are Follower, and the Leader converts the transaction requests from the client to the transaction Proposal, and distribute Proposal to all other Follower in the cluster, and then the Leader waits for the Follwer feedback. When there are more than half of the Follower feedback information (> = N/2 + 1, the Leader will broadcast the Commit information to the Follower in the cluster again, and the Commit is t

The source of research and development at the start of the project is a big deal for r \ \ u0026 research and development team, however, it is not easy to start a project, the process must meet many conditions to really start the project, otherwise, informal or even unreasonable projects will start the research and development work trapped. This paper mainly focuses on the project initiation procedure, possible problems and measures involved in the process.The scenario in this article refers to

Another protocol for implementing vpn is ipsec. To be precise, ipsec is a framework composed of multiple protocols. Its implementation can be divided into the following four steps: 1. implement data stream filtering control (control by acl) 2. Security proposal (implementing the working mode, selecting the security protocol, verifying the algorithm, and selecting the consistency of the encryption algorithm if the esp protocol is used) 3. Create a secu

validated and submittedLedger update1. Client a Initializes a transactionWhat happened. -Client A sends a request for a carrot purchase. Request target Peera and peerb who represent Clienta and CLIENTB respectively. The endorsement policy stipulates that two peer must sign any transaction, so the request is forwarded to Peera and Peerb. Next, build the trading proposal. Use an SDK (Node,java,python)-enabled application to generate trading recommendat

broadcast, which ensures synchronization between various servers. The Protocol implementing this mechanism is called the Zab protocol. The Zab protocol has two modes: recovery mode (Master selection) and broadcast mode (synchronization ). After the service is started or the leader crashes, Zab enters the recovery mode. When the leader is elected and most servers are synchronized with the leader status, the recovery mode ends. State synchronization ensures that the leader and server have the sam

Theoretical advanced-Paxos variants and optimization of distributed systemsIntroductionThe basic principles of basic Paxos and Multi Paxos are understood in the theory advanced-Paxos of distributed systems, but it is not enough to understand the fundamentals if we want to apply Paxos to engineering practice.There are many optimization based on Paxos, in order to ensure that the consistency protocol is correct (safety), reduce the Paxos resolution communication steps, avoid single point of failur

Yolo is a convolutional neural network that can predict multiple box positions and classes at once, enabling end-to-end detection and recognition of targets with the greatest advantage of being fast . In fact, the essence of target detection is regression, so a CNN that implements regression does not ne

Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. 2.4 dhcp ip Address Allocation Process 　　 The DHCP Client initializes TCP/IP and broadcasts a DHCPDISCOVER message on the local physical subnet to determine the DHCP server bit. And its IP address. If the DHCP server and the client are not in the same physical subnet, The B

recovery mode is finished. State synchronization ensures that the leader and server have the same system state. To ensure the sequential consistency of transactions, zookeeper uses an incremented transaction ID number (ZXID) to identify transactions. All the proposals (proposal) were added to the ZXID when they were presented. The implementation of ZXID is a 64-bit number, it is 32 bits high is the epoch used to identify whether the leader relationsh
