  30. Challenges with TCP • Isolated networks • Firewalls • Ports • Web browsers

  31. How to Extend This to the Web

  32. Controlling the Light Remotely Using Pub-Sub Over the Web

  33. HTML5 WebSocket: TCP for the Web • Standard Protocol (IETF): RFC-6455 • Standard API: • W3C: JavaScript • JSR 356: Java EE • Single socket, full-duplex • Low overhead: <1% of HTTP • Low latency: low milliseconds • SSL support Full duplex
