Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
First embodiment
An embodiment of the present invention provides a media resource management method for a cloud conference, as shown in fig. 1, the method includes:
step 101: and acquiring a first media capability supported by the terminal matched with the cloud server.
The embodiment of the invention is applied to a cloud conference system, wherein when a terminal needs to carry out a cloud conference, a media resource scheduling subsystem of the cloud conference system needs to search for a cloud server matched with the terminal. Specifically, a terminal needing to perform a cloud conference reports its own IP or call number or its located area to the cloud conference system, so that a media resource scheduling subsystem in the cloud conference system can search for a cloud server matched with the IP or call number of the terminal or its located area.
For example, as shown in fig. 2, where a is a media resource scheduling subsystem, B1 and B2 are both cloud servers of a first region, C1 and C2 are both cloud servers of a second region, D1, E1, F1, G1, and H1 are all terminals of the first region, and D2, E2, F2, G2, and H2 are all terminals of the second region. When any one of D1, E1, F1, G1 and H1 accesses the cloud conference system, a may configure the cloud server finding the first area according to rules such as IP matching, call number matching or area matching. When the call and the media resources of the cloud server in the first area are used up, the cloud server in the second area can be found to be accessed. Similarly, when any one of D2, E2, F2, G2 and H2 accesses the cloud conference system, a may configure the cloud server of the second area according to rules such as IP matching, call number matching or area matching for access, and when the calls and media resources of the cloud server of the second area are used up, may find the cloud server of the first area for access.
After the cloud server matched with the terminal is found, the terminal reports the first media capability supported by the terminal to the cloud conference system through interaction with the cloud conference system. Wherein the first media capabilities supported by the terminal include audio capabilities and video capabilities. Specifically, for example, the audio capabilities include G711 audio, G719 audio, AMR audio, and the video capabilities include H264 high definition, H264 standard definition, and H264 low definition.
Step 102: and acquiring a second media capability supported by the cloud server.
The cloud server in the cloud conference system also has media capabilities supported by itself. Here, in order to distinguish the media capabilities supported by the cloud server from the media capabilities supported by the terminal, the media capabilities supported by the cloud server are referred to as a second media capability. Like the first media capability, the second media capability also includes an audio capability and a video capability. Specifically, for example, the audio capabilities include G711 audio, G719 audio, AMR audio, and the video capabilities include H264 high definition, H264 standard definition, and H264 low definition.
Step 103: and determining the target media capability according to the first media capability and the second media capability.
When the terminal performs the cloud conference, only audio may be needed, video is not needed, or both audio and video may be needed, and the target media capability selected in step 103 may be the target audio capability, or the target video capability and the target audio capability.
When the first media capability comprises a first audio capability, the second media capability comprises a second audio capability, and the target media capability comprises a target audio capability, step 103 comprises:
obtaining a first intersection between the first audio capability and the second audio capability;
and selecting an audio capability from the first intersection as the target audio capability according to the output effect of the audio capability.
In the embodiment of the invention, an intersection is taken between a first audio capability supported by the terminal and a second audio capability supported by the cloud server, and then one audio capability with good output effect is selected from the intersection as a target audio capability required by the terminal for carrying out the cloud conference. Therefore, the requirements of the terminal side can be met, the configuration requirements of the cloud server can be met, and a good audio output effect is achieved.
In addition, when the terminal further needs videos during the cloud conference, the first media capability further comprises a first video capability, the second media capability further comprises a second video capability, and the target media capability further comprises a target video capability; correspondingly, after the step of selecting an audio capability from the first intersection as the target audio capability according to the output effect of the audio capability, the method further includes:
obtaining a second intersection between the first video capabilities and the second video capabilities;
and selecting a video capability from the second intersection as the target video capability according to the output effect of the video capability.
That is, if the terminal needs a video, the video capabilities supported by the terminal are reported to the cloud conference system, but in the embodiment of the present invention, an intersection is taken between a first video capability supported by the terminal and a second video capability supported by the cloud server, and then one video capability with a good output effect is selected from the intersection as a target video capability required by the terminal when the terminal performs the cloud conference. Therefore, the method can meet the requirements of the terminal side and the configuration requirements of the cloud server, and has a good video output effect.
Step 104: and distributing media resources for the target media capability according to the media resources required by the target media capability.
Preferably, step 104 comprises:
searching a first media resource required by the target audio capability and a second media resource required by the target video capability from a pre-stored media resource requirement table;
judging whether the total media resources of the cloud server obtained through pre-calculation are larger than or equal to the sum of the first media resources and the second media resources;
if the total media resource is greater than or equal to the sum of the first media resource and the second media resource, allocating the first media resource to the target audio capability and allocating the second media resource to the target video capability from the total media resources of the cloud server;
the media resources required by a plurality of audio capabilities and the media resources required by a plurality of video capabilities are recorded in the media resource requirement table.
In the cloud conference system, media resources required by each audio capability and media resources required by each video capability are pre-stored, so that after the target audio capability and the target video capability required by the terminal are determined through the steps, a first media resource required by the target audio capability and a second media resource required by the target video capability can be obtained through table lookup.
In addition, for the total media resources of the cloud server, when the cloud server is started, the total media resources can be obtained by the media resource scheduling subsystem according to the system performance and the audio reference value occupying the lowest energy consumption. Specifically, for example, if there are N Virtual Cores (VCPUs) on the cloud server, one virtual core can support 2000G 711 audios, or 1000G 719 audios, or 500 AMR, or 1H 264 high definition, or 2H 264 standard definition, or 4H 264 low definition, then the total media resource of the server is N × 2000, which is equivalent to that the cloud server has N × 2000 resource units available for the audio capability and the video capability. At this time, one channel of G711 audio needs to be allocated with one resource unit, one channel of G719 audio needs to be allocated with 2 resource units, one channel of AMR audio needs to be allocated with 4 resource units, one channel of H264 high definition video needs to be allocated with 2000 resource units, one channel of H264 standard definition video needs to be allocated with 1000 resource units, and one channel of H264 low definition video needs to be allocated with 500 resource units.
Therefore, different audio capabilities need different media resources, different video capabilities need different media resources, and the embodiment of the invention can allocate the media resources according to the finally selected target audio capability and the media resources actually needed by the target video capability, can fully utilize the hardware resources of the cloud conference system, and enables the allocation of the media resources to be optimal, thereby effectively solving the problem of overhigh operation cost caused by overhigh requirement on the hardware by the deployment of the cloud conference.
In addition, after the terminal accessed to the cloud server is accessed, namely, after the terminal is disconnected from the cloud server, the embodiment of the invention can also perform defragmentation of media resources, so as to ensure that the media resources are continuously distributed on the same VCPU as much as possible.
Specifically, if a first terminal is disconnected from a first virtual core of a cloud server, it is determined whether the first virtual core is fully loaded after the first terminal is disconnected from the first virtual core of the cloud server, and if the first virtual core is not fully loaded, a second terminal bound to a second virtual core of the cloud server is re-bound to the first virtual core until the first virtual core is fully loaded; the second virtual core is a virtual core in the cloud server except the first virtual core.
For example, as shown in fig. 3, four terminals LD1, LD2, LD3 and LD4 are fully accessed on VCPU1, and four terminals LD5, LD6, LD7 and LD8 are fully accessed on VCPU2, after the terminals LD4 and LD5 are down, the embodiment of the present invention will detect whether the currently used VCPU is not fully allocated, and if there is not, the threads on which the operations of decoding, scaling, synthesizing and encoding of the accessed media on other VCPUs are located will be re-bound to the non-fully loaded VCPU. Therefore, the media resources can be adjusted to the same VCPU as much as possible, the continuous allocation of the residual resources is ensured, and the terminal which requires higher resources can be accessed next time, such as: standard definition terminals or high definition terminals.
In summary, the embodiments of the present invention can not only allocate media resources according to the actual requirements of media capabilities, but also arrange fragmented resources after a meeting is performed under a terminal, so as to more fully utilize hardware resources of a cloud conference system.
