Description
Technical field:
The present invention relates to the wideband multimedia communication technology, it is particularly related to video conference, video communication technology, is a kind of flash network video frequency conference method and system concretely.
Background technology:
The development of the video conferencing technology of IP based network reaches its maturity, and is that the video conferencing system of representative has also begun extensive use to meet relevant criterion such as ITU-TH.323, SIP, and presents the trend of high speed development.Development with other communication products is similar, and two developing stage are also being experienced in the development of video conferencing system and product.
Phase I is that video conferencing system and product begin to use and promote gradually in enterprise-class tools, drives the development of video conference overall market.The representative of consumer in this stage is big private network user and enterprise-class tools, and as office of big ministries and commissions, large enterprise, transnational public group etc., they have the dedicated network of self, has a collection of special personnel that administer and maintain system is managed and safeguards.In the phase I, the emphasis of video conferencing system is to guarantee meeting quality and operation stability, in the consideration of aspects such as system's construction cost, maintenance cost, ease for use, the network interconnection seldom.Along with the continuous propelling of video conferencing system in the progressively universal and deployment of broadband network in enterprise-class tools market, ordinary individual (family) user begins to pay close attention to the product in this field, the operator that with telecom operators is representative begins to consider how to run video conferencing system, at this moment, the development of video conferencing system just begins to enter second stage.
The representative feature of second stage is, operator provides the video conferencing system service platform on Operation Network (public network), medium and small shape enterprise customer on the representative of consumer (certainly the part large business user also progressively transition come) and individual (family) user, they do not have the dedicated network of oneself, and the broadband network that is to use operator to provide inserts public network, does not also possess special management maintenance personnel simultaneously and comes the management maintenance video conferencing system.In second stage, the direct buyer of video conferencing system and product is converted into operator in fact, and operator buys a complete set of video conferencing system and product, and the service that this system and product are converted into self is offered the end user.
In addition, current stream media technology has all adopted udp protocol in the transport layer overwhelming majority, and the UDP transmission can be used three kinds of communication modes: clean culture (Unicast), multicast (Multicst) and broadcasting (Broadcast).Multi-medium data throughput when Network Transmission is very big, if the unicast technique of use side and end is carried out multicast communication, has a lot of defectives.At first, server site must remain the state of intercepting, understanding service request of each client terminal that dynamically adds, and socket intercept the very cpu resource of consumption systems, the too frequent instability that causes system easily of intercepting also can influence the service quality of transfer of data simultaneously; Secondly server site need repeat to send in the face of the same service request of different customer rs sites, and N client requests need take the N network bandwidth doubly, greatly wasted network bandwidth resources.Therefore the unicast communication mode is not suitable for the multicast communication of Streaming Media.On the other hand, the broadcast communication meeting sends to machines all in the local area network (LAN) with packet, and no matter whether they are ready to accept, can cause the wasting of resources of not wanting like this; And because router can block broadcast communication, so broadcast technology only is applicable to the multicast communication of the multi-medium data of not crossing over local area network (LAN).
By contrast, multicasting technology allows to send website and only sends data to a group address, and receiving station only need join this group just can receive data.Because what all receiving stations received is same data flow, therefore greatly reduce requirement to the network bandwidth.The group membership can arbitrarily add or withdraw from grouping at any time according to the wish of oneself.A website can add a plurality of groups simultaneously, and different ports or socket can use multicast address transmission data, thereby realizes that a plurality of application share same group address.Multicasting technology can be avoided repeating to send the broadcast storm that may cause effectively, and can break through the restriction of router, and packet is sent to other network segment.
In theory, existing multicasting technology can be broken away from the restriction of local area network (LAN) really, realizes the media data multicast communication of scale in the wide area network scope.But in actual applications, still there are many restrictions in the application of multicasting technology.At first, multicasting technology needs the support of Routing Protocols such as DVMRP, MOSPF, CBT or PTM, but owing to the consideration to fail safe, the router in the practical application is not all opened multicast services; Secondly, even router has been opened multicast services, but also grace can be incompatible for the agreement that they adopt; Outside two, provide the multicast support can take router resource, thereby increase the weight of the burden of router, reduce the router processing speed, when serious even may cause system crash.Therefore being applied in of multicasting technology do not obtain in the wide area network promoting.
Though above-mentioned video conference respectively has advantage, also exist following problems: 1, need client software is installed, be in security consideration such as some phone, the restriction install software, this has just caused trouble to carrying out video conference.2, point-to-point transmission means (comprising a forwarding): can cause the time-delay of whole video conference system like this because the networking speed of a machine is slow.3, such video conference needs expensive hardware device as support, the maintenance cost height.
Summary of the invention:
A technical problem to be solved by this invention provides a kind of flash network video frequency conference method, and this method is without download client, and the place is not limit, and the personnel of participating in a conference can participate in a conference by the computer of any online.
Another technical problem to be solved by this invention provides a kind of flash network teleconference system, and this system can solve the defective that exists in the above-mentioned existing technology, solves the technical problem that present same category of device can't be realized.
A kind of flash network video frequency conference method, this method comprises the steps:
Make up a meeting supporting layer, this supporting layer is included in that a router by correspondence is connected with Internet has Web server of framework and a plurality of Flash Media Sever2 server on the computer of fixing public network IP address, and on the computer that has fixing public network IP address that another router by correspondence is connected with Internet the framework database server, described a plurality of Flash Media Sever2 server is responsible for the audio frequency and video exchange and audio-visual data is fed back to database server stores, the personnel of participating in a conference use any terminal that is connected with Internet to be connected to Web server and a plurality of Flash Media Sever2 server by the form of web page address, by the SSL cipher mode Web server and a plurality of Flash Media Sever2 server are conducted interviews, participate in a conference.
A kind of Flash network teleconference system, this system comprises:
Router by correspondence is connected with Internet, thereon Web server of framework and a plurality of FlashMedia Sever2 servers and have a fixedly computer of public network IP address;
