The nodes of the whole network adopt the same network protocol for network connection, if the nodes are assumed to be TCP protocol, other nodes must be TCP, and if the nodes want to adopt other protocol UDP, the nodes can be directly rejected by the nodes of the other party. However, the TCP protocol must establish a connection, perform error check, and ensure that the files are received according to the sending sequence, which also makes the transmission efficiency and speed of the TCP protocol not superior. The UDP protocol is well known for simplicity and high efficiency, but the reliability and accuracy of transmission are greatly compromised, and there are various transmission requirements in the blockchain network, and it is obvious that all the transmission requirements cannot be met by only using one network transmission protocol.

For a further understanding of the present invention, reference will now be made in detail to the embodiments illustrated in the drawings.
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
The terms first, second, and the like in the present invention are provided for convenience of describing the technical solution of the present invention, and have no specific limiting effect, but are all generic terms, and do not limit the technical solution of the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Example 1
As shown in fig. 1, a multi-protocol connection method for a blockchain network, where the blockchain network includes a first node and a second node responding to a connection request of the first node, and multiple transport protocols are configured in the first node, includes:
s100, the first node constructs an address information set according to a plurality of transmission protocols. The address information set comprises a plurality of address information, and the plurality of address information correspond to a plurality of transmission protocols configured by the address information set.
S200, the first node accesses the block chain network through a built-in guide node. The method comprises the following specific steps:
s201, the first node acquires the address information of the guide node.
S202, the first node calls a corresponding transmission protocol according to the address information of the guide node and establishes connection with the guide node.
S203, the first node sends the address information set to the guide node.
S300, the first node acquires the address information of the second node. Wherein the address information comprises a mark field and a protocol address, and the mark field is used for marking the type of the transmission protocol applicable to the second node.
S400, the first node calls a corresponding transmission protocol according to the address information of the second node and establishes connection with the second node. Preferably, after the first node accesses the blockchain network, the first node is disconnected from the bootstrap node after forming stable connections with the N nodes.
S500, the first node broadcasts the address information set of the first node to the nodes connected with the first node. Preferably, the address information in the address information set is provided with a priority order.
In the above scheme, the first node constructs its own address information set after starting, the address information in the address information set corresponds to its configured network transmission protocol one by one, and configures one address information for each protocol, and the address information used here includes an IP address and a tag field, and the tag field is added before the IP address for tagging the protocol type, so the IP addresses of the address information in the address information set are all the same, but the protocol types in the tag field are all the same and correspond to the network transmission protocol configured by the first node one by one. After the first node is started, the first node accesses the blockchain network through a built-in guide node, the first node sends an address information set of the first node to the guide node, other nodes in the blockchain network can acquire the address information of the first node through the guide node so as to establish connection with the first node, the first node can also actively establish connection with other nodes, and after the first node is connected with enough nodes, the first node can be disconnected with the guide node so as to guide resources of the nodes. The address information in the address information set is prioritized according to settings, for example, when the contents such as video transmission and the like are mainly used among nodes, the priority of the UDP protocol can be set up to be adjusted up, so that the transmission among the nodes is more consistent with the application scene, the system overhead of network connection is reduced, and the overall performance of the block chain is improved.
Specifically, taking the node a configured with the TCP protocol and the UDP protocol as an example, the node a constructs a network address of the blockchain network where the node a is located according to the network protocol configured by the node a, for example, if the TCP protocol is selected, the network address of the node is: /tcp/122.224.166.11: 13802/pid; if the UDP protocol is selected, its network address: (viii)/udp/122.224.166.11: 13802/pid; the address information set of node a includes two address information corresponding to the TCP protocol and the UDP protocol, respectively: d {/tcp/122.224.166.11: 13802/pid; /udp/122.224.166.11:13802/pid }
Where D is the set of address information.
The two pieces of address information may be prioritized according to information such as the protocol usage of the entire network or the protocol of the pre-connection node.
After the A node is started, network connection is carried out according to a built-in guide node or a configured seed node, if the built-in guide node is/tcp/ip: Port/pid, the node starts to initiate network connection to the ip and the Port where the pid node is located by using tcp, and if the address format of the guide node or the configured seed node is as follows: port/pid, udp is enabled to initiate network connection. After the connection of the node A is stable, the node A is disconnected with the guide node or the seed node, so that the resource of the guide node or the seed node is saved, and the guide node or the seed node store can serve more nodes. After the connection is stable, the node A broadcasts the network address of the node A to other nodes connected with the node A, and the other nodes can store the network address for other nodes in the network to search for the network.
As shown in fig. 2, node a and node B transmit through UDP, node B and node D transmit through TCP, node D and node C transmit through UDP, and node C and node a are both compatible with UDP and TCP, a network transmission protocol can be selected according to requirements, a blockchain network shown in fig. 2 can be compatible with multiple network transmission protocols, nodes can freely select which communication protocol to use for communication according to their usage scenarios, if their requirements are higher TPS, a large number of transactions are broadcast in a short time, a UDP protocol can be selected, which protocol has the advantage of reducing the overhead of network connection, or it is only a node that is deployed, without service sensitivity, or it can be selected. UDP has many advantages that TCP does not have, UDP does not have flow control, it can be spread quickly, it is very helpful for low-latency applications, such as making a decentralized voice communication, UDP can be selected to be widely used in audio and video transmission.
The scheme provided by the embodiment diversifies network connection modes between nodes, is not limited to a single network protocol, freely switches network protocol modes required by the nodes according to respective service scenes, can well perform compatibility on other nodes of the network, can freely select whether to support a TCP (transmission control protocol) or UDP (user datagram protocol) protocol or both the TCP and UDP (user datagram protocol) protocols when a new chain is deployed, and has higher freedom in selecting the protocols.
