are consistent. In order to solve this distributed consistency problem, predecessors summed up many typical protocols and algorithms during the repeated trade-offs between performance and data consistency. Among the more notable are the second-order commit protocol (two Phase commitment Protocol), the Sankai commit protocol (three Phase commitment

Tags: col transmission broadcast tip Local computer network Tran technology familySingle shared broadcast channel, if two or more than two nodes simultaneously transmit, will interfere with each other (interference) conflict (collision): Nodes receive two or more signals at the same time → Receive failed! The MAC protocol uses a distributed algorithm to determine how nodes share channels, that is, when decision nodes can transmit data. It must be base

Brief introductionHypertext Transfer Protocol (hypertext Transfer Protocol, referred to as HTTP) is the application layer protocol. HTTP is a request/response protocol that sends a request to the server after a client has established a connection with the server, and responds to the request after the server has receive

1. Protocol Buffers Introduction　Protocol Buffers (PROTOCOLBUFFER/PROTOBUF) is a data-description language developed by Google, similar to the ability of XML to serialize structured data that can be used to persist data or serialize data to be transmitted over a network. Mainly used in data storage, communication protocols and so on. This stage supports 6 programming languages such as C + +, JAVA, Python, O

HTTP protocol Summary HTTP protocol (Hyper-Text Transfer Protocol) HTTP is a stateless, application-level protocol based on the request-response model, which is based on a TCP link (three handshake) and an ongoing link mechanism in the HTTP 1.1 version, most of which are built on the HTTP

HTTP is a stateless protocol, with two consecutive requests for the same session that are not known to each other, and they are parsed by the newly instantiated environment, which does not save any information about the session, except that the application itself may already be stored in the global object. Own understanding, In asp: Every time the page is committed, the next commit will not be remembered, except that the application itself may have be

Application layer protocol: Each application tier is designed to solve a class of application problems. The solution of the problem must be accomplished through communication and collaboration between multiple application processes located in different hosts. Strict rules must be observed between application processes. Application-layer protocols should be defined as follows: the types of messages exchanged between application processes, such as the i

TCP/IP protocol ----- excellent notes, tcpip protocol -----1. Introduction The TCP/IP Protocol is not a single TCP Protocol or an IP Protocol. It is a group of protocols, including TCP and IP Protocol, UDP

Protocol protocol:The protocol is similar to the interface in C #L used to declare the methodL if a class complies with an agreement, then it has all the statements of the agreement.L can comply with multiple protocolsAs long as the parent adheres to a protocol, the subclass adheres to that protocol.Comply with the agreement Inheritance by:1.

, it becomes easy to enable the GTIDs function. However, GTIDs not only replaces the old binary log file/location with a separate identifier, but also adopts a new replication protocol. If you do not understand this yet, you can learn something in this article. Replication protocol: New VS old The old protocol is often simple: first, connect to a given binary log

MySQL5.6 has many new features, many of whom are interested in the global transaction ordinal function (Gtids). The reason why everyone is interested in this feature is that it's always a hassle to reconnect from the server and a new primary server, but it's easy to do after enabling the Gtids feature. However, the use of Gtids not only replaces the old binary log file/location with a separate identifier, it also uses a new replication protocol. If yo

First, Introduction The Protocol deals with properties and methods that act like abstract classes in Java, and types in swift implement some of the agreed properties and methods by adhering to the protocol. The protocol in Swift is declared using the Protocol keyword. The protocol
