After the business-to-business, c2c and after, Ma Yun found a new way to do E-commerce--p2c (Service Provider to Consumer), simply to rent a house, book tickets, even wash feet, eat these life "chores" are moved to the Internet to spend. 　　E-commerce of service industry Last week, Alibaba Group, China's Yahoo and Word-of-mouth Network announced the merger, and officially launched the "Yahoo Life Service new platform of Word-of-mouth."

Peer-to-peer, P2C, O2O, Business-to-consumer, business-to-business, c2c, see these dazzling flooded the internet is not the word, is not very familiar. However, there is no egg to be familiar with, if you do not understand the meaning of them, do not understand their differences, you take what the show force lattice it. Don't worry, come here, there is a picture, read it will refresh your business style, open career pattern, open a new chapter of lif

consistent with the previous one, that is, when a value is selected in fact, the subsequent proposer cannot submit different values to disrupt the previous results. This is a general description, but if this description can be implemented, the paxos algorithm can be ensured. Therefore, P2 is also called "safety property ". The subsequent discussions are based on "if a proposal with value V is chosen", how to ensure that "then every higher-numbered proposal that is chosen has value v ", How to i

detailed steps, Lamport is through the gradual enhancement of the way to implement P2, mainly from the following aspects: Request for the entire result (P2) Request for acceptor (P2A) Request for Proposer (P2B) Simultaneous request for acceptor and proposer (P2C) It is unclear why Lamport can divide the process so clearly, but from the articles published by Lamport, he has a deep knowledge of the distribution, and for a long

behavior of proposer:P2B: Once a proposal with value V is approved (chosen), then any subsequent proposal by proposer must have value v.Since Acceptor can accept the proposal must be proposed by proposer, so p2b implication P2A, is a stronger constraint.But according to P2B difficult to put forward the means of implementation. It is therefore necessary to further strengthen the P2B.Suppose that a value V with number M has been approved (chosen) to see under what circumstances any proposal with

(chosen), and we are more concerned about what the proposed proposer should do before it is determined:p2c. For the proposal (N,V), acceptor in majority s, if there is acceptor most recent (that is, the maximum ID value) accepted by the proposed value of v', then v = v'is required; otherwise v can be any valuesatisfies the p2c namely satisfies p2b (p2c = p2b = P2A = P2).The description of

hypothetical case, then we can meet the P2. Lamport's idea is that if we want to satisfy a certain condition, we can see how this condition can be satisfied.Assuming (M,V) has been passed, note that the majority has accepted the offer. Then there is a new offer (N,v_n), here n>m, then we need to prove v_n = v. If this is to be proved, what conditions do we need? If we use mathematical induction, then we can assume the offer of M. (n-1) The proposed leader are all V, then the idea sub-proof v_n
