For further elaboration is clear by the embodiment of the present invention, provide the preferred embodiments of the embodiment of the present invention below in conjunction with Fig. 2.
Fig. 2 is the application message transfer process schematic diagram based on RTP expansion of preferred embodiments, and with reference to Fig. 2, in this preferred embodiments, described first is applied as terminal staging application, and described the first application data is real upgrade data; Described Extended Protocol is RTP Extended Protocol; Described the first packet is RTP packet; Described second is applied as video conferencing application; It is the port-mark that video conferencing is applied the port of opening that described the first port is designated described fire compartment wall;
Described first terminal includes application upgrade module 201, upgrading adaptation module 202, demultiplexing module 203, Multiplexing module 204, becomes bag module 205, RTP sending module 206, becomes frame module 207, order module 208 and RTP receiver module 209 with described first object terminal.Wherein,
Upgrading adaptation module 202, is mainly the interface of coupling application upgrade module 201 with other modules, namely does interface conversion in application upgrade module 201 with between other modules.Because application upgrade module 201 modules may be by modes such as HTTP or FTP, so upgrading adaptation module 202 has been done an adaptation between the interface of the interface of application upgrade module 201 and demultiplexing module 203, Multiplexing module 204 modules;
Multiplexing module 204, mainly to generate checking data for the upgrade data from application upgrade module 201 that upgrading adaptation module 202 sends, and the checking data of upgrade data and generation is multiplexed with to multiplex data, then multiplex data is passed to RTP sending module 206;
Become bag module 205 for generating one or more network packet according to frame of video and sending to RTP sending module 206;
Become frame module 207 for recovering frame of video from the one or more network packet from order module 208;
Wherein, the effect of control and/or checking data is to provide the reliability of upgrade data transmission.Controlling data can be for controlling indication information, for example, for single RTP, expansion cannot be carried the situation of the whole application data bag that application upgrade module 201 produces, receiving terminal receives whole application data bag and can indicate which or which part of this whole application data bag also not receive to transmitting terminal in the time not receiving whole application data bag in order to be judged whether, can in this RTP expansion, add some and control indication information, such as the length of whole application data bag, the skew of the application data block of carrying in this RTP expansion in whole application data bag etc., so that receiving terminal judges whether to receive whole application data bag, if not, can from backward channel, send the repeat requests for the part not receiving.
Particularly, interactive interfacing data and control that application upgrade module 201 can provide according to upgrading adaptation module 202; Upgrading adaptation module 202 is mainly that shielding sends the detailed information receiving, the interface programming that the application of terminal only need to be exposed for upgrading adaptation module 202, and do not need to take into account the specific implementations such as multiplexing, demultiplexing below, but upgrading adaptation module 202 also can provide certain constraint to reduce the complexity of bottom layer realization, such as expanding transmission of information for RTP, be confined to the transmission in IP network, the data volume once transmitting just try not to exceed MTU and the deduct length of some dead loads, to avoid the problems such as network burst.
Thick line in Fig. 2 represents data, and fine rule represents to control.The control here refers to the control of flow process control, namely controls the how processed processing of data.
In this preferred embodiments, described multiple target terminal comprises the terminal of not supporting RTP Extended Protocol, this terminal comprises into bag module 205, RTP sending module 206, becomes frame module 207, order module 208 and RTP receiver module 209, thereby generates in the conventional mode the RTP packet that RTP packet and processing receive.So, this terminal cannot extract described the first application data from the RTP packet receiving, also just cannot generate the feedback information of described the first application data, correspondingly, in the RTP packet that this terminal sends to described first terminal, can not comprise and utilize RTP Extended Protocol to encapsulate data after the encapsulation obtaining, thus, described first terminal receives the RTP packet that certain terminal in described multiple target terminal sends, can judge in this RTP packet, whether to comprise and to utilize RTP Extended Protocol to encapsulate data after the encapsulation obtaining, if, determine this terminal support RTP Extended Protocol, otherwise, determine that this terminal do not support RTP Extended Protocol.
Based on the above-mentioned module in this preferred embodiments, the application message transfer process based on RTP expansion that this preferred embodiments provides specifically comprises the steps:
Steps A. arrange a set of RTP Extended Protocol, all terminals or observe this agreement, or abandon this agreement;
Step B. holds one can be by means of the meeting of MCU forwarding data, for example, and single-image multipoint conference;
The user of step C. terminal A initiates application-specific from interface, for example, and terminal staging application;
The application upgrade module 201 of step D. terminal A, with 202 communications of upgrading adaptation module, sends to Multiplexing module 204 upgrade data;
Step e. Multiplexing module 204 generates control and/or the checking data of upgrade data, control and/or checking data are obtained to multiplex data together with multiplexing with upgrade data, and multiplex data is submitted to RTP sending module 206, the load that RTP sending module 206 utilizes RTP Extended Protocol to expand using multiplex data as RTP is added to the RTP packet that becomes bag module 205 to send or the payload of this RTP packet is abandoned or replaced with the RTP packet after the renewal obtaining after blank screen or blue screen data, thereby generate the RTP packet after adding, then the RTP packet bag after the interpolation of generation is sent via fire compartment wall,
Step F. the user of terminal B is enabling after application-specific, the RTP packet of receiving is given order module by the RTP receiver module 209 of terminal B, the RTP packet after sequence is given demultiplexing module 203 by order module, demultiplexing module 203 is utilized RTP Extended Protocol, from the RTP packet sequence, obtain the multiplex data as the load of RTP expansion, and demultiplexing goes out upgrade data from multiplex data, then upgrade data is seen through to upgrading adaptation module 202 and submit to application upgrade module 201.
For upgrade data recipient, if cannot understand RTP expansion, process normally, what these growth daties were silenced abandons, and whether sender can be had or not and be judged it and support by recipient's feedback.Owing to being structured in insecure UDP transmission, carry out so send periodically, after being sent all data, can then from the beginning send these data, so that recipient has an opportunity to receive all data.And recipient's state feedback is continually during selected seeing to repeat to send to offset the impact of packet loss.So final all data always can arrive safe and sound.Terminal can pass to other terminal by application upgrade data by the mode of independent calling, also can application upgrade data be passed to other terminal to accelerate this application upgrade process, for user provides convenience by the mode of broadcast.
On the above-mentioned process base of this preferred embodiments, provide again a more specifically example below, this example comprises the steps:
Step a: at multipoint control unit (Multipoint Control Unit, MCU) on, hold the suitable meeting of a same ability, speed can be larger, can cause like this application message transfer rate larger, but guarantee in single-image pattern, the media processing of MCU is only just media forwarding like this, and does not apply the measures such as transcoding.
Step b: have terminal to apply chairman the broadcast oneself of upgrade data, make other-end can receive the data of chairman's end by broadcasting this operation.
Step c: chairman sees by continuous choosing other are brought in and obtain the media data of designated terminal, and the upgrade data in the multiplex data of the load of RTP expansion is extracted.What extract here, is generally feedback information.
Certainly,, if data are not utilized RTP Extended Protocol to encapsulate data after the encapsulation obtaining in the packet receiving, show that this terminal do not support the specific RTP Extended Protocol of user.Particularly, because whether RTP uses Extended Protocol can be determined by of a head field, find the not set of this field when receiving terminal, just know without growth data.So, judge whether to have in packet and utilize RTP Extended Protocol to encapsulate the mode of data after the encapsulation obtaining data to be specifically as follows: judge in this packet, whether to have used RTP extended field, if so, have in this packet and utilize RTP Extended Protocol to encapsulate data after the encapsulation obtaining data; Otherwise, in this packet, data are not utilized RTP Extended Protocol to encapsulate data after the encapsulation obtaining.
Steps d: when all terminals are all in having reported or do not supported under the state of RTP Extended Protocol, application has just completed, and can present final result to user, certainly, intermediateness also can present on the interface of chairman's end, has seen user's request.For example, in the time determining the state of certain terminal in having reported or do not support the state of RTP Extended Protocol, on the interface of chairman's end, just present mark and the residing state of this terminal of this terminal.
In addition, due to the restriction of fire compartment wall, terminal room may have many information that needs transmission, all need to be by means of the mode of this RTP expansion transmission.For example, the configuration of terminal or the non-standard information of some terminals mutual, these are applied in the situation without fire compartment wall and are directly connected to terminal, such as extracting terminal document, can use standard File Transfer Protocol, but these application that had firewall restriction now.
This preferred embodiments has mainly solved in the situation that current fire compartment wall adds protocol application server, and a lot of terminal maintenances application cannot be opened the problem of fire compartment wall.Pass through, using a terminal in meeting as agency, application data to be expanded to this transmission tunnel by RTP and transmit, some functions before realizing, such as upgrading and state such as obtain at the function.In upgrade application, by this role of applying broadcasting person, data are sent to multiple terminals simultaneously, can accelerate the to upgrade speed of this application, see by choosing, obtain the selected feedback information of seeing end, can guarantee also can make transfer of data to obtain and ensure in application layer in the situation that of packet loss.In information gathering application, although can only do man-to-man mutual, also can be than cannot be many easily from external linkage and maintenance terminal.
