracted to obtain a forwarding node list.
Correspondingly, when a first forwarding node having a network direct connection relationship with the current node is extracted from the information forwarding nodes, and a second forwarding node having a network non-direct connection relationship with the current node is extracted from the information forwarding nodes, the method can be implemented in a multi-node polling mode.
In particular, a transmission routing table may be set to record to which nodes the message producer needs to broadcast the information to be transmitted. In a broadcast scenario, the transmission routing table may specifically be a consensus routing table, and information of the consensus node is recorded in the table. The message producer is typically a consensus node.
And a to-be-transmitted node information list can be set, the list can update and record the nodes to which the information to be transmitted in the round is actually transmitted, and the nodes usually establish a direct network connection with the current node.
A forwarding node list may also be set, and nodes to which the information to be transmitted in this round cannot be sent may be updated and recorded in the list, and these nodes usually do not have a direct network connection with the current node and need to be forwarded by other intermediate nodes.
In each round of information transmission process, polling and updating are carried out on nodes in each list, so that a first forwarding node which has a network direct connection relation with a current node is extracted from the information forwarding nodes based on the forwarding node list, a second forwarding node which has a network non-direct connection relation with the current node is extracted from the information forwarding nodes, node information of the first forwarding node is removed from the forwarding node list, updating of the forwarding node list is achieved, the updated forwarding node list is transmitted to the first forwarding node which has the network direct connection relation with the current node, and deterministic delivery in a network message broadcasting or multicasting process under a non-full-connection network topology is achieved.
In combination with the above different embodiments, in a specific application process, the following may be performed:
the method comprises the steps that an original message, namely to-be-transmitted information, is constructed by a message production node, carries a forwarding node list, and is sent to a network module in the node for processing in an event throwing mode, after the network module receives the original message, the network module calculates an intersection according to node information in the forwarding node list and node information of which network connection is established in a block chain, the intersection is put into the to-be-transmitted node information list, and the rest node information is continuously stored in the forwarding node list;
and the local node packs the original message and the forwarding node list and sends the packed original message and the forwarding node list to the nodes in the information list of the node to be sent.
After receiving the message, the opposite end node reads the forwarding node list and the original message, and a network module in the opposite end node sends the forwarding node list and the original message to an upper layer module for processing in an event throwing mode and then prepares for message forwarding;
and the opposite end node calculates intersection according to the forwarding node list and the node information of the established network connection in the block chain, puts the intersection into the node information list to be sent, and eliminates the node information put into the node information list to be sent from the forwarding node list. If there is no intersection, the processing flow of the node ends.
And the opposite end node packs the original message and the new forwarding node list and sends the packed original message and the new forwarding node list to the nodes in the information list of the nodes to be sent.
And the corresponding opposite node continues to repeat the process until the forwarding node list in the network message received by the node is empty, and the forwarding is finished.
The application process realizes a network broadcasting method under the non-full connection topology, only the physical network of partial nodes needs to be communicated, so that the whole cluster network topology forms a connected graph, each node can possibly play the role of network information forwarding, and the deterministic delivery of network information is realized.
According to the method and the device, the first forwarding node which has a network direct connection relation with the current node is extracted from the information forwarding node and the second forwarding node which has a network non-direct connection relation with the current node is extracted from the information forwarding node by obtaining the information to be transmitted and the forwarding node list, an information transmission instruction carrying the information to be transmitted and the node information of the second forwarding node is generated, the information transmission instruction is sent to the first forwarding node, the information to be transmitted is transmitted to the network direct connection node, meanwhile, the information to be transmitted is transmitted to the network non-direct connection relation node through the jump of the network direct connection node, the transmission to the network non-direct connection relation node is achieved, and the fact that the network information is delivered assuredly in the broadcasting or multicasting process is achieved under the state of a non-full-connection network.
