What is Real-Time?

● Web: 1 httpRequest - ~300 - 500 ms● System Monitoring: ~1 - 5 segs● Messaging Application: ~ 500ms - 20 segs● Collaborative Application: 1 Message - ~50 - 100 ms - FULL DUPLEX● Chat Application: 1 Message - ~50 - 100 ms - FULL DUPLEX● Multiplayer games : 1- 2 Frames - ~ 40ms - FULL DUPLEX

“Time is relative”

Multi-User Application

user - user server - user

user - broadcast server - broadcast

Multiple clients

Potencial Applications

1. Complex Chat2. Realt-time Monitoring Application3. Collaborative Application - Whiteboard, Shared

docs…4. Industrial Control System5. Data Acquisition Server6. Multiplayer Games

Protocols - HTTP - Restful

● Simple● All clients support● Mature - Developer Experience● Many server - framework - libraries

options● Ajax● Scalability

PROS

Protocols - HTTP - Restful

● No persistent connection● No server to client messages● Http - Header size● Pull based application - one direction● Latency● New connection per request

CONS

Protocols - Socket - Websocket

● Permanent connection● Full duplex - bidirectional● New Websocket ● Low latency● Overhead Reduction● Dramatically Header Reduction

PROS

Protocols - Socket - Websocket

● Scalability● Less server - frameworks - libraries

options● Session management - session is evil● Reconnection management● Developer experience● Complex

Cons

Server - Client Communication

vs

Client - Client Communication

?

Client - Client Communication

So...Which Protocol?

Socket - Websocket

Let´s Start !!!
