6. –Push applications send web content or other data without the need to request or download the data –Benefits of push technology: Immediacy Efficiency Reduced latency Longer battery life Shorter learning curve © 2009 Research In Motion Limited

7. Push technology Client/server push versus browser push –Browser push applications send web content to the web browser on the BlackBerry smartphone do not require a separate client application © 2009 Research In Motion Limited

8. Push technology Client/server push versus browser push –Client/server push applications send data from a server-side application to a custom client application on the BlackBerry smartphone Requires a custom client application Allows more control over type of content, processing and displaying of content © 2009 Research In Motion Limited

9. Push technology Client/server push versus browser push –BlackBerry MDS Connection Service administration controls the flow of data that is sent to the BlackBerry smartphone Flow control minimizes the amount of data sent over the wireless network Flow control sends five packets of data and waits for a response, If not immediately deliverable, content is queued until flow control timeout is reached © 2009 Research In Motion Limited

11. Browser push Pushing web content to BlackBerry smartphones –Options used in HTTP header for Browser push: Browser channel Browser channel delete Browser message Browser cache © 2009 Research In Motion Limited

12. Browser push Pushing web content to BlackBerry smartphones –Pushing content to a browser channel A Browser channel is an alternative entry point to the BlackBerry Browser Each channel must have a unique ID Each channel can have two icons © 2009 Research In Motion Limited IDidentifier

13. Browser push Pushing web content to BlackBerry smartphones –Two ways to delete a browser channel from the BlackBerry smartphone –The server-side push application can submit a browser channel delete request to delete the browser channel –The user can delete the browser channel manually –Requesting notification when a user deletes a browser channel © 2009 Research In Motion Limited

Browser push Pushing web content to BlackBerry smartphones –Pushing content to the browser cache User receives no notification when new content is received New content is automatically displayed the next time the URL is accessed Use together with browser channel and browser message push requests to preload cache with external resources © 2009 Research In Motion Limited

16. Browser push Additional considerations when pushing content to the BlackBerry Browser –Defining cache control properties BlackBerry ® Device Software version determines the default length of time the content remains in the pushed content cache Expired content is cleared from cache even if not viewed Use the Cache-Control or Expires to change the amount of time the content is stored © 2009 Research In Motion Limited

17. Browser push Additional considerations when pushing content to the BlackBerry Browser –Transcoding content The BlackBerry MDS Connection Service can be configured to automatically transcode pushed content Transcoding pushed content changes it into more suitable formats for sending over wireless networks and rendering in the BlackBerry smartphone Push requests can override transcoding rules for the BlackBerry MDS Connection Service © 2009 Research In Motion Limited

18. Browser push Additional considerations when pushing content to the BlackBerry Browser –Transcoding content The BlackBerry MDS Connection Service can be configured to automatically transcode pushed content Transcoding pushed content changes it into more suitable formats for sending over wireless networks and rendering in the BlackBerry smartphone For best results, allow the BlackBerry MDS Connection Service to transcode all pushed content © 2009 Research In Motion Limited

19. Browser push Additional considerations when pushing content to the BlackBerry Browser –HTTP headers used by the BlackBerry Browser Include a set of headers to define browser behavior Required in addition to delivery parameters specified in PAP control entity or RIM push headers © 2009 Research In Motion Limited
