Learning Layers
This project has received funding from the European
Union’s Seventh Framework Programme for research,
technological development and demonstration under
grant agreement no 318209.
 Open Source Framework for P2P Web DUIs
 WebRTC for Inter-Widget Communication (IWC)
 Direct P2P connections between browsers
 Fast event transfer between remote widgets
 Secure message exchange
 XMPP Extension Protocol for DTLS/SCTP
signaling over Jingle (XEP-0343)
 State-consistent, adaptive session migration
 Rapid development based on HTML5
 New application areas, e.g. gaming
Key Contributions
 Average latency decreased by 600% (from
around 150 ms to around 25 ms)
 User study with 16 participants confirmed
noticeable speed gain compared to server
based approach
Evaluation
 Message router on relay
 Signaling over XMPP PubSub channel

 Integrating OAuth2 / OpenID Connect
 Widget bundles for reducing initial migration time
because of static JavaScript/image resources
 Dynamic choice of relay host
 Integration with other IWC solutions
Current Web Engineering Challenges
 Many personal devices
 All Web capable
 Various input modalities
 Widgets as Web service
interfaces
