Detailed Description
For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
At present, before streaming media transmission is performed between a client and a server, a plurality of Round Trip Time (RTT) are required to be consumed to finish preparation work, and the streaming media transmission time delay is seriously influenced. To this end, in some embodiments of the present application: identity verification information can be generated for the client and provided for the client, so that for the client, if the identity verification information exists locally, the identity verification information can be configured into communication signaling aiming at the server, and UDP connection is initiated to the server based on the communication signaling, and signaling interaction can be realized between the client and the server based on the UDP connection; in addition, the server side can also carry out identity verification on the client side based on the identity verification information, and multiplex the UDP connection to carry out streaming media transmission under the condition that the identity verification of the client side is successful. Accordingly, in the embodiment of the application, the signaling interaction and the media transmission can multiplex the same UDP connection, and under the condition that the identity verification information exists locally at the client, the signaling interaction, the identity verification and the streaming media transmission start can be realized only by one interaction (0 RTT) between the client and the server, so that the transmission delay of the streaming media can be effectively reduced on the premise of ensuring the transmission safety.
The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a streaming media transmission system according to an exemplary embodiment of the present application. As shown in fig. 1, the system includes: a client 10 and a server 20.
The streaming media transmission system provided in this embodiment can be applied to various scenes that need to be transmitted in streaming media, such as a live broadcast scene, a video call scene, etc., and the application scene is not limited in this embodiment. The physical implementation of the client 10 and the server 20 may be varied in different application scenarios. For example, in a cloud live scenario, the server 20 may be a cloud host, a cloud server, a virtual center, a CND node, and the like. Of course, this is merely exemplary, and server 20 may be a conventional server, and the embodiment is not limited thereto. The client 10 may be a terminal device such as a personal computer, a smart phone, a tablet computer, etc. In addition, in this embodiment, the network architecture of the transmission network where the client and the server are located is not limited, and the client and the server may be under the CDN architecture of the content delivery network, where in this case, the server may be a CDN node or the like; of course, it may be under a cloud computing network, a local area network, or any other network architecture.
Referring to fig. 1, for a client 10, a UDP connection is initiated to a server 20 in the event that a streaming media acquisition requirement may occur. Specifically, the client 10 may find whether the identity verification information exists locally, and if so, may configure the identity verification information into communication signaling for the server 20, and initiate a UDP connection to the server 20 based on the communication signaling. The identity verification information may at least include information such as the client IP, etc. capable of identifying the identity of the client 10, and may further include some configuration information agreed between the server 20 and the client 10, such as a media encryption suite, a key, etc. to better support the preparation of the client 10 and the server 20 before streaming media transmission. Of course, these are also merely examples, and other information may be included in the identity verification information of the present embodiment, which is not limited thereto.
For example, the client 10 may desire to watch a live broadcast, for which purpose the client 10 may initiate an SDP request (communication signaling) to the server 20 and may carry the identity verification information provided by the server 20 for it in the SDP request. In this embodiment, the underlying transport protocol may be UDP between the client 10 and the server 20, so that the client 10 may send the communication signaling to the server 20 in the form of a UDP packet. In addition to the identity verification information, network quintuples may be included in the communication signaling to identify the UDP connection between the client 10 and the server 20. In this way, after sending the communication signaling to the server 20, the client 10 automatically establishes a UDP connection, and the UDP connection may be identified by the network five-tuple. For the server 20, a signaling response may be returned to the client 10 under the UDP connection to complete the signaling interaction between the two parties. Correspondingly, the server 20 may also carry the network five-tuple corresponding to the UDP connection in the signaling response, so that the signaling response may be transmitted to the client 10 under the UDP connection. In addition, the server 20 may generate new identity verification information for the client 10, and carry the new identity verification information in the signaling response, so as to return the new identity verification information to the client 10, so that the client 10 updates the identity verification information locally, and uses the updated identity verification information in the next streaming media transmission process, which can ensure the activity of the identity verification information locally of the client 10, thereby ensuring the accuracy of the identity verification. Preferably, the server 20 may configure the identity verification information to a Ufrag field in the signaling response, where the Ufrag field is an existing field in the signaling response (e.g., SDP response), and the Ufrag field may include a random number, and in this embodiment, after the server 20 may write the identity verification information to the random number in the Ufrag field, the Ufrag field may be used as a carrier of the identity verification information to ensure that the identity verification information is not tampered with.
Accordingly, signaling interaction between the client 10 and the server 20 may be achieved based on the UDP connection.
Referring to fig. 1, the server 20 may further perform identity verification on the client 10 according to the identity verification information; if the identity verification of the client 10 is successful, the multiplexed UDP connection sends the streaming media to the client 10. As mentioned above, the identity verification information may include information such as the client IP for identifying the identity of the client 10, based on which the server 20 may compare the information for identifying the identity of the client in the identity verification information with the identity information actually provided by the client 10, for example, the client IP in the identity verification information may be compared with the actual IP of the client 10, and if the comparison is consistent, it may be determined that the identity verification of the client 10 is successful. The identity verification information cannot be tampered, so that the attacker can be effectively prevented from forging the identity information such as the client IP, the risk of attacks such as Drdos is avoided, and the security of streaming media transmission is ensured.
In this way, the server 20 can implement identity verification on the client 10 without adding additional interactions (i.e. without consuming RTT), thereby ensuring the security of streaming media transmission. After determining that the identity of the client 10 is verified successfully, the server 20 may multiplex the UDP connection to perform streaming media transmission, where the server 20 may also configure the network quintuple to ensure that the same UDP connection is used for interaction with the signaling. That is, the foregoing signaling interaction and the media transmission herein may multiplex the same UDP connection, and only 1 RTT is consumed between the client 10 and the server 20 to implement the signaling interaction, the identity verification, and start the streaming media transmission, which is equivalent to 0RTT for the streaming process, because the streaming itself occupies 1 necessary RTT.
In this embodiment, in the case that the identity verification of the client 10 is unsuccessful, the server 20 may signal to the client 10 that the media transmission request needs to be initiated in the signaling response, so as to further verify the identity of the client 10. The present embodiment is not limited to the exemplary manner herein, and for example, the signaling response may carry an identity verification failure notification, etc. In this way, the client 10 may determine whether a media transmission request needs to be initiated based on the signaling response.
In this case, the client 10 may initiate a media transfer request to the server 20 based on the signaling response while multiplexing the aforementioned UDP connection. For the server 20, when receiving the media transmission request sent by the client 10, it can be confirmed that the identity verification of the client 10 passes, because the signaling interaction and the media transmission request share the same UDP connection, and the client 10 initiates the media transmission request to indicate that the client 10 receives the signaling response returned by the server 20, so that it can be confirmed that the client 10 is not an attacker, and conversely, the attacker cannot obtain the signaling response returned by the server 20, and cannot forge the signaling response into the client 10 to initiate the media transmission request. Of course, since the server 20 already carries the identity verification information configured for the client 10 in the signaling response, the client 10 may carry the identity verification information in the media transmission request, so that the server 20 may use the above-mentioned comparison operation to perform identity verification on the client 10. In this way, the security of streaming media transmission can be ensured by adding one-time media-level interaction. Even if the interaction of the media layer is increased for 1 time, compared with the transmission delay of 5-7 RTT in the existing streaming media transmission scheme, the transmission delay of streaming media can still be effectively reduced in the embodiment.
In this embodiment, the local identity verification information of the client 10 may be from the server 20: as mentioned above, the server 20 may carry the identity verification information for the client 10 in the signaling response when the signaling response is returned to the client 10, so that the identity verification information on the back side of the client 10 may come from the historical UDP connection procedure between the client and the server 20. In this embodiment, the local identity verification information of the client 10 may also be from other servers equivalent to the server 20 in the cluster where the server 20 is located: the server in the cluster can provide an equivalent streaming media transmission service to the outside, so that the client 10 can use the identity verification information obtained in the process of performing historical UDP connection with other servers in the cluster, which are equivalent to the server 20, as a basis of identity verification in the process of performing UDP connection with the server 20. That is, in this embodiment, the identity verification information provided by the equivalent server in the same cluster to the client 10 is considered to be equivalent and reusable.
For example, the client 10 desires to obtain the streaming media of the live broadcast room a, and the equivalent server C and the equivalent server D in the cluster B can provide the streaming media of the live broadcast room a, so in this embodiment, the client 10 may dock to the server C or dock to the server B when the client initiates the streaming media of the live broadcast room a last time, and if docking to the server C, the server C may perform streaming media transmission based on the UDP connection with the client 10 and return the identity verification information to the client 10; the communication signaling initiated by the client 10 at this time may carry the identity verification information, and similarly, the communication signaling may be docked to the server C or the server B, if the communication signaling is docked to the server D, the server D may perform identity verification on the client 10 according to the identity verification information, and perform streaming media transmission based on UDP connection with the client 10 after the verification is successful. Thus, the two UDP connections can correspond to different service ends, and under the condition that the two service ends are equivalent, the identity verification information can be mutually recognized.
Accordingly, in this embodiment, UDP is designated as the underlying transport protocol, and the protocol of the application layer is improved, where the improvement concept includes: identity verification information can be generated for the client and provided for the client, so that for the client, if the identity verification information exists locally, the identity verification information can be configured into communication signaling aiming at the server, and UDP connection is initiated to the server based on the communication signaling, and signaling interaction can be realized between the client and the server based on the UDP connection; in addition, the server side can also carry out identity verification on the client side based on the identity verification information, and multiplex the UDP connection to carry out streaming media transmission under the condition that the identity verification of the client side is successful. Accordingly, in the embodiment of the application, the signaling interaction and the media transmission can multiplex the same UDP connection, and under the condition that the identity verification information exists locally at the client, the signaling interaction, the identity verification and the streaming media transmission start can be realized only by one interaction between the client and the server, so that the transmission delay of the streaming media can be effectively reduced on the premise of ensuring the transmission safety.
In the above or the following embodiments, the identity verification information may not exist locally in the client 10, for example, the client 10 may not have any history of communication between the servers 20, or the identity verification information local to the client 10 may have expired and been cleared, which may result in the absence of the identity verification information local to the client 10.
For this case, the client 10 may still initiate a UDP connection to the server 20. Here, however, the client 10 will initiate a UDP connection to the server 20 based on communication signaling that does not contain identity verification information. The server 20 may send a signaling response including the identity verification information to the client 10 under the UDP connection according to the signaling response scheme in the foregoing embodiment, so as to implement signaling interaction between the two parties under the UDP connection.
Since the communication signaling does not include the identity verification information of the client 10, the server 20 cannot verify the identity of the client 10 based on the communication signaling. In this case, the client 10 may initiate a media transmission request to the server 20 based on the signaling response under the UDP connection after receiving the signaling response including the identity verification information returned by the server 20 under the UDP connection. Wherein, the client 10 may actively initiate a media transmission request to the server 20; the server 20 may also indicate in the signaling response that the client 10 needs to initiate the media transmission request, and the client 10 re-initiates the media transmission request according to the indication, which is not limited in this embodiment.
The interaction procedure at the media level under this request corresponds to the aforementioned handling in case of failure of the identity verification of the client 10: for the server 20, when receiving the media transmission request sent by the client 10, it can be confirmed that the identity verification of the client 10 passes, because the signaling interaction and the media transmission request share the same UDP connection, and the client 10 initiates the media transmission request to indicate that the client 10 receives the signaling response returned by the server 20, so that it can be confirmed that the client 10 is not an attacker, and conversely, the attacker cannot obtain the signaling response returned by the server 20, and cannot forge the signaling response into the client 10 to initiate the media transmission request. Of course, since the server 20 already carries the identity verification information configured for the client 10 in the signaling response, the client 10 may carry the identity verification information in the media transmission request, so that the server 20 may use the above-mentioned comparison operation to perform identity verification on the client 10. In this way, the server 20 can implement identity verification on the client 10 based on the media transmission request, and multiplex the UDP connection to send the streaming media to the client 10 after the identity verification is successful.
Accordingly, in this embodiment, under the condition that the client does not have identity verification information locally, the client and the server can implement signaling interaction, identity verification and start streaming media transmission through two interactions (equivalent to a 1RTT scheme). In addition, the client has identity verification information locally through the current streaming media transmission process, so that in the subsequent streaming media transmission process, the client and the server can start streaming media transmission by only 1 interaction as described in the previous embodiment, thereby reducing transmission delay for the subsequent streaming media transmission process.
Fig. 2 is a logic diagram of an application scheme according to an exemplary embodiment of the present application. Referring to fig. 2, the application scheme presents processing logic in the case where the client does not have identity verification information locally. For example, the client accesses a live platform provided by the server for the first time.
Referring to fig. 2, the client may initiate an SDP request (communication signaling) to the server based on a UDP protocol, and may carry a C-ufrag (a conventional field in SDP, not described too much) of the client in a ice-ufrag of the SDP request, where the C-ufrag includes a random number random, so that a UDP connection is established between the client and the server. The server may then return an SDP response (signaling response) to the client, and carry the S-ufrag (the conventional field in SDP, not described too much) of the server in the ice-ufrag of the SDP response, where the S-ufrag may include a cookie (identity verification information) in addition to the conventional random number random, and the cookie may include at least the client_ip of the client.
So far, the signaling interaction between the client and the server is completed based on the UDP connection.
After that, the client may initiate a media transmission binding request to the server along the UDP connection, and carry the foregoing c-ufrag and s-ufrag in the media transmission request, and the server may perform identity verification on the client based on the c-ufrag and s-ufrag, and after the identity verification of the client is successful, the server may return a media transmission binding response to the client, and multiplex the UDP connection to transmit streaming media to the client (may use the RTP/RTCP protocol). Thus, the signaling interaction, the identity verification and the streaming media transmission can be completed through two interactions between the client and the server. Therefore, the first live streaming media transmission of the client and the server can be realized by only consuming very little RTT.
Fig. 3 is a logic diagram of another application scheme according to an exemplary embodiment of the present application. Referring to fig. 3, the application scheme presents processing logic in the case of the client having identity verification information locally present. For example, the client has used a live platform through the server yesterday, and during yesterday streaming, the server has provided identity verification information to the client. When the client uses the live platform again today, the streaming scheme may be implemented as processing logic of fig. 3.
Referring to fig. 3, the client may initiate an SDP request (communication signaling) to the server based on a UDP protocol, and may carry a C-ufrag (a conventional field in SDP, not described too much) and a cookie (local identity verification information) of the client in a ice-ufrag of the SDP request, so that a UDP connection is established between the client and the server. The server may then return an SDP response (signaling response) to the client, and carry the S-ufrag (the conventional field in SDP, not described too much) of the server in the ice-ufrag of the SDP response, where the S-ufrag may include a cookie (new identity verification information) in addition to the conventional random number random, and the cookie may include at least the client_ip of the client.
So far, the signaling interaction between the client and the server is completed based on the UDP connection.
Referring to fig. 3, the server may then verify the identity of the client based on the cookie, and if the identity of the client is verified successfully, the server may directly multiplex the UDP connection to transmit streaming media to the client (RTP/RTCP protocol may be employed). The signaling interaction, the identity verification and the streaming media transmission can be completed through 1 interaction between the client and the server.
If the identity verification of the client fails, the client may initiate a binding request to the server under the condition that the client does not receive the streaming media for a period of time or knows in the signaling response that the server needs to initiate an event such as a media transmission binding request, and the c-ufrag and s-ufrag are carried in the binding request. The server can then verify the identity of the client based on c-ufrag and s-ufrag, and after the identity of the client is verified successfully, the server can return a media transmission binding response to the client and multiplex the UDP connection to transmit streaming media to the client (RTP/RTCP protocol may be used). In this way, in the case that the identity verification of the client fails, the processing manner of the two interactions in fig. 2 can be adopted, and the signaling interaction, the identity verification and the streaming media transmission can be completed through the two interactions between the client and the service end.
