It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present disclosure.

Accordingly, the present disclosure may be embodied in the following forms, namely: complete hardware, complete software (including firmware, resident software, micro-code, etc.), or a combination of hardware and software.
In order to solve the problems in the prior art that the deployment cost is high when a special transmission line is deployed to transmit data packets in a video conference in order to ensure the quality of video conference service. The present disclosure provides a transmission method of data packets in a video conference, which is applied to an access node of a video conference acceleration platform, so as to realize that all data packets interacted between a video conference client and a video conference server in a video conference session are accessed to the video conference acceleration platform, and further, the video conference acceleration platform can provide safe, stable and efficient network service for data transmission in the video conference process.
In the video conference process, interaction based on an H.323 multimedia communication protocol can be performed, and the method and the device can be applied to video conference scenes under different communication protocols according to actual needs, and the method and the device are not repeated here.
In the embodiment of the disclosure, referring to fig. 1, an interaction diagram between each node of a video conference client, a video conference server and a video conference acceleration platform in the embodiment of the disclosure is illustrated, and an interaction party involved in a transmission process of a data packet in a video conference includes the video conference client, the video conference server and the video conference acceleration platform formed by nodes deployed in each area.
The video conference client in the present disclosure refers to a terminal application installed on a terminal device of a user, which is capable of performing video interaction, or a web (World Wide Web) service accessed through a browser of the terminal device, where the terminal device may be various electronic devices, such as a mobile terminal, a fixed terminal, or a portable terminal, for example, a mobile phone, a desktop computer, a notebook computer, a tablet computer, or the like. A user may request creation of a video conference via a video conference client to open a video conference session, which is synchronously ended when the video conference has ended the service.
The video conference service end in the disclosure refers to a background management service application capable of providing services for a video conference, and the background management service application can be deployed on an independent physical server or a server cluster, and the video conference service end is a generic term of various background management services.
It should be understood that the architecture of the videoconference client and the videoconference server in the present disclosure is merely an example, the present disclosure is not limited thereto, and specific architectures are determined by the videoconference service provider, and may be different from each other.
The video conference acceleration platform is composed of nodes distributed in various areas, wherein each node can be composed of one or more servers, the nodes can be mutually connected in a communication mode, and a network topology can be built according to requirements, therefore, the video conference acceleration platform can be also called a video conference acceleration network, can provide network services such as data acceleration, data security and the like for clients, and can be a CDN (Content Delivery Network) network or a network built based on SD-WAN (Software-Defined Wide Area Network) technology in some implementations. The nodes of the video conference acceleration platform can mutually detect each other to acquire link quality between every two nodes, and then a preferable transmission link for transmitting data packets between the video conference client and the video conference server can be planned according to the link quality between the nodes, wherein the link quality can comprise time delay, packet loss rate, bandwidth, cost and the like.
Preferred embodiments of the present disclosure will be described in further detail below with reference to the attached drawing figures:
referring to fig. 2, a flow chart of a video conference acceleration method provided by an embodiment of the disclosure is shown, and the method is described below with reference to fig. 2:
step 201: and receiving a data packet sent by the video conference client at a local first session receiving address, determining an accessed video conference server according to the stored association relation between the first session receiving address and the video conference server, and acquiring a transmission link reaching the video conference server from the video conference acceleration platform.
It should be noted that, the first session receiving address in this step refers to an address where the access node receives a data packet sent by the videoconference client, where during one videoconference session, the videoconference client may send a plurality of data packets, where each data packet includes different contents, for example, the content carried in the data packet may be: the RAS message, or call signaling, or multimedia communication control message based on h.245 protocol, or multimedia data containing video conference content, etc., so that the first session receiving address is a generic term for each address where the access node receives a data packet, and there may be a difference in address information specifically corresponding to the first session receiving address for different data packets.
In order to enable a first session data packet sent by a video conference client to successfully access a video conference acceleration platform in a session, in this embodiment of the present disclosure, each node in the video acceleration platform is preconfigured with a local fixed IP (Internet Protocol ) address and a port for receiving the first session sent by the video conference client, and an association relationship between the fixed IP address and the port and a video conference service end for processing the first session data packet, that is, each node is preconfigured and stores a local fixed IP and a port, and an association relationship between the fixed IP address and the port and a video conference service end capable of processing the session data packet, where, since the fixed IP address and the port are local addresses of each node, the fixed IP address and the port configured on each node are different from each other, and since the video conference service end for processing the first session data packet of the same video conference service end is fixed, the association relationship between the fixed IP address and the video conference service end for processing the first session data packet and the video conference service end can be obtained from a video conference service provider in advance, thereby establishing an association between the fixed IP address and the port.
In the actual video conference process, since each node is configured with a first session receiving address for receiving the first session of the video conference client, that is, a local fixed IP address and port, and video conference service side information associated with the local fixed IP address and port, no matter to which node the first session data packet of the video conference client is sent, the data packet of the session can be ensured to be effectively transmitted to the corresponding video conference service side.
In addition, DNS (Domain Name System) information between each fixed IP address and a video conference service domain name is preset to implement that a first session initiated by a video conference client is dispatched to a video conference acceleration platform through DNS, specifically, before the video conference client sends a data packet of the first session of the video conference, the video conference acceleration platform needs to obtain a destination IP address of the data packet of the first session through sending a DNS resolution request, the video conference acceleration platform can intercept the DNS resolution request first, comprehensively consider the location of the video conference client and the load condition of each current node, determine a node receiving the first session of the video conference client as an access node in the video conference, wherein the access node can be the node closest to the video conference client and having processing capability, and return the preset fixed IP address on the access node to the video conference client as a result of DNS resolution, so that the first session sent by the video conference client can be received by the access node allocated, and the video conference acceleration platform is accessed by the video conference client.
After determining that the data packet of the first conference actually accesses the video conference server from the local record according to the first session receiving address, the access node obtains a transmission link reaching the video conference server from a video conference acceleration platform, and the process of determining the transmission link is described as follows:
the method for the access node to acquire the transmission link includes two modes: first, actively creating a transmission link by an access node; second, a transmission link is created by a management node in the video conference acceleration platform and issued to the access node, wherein the management node may issue the transmission link to the access node upon receiving a link issue request from the access node.
Specifically, the process of creating the transmission link may include constructing a preset number of candidate transmission links reaching the video conference server from the access node according to each node included in the video conference acceleration platform, and screening the transmission links from the candidate transmission links based on a preset routing policy, where the preset routing policy may include random selection or selection according to link quality, as described above, each node of the platform may determine link quality between nodes by detecting each other, based on this, link quality of each candidate transmission link may be obtained according to link quality between each node included in the candidate transmission link, so as to select at least one candidate transmission link meeting a preset condition as a transmission link, where the preset condition may be a determined threshold requirement, such as a delay requirement, a packet loss rate requirement, or a criterion reached after calculating by integrating each quality parameter, or a preferred selection, such as selecting one or more of best quality, where the disclosure is not limited.
It should be noted that the number of transmission links acquired by the access node may be multiple, for example, two transmission links may be acquired simultaneously for transmitting the data packet, and specifically, a master-slave policy may be adopted to use the links, or transmission may be performed simultaneously based on multiple links, so as to improve stability of data transmission.
In one implementation, before constructing the candidate transmission link, the access node may first determine whether an effective transmission link for the videoconference server is cached locally, and if so, directly determine the cached effective transmission link as the transmission link; otherwise, the step of constructing the candidate transmission link is executed. When judging whether the local has cached an effective transmission link aiming at the video conference server, determining whether a corresponding transmission link has been selected for the current video conference session, and if so, determining that the effective transmission link has been cached.
Step 202: and forwarding the data packet to the video conference server side through a transmission link.
The access node of the video conference acceleration platform acquires a transmission link of the data packet and sends the data packet to the video conference service end through the transmission link, and because the transmission link is provided by the video conference acceleration platform, corresponding network services such as safety guarantee, stability, speed and the like can be provided for the data packet in the transmission process.
It can be understood that after the video conference server receives the data packet through the transmission link, the data packet fed back by the video conference server for the data packet will also be forwarded through the transmission path to reach the access node, so that the data packet sent by the video conference server in one session is synchronously realized, and the video conference acceleration platform provides network service.
Step 203: receiving a feedback data packet sent by a video conference server, modifying the target address in the feedback data packet into a second session receiving address when the feedback data packet is determined to carry the target address, and forwarding the modified feedback data packet to a video conference client through a transmission link.
Correspondingly, when the access node determines that the feedback data packet does not carry the target address, the access node can directly forward the feedback data packet to the video conference client.
Specifically, the access node receives the feedback data packet sent by the video conference server through the transmission link, and can detect whether the service data of the feedback data packet carries a target address, and it is worth noting that the target address is a service data part carried in a data packet message and is not quintuple information of a message header, and the target address indicates to the video conference server that the video conference client initiates the next session interaction by taking the target address as a new target address after receiving the feedback data packet.
And when the feedback data packet carries the target address, creating and managing the association relation between the target address and the local second session receiving address. Specifically, the access node may select an idle dynamic IP address and port or a newly created local dynamic IP address and port from the local as the second session receiving address, establish and store the association relationship between the dynamic IP address and port and the destination address, and at the same time, the access node may clear the association relationship and release the dynamic IP address and port when determining that the destination address fails, and it should be noted that, the fixed IP address and the dynamic IP address in the present disclosure are both local IP addresses of the access node, and the fixed and dynamic IP addresses are only used to distinguish whether the IP address is preconfigured or temporarily created in the session, so that the dynamic IP address and port are different from the fixed IP address and port described above, are temporarily allocated according to the session, and may be released.
That is, in the embodiment of the present disclosure, the fixed IP address and port are the relative concepts to the dynamic IP address and port, so that the established association relationship does not end with the session, and the dynamic IP address and port are the same as the destination address, that is, the dynamic IP address and port are only used to distinguish the destination address corresponding to the transmission in the video conference process, that is, the video conference server to which the transmission is required. The dynamic IP address and port can be randomly allocated as long as it is guaranteed that the IP address and port are not occupied by other sessions, so that there is no need for persistence.
In the embodiment of the disclosure, the communication session between the node of the video conference acceleration platform and the video conference client and the video conference server may be performed based on a TCP protocol or may be performed based on a UDP protocol, and the video conference client and the video conference server may actively close the session or close the session overtime according to a mechanism of the protocol itself. Specifically, after establishing the association relationship between the regenerated local second session receiving address and the target address, the video conference acceleration platform clears the association relationship and releases the second session receiving address when determining that the target address fails, wherein the manner of determining that the target address fails can be any one of the following:
a1, determining that the session with the video conference client is closed.
Specifically, when a user operates to close a video conference on a video conference client, in response to the closing operation of the video conference, the association relationship between each dynamic IP address and port established for the session on an access node and a corresponding target address is deleted.
A2, determining that the session with the video conference server is closed.
Specifically, when the video conference is closed by operating on other video conference clients which interact with the video conference client, the association relationship between each dynamic IP address and port established for the session on the access node and the corresponding target address is deleted in response to the closing operation of the video conference.
A3, determining that the waiting time for waiting for the video conference client to send the data packet reaches a set first time threshold.
Specifically, after determining that the duration of waiting for the video conference client to send the data packet reaches the first duration threshold, the video conference acceleration platform can automatically treat the current session as the end, and delete the association relationship between each dynamic IP address and port established for the session on the access node and the corresponding target address.
And A4, determining that the waiting time for waiting for the video conference server to send the data packet reaches a set second time threshold.
Specifically, after determining that the duration of waiting for the video conference server to send the data packet reaches the second duration threshold, the video conference acceleration platform can automatically be regarded as the end of the current session, and the association relationship between each dynamic IP address and port established for the session on the access node and the corresponding target address is deleted.
Thus, after the target address fails, the generated dynamic IP address and port are released, so that the address information can be reused, and the address resource is saved.
The foregoing steps 201-203 disclose a processing procedure of a data packet generated in one data interaction between a video conference client and a video conference server by an access node in a video conference acceleration platform, and it can be understood that in a video conference session, multiple data interactions exist between the video conference client and the video conference server, and the access node can process each data interaction based on the foregoing method, so that all the data packets generated in the video conference session can be transmitted via a transmission link provided by the video conference acceleration platform, thereby implementing a full-course network service, such as acceleration, security, and other services, for the video conference.
Based on the video conference acceleration method disclosed by the embodiment, all data packets interacted by the video conference client and the video conference server in one video conference session can be transmitted by a transmission link provided by the video conference acceleration platform, so that network services such as acceleration and the like are provided for the data packets, and the video conference client and the video conference server can be accessed to the video conference acceleration platform without any additional configuration.
The above method will be exemplified with reference to an example.
Referring to fig. 3, a schematic diagram of data interaction in a video conference in an embodiment of the disclosure is shown.
S301: the videoconference client sends the RRQ message.
Specifically, in the process of the video conference based on the h.323 protocol, the video conference client first registers with the video conference server through a registration request (Registration Request, RRQ) message, and in the embodiment of the present disclosure, the destination address of the RRQ message sent by the video conference client may be an address on a certain node (access node) in the video conference acceleration platform through DNS scheduling, so that the video conference acceleration platform may receive the RRQ message.
Step S302: and the video conference acceleration platform sends the RRQ message to the video conference server.
Specifically, the access node of the video conference acceleration platform may determine, according to a fixed IP and a Port (e.g., IP0: port 0) of the received data packet and a locally preconfigured association relationship, a video conference server S0 associated with IP0: port0, and then plan an optimal transmission link from itself to reach the video conference server, and then transmit the RRQ message to the video conference server S0 via the optimal transmission link.
Step 303: and the video conference server side sends a feedback RCF message to the video conference acceleration platform.
Specifically, after receiving the RRQ message from the optimal transmission link, the videoconference server S0 responds to the RRQ message, that is, feeds back a registration acknowledgement message (Registration Confirm, RCF), and the RCF message is transmitted to the access node based on the optimal transmission link, where the RCF message includes the destination address (e.g., SIP1: SPort 1) of the videoconference server S1 accessed by the next session.
Step 304: the video conference acceleration platform modifies the target address carried in the RCF message.
Specifically, the access node of the video conference acceleration platform modifies the target address carried in the RCF message into a local receiving address (for example, IP1: port 1) different from IP0: port0, and establishes and stores the association relationship between IP1: port1 and SIP1: port 1.
Step 305: the video conference acceleration platform sends the modified RCF message to the video conference client.
Specifically, the access node forwards the modified RCF to the videoconference client.
Step 306: and the video conference client sends call information such as Setup and the like to the video conference acceleration platform.
Specifically, after the video conference client receives the modified RCF message, a call message such as Setup for establishing a call can be sent to the destination address IP1: port1 in the RCF message according to the indication of the RCF message, so that the access node can receive the call message such as Setup from IP1: port1, and based on this, the data packet sent by the video conference client is received by the video conference acceleration platform again.
Step 307: and the video conference acceleration platform sends the received call signaling such as Setup and the like to the video conference server.
Specifically, after receiving call messages such as Setup sent by a video conference client from an IP1: port1, an access node determines a target address associated with the IP1: port1, that is, SIP1: port1, from a locally stored association relationship, and sends a received data packet containing call messages such as Setup to a video conference server S1 pointed by SIP1: port1 through a previously planned optimal transmission link.
Step 308: and the video conference server side sends the call response message to the video conference acceleration platform.
The videoconference server S1 may answer the received call message and send call answer information, where the call answer information is also transmitted based on the optimal transmission link, so as to reach the access node, and the call answer message may specifically be: the Call is handling Call precedent, alert, connect, etc., and carries an IP address and port of the videoconference server S2 for h.245 negotiation, e.g. SIP2: port2, in the Call answer message.
Step 309: the video conference acceleration platform modifies the IP address and port contained in the call response message to a locally regenerated second session receiving address.
Specifically, the access node receives a call response message fed back by the video conference server from the optimal transmission link, creates a new receiving address different from the receiving address when determining that the call response message contains the IP address and the Port of the video conference server for h.245 negotiation, for example, IP2: port2, and establishes and stores the association relationship between IP2: port2 and SIP2: port2. Meanwhile, SIP2: SPort2 carried in the call response message is modified into IP2: port2.
Step 310: the video conference acceleration platform sends the modified call response request to the video conference client.
Specifically, the access node may forward the modified call answer message to the videoconference client.
Step 311: the video conference client sends an H.245 message to the video conference acceleration platform.
Specifically, the videoconference client can send h.245 messages to IP2: port2 based on the received call answer messages, performing capability negotiation, master-slave decision, and media channel establishment.
Step 312: the video conference acceleration platform sends an H.245 message to the video conference server.
Specifically, after receiving the H.245 message from the IP2:Port2, the access node of the video conference server can determine the IP address and Port of the video conference server S2 used for H.245 negotiation based on the association relationship stored locally, and the SIP2:SPort2. And transmitting the H.245 message to a video conference server corresponding to the SIP2:SPort2 via the determined optimal transmission link.
Step 313: and the video conference server side sends an H.245 response message to the video conference acceleration platform.
Specifically, after receiving the h.245 message, the videoconference server generates an h.245 response message, where the h.245 response message includes a message such as an open logical channel (Open Logical Channel, OLC) and an open logical channel acknowledgement (Open Logical Channel Ack, OLCA), and further sends the h.245 response message carrying the IP address and the port (e.g., SIP3: port 3) of the media channel to the access node via the optimal transmission link.
Step 314: the video conference acceleration platform modifies the IP address and port of the media channel carried in the H.245 response message into a locally regenerated second session receiving address.
Similarly, after receiving the h.245 response message, the access node creates a new receiving address, such as IP3: port3, which is different from the above receiving address, and establishes and stores the association relationship between IP3: port3 and SIP3: port3. Meanwhile, SIP3:SPort3 in the H.245 response message is modified into IP3:Port3.
Step 315: the video conference acceleration platform sends the modified H.245 response message to the video conference client.
Specifically, the access node forwards the modified H.245 response message to the video conference client, and further completes the early negotiation step of the video conference, thereby entering into the normal video conference.
Further, during the video conference, the video conference client accesses the media channel established by the video conference server through the video conference acceleration platform and sends media data packets such as audio and video to the media channel, so that the access node of the video conference acceleration platform forwards the data packets to the SIP3: SPort3 of the media channel of the video conference server through the optimal transmission link, and simultaneously, the media data packets fed back by the SIP3: SPort3 of the video conference server are reversely sent to the video conference client according to the original path until the video conference is finished.
It should be noted that, in the video conference scenario, when determining the content forms included in the service layer of different data packets, the data packets without address information and port information of the video conference service end in the service layer may be directly forwarded to the video conference client without unpacking, so that the processing flow can be simplified to a certain extent.
In this way, by modifying the address information existing in the service layer in the data packet fed back by the video conference server, all the data packets sent by the video conference client can be received by the video conference acceleration platform and transmitted by means of the optimal transmission link, so that the transmission quality of the data packets and the effective implementation of the video conference are ensured.
