Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a system for scheduling devices.
Background
An Internet Protocol Television (IP Television) is a new technology that combines the features of a telecommunication network, a radio and Television network, and an Internet network, and can provide a variety of services including digital televisions to users. The user can enjoy the interactive network television service at home through terminal equipment such as a network set-top box.
In order to meet the service requirements of a large number of users, the IPTV system generally deploys service nodes in a layered and regional manner, and provides services for the users at edge nodes as much as possible, so as to reduce the load of the backbone network. Each service node comprises a plurality of media servers and storage equipment, wherein the storage equipment is used for storing media contents, and the media servers are used for performing read-write operation on the storage equipment. When the media server receives the request of playing media content from the user terminal, the media server reads the media data from the corresponding storage device and sends the media data to the user terminal, and the media data is decoded and played by the terminal device. Besides the media server and the storage device, the IPTV system also includes various management devices for implementing functions such as media content management, user request scheduling, authentication charging, value added service, etc.
In the IPTV system, the number of service nodes, the number of media servers, and the number of storage devices are configured by calculation according to the maximum number of concurrent users, the number of recorded channels, and the number of requested contents. For example, the IPTV system is required to support 3000T content storage for 100 ten thousand concurrent users, and a media server has a service capability of 1000 users, and a storage device has a capacity of 5T, so at least 1000 media servers and 600 storage devices are required, and if redundancy and backup are considered, the number of the storage devices is increased accordingly. However, according to the user access statistical data, in the actual using process, the user amount in most time does not reach the preset maximum concurrent user amount, and about 10% of the maximum concurrent number is only about half of the time. However, in the existing IPTV system, regardless of the number of actual users, all media servers and storage devices of the entire system are always in a running state, which results in a large amount of idle device resources, and causes unnecessary power consumption waste and device loss.
Disclosure of Invention
In order to solve the above technical problems, embodiments of the present invention provide a method, an apparatus, and a system for scheduling a device, so as to reduce idle device resources of an IPTV system, where the technical scheme is as follows:
the embodiment of the invention provides a device scheduling method, which comprises the following steps:
acquiring current user load information of an IPTV system;
and judging whether the current user load of the system is lower than a preset low load threshold value or not, and if so, adjusting part of equipment in the system to be in a standby state.
An embodiment of the present invention further provides an apparatus scheduling apparatus, including:
a user load obtaining unit, configured to obtain current user load information of the IPTV system;
and the equipment standby control unit is used for judging whether the current user load of the IPTV system is lower than a preset low load threshold value or not according to the current user load information of the IPTV system obtained by the user load obtaining unit, and if so, adjusting part of equipment in the system to be in a standby state.
The embodiment of the invention also provides a device scheduling system, which at least comprises the device scheduling device and at least one media server.
In the technical scheme of the embodiment of the invention, when the actual load of the IPTV system is small, a part of equipment is dynamically selected to enter the standby state, and at the moment, the equipment in the running state only provides service for a user, so that the power consumption waste and the loss of the equipment are effectively reduced under the condition that the actual service quality is not influenced.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
First, a device scheduling method provided by an embodiment of the present invention is explained, referring to fig. 1, including the following steps:
s101, obtaining the current user load of the IPTV system;
s102, judging whether the current user load is lower than a preset low load threshold value or not, and if so, adjusting part of equipment in the system to be in a standby state, wherein the equipment comprises a media server.
The executing body of the above steps may be a scheduling server in an IPTV system, and considering that the user volume in most of the time does not reach the preset maximum concurrent user number in the actual using process, the scheme provided by the embodiment of the present invention is applied to add an automatic matching function of the current system user load and the system capacity to the scheduling server, and control the number of devices capable of providing the IPTV service according to the current concurrent user volume, where the IPTV system includes a plurality of media servers. Therefore, under the condition of not influencing the service quality, the power consumption waste and the loss of the equipment are effectively reduced. The standby state in the embodiment of the present invention refers to that the device is in a sleep state, and the power consumption is only used to maintain the current interrupt information of the device, or the device is in a power-off state, but can be powered on and operated immediately after being activated.
During the device scheduling process, the scheduling server may be responsible for transferring user services on the device that is ready to enter the standby state to other devices that are in the active state. When the user terminal sends the service request again, the scheduling server selects the equipment in the running state to provide service for the user; that is, when the user terminal sends the service request again, the scheduling server transfers the service task originally processed by the device adjusted to the standby state to the device in the running state. When the user load of the system increases, the devices in the standby state can be activated, and after the devices in the standby state are activated originally, the scheduling server can also notify the content management server to update the content on the activated devices, so as to ensure that the content on the devices and other devices in the running state are synchronized.
The technical solution of the present invention will be further described in detail with reference to the specific application example of the IPTV system. Referring to fig. 2, the present embodiment includes the following steps:
s201, obtaining the current user load of the system.
In the IPTV system, each media server will report its own load condition, including the current number of concurrent users, concurrent bandwidth consumption, etc., to the scheduling server periodically. The scheduling server may count the total user load of each media server in the whole system in real time or periodically, where the user load may be measured by the number of concurrent users of the system, or the concurrent bandwidth consumption of the system.
S202, comparing the current user load with a preset low load threshold.
At least one low load threshold value is pre-configured on the scheduling server, and after the scheduling server obtains the current user load of the system, the current user load of the system is compared with the low load threshold value, namely, the sum of the current user loads of the media servers of the system is compared with the low load threshold value. If the current user load is lower than the preset low load threshold, the subsequent steps are further executed.
S203, parts of equipment in the system are adjusted to be in a standby state.
If the current user load of the system is lower than a preset low load threshold value, the scheduling server adjusts a part of the devices to be in a standby state. The adjustment object may include a media server, that is, a scheduling server adjusts a part of the media servers in the IPTV system to a standby state. The specific adjustment target is selected by the scheduling server, and the selected device is referred to as a standby device. The standby media server is prepared, i.e. the media server in the intermediate transition state between the running state and the standby state, and the standby media server does not process a new IPTV task, but needs to process the unprocessed service on the server. According to the difference between the networking mode of the actual IPTV system and the distribution mode of the media data, the standby preparation equipment can be selected in various modes: for example, according to a scheduled scheduling policy, the scheduled scheduling policy holds: devices that are not currently in service or that are currently under low load are selected as standby devices, media servers at edge nodes are selected, media servers at a central node are selected, or some devices may be randomly selected as standby devices.
And if the current user load of the IPTV system is not lower than the set low load threshold, not processing.
For the way of randomly selecting the standby device, the scheduling server needs to further check whether the determined standby device is currently in a service state, and if not, the standby device can be directly adjusted to the standby state. If the standby device is currently providing services for the user, that is, the standby device is currently in a service state, it is necessary to first migrate a service task on the standby device to another device, and then adjust the standby device to a standby state, where a target device for service task migration should be a device in an operating state, and the target device is neither a standby device nor a standby device, and the specific method for service task migration may include the following steps:
s203a, acquiring the current service content and service mode of the standby device;
assuming that the media server a is determined to be a standby device, the scheduling server queries the user connection information on the media server a to obtain information about what program the user is watching, the current playing mode, the time point of playing, and the like.
S203b, according to the current service content of the standby device media server A, selecting the corresponding media server in running state as the target device;
according to the program being watched by the user, the scheduling server selects one media server B in a running state as a target device to prepare to take over the service of the media server A.
S203c, notifying the target device that the media server B is responsible for the service task according to the current service mode of the standby device media server a.
The following description is made with the standby devices currently in different service modes, respectively:
1) preparing the current service mode of the standby device to provide a pause play mode for the user terminal:
if the current service mode of the standby preparation equipment is a pause playing mode provided for the user terminal, a media control channel is established with the target equipment, the pause time point is notified to the target equipment through the media control channel, and the target equipment is indicated to provide service for the user terminal from the pause time point when the user terminal selects to continue playing.
For example, if the standby device media server a is currently providing the pause playback mode, the scheduling server establishes a media control channel with the media server B, notifies the media server B of the currently played media content and the time point of currently providing the pause playback mode and pause through the established media control channel, and instructs the media server B to transmit a media stream to the user terminal from the pause time point when the user selects to continue playing, and then the scheduling server may disconnect the media control channel with the media server a. Thereafter, when the user selects "continue playing", the media stream will be continuously transmitted to the user by the media server B from the position of the pause time point.
2) Preparing the current service mode of the standby device to provide the user terminal with the playing mode:
if the current service mode of the standby preparation equipment is a mode for providing a user terminal with a playing mode, determining a switching time point in the current service content;
notifying the standby device of the switching time point and instructing the standby device to stop providing the service to the user terminal when the service reaches the switching time point,
and establishing a media control channel with the target equipment, informing the target equipment of the switching time point through the established media control channel, and informing the target equipment of providing services for the user terminal from the switching time point.
For example, the following steps are carried out: the standby device media server a is currently in the play mode for providing the user terminal with the on-air, in this case, in order not to affect the continuity of the service, the following scheme may be adopted:
a switching point in time is first determined by the scheduling server within the current media, which switching point in time is, as will be appreciated, located after the current play point in time. The scheduling server establishes a media control channel with the media server B first, and notifies the switching time point to the media server A of the standby device and the media server B of the target device respectively, wherein the purpose of notifying the media server A is to indicate that the media server A stops sending the media stream to the user terminal when playing to the switching time point, the scheduling server immediately notifies the media server B when knowing that the media server A stops sending the media stream, and the media server B continues to send the media stream to the user from the position of the switching time point. Thereafter, the scheduling server may disconnect the media control channel from media server a.
If the IPTV system supports media content segment storage and scheduling, the end time point of the current segment may also be directly used as the switching time point, and this way actually uses the segment change as the basis for service task migration, that is: after the media server A finishes playing the current fragment, the media server B continues to play the next fragment to the user.
In addition, the playing mode of the media may include a fast forward playing mode, a fast backward playing mode, and the like besides the normal speed playing mode, and the scheduling server may also notify the current playing mode of the media server a to the media server B, so as to ensure that the original playing mode is still maintained after the service task is migrated. Particularly, for the case that the change of the segment is taken as the basis for the migration of the service task, when the fast-rewinding operation of the user exceeds the left boundary of the current segment, the media server B should continue to provide the last segment of the current segment for the user.
After the scheduling server migrates all the service tasks on the media server a to the media server B, the scheduling server notifies the media server a to enter a standby state, and records that the current state of the media server a is the standby state.
And S204, sending the identifier of the equipment adjusted to the standby state to the media content management server.
After the media server a is adjusted to the standby state, the scheduling server sends the identifier of the media server a to the media content management server to notify the media content management server that the media server a has entered the standby state, and thereafter the media content management server will not issue or delete content to the media server a.
S205, receiving a media playing request sent by the user terminal.
S206, selecting the equipment for providing the service for the user.
When receiving a new media playing request, the scheduling server first filters out the media servers which are already in a standby state or ready for standby, and then further selects a proper media server to provide services for the user terminal according to the media content requested to be played by the user.
S207, the scheduling server forwards the media playing request of the user to the selected media server.
S208, the media player reads the media file data from the corresponding storage device.
S209, the media server sends a play response to the scheduling server.
S210, the dispatching server forwards the play response to the user terminal.
S211, the media server provides a service to the user terminal.
S212, comparing the current user load with a preset high load threshold.
At least one high load threshold is also preconfigured on the dispatch server. Since the scheduling server counts the total of the current user loads of the media services of the whole system in real time or periodically, after setting part of the devices in the standby state, the scheduling server also compares the current user load with a preset high load threshold value at any time, and if the current user load is higher than the preset high load threshold value, the subsequent steps are further executed.
S213, activating the device in the standby state.
I.e. readjusts the media server, which was previously adjusted to the standby state, to the running state.
S214, the activated equipment identification is sent to the content management server.
And sending the equipment identification of the media server readjusted to be in the running state to the media content management server.
For example, after the scheduling server readjusts the media server a that was previously adjusted to the standby state to the running state, the scheduling server sends the identifier of the media server a to the media content management server, and notifies the media content management server of the information that the media server a that was previously adjusted to the standby state was readjusted to the running state, and thereafter, the media content management server resumes the operations of releasing or deleting the content to the media server a.
S215, the content management server updates the media content in the activation device.
If the device readjusted to the running state misses the distribution of some on-demand content or the recording of a live program when being in the standby state, the content management server may query, according to the standby time and the sleep time of the device, which content the device misses, and notify the device to other devices with content to acquire corresponding content. Similarly, if some media content changes and deletions are missed during the standby of the device, the content management server may also notify the activated devices of the corresponding situation, thereby ensuring that the content on these devices is synchronized with the content of the device that is in an operational state.
The scheme controls the number of the devices capable of providing the IPTV service according to the current user load of the IPTV system, thereby effectively reducing the power consumption waste and the loss of the devices. It can be understood that, in the scheduling server, a plurality of low load thresholds may also be preset, so as to implement selecting different numbers of devices to enter a standby state according to different user load levels; accordingly, when the devices are activated, the scheduling server may activate all the devices in the standby state, or may activate only a part of the devices. The specific number of activations may be achieved by comparison with a plurality of preset high load thresholds.
In addition, the scheme also provides a method for migrating the service task of the equipment in the service mode, so that the equipment in the service mode enters a standby state under the condition of uninterrupted playing, and the service quality of a user is not influenced.
Those of ordinary skill in the art will understand that: all or part of the steps for implementing the method embodiments may be implemented by hardware related to program instructions, and the program may be stored in a computer readable storage medium, and when executed, the program performs the steps including the method embodiments; and the aforementioned storage medium includes: various media capable of storing program codes, such as ROM (Read-Only Memory), RAM (random access Memory), magnetic disk, and optical disk.
