Description

The method of Web conference is provided

The application requires the U.S. Provisional Patent Application submitted on May 1st, 2003, be entitled as " Network DownloadSystems " No. 60/467739, and on May 1st, 2003 No. 60/467545, U.S. Provisional Patent Application that submit to, that be entitled as " Network meeting system " right of priority.

Technical field

The present invention relates generally to network communicating system, particularly relate to netmeeting.

Background technology

Traditionally, when on interconnection network, for example holding a meeting on the Internet, the announcement of conference host server and propaganda Session Topic, the time of meeting and place.The network that the interesting user who participates in a conference at the appointed time passes through them connects the adding meeting.

With reference to Figure 1A, the traditional mode of on-line meeting is made up of host server 110, its by the side of attending a meeting 112a-112c separately independently coupling arrangement 114a-114c connect the many side of attending a meeting 112a-112c.This is a Client, and wherein host server connects the many side of attending a meeting or client computer.Under this pattern, a large amount of computational resources is by host server consumption.

Traditional mode can not satisfy current and following interconnection network user movable desired environment dynamically and flexibly.Ideally, the activity level on the specifies Internet is wished a kind of different pattern, shown in Figure 1B.In this ad-hoc mode, do not have host server, and many client computer 118a-118e connect by many coupling arrangement 120a-120e in every way.The advantage of this pattern is the central host server that does not connect client computer.As long as the client computer utilization allows between client computer the application program by interconnection network communication, this network schemer is exactly feasible with desirable.

Can go up the acquisition personal server at computing machine (for example Windows PC) by build-in services device software, wherein said server software for example can be free Microsoft personal server software: personal network's server pws10a.exe on the Windows 95/98/Me or the Intemet Information Server on the Windows 2000/NT/XP (internet information server, IIS) 3.0 or upgrade version.After the installation, if computing machine is connected to interconnection network (for example the Internet), the personal server allows any side of attending a meeting to utilize the webserver (for example website) of this computing machine (for example WindowsPC) as him.

Set up point-to-point the connection (in order to download conference content, for example HTML or XML webpage) general URL (URL(uniform resource locator)) address of attending a meeting and knowing personal server's content of connecting of requiring between any side of attending a meeting and the personal server who is connected to interconnection network.

Present the Internet uses domain name and DNS (name server) to search to make the Internet user from the website or the downloaded content.Domain name is to distribute to the name of fixing numeric IP addresses, and it is as the part of URL (URL(uniform resource locator)) address.For example, domain name stanford.edu represents the numeric IP addresses 171.64.14.203 that fixes.In URL, use domain name to discern specific content, for example webpage.In URL http://www.stanford.edu/index.html, domain name is stanford.edu.The DNS system matches correct stationary digital IP address with domain name, so the Internet user need not to know that its numeric IP addresses just can access websites (for example www.stanford.edu).Then, the website uses default page index.html to form the URL of acquiescence usually, and http://www.stanford.edu/index.html for example is so that allow download content during Internet user's access site.

Many network communication services provider, ISP (ISP) for example, when the computing machine that is connecting connects network, all be that this computing machine (thereby for being installed in the connection personal server in this computing machine) distributes the different network addresss (for example IP address) at every turn, so just cause (for other sides of attending a meeting that will download personal server's conference content) can not predict a specific personal server's URL address.For the computing machine and the personal server that are directly connected to the Internet by certain company or mechanism, also may be remapped or be changed in time in computing machine/personal server's IP address, perhaps depend on machine.In addition, many businesses and institutions have computer network security barrier (being commonly referred to as " fire wall "), to stop undelegated invasion to enter their computer network, and fire wall can be specific computing machine or the personal server changes the IP address, so that use different IP addresses to identify this computing machine or personal server at every turn.

Some commerce and non-commercial service are safeguarded being connected to the network of network server.These webservers of direction of attending a meeting that are connected to network provide them the current network address and other identifying informations.In order to set up peer-to-peer communications, other that are connected to network are attended a meeting and can be obtained this information.Such service comprises the Internet online chatting system (IRC) and the Microsoft side of attending a meeting positioning service (ULS).

Other sides of attending a meeting are initiatively sought by these service request sides of attending a meeting, and need seek from the hundreds of or thousands of sides of attending a meeting that the server that is connected to network in any fixed time is known usually.These services can not make to attend a meeting and can enough limit the identification information of whose addressable this side of attending a meeting.

Deng popular instant message service improved communication system is provided, the side of attending a meeting of the interconnection network of being convenient to be located by connecting is to set up peer-to-peer communications.The position of the side of attending a meeting on interconnection network is still represented with the current network position of the side of attending a meeting.

Regrettably, a problem of above-mentioned service is that if central server (server that for example is used for the instant message service) crashes, the user of all connections just loses their service so.

In addition, second problem relevant with above-mentioned service be, they generally do not provide the unique identification of URL address of personal server's conference content of the side of attending a meeting.Therefore, be difficult with accurately locating specific personal server's content (in order to download the content relevant) fast with meeting.

The 3rd problem is, need all sides of attending a meeting: identical browser assistant program (for example plug-in software) or customized software (be used for all equities with most of client/server meetings) (a) are installed, and perhaps (b) is in conjunction with host server (being used for Client).

The 4th problem be, IP (Internet protocol) telephone speech can lost data packets, and this makes the bad or indigestion of sound quality.

The 5th problem is that the number of connection in multi-multipoint reciprocity video conference is participant's a exponential function, so for most of video conferencing systems, this will become very complicated, so that is unable to cope with several above participants.

Netmeeting 10 is set to comprise various computing machine T and the personal server T and the X (it can be mounted in the server software among the various computing machine T) that can be connected to interconnection network 14 (for example LAN, WAN, the Internet or the like) by various coupling arrangements 16 (for example dial-up line is connected, leased line, WLAN or the like), coupling arrangement 16 can be wired or wireless.Computing machine K and personal server T (and X) can receive from input and the demonstration of participant A and export to participant A, and at least one database server 20 with from least one database server 20 reception information, database server 20 also is connected to interconnection network 14 by coupling arrangement 16 by interconnection network 14 transmission information.Database server 20 also can send and receive information by interconnection network 14.

Participant A start on the computing machine K (and preferred personal server T) be connected to interconnection network 14 web browser/customized software be connected routine 30.Addressing routine 26 preferably resides among the computing machine K (with personal server T), and addressing routine 26 (for example using the C++ software of the customization of Microsoft Windows API (application programming interface)) extracts the IP address of computing machine K (with personal server T) from the HOSTNET structure, the HOSTNET structure is the data structure of being distributed by Windows Sockets, and by c++ programming language Windows function use and storage about the information of given host (host name for example, IP address or the like), when having set up the connection of interconnection network 14, determine the network address (the URL address that the conference content of seeking with the quilt in personal server T or X is downloaded) of computing machine K, and provide the network address (with the URL address) to give web browser (or customized software) and be connected routine 30.

When connecting for the first time via interconnection network 14, web browser/customized software be connected routine 30 transmission notice and give Service-Port watchdog routine (daemon) 22 (for example HTTPD or HTML (Hypertext Markup Language) port monitoring program or be responsible for waited for the program that the request from other parts of the Internet enters), periodically transmit then (with variable interval, for example be provided with) by database server 20, Service-Port watchdog routine 22 can receive input via interconnection network 14, and typically resides in the database server 20.Participant A goes up input user data (participant's name, password or the like) at computing machine K (or personal server T).Described participant A data are sent out and 22 receptions of serviced device port monitoring program from being connected routine 30 together with the described network address (with the URL address) information (coming self-routing routine 26), and being provided for server database 28 (for example Microsoft SQL database), server database 28 is preserved participant's information, network and URL address.

On server database 20, different addressing routine 26 (for example cgi script obtains to seek participant's IP address and be stored in the server database from CGI environmental variance REMORE.sub-ADDR) alternately or is additionally determined the source network address (for example IP address) of the notice that Service-Port watchdog routine 22 receives.Described different addressing routine 26 alternately or additionally provides network (and URL) address to give server database 28 (for example MicrosoftSQL database), and alternately or additionally resides in the database server 20 of preserving network (and URL) address.

The information that report routine 24 in the database server 20 (for example cgi script) retrieval server database 28 is preserved, and give various computing machine K and personal server T (and X) with this information transmission.

Describe a kind of typical operation of netmeeting 10 in detail below with reference to Fig. 2 A, 2B, 3A and 3B.

With reference now to Fig. 2 A,, it shows that the participant A K (with preferred personal server T) that uses a computer is established to be connected (for example LAN, WAN, the Internet or the like) of interconnection network 14 via coupling arrangement 16.To the connection of interconnection network 14 can be the circuit fixed or wireless, and typically arrive network communication services provider via leased line (for example DSL, ISDN, T1, WLAN) or dial-up line (for example POTS, GSM/CDMA/3G), the typical case is ISP (ISP) or telecommunications company.

At least one database server 20 typically is connected to interconnection network 14 continuously via coupling arrangement 16.Database server 20 for one can be provided, and wherein all database servers are by continuous synchronization, to have identical information.

In case participant A is connected to interconnection network 14, participant A just uses web browser (or customized software) and is connected routine 30 and notifies (when connecting for the first time, with variable gap periods ground, for example be provided with at interval then by database server) Service-Port watchdog routine 22: participant A is connected to interconnection network 14.This notice is included as the predetermined unique participant's name of participant A, and it is kept in participant's tabulation of connection by server database 28.This unique participant's name is irrelevant with the computing machine K of participant A use.In one embodiment, this notice can comprise the participant's password that is used to verify, promptly participant A has the right to use unique participant's name.This notice also can comprise other information, for example current network (and URL) address of the computing machine K (with personal server T) of participant A use.

When computing machine K was connected to interconnection network 14, addressing routine 26 (on the computing machine K) was determined the current network address of participant A.Operation addressing routine 26 (on the computing machine K), to use Microsoft Winsock API to extract network (and URL) address of computing machine K (with personal server T) from the HOSTNET structure, the HOSTNET structure is the data structure of being distributed by WindowsSockets, and use by c++ programming language Windows function, with the information of storage about given host, for example host name, network address or the like.When computing machine K is connected for the first time, then with variable gap periods ground, the interval that is provided with by database server for example, addressing routine 26 (on the computing machine K) is passed to network (with URL) address then and is connected routine 30, and it passes to (database) Service-Port watchdog routine 22 then.Current network (and the file-sharing/download URL) address of participant A (just computing machine K and personal server T) is provided for (database) server database 28 then, and it preserves network (and URL) address in the tabulation of participant (for example computing machine T) who connects and conference content download (in personal server T and X).

On database server 20, different addressing routine 26 (for example cgi script obtains to seek participant's IP address and be stored in the server database 28 from CGI environmental variance REMORE.sub-ADDR) alternately or is additionally determined the source network address (for example IP address) of the notice that Service-Port watchdog routine 22 receives.Described different addressing routine 26 alternately or additionally provides network (and URL) address to give server database 28 (for example Microsoft SQL database), and alternately or additionally resides in the database server 20 of preserving network (and URL) address.

Though as mentioned above, described different addressing routine 26 is communicated by letter with (database) server database 28, but described different addressing routine 26 (on database server 20) alternately or is additionally communicated by letter with computing machine K (with personal server T and X), give on the computing machine K (with personal server T and X) web browser (or customized software) be connected routine 30 current network (and URL) address of computing machine K (with personal server T and X) be provided.

Computing machine K provides one group of predetermined (conference content) of being sought of participant A to download for server database 28, and server database 28 is preserved it.Just the participant A from computing machine K receives loading under one group of (conference content) of being sought, server database 28 is just checked (conference content) download list that connects, search any (conference content) of the being sought loading down that is currently connected to interconnection network 14, the typical case is used to be presented at computing machine K.If (conference content) loading down of finding the quilt of connection to seek, server database 28 just makes reporting software 24 (for example cgi script) transmission report to the participant A at computing machine K place, wherein said report typical case comprise unique (conference content) download name and be currently connected to interconnection network 14 and all (conference contents) of being sought that participant A (computing machine K just) is seeking under the URL address (preferably being linked to their hypertext link of URL address) of loading.

Service-Port watchdog routine (daemon) 22 from the connection routine 30 of computing machine K (when connecting for the first time, then with variable gap periods ground, for example change at interval by database server) receive to connect and upgrade, connect to upgrade is that computing machine K is currently connected to interconnection network 14 or disconnects from interconnection network 14 according to network communication protocol well known in the art TCP/IP for example.

With reference now to Fig. 2 B,, it has shown that time loading X is (in personal server X, in order to be easy to read and avoid confusion, to use be different from the name of loading T and personal server T down) with Fig. 2 A is described in the identical mode of participant A (just computing machine K or personal server T) be established to being connected of interconnection network 14.In case loading X (in personal server X) is connected down, (conference content) download list that the quilt that server database 28 connects with regard to inspection is sought and the searching participant of their correspondences are to determine whether loading X (in personal server X) is sought by participant A under (conference content).If server database 28 is checked the participant who connects then, whether be connected to determine that participant A is current.If participant A still connects, server database 28 just makes report routine 24 (for example cgi script) transmission report to participant A (computing machine K just), wherein said report typical case comprise (conference content) sought down unique (conference content) of loading X download name (for example descend loading X) and (conference content) sought under the current URL address (for example 222/D2.HTM, with reference to figure 2B) of loading X.

According to another embodiment of the present invention, server database 28 is checked (conference content) download list, loading wishes to be required permission under these, whether wishes that with loading X under definite (conference content) explicitly allows the information of searching participant request about loading X under (conference content).If (conference content) loading X down requires explicit permission, report routine 24 (for example cgi script) is given permission routine 36 (for example contrasting the customized software that participant's name and/or password are sought in the participant that permits among the personal server X and cipher list inspection) with regard to the transmission permission request, and it typically resides among the personal server T (and X).Permission routine 36 (in personal server X) permission or refusal participant A are to the URL address location with about (conference content) request of other message of loading X down.Permission routine 36 provides grant message to server database 28 then, and database 28 determines what (approval just or refusal permission) will be report routine 24 (for example cgi script) will transmit and give participant A (computing machine K just).

When connecting for the first time, then with variable (for example changing) gap periods ground by database server, Service-Port watchdog routine 22 receives from the connection that is connected routine 30 of personal server T (with X) to be upgraded, connect to upgrade is that (conference content) loading X (in personal server X) down is currently connected to interconnection network 14 or disconnects from interconnection network 14 according to network communication protocol well known in the art TCP/IP for example.

With reference now to Fig. 3 A,, (conference content) that its quilt that has shown that participant A (computing machine K just) operation report routine 24 (for example cgi script) provides is sought be the network URL address of loading X down, describe with reference to figure 2A and 2B as above, set up point-to-point connection, to download loading X (in personal server X) under (conference content) sought.Have (conference content) network URL address of loading X down in case it should be understood that participant A, participant A can set up point-to-point connection and download (conference content) loading X down, and this address and the present invention are irrelevant.

Fig. 3 B is the continuation of Fig. 3 A, and two-way download (or meeting) has been described, wherein preferably the participant A of Fig. 3 A specifies two-way automatic download (Fig. 7 A), the URL address of loading T (connection of the computing machine K that uses from A upgrades 30) afterwards down so computing machine L (being used by participant B) receives (conference content), computing machine L (being used by participant B) is callback personal server T (being used by participant A) promptly, with loading T under the automatic download (conference content).

Alternatively or additionally, set up two-way download in order to use two-way automatic download (in Fig. 3 B and Fig. 7 A), participant B (L uses a computer) but (conference content) that quilt that operation report routine 24 (for example cgi script) provides is sought network URL address of loading T down, describe with reference to figure 2A and 2B as above, set up point-to-point connection, to download loading T under (conference content) sought, the result produces participant A, and (K﹠amp uses a computer; Personal server T) and participant B (L﹠amp uses a computer; Personal server X) two-way (conference content) between downloaded.

With reference now to its 3C,, it is the continuity of Fig. 3 B, and the two-way meeting of multiple spot equity has been described, wherein the participant A of Fig. 3 A specifies N to automatic download (Fig. 7 B), so following generation either way:

A) callback is downloaded automatically: down the URL address of loading T (the connection routine 30 of the computing machine K that uses from A) afterwards to receive (conference content) at computing machine L, M, N, computing machine L, M, N (being used by participant B, C, D respectively) be callback personal server T (being used by participant A) promptly, with loading T under the automatic download (conference content).

B) ring makes (call-around) to download (by computing machine L, M, N) automatically:
