In the process of performing the video conference, the video conference can be performed based on the h.323 multimedia communication protocol, and can also be applied to video conference scenes under different communication protocols according to actual needs, which is not described herein again.
In the embodiment of the present disclosure, referring to fig. 1, which is a schematic view of interaction among nodes of a video conference client, a video conference server, and a video conference acceleration platform in the embodiment of the present disclosure, an interacting 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 composed of nodes deployed in various areas.
The video conference client in the present disclosure refers to a terminal application installed on a terminal device of a user and capable of performing video interaction, or a web service accessed through a terminal device browser, where the terminal device may be various electronic devices, such as a mobile terminal, a fixed terminal, or a portable terminal, specifically, a mobile phone, a desktop computer, a notebook computer, a tablet computer, and the like. The user can request to create the video conference through the video conference client, so that a video conference session is started, and when the video conference is finished with service, the video conference session is synchronously finished.
The video conference server in the present disclosure refers to a background management service application capable of providing services for a video conference, and may be deployed on an independent physical server or a server cluster, and the video conference server is a generic name of various background management services.
It is understood that the architecture of the video conference client and the video conference server in the present disclosure is only an example, and the present disclosure is not limited thereto, and the specific architecture is determined by the video conference service provider, and may be different from each other.
The video conference acceleration platform comprises nodes distributed in each Area, wherein each node can comprise one or more servers, and the nodes can be mutually communicated and connected to build a Network topology as required, so that the video conference acceleration platform can also be called a video conference acceleration Network and can provide Network services such as data acceleration, data security and the like for customers, and in some implementations, the video conference acceleration platform can be a CDN (content Delivery Network) Network or a Network built based on SD-WAN (secure-Wide Area Network) technology. The nodes of the video conference acceleration platform can be mutually detected to obtain the link quality between every two nodes, and then an optimal transmission link for transmitting a data packet between a video conference client and a 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 are described in further detail below with reference to the accompanying drawings:
referring to fig. 2, which is a schematic flow chart of a video conference acceleration method provided in an embodiment of the present disclosure, the method is described below with reference to fig. 2:
step 201: receiving a data packet sent by a video conference client at a local first session receiving address, determining an accessed video conference server according to the stored association relationship 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 at which the access node receives a data packet sent by the video conference client, where in a video conference session, the video conference client may send a plurality of data packets, and the content included in each data packet is different, for example, the content carried in the data packet may be: 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 general term of each address of the data packet received by the access node, and there may be a difference in address information corresponding to the first session receiving address specifically for different data packets.
In order to enable a first session data packet sent by a video conference client in a session to be successfully accessed to a video conference acceleration platform, in the embodiment of the present disclosure, each node in the video conference acceleration platform is preconfigured with a local fixed IP (Internet Protocol) address and a local port for receiving the first session sent by the video conference client, and an association relationship between the fixed IP address and the local port and a video conference server for processing the first session data packet, that is, each node is preconfigured with and stores a local fixed IP and a local port, and an association relationship between the local fixed IP and the local fixed IP port and the video conference server capable of processing the session data packet, wherein the fixed IP address and the local port on each node are different from each other because the fixed IP address and the local port are local addresses of each node, and the video conference server for processing the first session data packet on the same video conference server is a video conference server for processing the first session data packet The fixed IP address and the association between the port and the address of the video conference server are established by acquiring the address of the video conference server processing the first session data packet from the video conference service provider in advance.
In the actual video conference process, each node is configured with a first session receiving address, namely a local fixed IP address and a port, for receiving a first session of a video conference client, and video conference server information associated with the local fixed IP address and the port, so that no matter to which node a first session data packet of the video conference client is sent, it can be ensured that the data packet of the session is effectively transmitted to the corresponding video conference server.
In addition, DNS (domain Name system) information between each fixed IP address and a domain Name of a video conference service needs to be configured in advance to implement scheduling of a first session initiated by a video conference client 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, a DNS resolution request needs to be sent to obtain a destination IP address of the data packet of the first session, the video conference acceleration platform can intercept the DNS resolution request first, and determine a node receiving the first session of the video conference client as an access node in the video conference at this time by comprehensively considering a location of the video conference client and a load condition of each current node, where the access node may be a node which is closest to the video conference client and has processing capability, and the fixed IP address pre-configured on the access node is returned to the video conference client as a DNS analysis result, so that the first session sent by the video conference client can be received by the allocated access node, and the video conference client can be accessed to the video conference acceleration platform.
After the access node determines, from the local record and according to the first session receiving address, the video conference server that the data packet of the first conference really accesses, the access node acquires, from the video conference acceleration platform, a transmission link that reaches the video conference server, and the following describes a process of determining the transmission link:
the method for the access node to acquire the transmission link comprises two modes: first, a transmission link is actively created by an access node; and secondly, creating a transmission link by a management node in the video conference acceleration platform and issuing the transmission link to the access node, wherein the management node can issue the transmission link to the access node when receiving a link issuing request of the access node.
Specifically, the process of creating the transmission link may include constructing a preset number of candidate transmission links from the access node to the video conference server according to each node included in the video conference acceleration platform, and screening out 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, the link quality between the nodes may be determined by probing each other among the nodes of the platform, and based on this, the link quality of each candidate transmission link may be obtained according to the link quality between the nodes included in the candidate transmission links, so as to select at least one candidate transmission link that meets a preset condition as the transmission link, where the preset condition may be a determined threshold requirement, such as a delay requirement, a packet loss rate requirement, or a standard that is reached after calculating by synthesizing various quality parameters, or may be selected preferentially, such as selecting one or more strips with the best quality, etc., and the disclosure is not limited thereto.
It should be noted that the access node may acquire multiple transmission links, for example, two transmission links may be acquired at the same time for transmitting a data packet, and specifically, the active/standby policy may be adopted to use the links, or the transmission may be performed based on multiple links at the same time, 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 video conference 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 an effective transmission link aiming at the video conference server side is cached locally, determining whether a corresponding transmission link is selected for the current video conference session, and if so, determining that the effective transmission link is cached.
Step 202: and forwarding the data packet to the video conference server through the transmission link.
The access node of the video conference acceleration platform acquires the transmission link of the data packet and sends the data packet to the video conference server through the transmission link, and the transmission link is provided by the video conference acceleration platform, so that corresponding network services such as security guarantee, stability, speed and the like can be provided for the data packet in the transmission process.
It can be understood that, after receiving the data packet through the transmission link, the video conference server forwards the data packet fed back by the video conference server for the data packet through the transmission link to reach the access node, so that it is synchronously realized that the data packet sent by the video conference server in one session is also provided with a network service by the video conference acceleration platform.
Step 203: receiving a feedback data packet sent by a video conference server, modifying a 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 the 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 a 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 destination address, where the destination address is a service data part carried in a data packet message and is not quintuple information of a message header, and the destination address is a new destination address used by the video conference server to initiate a next session interaction after the video conference server indicates that the video conference client receives the feedback data packet.
And when the feedback data packet is determined to carry the target address, establishing and managing an incidence relation between the target address and a local second session receiving address. Specifically, the access node may locally select a free dynamic IP address and port or newly create a local dynamic IP address and port, as a second session receiving address, and establish and store an association relationship between the dynamic IP address and port and the target 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 target address is invalid, it should be noted that the fixed IP address and the dynamic IP address in this disclosure are both local IP addresses of the access node, and the fixed and dynamic IP addresses are only used for distinguishing whether the IP address is preconfigured or temporarily created in the session, so the dynamic IP address and port are different from the above-mentioned fixed IP address and port, and are temporarily assigned according to the session and are released.
That is to say, in the embodiment of the present disclosure, a fixed IP address and port and a dynamic IP address and port are relative concepts, the fixed means that the established association relationship does not end with the session, and the dynamic means that the association relationship with the target address ends with the end of the session, that is, the dynamic IP address and port are only used for distinguishing the corresponding target address in the process of the video conference, that is, the video conference server to which the transmission is required. Therefore, the dynamic IP address and port can be randomly allocated, as long as the IP address and port are not occupied by other sessions, and thus, the persistent storage is not necessary.
In the embodiment of the present 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 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 is invalid, where the manner of determining that the target address is invalid may be any of the following manners:
a1, determining that the session between the client and the video conference is closed.
Specifically, when the user operates to close the video conference on the video conference client, the association relationship between each dynamic IP address and port established on the access node for the session and the corresponding target address is deleted in response to the closing operation of the video conference.
A2, determining that the session with the video conference server is closed.
Specifically, when the video conference client performs an operation to close the video conference on another video conference client interacting with the video conference client, the association relationship between each dynamic IP address and port established on the access node for the session and the corresponding target address is deleted in response to the operation to close the video conference.
A3, determining that the waiting time for the video conference client to send the data packet reaches a set first time threshold.
Specifically, after the video conference acceleration platform determines that the time length for waiting for the video conference client to send the data packet reaches the first time length threshold, the video conference acceleration platform can automatically consider that the current session is ended, and delete the association relation between each dynamic IP address and port established on the access node for the session and the corresponding target address.
A4, determining that the waiting time for the video conference server to send the data packet reaches a set second time threshold.
Specifically, after the video conference acceleration platform determines that the time length for waiting for the video conference server to send the data packet reaches the second time length threshold, the video conference acceleration platform may automatically consider that the current session is ended, and delete the association relationship between each dynamic IP address and port established on the access node for the session and the corresponding target address.
In this way, after the target address is invalid, the generated dynamic IP address and the port are released, so that the address information can be used again, and address resources are saved.
Step 201 and step 203 disclose a process of processing 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 may exist between the video conference client and the video conference server, and the access node can process each data interaction based on the method, so that all data packets generated in one video conference session can be transmitted through a transmission link provided by the video conference acceleration platform, thereby providing a whole network service for the video conference, such as acceleration, security and other services.
Based on the video conference acceleration method disclosed by the embodiment, all data packets interacted between the video conference client and the video conference server in one video conference session can be transmitted by the 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 illustrated below with reference to an example.
Refer to fig. 3, which is a schematic diagram of data interaction in a video conference in an embodiment of the present disclosure.
S301: the videoconference client sends an RRQ message.
Specifically, in the process of the h.323 protocol-based video conference, the video conference client registers to the video conference server through a 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 is an address on a certain node (access node) in the video conference acceleration platform through DNS scheduling, so that the video conference acceleration platform can receive the RRQ message.
Step S302: and the video conference acceleration platform sends the RRQ message to a video conference server.
Specifically, the access node of the video conference acceleration platform may determine the video conference server S0 associated with the IP0: Port0 according to the fixed IP and Port (e.g., IP0: Port0) of the received data packet and the association relationship configured in advance locally, and further plan the optimal transmission link from the access node to 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 sends the RCF message fed back to the video conference acceleration platform.
Specifically, after receiving the RRQ message from the optimal transmission link, the video conference server S0 responds with a feedback Registration confirmation message (RCF), which is transmitted to the access node based on the optimal transmission link, where the RCF message includes a destination address of the video conference server S1 (e.g., SIP1: SPort1) accessed by the next session.
Step 304: and 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 destination address carried in the RCF message into a local receiving address (e.g. IP1: Port1) different from IP0: Port0, and establishes and stores the association relation between IP1: Port1 and SIP1: SPort 1.
Step 305: and the video conference acceleration platform sends the modified RCF message to a video conference client.
Specifically, the access node forwards the modified RCF to the video conference client.
Step 306: and the video conference client sends the call information such as Setup to the video conference acceleration platform.
Specifically, after receiving the modified RCF message, the video conference client may send a call message such as Setup for establishing a call to a destination address IP1: Port1 in the RCF message according to the indication of the RCF message, so that the access node may receive the call message such as Setup from IP1: Port1, based on which 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 to the video conference server.
Specifically, after receiving the call message such as Setup sent by the video conference client from the IP1: Port1, the access node determines the destination address associated with the IP1: Port1, that is, the SIP1: SPort1, from the association relationship stored locally, and sends the received data packet containing the call message such as Setup to the video conference server S1 pointed by the SIP1: SPort1 via the previously planned optimal transmission link.
Step 308: and the video conference server sends the call response message to the video conference acceleration platform.
The videoconference server S1 may reply to the received call message, and send call reply information, which is also transmitted based on the optimal transmission link, to reach the access node, where the call reply message may specifically be: the Call is handling Call precedence, Alerting, connecting Connect, etc., and carries an IP address and port of the videoconference server S2, e.g., SIP2: SPort2, for h.245 negotiation in the Call answer message.
Step 309: and the video conference acceleration platform modifies the IP address and the port contained in the call response message into a second session receiving address regenerated locally.
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, such as IP2: Port2, and establishes and stores the association relationship between IP2: Port2 and SIP2: SPort 2. Meanwhile, the SIP2: SPort2 carried in the call answer message is modified to IP2: Port 2.
Step 310: and 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 response message to the video conference client.
Step 311: the videoconference client sends an h.245 message to the videoconference acceleration platform.
Specifically, the videoconference client can send h.245 messages to IP2: Port2 for capability negotiation, master-slave decision making, and media channel establishment based on the received call answer message.
Step 312: and the video conference acceleration platform sends the H.245 message to the video conference server.
Specifically, after the access node of the video conference server receives the h.245 message from the IP2: Port2, based on the association relationship stored locally, the IP address and Port of the video conference server S2 used for h.245 negotiation can be determined, i.e., SIP2: SPort 2. And transmitting the H.245 message to a video conference server corresponding to the SIP2: SPort2 through the determined optimal transmission link.
Step 313: and the video conference server sends an H.245 response message to the video conference acceleration platform.
Specifically, after receiving an h.245 message, the video conference server generates an h.245 response message, where the h.245 response message includes messages such as Open Logical Channel (OLC) and Open Logical Channel Acknowledgement (OLCA), and further sends the h.245 response message carrying an IP address and a port (e.g., SIP3: SPort3) of the media Channel to the access node via the optimal transmission link.
Step 314: and the video conference acceleration platform modifies the IP address and the port of the media channel carried in the H.245 response message into a second session receiving address regenerated locally.
Similarly, after the access node receives the H.245 response message, a new receiving address different from the receiving address is created, such as IP3: Port3, and the association relationship between IP3: Port3 and SIP3: SPort3 is established and stored. Meanwhile, SIP3: SPort3 in the H.245 response message is modified to IP3: Port 3.
Step 315: and 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, thereby completing the early negotiation step of the video conference, and entering into a normal video conference.
Further, during the video conference, the video conference client accesses a 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, and then an 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 an optimal transmission link, and simultaneously reversely sends the media data packets fed back by the SIP3: SPort3 of the video conference server to the video conference client according to an original path until the video conference is finished.
It should be noted that, in a video conference scenario, when determining content forms included in service layers of different data packets, a data packet for which address information and port information of a video conference server do not exist in a service layer may be directly forwarded to a video conference client without unpacking, so that a processing flow may be simplified to a certain extent.
