RSocket
RSocket is an application protocol initially developed bNetflix that supports Reactive Streams. The motivation behind its development was to replace hypertext transfer protocol (HTTP), which is inefficient for many tasks such as microservices communication, with a protocol that has less overhead. Protocol RSocket is a binary protocol for use on byte stream transports such as TCP, WebSockets, and Aeron Aeron is used in several ways including: People ;Given name *Aeron Clement (1936–1989), American science fiction author ;Fictional characters *Aeron Azzameen, only daughter of the Azzameen family from the video game, '' Star Wars: X-Wing Allia .... It enables the following symmetric interaction models via async message passing over a single connection: * request/response (stream of 1) * request/stream (finite stream of many) * fire-and-forget (no response) * channel (bi-directional streams) It supports session resumption, to allow resuming long-lived streams across differen ...

Reactive Programming
In computing, reactive programming is a declarative programming paradigm concerned with data streams and the propagation of change. With this paradigm, it's possible to express static (e.g., arrays) or dynamic (e.g., event emitters) data streams with ease, and also communicate that an inferred dependency within the associated execution model exists, which facilitates the automatic propagation of the changed data flow. For example, in an ''imperative'' programming setting, a := b + c would mean that a is being assigned the result of b + c in the instant the expression is evaluated, and later, the values of b and c can be changed with no effect on the value of a. On the other hand, in ''reactive'' programming, the value of a is automatically updated whenever the values of b or c change, without the program having to explicitly re-execute the statement a := b + c to determine the presently assigned value of a. Another example is a hardware description language such as Verilog, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Network Programming
Computer network programming involves writing computer programs that enable processes to communicate with each other across a computer network. Connection-oriented and connectionless communications Very generally, most of communications can be divided into connection-oriented, and connectionless. Whether a communication is connection-oriented or connectionless, is defined by the communication protocol, and not by . Examples of the connection-oriented protocols include and , and examples of connectionless protocols include , "raw IP", and . Clients and servers For connection-oriented communications, communication parties usually have different roles. One party is usually waiting for incoming connections; this party is usually referred to as "server". Another party is the one which initiates connection; this party is usually referred to as "client". For connectionless communications, one party ("server") is usually waiting for an incoming packet, and another party ("cli ...

Reactive Streams
Reactive Streams is an initiative to provide a standard for asynchronous stream processing with non-blocking back pressure. __TOC__ Origin Reactive Streams started as an initiative in late 2013 between engineers at Netflix, Pivotal and Lightbend. Some of the earliest discussions began in 2013 between the Play and Akka teams at Lightbend. Lightbend is one of the main contributors of Reactive Streams. Other contributors include Red Hat, Oracle, Twitter and spray.io. Goals The main goal of Reactive Streams is to govern the exchange of stream data across an asynchronous boundary like passing elements on to another thread or thread-pool while ensuring that the receiving side is not forced to buffer arbitrary amounts of data. In other words, back pressure is an integral part of this model in order to allow the queues which mediate between threads to be bounded. The intention of the specification is to allow the creation of many conforming implementations, which by virtue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HTTP
The Hypertext Transfer Protocol (HTTP) is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access, for example by a mouse click or by tapping the screen in a web browser. Development of HTTP was initiated by Tim Berners-Lee at CERN in 1989 and summarized in a simple document describing the behavior of a client and a server using the first HTTP protocol version that was named 0.9. That first version of HTTP protocol soon evolved into a more elaborated version that was the first draft toward a far future version 1.0. Development of early HTTP Requests for Comments (RFCs) started a few years later and it was a coordinated effort by the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C), with work later moving to ...

Microservices
A microservice architecture – a variant of the service-oriented architecture structural style – is an architectural pattern that arranges an application as a collection of loosely-coupled, fine-grained services, communicating through lightweight protocols. One of its goals is that teams can develop and deploy their services independently of others. This is achieved by the reduction of several dependencies in the code base, allowing for developers to evolve their services with limited restrictions from users, and for additional complexity to be hidden from users. As a consequence, organizations are able to develop software with fast growth and size, as well as use off-the-shelf services more easily. Communication requirements are reduced. These benefits come at a cost to maintaining the decoupling. Interfaces need to be designed carefully and treated as a public API. One technique that is used is having multiple interfaces on the same service, or multiple versions of the sam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WebSocket
WebSocket is a computer communications protocol, providing full-duplex communication channels over a single TCP connection. The WebSocket protocol was standardized by the IETF as in 2011. The current API specification allowing web applications to use this protocol is known as ''WebSockets''. It is a living standard maintained by the WHATWG and a successor to ''The WebSocket API'' from the W3C. WebSocket is distinct from HTTP. Both protocols are located at layer 7 in the OSI model and depend on TCP at layer 4. Although they are different, states that WebSocket "is designed to work over HTTP ports 443 and 80 as well as to support HTTP proxies and intermediaries", thus making it compatible with HTTP. To achieve compatibility, the WebSocket handshake uses the HTTP Upgrade header to change from the HTTP protocol to the WebSocket protocol. The WebSocket protocol enables interaction between a web browser (or other client application) and a web server with lower overhead th ...

Network Socket
A network socket is a software structure within a network node of a computer network that serves as an endpoint for sending and receiving data across the network. The structure and properties of a socket are defined by an application programming interface (API) for the networking architecture. Sockets are created only during the lifetime of a process of an application running in the node. Because of the standardization of the TCP/IP protocols in the development of the Internet, the term ''network socket'' is most commonly used in the context of the Internet protocol suite, and is therefore often also referred to as Internet socket. In this context, a socket is externally identified to other hosts by its socket address, which is the triad of transport protocol, IP address, and port number. The term ''socket'' is also used for the software endpoint of node-internal inter-process communication (IPC), which often uses the same API as a network socket. Use The use of the term ''socke ...
