6. 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”

7. Multi-User Application
user - user server - user
user - broadcast server - broadcast

8. Multiple clients

9. Potencial Applications
1. Complex Chat
2. Realt-time Monitoring Application

10. Protocols - HTTP - Restful
● Simple
● All clients support
● Mature - Developer Experience
● Many server - framework - libraries
options
● Ajax
● Scalability
PROS

11. 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

12. Protocols - Socket - Websocket
● Permanent connection
● Full duplex - bidirectional
● New Websocket
● Low latency
● Overhead Reduction
● Dramatically Header Reduction
PROS

13. Protocols - Socket - Websocket
● Scalability
● Less server - frameworks - libraries
options
● Session management - session is evil
● Reconnection management
● Developer experience
● Complex
Cons

14. Server - Client Communication
vs

15. Client - Client Communication
?
