The invention mainly aims to provide a fault-tolerant method of a P2P port address in a alliance chain, aiming at improving the fault-tolerant rate and stability of the alliance chain network communication process. In order to achieve the above object, the present invention provides a method for configuring an ip table in a node network configuration to implement addressing fault tolerance.
The following describes in detail the specific implementation steps of the connection method for the P2P port address in the federation chain of the present invention:
s1: in a system deployment stage, an ID of a node A is defined, the ID exists uniquely in a blockchain network and is used as a unique identifier of the node, and the unique identifier is broadcasted and stored in a global configuration file in the whole network;
s2: the node A acquires a plurality of external network IPs (IP 1, IP2 and IP 3) through deployment in different gateways;
s3: the node A is represented by key: establishing a corresponding relation between the node extranets IP1, IP2 and IP3 and the unique node identification ID in a value form, broadcasting the corresponding relation to the whole network, and storing the corresponding relation in a global network configuration file;
s4: the node A defines the priorities 0, 1 and 2 of three different IPs and broadcasts the priorities to the whole network, wherein 0 is the highest priority, 1 time and 2 times the lowest priority, and the priorities are stored in a global network configuration file;
s5: in the non-long connection state, the node B sends information to the node A, firstly tries to establish connection with the IP address with the priority of 0, and finishes the connection if the connection is successful. If the failed attempt is connected with the IP address with the priority level of 1, the connection is successfully established, if the failed attempt is connected with the IP address with the priority level of 2, the transmission is failed;
s6: and in the long connection state, the node B and the node A carry out long connection heartbeat packet verification through the IP address with the priority level of 0, and when the heartbeat packet verification fails and the IP address with the priority level of 0 is connected, the heartbeat packet still fails, the node B is further connected with the IP address with the priority level of 2. When long-connecting with the IP address with low priority, periodically trying to reconnect with the IP address with the highest priority;
in this embodiment, when a certain IP of the node a changes due to a special situation, other nodes may still perform information transmission interaction through the remaining standby IP.
In addition, the priority of the node IP in the embodiment is determined by operation and maintenance and broadcasted in the whole network;
further as a preferred embodiment, the gateway address with high bandwidth can be defined as high priority, so as to realize reasonable utilization of network resources.
In summary, the fault-tolerant connection method for the P2P port address in the federation chain provided by the present invention obtains a plurality of external network IPs by deploying the node under different gateways for a plurality of times, and stores the IPs in the network configuration of the whole network according to different priorities, so as to effectively avoid the problem of connection failure between nodes, improve the fault tolerance of data transmission between nodes, and improve the system stability and data transmission efficiency.
