Paxos is an algorithm that can reliably and consistently achieve consensus consistency based on a large set of completely unreliable network conditions. That is, it allows a group of not-so-reliable processors (servers) to agree on a secure consensus if certain conditions are met, and to ensure that the set of processors (servers) are consistent if conditions are not met. what is consensus.
Specifically: in distributed systems due to communication between networks may be interrupted, although t
first reached valueFirst, specify that each acceptor must approve the first arriving value. Which value reaches most approvals is the final approved valueBut there is a problem, for example, because no value is approved by the majority, and a final value cannot be approved. This requires acceptor to approve a value and then approve the different values according to a certain rule.back to topApprove the value of each proposalThe next step is to acceptor approve each proposed value, but this also
recovery mode is over. State synchronization ensures that the leader and server have the same system state.• To ensure transactional order consistency, zookeeper uses an incremental transaction ID number (ZXID) to identify transactions. All the proposals (Proposal) were added to the ZXID when they were presented. The implementation in ZXID is a 64-bit number, and its high 32 bits are the epoch used to identifyLeader relationship changes, each time a
derived from the front and back events. A recently published paper attempts to describe events in video through multiple statements, but the paper uses "cooking" instructional video, which has a high correlation between events and objects, and has a certain sequence of occurrences.
The authors prove that their model does not apply to "open" Time-domain ("open" domain) video, where events occur as behavior-driven and different events may overlap. The author proposes a description module, which
wrapping the write operation as a transaction execution, follower participate in the execution of the writing process of voting, Observer, however, receives only the last inform message and does not participate in the updated voting process.When follower receives a write request, follower transfers it to Leader,leader to encapsulate it as a transaction and process, each transaction contains a Zxid,zxid divided into two parts, epoch and counter. Epoch is used to identify the current leader, a ne

How a programmer can earn pocket money with graceThe ideal list is to go directly to overseas projects, such as freelance.com and other websites.Domestic shixian.com Price is also very good, there is a software crowdsourcing platform CODING code City will review all the projects to ensure the clarity of the project requirements, and provide payment guarantee, so that developers can only complete the project development on time to obtain remuneration. You can see the developer's comment on the co

Have the opportunity to group a small team, find a few peers good friends, components of a team, you can contact reverse telecommuting. Even if there is no reverse telecommuting, we can talk about doing something new. As a s

algorithm determines a resolution by two stages:
PHASE1: Determine who has the highest number, only the highest number of people have the right to submit proposal (proposal: Given the specific value);
Phase2: The highest-numbered submitted proposal, if no other node proposed a higher number of proposal, then

In this example, Peer n subscribes to all channels and we see that each channel has a related ledger. In other words, in a block chain network, each node can have multiple ledger.

duplicated, may be lost, but they will not be corrupted
2.2 Choosing a ValueThe existence of a single acceptor agent is the simplest way to choose value. Proposer sent a proposal to acceptor, which received the first one received. Although it is very simple, this method is not sufficient because of the acceptor failure, because the failure of the acceptor will result in the subsequent operation is not possible.So we need to try another way of ch

zookeeper
The core of zookeeper is atomic 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 ensur
Girshick, Ross. "Fast r-cnn."

The source code is available on GitHub.The reason why fast r-cnn is proposed is mainly because R-CNN has the following problems:
