Status of Web Communication


HTTP Protocol

• Designed for document transmission

• Cumbersome, nearly real-time tricks• Polling, Long-Polling• Reverse-AJAX, Comet etc.

• Ultimately non-standardized hacks

• Remains a Request/Response mechanism


WebSockets - Technology

WebSocket Protocol

• Permanent TCP connections, bidirectional, full-duplex 4oo times less overhead ⅓ of latency

• Standardized in HTML5 by W3C and IETF protects investments

• Single TCP Port saves 50% server resources



WebSocket Protocol

• No Rules for Content Text/Binary Frames, Chunking/Compression Encryption (SSL/TLS)

• No Limits for Formats/Sub-Protocols JSON, XML, CSV, Map, Object…

• No Restrictions for Processing Responsible for Logic, Security

Compared with HTTP

jWebSocket Plug-ins (Open Source, Apache 2 Licence)

• Models: Channels, Events, JMS, MQ with STOMP, AMQP

• Interfaces: JDBC, SMTP, SMS, CGI, Scripting (JavaScript)

• Security: Quota, Captcha, Filters, Spring Auth, SSO, SSL/TLS

• Remote Procedure Calls: C2S-, S2C- and C2C-RPCs

• Sharing: Data Persistence/Synchronization and Filesharing

• Social: Chat, Twitter, Instant Messaging (XMPP)

• Administration: JMX, Logging, Statistics, Monitoring, Reporting, Clustering

jWebSocket - Plug-ins



WebSocket Summary

• Designed for highly interactiveWeb Applications, high level of freedom

• Supports stationary & mobile,browser based & native apps

• Not just a protocol, but a new paradigmRequest/Response Real-Time Comm.

• Perfect Basis for Low-LatencyCommunity and Enterprise Middleware

jWebSocket - Middleware

jWebSocket Middleware

• Combining Real-Time Communicationwith Message Queuing

• Integration: Web Frameworks, Devices, Clients, Servers, Services

• Abstraction: Tokens, Plug-Ins, Apps

• Decoupling: Interfaces

• Security: Roles, Filters, Quotas, Encryption

• Acknowledge & Auto Acknowledge

• ExpirationOption Notification via Advisory-Topic

• Persistence:„Survive a Broker Restart“

• Durable Subscriptions„Survive a Endpoint Restart“
