Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. 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.
Currently, when CPE equipment under a CM plays a live program, a CMTS needs to forward a multicast data stream of the program to the CM playing the program, and since data is transmitted in multiple channels from DOCSIS3.0, transmission of one multicast stream in different channel sets needs to be duplicated. As shown in fig. 1, a CM1 is on a downlink channel 1 and a downlink channel 2, and a CM2 is on a downlink channel 3 and a downlink channel 4 in the conventional multicast configuration method. When the devices under CM1 and CM2, that is, CPE1 and CPE2, broadcast program a simultaneously, the CMTS is required to copy the program into two copies, one copy being placed on downstream channel 1 and downstream channel 2 and the other copy being placed on downstream channel 3 and downstream channel 4, so that CPE1 and CPE2 can receive the data of program a simultaneously.
Therefore, when the multicast is forwarded, the CMs need to be concentrated to the same channel as much as possible, and when the unicast data is forwarded, in order to improve the utilization rate of the channel and avoid the traffic exceeding the maximum capacity of a single channel, the CMs need to equalize the different channels, and in addition, the channels on the CM cannot be predicted (or cannot be dynamically changed according to the operation of switching programs by the user), so that the problem of multicast bandwidth replication cannot be avoided, and the utilization rate of the system bandwidth is low. The flow of the multicast group is scattered in a Media Access Control (MAC) domain of the CMTS, and is mixed with the traffic of the internet Service, which interferes with each other, affects the Quality of Service (QoS) of the direct Service, and finally affects the viewing experience of the user. Therefore, the prior art has the technical problems that the multicast service flow is duplicated in a plurality of channels and the utilization rate of the channel bandwidth is low.
Based on this, the multicast traffic configuration method, apparatus and system provided in the embodiments of the present invention can solve the technical problems that in the prior art, multicast traffic is duplicated in a plurality of channels, and the channel bandwidth utilization rate is low.
To facilitate understanding of the embodiment, a detailed description is first given of a multicast streaming method, an apparatus and a system disclosed in the embodiment of the present invention.
The first embodiment is as follows:
an embodiment of the present invention provides a multicast traffic configuration method, as shown in fig. 2, the method includes:
step S202, configuring a plurality of binding groups in a Cable Modem Termination System (CMTS), and setting channels for multicast into the binding groups, wherein the binding groups include: a multicast-specific binding group and a multicast-shared binding group.
Specifically, the multicast dedicated binding group is used for transmitting a multicast packet (live broadcast service); the multicast sharing binding group is used for transmitting multicast messages (live broadcast service) and unicast messages (internet access service), the binding group is divided into a multicast special binding group and a multicast sharing binding group, the utilization rate of a channel is improved, and the stability of the live broadcast service is ensured. In addition, the special multicast binding group separates multicast traffic from unicast traffic, and can achieve good balance effect and QoS effect; the multicast sharing binding group can enable the multicast flow and the unicast flow to share the channel bandwidth, and improve the channel utilization rate.
Step S204, a plurality of binding groups are set for the multicast group according to the audience rating of the multicast content, wherein the multicast group corresponds to the multicast content, and the multicast group corresponding to the target multicast content is a target multicast group.
It should be noted that the multicast content is a multicast program, the multicast group is a multicast message or a data frame, that is, a destination address of the multicast program transmission, and a binding group is set for the multicast group according to the audience rating of the multicast program. The target multicast content is a target multicast program, i.e. a multicast program to be watched by the user. If the multicast group can be matched with a plurality of binding groups, the multicast special group is preferentially selected for matching, and as the multicast special group is only used for bearing multicast flow, the multicast shared group is matched only after the load of the multicast special group reaches a threshold value.
Further, when new multicast content is added to a bonding group, the new multicast content is configured to the bonding group with the most remaining bandwidth. And if the multicast content is added into the binding group, stopping setting the new binding group. When a program which is not played by equipment is added into a binding group, balancing is carried out according to the residual bandwidth of the binding group, the multicast program is configured to the binding group with the largest residual bandwidth, and if the played program is added into the binding group, the previous binding group is used, so that the copying is avoided, and the resource configuration efficiency is improved.
Step S206, when the client CPE under the cable modem CM plays the target multicast content, the CM is triggered to send a request to the CMTS, where the request is used to join the target multicast group.
In addition, for the CM playing the multicast content, the load balancing of the unicast traffic is still performed, so that when the CPE under the CM does not play the multicast content, the channel of the CM is migrated to the channel of the unbound group and the channel of the multicast bound shared group, and the channel of the CM is migrated to the channel of the unbound group and the channel of the multicast bound shared group, where the traffic is the smallest. When the CPE under the CM plays the multicast content, keeping the CM channel position for the multicast content unchanged; when the CM channels for the unicast contents are load-balanced, the CM channels for the unicast contents are migrated to a channel having the smallest flow among the channels of the unbound group. The method ensures the stability of the multicast program and simultaneously performs load balancing, improves the utilization rate of the channel, and simplifies the complexity of a load balancing algorithm by separately and independently processing the unicast channel and the multicast channel.
Step S208, determining whether there is a multicast session of the target multicast content, if not, executing step S210, and if so, executing step S212.
And step S210, if not, selecting the binding group with the largest residual bandwidth from the binding groups according to the binding group corresponding to the target multicast group for binding, and establishing a multicast session corresponding to the target multicast content.
Step S212, add the CM to the multicast session.
In addition, before adding the CM into the multicast session, the method further includes: configuring a first threshold value and a second threshold value of a binding group, wherein the first threshold value is smaller than the second threshold value; when the binding group reaches a first threshold value, stopping adding the new multicast session to the binding group so as to prevent the multicast session from being interfered; and when the binding group reaches a second threshold value, migrating the session with the least CM in the multicast session corresponding to the binding group so as to realize active balance. The whole load of the binding group is controlled to be in a reasonable level through a threshold value, and the added programs are ensured not to be interfered.
Step S214, the channel of the CM is migrated to the channel corresponding to the bonding group of the multicast session, so that the channel of the CM receives the target multicast content traffic.
In addition, the ability of the CM must be satisfied when migrating the channel of the CM, and if the CM does not support the full band, the span between the multicast channel and the unicast channel will cause the CM to drop. Therefore, the number of receiving modules carried by the CM and the number of channels carried by each receiving module are identified by the attribute information in the receiving channel table RCP; segmenting a discontinuous channel set consisting of a multicast channel and a unicast channel to obtain a target channel set; the target channel set is arranged in the receiving module, so that the CM can be prevented from being disconnected.
Assume that there are 64 channels for CM: 1,2,3, 64, which correspond to channel frequencies in increasing order, it is sufficient to compare the channel ids directly. At present, the CM comprises at most two receiving modules, therefore, a discontinuity point with the largest difference between the channel IDs is found, and the CM channel set is divided into two receiving modules, namely, the maximum value of [ ChanId (k) -ChanId (k-1) ] is found, at this time, ChanId (k) is pivotChanId, channels smaller than pivotChanId are drawn into the first RM, channels larger than or equal to pivotChanId are drawn into the second RM, wherein, ChanId (k) is a pointer for pointing to the channel frequency band. Such as: channel set after a CM joins multicast (1-4 for multicast): 1,2,3,4, 31,32,35,36 ═ is segmented into: RM 1: 1,2,3, 4; RM2:31,32,35, 36.
Specifically, a schematic diagram of a CMTS channel plan is shown in fig. 3, in which four rectangular boxes on the left side represent 4 pre-planned bonding groups, including 2 multicast-specific bonding groups and 2 shared bonding groups, in which respective channel IDs and program lists allowed to be added are listed, the programs are divided into A, B levels from high to low according to the audience rating, and the rightmost rectangular box represents the remaining channels that can be used for planning other bonding groups or used as common channels. The figure comprises two groups of multicast special binding groups (a multicast special group-1 and a multicast special group-2) and two groups of multicast sharing binding groups (a sharing group-1 and a sharing group-2), wherein the channel ID (identification) corresponding to the multicast special group-1 is 1-3, the program A-1, the program A-2, the program A-3 and other multicast programs are relatively high in audience rating and relatively high in the on-demand degree of a user. The channel ID corresponding to the multicast special group-2 is 4-6, the program A-1, the program A-2, the program A-3 and other multicast programs. The channel ID corresponding to the shared group-1 is 7-9, the program B-1, the program B-2, the program B-3 and the unicast service (internet traffic), and compared with the programs in the multicast dedicated group-1 and the multicast dedicated group-2, the on-demand degree of the user is lower. The other bonding groups are non-bonding groups, channel ID: 13-64, and all the non-bonding groups are not listed one by one in the embodiment and are replaced by a dashed box. The specific implementation process is as follows:
the user turns on the television (CPE) to watch program a-1, triggering the CM (assuming the CM is already online on a 21-28 channel) to issue a join multicast group request to the CMTS; the CMTS checks whether a multicast session corresponding to the program A-1 exists or not, if the multicast session does not exist, the loads of a multicast special group-1 and a multicast special group-2 are checked according to the mapping relation between the program and the binding group, the binding group with the largest residual bandwidth (assumed to be the multicast special group-1) is selected for binding, and the multicast session corresponding to the program A-1 is established; after the CMTS completes the creation of the multicast session, the CM is informed of the channel of the multicast session and other relevant information and is migrated to the 1-3, 24-28 channels, so that the CM can normally receive the multicast traffic.
When the user changes the station to B-1, the CMTS also checks the mapping relation between the program and the binding group according to the request sent by the CM, according to the program planning in the graph, the CMTS compares the residual bandwidths of the sharing group-1 and the sharing group-2 in the graph, selects the binding group with the maximum residual bandwidth (assumed as the sharing group-1), and creates a new multicast session; the CMTS notifies the CM again after completing the creation of the new multicast session and migrates it to the 7-9, 24-28 channel, and the CM can receive the traffic for the new program as normal.
The above process describes the process of adding and switching to a session that does not exist, if the CM is added to the existing session, the process of searching the mapping relationship between the program and the binding group and selecting the binding group with the maximum residual bandwidth is omitted, the original binding group of the session is directly used to inform the CM of the related information, and the CM is enabled to migrate the channel.
The multicast configuration method provided by the embodiment of the invention can realize that a plurality of CMs share the channel corresponding to the same multicast group, thereby avoiding the bandwidth waste caused by multicast flow replication, and when the flow of a certain binding group overflows, a proper binding group can be selected to achieve load balancing.

identifying the number of receiving modules carried by the CM and the number of channels carried by each receiving module through attribute information in a receiving channel table (RCP);
segmenting a discontinuous channel set consisting of a multicast channel and a unicast channel to obtain a target channel set;
setting the target channel set in the receiving module.
3. The method of claim 1, wherein prior to the joining the CM into the multicast session, further comprising:
configuring a first threshold and a second threshold of the binding group, wherein the first threshold is smaller than the second threshold;
when the bonding group reaches the first threshold, stopping adding a new multicast session to the bonding group;
and when the binding group reaches the second threshold value, migrating the session with the least CM in the multicast session corresponding to the binding group.
4. The multicast traffic configuration method according to claim 1, further comprising:
and when the CPE under the CM does not play the multicast content, migrating the channel of the CM to a channel of a non-binding group and a channel with the minimum flow in the channels of the multicast sharing binding group.
5. The multicast traffic configuration method according to claim 1, further comprising:
when the CPE under the CM plays the multicast content, keeping the CM channel position for the multicast content unchanged;
when the CM channels for the unicast contents are load-balanced, the CM channels for the unicast contents are migrated to a channel having the smallest flow among the channels of the unbound group.
6. The multicast traffic configuration method according to claim 1, further comprising:
when new multicast content is added to the bonding group, the new multicast content is configured to the bonding group with the most remaining bandwidth.
7. The multicast traffic configuration method according to claim 1, further comprising:
and if the multicast content is added into the binding group, stopping setting a new binding group.
8. A multicast traffic configuration apparatus, comprising:
a configuration module configured to configure a plurality of bonding groups at a Cable Modem Termination System (CMTS) and set channels for multicast into the bonding groups, wherein the bonding groups include: a multicast dedicated binding group and a multicast shared binding group;
the setting module is used for setting a plurality of binding groups for the multicast group according to the audience rating of the multicast content, wherein the multicast group corresponds to the multicast content, and the multicast group corresponding to the target multicast content is a target multicast group;
a triggering module, configured to trigger a cable modem CM to send a request to a CMTS when a client device CPE under the CM plays the target multicast content, where the request is used to join the target multicast group;
the judging module is used for judging whether the multicast session of the target multicast content exists or not;
if not, selecting a binding group with the largest residual bandwidth from the binding groups according to the binding group corresponding to the target multicast group for binding, and establishing a multicast session corresponding to the target multicast content;
a joining module, configured to join the CM into the multicast session;
a receiving module, configured to migrate a channel of the CM to a channel corresponding to the bonding group of the multicast session, so that the channel of the CM receives the target multicast content traffic.
9. A computer-readable medium having non-volatile program code executable by a processor, wherein the program code causes the processor to perform the method of any of claims 1 to 7.
