A new technology

The proposal.
Youcast+.NET – internet and proximity rich content sharing and push solutions.
A platform assists people using devices in WLAN with zero networking setup. When we are talking about
mobile networking, we will immediately think of the 3G, 4G internet access. It is true for most
applications, but not always so true when more and more near at hand or near field communication
(NFC) mobile applications help people in study and work on daily basis. Especially, the weakness is
obvious in some prospective aspects:
1. Security and privacy
2. Efficiency of content publishing.
3. Information Localization, autonomic content and computing.
4. Reliance on the hardware infrastructure.
5. Lacking of real-time collaboration.
6. Centric cloud storage that requires extra internet bandwidth consumption.
As private clouds concept emerging, more and more organizations tend to use the solution to reduce
the dependence on the public cloud for the security, cost or agility reason. As a replacement of public
clouds, it brings up some level of flexibility and privacy; however at the same time, users find some
disadvantages such as costs in licensing and maintenance.
The concept behind youcast agent is not only trying to complement the private cloud solutions shortage
of mobile delivery but also is to involve the devices as part of cloud computing. In the context of
enterprise management or personal productivity, the service-oriented architecture is more critical and
pivotal than the static content itself. Users will look for some dynamic and real-time information which
will be constantly changed from time to time.
Apple bonjour framework enables users to make automatic discovery for computers, devices and
services in the IP network with zero-configuration. Based on bonjour, I developed three types of
prototype agents: mobile agent, interactive message agent and auto agent. With the Youcast prototype
agents, user can share the hierarchical content and push real-time content to device or vice versa in
duplex mode.
In the prototype agents, using Java swing and NIO - the same java technique used by Oracle’s Glassfish
to implement auto and interactive message agent, enable the agents to run on Mac, Windows or Linux
with intensive I/O operation. User is also required to install the Bonjour open source package and jre 1.5
or above. User will be able to share content and links by defining the resource tree in the Youcast auto
agent. The content will advertise and propagate to the devices in WLAN.
Let me discuss how it works and some use cases:

At home
 Scenario #1:
Select the device and drag &drop the files into message agent and the mobile agent will synchronize the
files to the selected device automatically.
Currently the mobile agent is already available for iPhone/Ipad/IPod. Thanks to JmDNS and j2mdns –
bonjour for java and j2me, I will quickly be able to develop Android and Blackberry mobile agent
versions. In addition, the mobile agent provides offline capability which enable users to open and view
files that have been downloaded to the device.

In office
The multiple Youcast agents will link to different intranet resources including web, content, service (such
as printing, NFS) or integration with the messaging system. In addition, Youcast mobile agent will also
be able to integrate to different mobile software: pdf reader, quick office or more productivity tools.
 Scenario #1:
During a product presentation, the presenter can simply push the notes and materials to the audience
instantly by using Youcast message agent.
 Scenario #2:
Advertise some training documents or video by auto agent, employees can download by tapping the
files and read them offline in transition.
 Scenario #3:
Help visitors immediately access product video and guest resource across WLAN with zero
configurations.

In public context
 Scenario #1:
In public places, Youcast message agent will offer the online consumer service instantly. Besides, the
merchant or store owns auto agent combined with Indoor Position System, also known as IPS, push the
sales content to customers based on the vicinity of customer’s device, relevant information or sales
advertisement will pop up on the customers’ device when the users close to the spot. The current

Youcast agent architecture allows the stores to distribute and maintain the self-management content by
utilizing shared WLAN inside a complex of buildings.
 Scenario #2:
Visitors access public library search system and help desk from their own devices when they walk into a
library with little knowledge on their internal servers or networking setup.
Business Model
Youcast mobile agent is free to public, with iAd opportunity. Youcast PC agent is also free to public, with
Ads. Youcast server agents will be charged with licensing fee or the number of users for enterprise.
