Description

FIELD

The invention relates generally to Rich Internet Applications that require custom communications with one another and to management of content used by these applications.

BACKGROUND

Rich Internet Applications are applications that communicate with one another. Part of the management of Rich Internet Applications includes dealing with the demand for constant communication between applications, dealing with any requirements for low latency or real time communications, and content issues. The content issues are especially relevant with client-side content, where the client side content of the Rich Internet Application is updated frequently in response to instructions from a server component.

Current solutions may rely on proprietary server/client frameworks that require licensing or have difficulty scaling. Another current solution relies on a periodic polling mechanism, where each of a set of distributed web-browser based applications must make repeated requests to the server to get the information about the other users, as well as post their own recent actions.

These solutions suffer from a number of issues. They tend to lack customizability, in that they offer a limited amount of customization in the amount and type of information that can be passed between the web browser based Rich Internet Applications and the server components of the system. The also tend to have speed limitations, in that they do not provide real-time communication between the server and the web-browser-based UIs. The latency, or delay in sending and receiving information provides lower performance. Most current solutions limit the total number of participants to a relatively small number, and lack any method of scaling to larger numbers of users. Some of the current solutions require the installation of a proprietary server module to integrate the messaging protocol, and the use of this proprietary server can limit interoperability with other proprietary or non-proprietary systems. Finally, some of these prior solutions require expensive server components, introducing cost limitations.

There is therefore a need to solve the problem of coordinating the actions of numerous widely distributed web application users. A system and method is needed that integrates Rich Internet Applications while at the same time solving scalability, performance, customizability, interoperability and cost issues.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

Communication is an essential aspect of Rich Internet Applications. The described embodiment of a Rich Internet Application communication system is related to Rich Internet Applications that require custom communications with one another. The described embodiments also relate to management of content used by these applications. The innovations herein integrate Rich Internet Applications and improve scalability, performance, customizability, interoperability and cost issues.

FIG. 1 is a diagram illustrating communication system 10. Rich Internet Application communication system 10 includes server system 12, client application 20, web application 14, web application to server link 18, client application to web application link 22 and client application to server link 16. The use of web application 14 allows the load on server system 12 to be reduced, and saves CPU cycles for the end user facing application.

Client application 20 is an application that communicates with other applications, and is typically referred to as a Rich Internet Application. Client application 20 may run on a home computer, a network enabled phone, a personal data assistant, or another device capable of connecting Rich Internet Applications to each other.

Web application 14 is an application that performs archiving and audit trail maintenance, among other functions. Web application 14 cues messages that are not urgent and that may be delayed without impacting the performance of communication system 10.

Server system 12 contains multiple “rooms” to which web application 14 and client application 20 may register and connect, including a control room to which client application 20 must connect. Server system 12 may be made up of a single server, or may comprise multiple networked servers. Server system 12 may be extendable to allow for improved server system performance by adding additional computing power to the system at any time. In one implementation, server system 12 is comprised of a Jabber server running eJabberD. This provides for flexibility and reduces costs by operation under a GNU General Public License. Web application to server link 18, client application to web application link 22 and client application to server link 16 are communication connections between the different segments of the communication system 10. Typically these will be connections of networked processing components through the internet, but they may operate through local area networks, wide area networks, phone networks, satellite communication links, or any other connection for allowing processing components to share information.

FIG. 2 shows multi-user communication system 30. Multi-user communication system is similar to communication system 10 of FIG. 1. Multi-user communication system 30 includes a scalable number of client applications, shown here as 20a, 20b, and 20xyz. Multi-user communication system 30 also includes server system 12, web application 14, web application to server link 18, client application to web application link 22 and client application to server link 16. Here, server system 12 includes control room 24.

On initial startup of each client application 20, the client application 20 connects to server system 12 and authenticates itself as a valid user or registers as a new user. Each client application must join control room 24 on server system 12. Each client application 20 then broadcasts information to control room 24, allowing all other joined client applications 20 to receive the information. Control room 24 may also be used to push content such as presentation slides, video, or other content to client applications 20.

FIG. 3 illustrates a specific implementation of a communication system 50. This Rich Internet Application communication system 50 includes jabber server system 52, weblogic 54, Rich Internet Application 60, web application to server link 58, client application to web application link 62 and client application to server link 56.

Jabber server system 52 includes multiple hardware servers running Jabber software such as eJabberD. The servers are networked together, and must contain a control room. They may additionally run presence rooms, chat rooms, and registration interfaces. Jabber server system 52 is connected to Rich Internet Application 60 through client application to server link 56.

Rich Internet Application 60 contains software for interacting with jabber server system 52 for initialization and registration on initial startup of the Rich Internet Application 60. On startup, Rich Internet Application 60 connects to the jabber server system 52 and authenticates itself as a valid user or registers as a new user. This operates as an in-band registration system that may add new users only when needed and actively used, and avoids pre-configuration on jabber server system 52 due to user registrations and logins.

Following authentication, Rich Internet Application 60 must join the control room contained on jabber server system 52. Rich Internet Application 60 may transmit essential information to this control room for the jabber server system 52 and all other applications to see. The control room may also be used to push new content, alerts, and pop-up messages to users.

Rich Internet Application 60 may operate as a virtual world, which refers to an immersive user experience, with navigation and visual interaction taken from 3-Dimensional, real world parallels. Rich Internet Application 60 may set up virtual world environments for the use of businesses and their customers such as virtual tradeshows, job fairs, product demonstration, partner pavilions, conferences. and other uses in a wider range of areas that are readily implemented. Rich Internet Application 60 includes virtual show locations such as virtual exhibit halls, auditoriums, and booths, any of which may provide a user with access to video, audio, or text presentations.

In interacting with jabber server system 52, Rich Internet Application 60 may also use XMPP presence messages to provide a flexible and extensible mechanism for developers to integrate application specific logic for custom user tracking in a virtual environment. Rich Internet Application 60 joins a presence room after authenticating or registering with jabber server system 52. Rich Internet Application 60 then broadcasts XML-based information to this room, allowing jabber server system 52 and other Rich Internet Applications to receive this information. This allows features such as location tracking of a user in a virtual environment, location logging and analysis, and location based content delivery.

Rich Internet Application 60 may also connect to other chat rooms located on jabber server system 52. One chat room may be a special purpose multi-user chat room defined by XMPP to push content to Rich Internet Application 60 and any other connected applications. The central controller in jabber server system 52 may then push new content updates related to the room to Rich Internet Application 60 and other connected applications in the form of XMPP messages containing namespaced xml content. Based on the xml schema, Rich Internet Application 60 carries out the required operation.

Communication system 50 also contains weblogic 54. Weblogic 54 performs archiving and audit trail functionality that is not required to be real time or near real time. Separation of weblogic 54 functions from the communication interaction of Rich Internet Application 60 with rooms in jabber server system 52 allows the load on the server to be reduces and saves CPU cycles for critical time sensitive applications. Delayed information may also be cued and passed through weblogic 54 for the purpose of providing logging and storage compatibility with systems outside of communication system 50.

In one implementation, weblogic 54 consists of an erlang logger 64 and an application server queue 66. The erlang logger 64 collects all required logging packets and periodically sends them to an application server. Erlang logger 64 additionally contains an internal queue to which it will add the packets and then post them on a specified timeout. If the queue hits its full capacity before the timeout, the modules post the packets to the application server. Both the queue size and the timeout values may be configurable. In one possible implementation, HTTP POST mechanisms are used to send information to the application server. Application server queue 66 is present for queuing and processing of logging information. The logging module on the application server parses all the packets and adds them to application server queues based on the type of information contained. One possible implementation of these queues are JMS queues. JMS queues allow flexibility to delay processing beyond the initial delay from erlang logger 64. Additionally, use of JMS queues and application server queue 66 allows for easy moving of logging processes to different physical machines for improved efficiency. The queue for each different type of information may contain a corresponding Message Driven Beans for processing the incoming data.

FIG. 4 is a diagram illustrating an event center 90 that may be utilized by one or more users 92 that are presented with a presentation by the Rich Internet Application in a system further incorporating the communication system, and one or more presenters 94 who utilize the virtual system to present presentations to the users 92. The users 92 may interact with a registration and lobby modules 80 that permit the users to register with the system and schedule a presentation to view. In response to a successful registration, the user may be presented with a player page 96, such as a web page provided to a client computer of the user, that provides the audio and visual data for the presentation, slides, polls and URLs for the presentation, chat sessions and question and answers for a particular presentation. The data in the player page 96 is provided by the web server 60, the media server 54 and a chat server 98 that provides the chat functionality for a presentation. The presentation data for a live event presentation is provided to the servers 54, 60 and 98 by the presentation manager module 50c. The presenters 94 may utilize the event manager module 50b to reserve an event and/or configure an event. Once the event is reserve and configured, the presentation data is forwarded to the presentation manager module 50c.

FIG. 5 is a diagram illustrating an example of an online presentation client 100 that may be used in conjunction with the communication system for running a Rich Internet Application. The event client 100 may be implemented as a personal computer, workstation, PDA, cellular phone and the like with sufficient computing power to implement the functions of the client as described below. In the example shown in FIG. 3, the event client may be a typical personal computer that may further comprise a display unit 102, such as a CRT or liquid crystal display or the like, a chassis 104 and one or more input/output devices 106 that permit a user to interact with the client 100, such as, for example, a keyboard 106a and a mouse 106b. The chassis 104 may further include one or more processors 108, a persistent storage device 110, such as a hard disk drive, optical disk drive, tape drive, etc., and a memory 112, such as SRAM, DRAM or flash memory. In a preferred embodiment, the client is implemented as one or more pieces of software stored in the persistent storage device 110 and then loaded into the memory 112 to be executed by the processor(s) 108. The memory may further include an operating system 114, such as Windows, and a typical browser application 116, such as Microsoft Internet Explorer, Mozilla Firefox or Netscape Navigator and an event console module 118 (including a slide, polls, survey, URL, Q&A) that operates within the browser application. The client side of the system/apparatus is implemented as HTML and Javascript code that is downloaded/streamed to the client 100 during/prior a virtual tradeshow so that the synchronization of the assets does not require separate client software downloaded to the client.

While the foregoing has been with reference to a particular embodiment of the invention, it will be appreciated by those skilled in the art that changes in this embodiment may be made without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims.
