• On-Demand Extended Business Collaboration Enablement With Web Services and Business Grid (Chief Architect)
  
  
• Web Services Hub Framework and E-Sourcing Enabling Technologies (Chief Architect)
  
  Summary: Web Services Hub Framework (a.k.a. Managed E-Hub) is a network-based utility. Connect once and trade anywhere. It provides a secure, reliable connection hub to the eco-system of market places (buyers, sellers, solution utilities, private exchanges, public market places). It provides the infrastructure for the integration of internal systems with business-critical third-party application and Web Service providers at low-cost and high-accuracy transactions. Further, it provides the housing infrastructure for trading services such as UPS, Payment services, BE4WS. These services may be provided by partners or IBM. It is also a platform to aggregate services based on BPOL (Business Process Outsourcing Language) to enhance service outsourcing capability: e-business on demand.

• WebSphere Business Integrator (WBI) and UPS E-Commerce Tools Integration Using Web Services (Chief Architect)
  
  Summary: In recognition of the increasing importance of globalization and the resulting need for greater, faster and more flexible communications, a framework is required to allow any company to establish itself in no time or make optimum use of their legacy applications and run efficiently with minimal cost input. This case study presents such a framework called ELPIF for e-logistics processes integration based on Web Services via incorporating (1) common alliance interface (2) adaptation layer; and (3) dynamic data binding mechanism. This framework can be adopted as a new service delivery model that uses a design pattern, business process inheritance and solution templates. The interaction between the e-logistics processes and business process manager that orchestrates e-logistics processes in an e-business solution will be described in this paper. A transportation planning in the purchase order management process of a B2B solution is used as an example to illustrate the usage of ELPIF by encapsulating United Parcel Service (UPS) on-line XML Tools as Web Services.
  
  

• Grid Computing Solutions (Chief Architect)
  Invited articles: Developing Grid applications, Part 1 and Part 2. 

• IBM WebSphere Business Integrator (WBI) and Web Services Integration Demo for IBM Dynamic E-business Announcement on May 14, 2001, XML DevCon 2001 in April, and JavaOne 2001 in June (Chief Architect)
  
  Summary: A working B2B system is presented for demonstrating the feasibility of the proposed advanced UDDI search engine (BE4WS) for dynamic e-business integration. In this system, buyer can use Web Services to create purchase order and get the details of the created purchase orders. Meanwhile, suppliers can check the purchase order information, find transportation providers, obtain quotes for service, and assign the provider to a specific purchase order. Especially, an intelligent shipping agent using BE4WS is used to find the potential transportation service providers who serve the country of dispatch of the purchase order from a private UDDI registry.

• E-Commerce Solutions for Interactive Digital Television – IBM HotMedia iTV (Chief Architect)
  
  Summary: IBM Interactive TV transforms the traditional broadcast television with one-way feed of information and entertainment into the enhanced TV mode with richer, two-way television experience. This solutions consist of HotMedia® TV technology and other IBM backend services such as WebSphere Commerce Suite, Content Manager and other DB2 applications.
  HotMedia® TV is an architecture and toolset for the development of interactive TV content creation, management, distribution and related interactive offerings. Using digital video as a starting point, data can be embedded in the transport stream and synchronized with the video and audio content of the stream. Data is synchronized with specific coordinates (spatial) and specific frames (temporal) of the video. We designed and implemented HotMedia TV Studio Live to embed data into MPEG-2 transport stream in real-time and enable interactive TV audience and program rating in real-time using multi-level tracking methods, systems and program products.

• E-Commerce Solutions for Internet Media - IBM supported product: HotMedia (http://www.ibm.com/hotmedia/) (Core Architecture Team Member)
  
  Summary: HotMedia is a toolkit for creative professionals, designed to enrich e-business applications with rich media. With HotMedia you can add special effects, such as 360-degree views, multi-track animations, streaming audio and video, panning and scrolling, and zoomable multi-resolution images. Add interactions and hot links, and assemble the entire experience into one file, easily added to a web page and delivered over today's networks. HotMedia dynamically determines the minimal code and data content which is needed and downloads it progressively. This plug-in-free Java tool also includes e-commerce-enhancing features designed to attract, retain and track customer mouse clicks. We invented an advanced tracking framework for rich media and an advanced in-banner secure transaction system. The invented web content pre-fetching and real-time display technology, synchronized multimedia and streaming web content, was implemented in released HotMedia Audio authoring tool & Java player.

• E-Commerce Voice Solutions - Internet Telephony Gateway (Product Manager)
  
  Summary: The E-Commerce Voice Solutions realized the seamless connection between the broadly used Internet and the regular Public Switching Telephony Network (PSTN) so as to save large amount cost of long-distance call. It has been an industry focus within the latest years. The first prototype system based on Microsoft's NetMeeting that conformed with H.323 standard has been delivered in 1997. This system includes the Internet Telephony Gateway Server software and Internet Telephony Client software. Using this system, you can make a phone call from Internet PC to a regular POTS phone. The voice quality is pretty good. IPO2U.com has commercialized this technology.
  
• Internet Real-time Conference (Product Manager)
  
  Summary: Internet Real-time Conference based on the IOP (Internet Open Platform) architecture, standard interface and cross-platform programming language can be used as a tool for creating a virtual conference over Internet. For example, it can easily process multimedia conference preparation via Internet; and provide discussion forum, Java chat room to attendees. It has a suite of potential applications: Internet office solution, Group communication and information sharing, workshop, and interactive community media. The newer version enabled multimedia content integration with Internet Real-time Conference system and powered GISSIC’97 over the Internet. Based on this system, we proposed a High Bandwidth Distance Learning Solution for Internet 2 .

• E-Commerce Solutions for Hyperlinked Video Content - IBM HotVideo (Project Lead)
  
  Summary: IBM HotVideo extends the concept of hyperlinks from text and images to video, providing hyperlinks to hot spots in digital video. IBM HotVideo technology contains two components: The HotVideo Maker (Maker) and the HotVideo Player (Player). The Maker utilizes familiar point and click methods for the creation of HotVideo content. The Player allows for intrusion-free viewing of HotVideo content while alerting users to the location of hyperlinks within the frames. An indicator highlights the hot link locations in the video; the indicator is green when hot links are not present and red when hot links are present. Users can choose to either browse the hot link locations or continue to view the video as-is. This product has been released in June 1998 (See http://www.software.ibm.com/net.media/). CNN Interactive, was one of HotVideo’s initial pilot sites. USA Today reported on this invention in the cover story on April 2, 1999.
  
• SLIM: Software based Low-bit-rate Interactive Multimedia platform (Project Lead)
