Hereinafter, each step involved in the home multicast implementation method according to the exemplary embodiment of the present disclosure is explained and explained in detail.
First, a home multicast implementation system related to the exemplary embodiment of the present disclosure is explained and explained. Referring to fig. 3, the home multicast implementation system may include a terminal device 310, a home gateway 320, and an operator network 330. The terminal device 310 may be a mobile phone, a computer, or a television set-top box, and may send a multicast request message to the home gateway according to its own capability; the data message which is forwarded by the home gateway and corresponds to the multicast request message can be received; a home gateway 320, which is connected to the terminal device 310 through a network, and configured to receive a multicast request message sent by the terminal device, perform unified management on the received multicast request message, generate a multicast information table, generate a multicast application according to a multicast source address and a multicast group address included in the multicast information table, and send the multicast application to an operator network 330; the data message sent by the operator network 330 may also be received, and the received data message is sent to the terminal device 310; the operator network 330 is connected to the home gateway 320, and includes multiple routing devices, which are configured to receive a multicast request sent by the home gateway and send a corresponding multicast data packet to the home gateway 320 according to the multicast request.
Hereinafter, steps S210 to S230 will be explained and explained in detail with reference to fig. 3.
In step S210, a multicast request message sent by the terminal device is received, and a multicast information table is established according to the received multicast request message.
The terminal device may be a desktop computer, a portable computer, a smart phone, a tablet computer, a television set-top box, and the like, and the terminal device is not particularly limited in this example embodiment. The home gateway is a device for realizing mutual communication between each device in a home or a small area and an external device, and is the most core component in a home network.
In this exemplary embodiment, the receiving multicast request information sent by the terminal device includes:
and receiving an internet group management protocol/multicast interception discovery protocol (IGMP)/MLD multicast request message sent by the terminal equipment based on the attribute of the terminal equipment or receiving an IGMP multicast request message sent by the terminal equipment.
Specifically, when the terminal device has a request for a Multicast service, the terminal device sends a Multicast request message to the home gateway device, and when the terminal device sends the Multicast request message, the terminal device may send an IGMP (Internet Group Management Protocol)/MLD (Multicast Listener discovery Protocol) Multicast request message or an IGMP Multicast request message to the home gateway device according to the request, where the IGMP/MLD Multicast request message is a request message for applying for a Multicast Group, and the IGMP Multicast request message is a request message for leaving the previously applied Multicast Group.
In this exemplary embodiment, referring to fig. 4, when the received multicast request message is an IGMP/MLD multicast request message, establishing a multicast information table according to the received multicast request message may include steps S410 to S430:
step S410, acquiring a multicast source address and a multicast group address included in the IGMP/MLD multicast request message;
step S420, obtaining the IP address of the terminal equipment, and generating a multicast request record according to the IP address, the multicast source address and the multicast group address included in the GMP/MLD multicast request message;
and step S430, establishing a multicast information table through the multicast request record.
Hereinafter, steps S410 to S430 will be further explained and explained. Specifically, when the message sent by the terminal device is an IGMP/MLD multicast request message, after receiving the IGMP/MLD multicast request message, the home gateway first obtains a multicast source address applied for use by the device terminal and a multicast group applied for joining by the terminal device, which are included in the multicast request message. Then, in order to maintain each multicast request record, a terminal device address needs to be acquired, and since the terminal address of the terminal device may change each time the terminal device accesses the home gateway, the record may be performed through the IP address of the terminal device, that is, the IP (Internet Protocol) address of the terminal device is acquired, and a multicast request record is generated according to the IP address of the terminal device, the multicast source address applied for use by the terminal device, and the multicast group address applied for joining by the terminal device; and finally, establishing a multicast information table through the multicast request record.
In this exemplary embodiment, the home gateway serves as a proxy to provide a proxy service of a multicast request message for downstream end devices, performs unified management on the received multicast request message, writes the multicast request message of an end device into a multicast information table, maintains a multicast request record for each end device based on an IP address, and does not perform multicast routing service of the multicast request message as a basis for forwarding multicast data. In addition, by the maintenance mode based on the IP address of the terminal device, the terminal device is not limited to the access of a physical LAN (Local Area Network) port, and can be accessed through WIFI, and the multicast application range based on an operator Network is expanded.
In step S220, a multicast application is sent to an operator according to the multicast information table, and a data packet sent by the operator and corresponding to the multicast application is received.
In this exemplary embodiment, after the home gateway establishes the multicast information table, the multicast application may be sent to the operator based on the multicast information table, and as shown in fig. 5, sending the multicast application to the operator according to the multicast information table may include steps S510 to S530:
step S510, acquiring a multicast source address and a multicast group address in the IGMP/MLD multicast request information, and matching the multicast source address and the multicast group address with the multicast information table;
step S520, when the multicast information table is determined to comprise the multicast source address and the multicast group address in the IGMP/MLD multicast request information, filtering the IGMP/MLD multicast request information;
step S530, when it is determined that the multicast information table does not include the multicast source address and the multicast group address in the IGMP/MLD multicast request information, generating a multicast application through the multicast source address and the multicast group address, and sending the multicast application to the edge router of the operator.
Hereinafter, steps S510 to S530 will be further explained and explained. Specifically, when a multicast application is sent to an operator, first, a multicast source address and a multicast group address applied by a terminal device in IGMP/MLD multicast request information are obtained, the multicast source address and the multicast group address are matched in a multicast information table, and when it is determined that the multicast source address and the multicast group address applied by the terminal device are included in the multicast application table, the IGMP/MLD multicast request information is filtered, that is, the multicast request is not sent to an edge router of the operator, thereby avoiding repeated sending of multicast requests to the edge router of the operator and reducing network pressure. When determining that the multicast information table does not include the multicast group address and the multicast source address applied by the terminal device included in the IGMP/MLD multicast request information, recording the IGMP/MLD multicast request information, sending the multicast source address and the multicast group address included in the IGMP/MLD multicast request information to an edge router of an operator, and applying for a data packet from the multicast source to the edge router of the operator.
For example, when the multicast information table includes multicast request information numbered 1-3, when receiving the multicast source address included in the new IGMP/MLD multicast request information is 102.102.102.102 and the multicast group address is 232.0.0.2, since the multicast source address is 102.102.102.102 and the multicast address is 232.0.0.2 in the multicast request information numbered 3 in the multicast information table, the new IGMP/MLD multicast request information may be filtered out, and the multicast application is not sent to the edge router of the operator, and the home gateway may directly forward the data packet of the multicast source sent by the edge router of the operator corresponding to the number 3 to the terminal device sending the new IGMP/MLD multicast request information. It should be added that the home gateway sends the multicast source address and the multicast group address numbered 1, 2, and 3 to the edge router of the operator.
In this exemplary embodiment, referring to fig. 6, when the received multicast request message is an IGMP multicast request message, sending a multicast application to an operator according to the multicast information, which may further include step S610 to step S630:
step S610, acquiring a multicast source address and a multicast group address in the IGMP multicast request information, and matching the multicast source address and the multicast group address with the multicast information table;
step S620, when the multicast information table is determined to comprise the multicast source address and the multicast group address in the IGMP multicast request information, deleting the multicast request record corresponding to the IGMP multicast request information of the equipment terminal in the multicast information table;
step S630, when it is determined that the multicast information table does not include the multicast source address and the multicast group address in the IGMP multicast request information, a multicast application is generated through the multicast source address and the multicast group address, and the multicast application is sent to the edge router of the operator.
Hereinafter, steps S610 to S630 will be further explained and explained. Specifically, when the multicast request information sent by the terminal device is IGMP multicast request information, and after the home gateway receives the IGMP multicast request information, first, a multicast source address and a multicast group address included in the IGMP multicast request information are obtained, and the multicast source address and the multicast group address included in the IGMP multicast request information are matched in a multicast information table, and when it is determined that the multicast source address and the multicast group address in the IGMP multicast request information are included in the multicast information table, the home gateway deletes a multicast request record corresponding to the IGMP multicast request information of the terminal device in the multicast information table, that is, deletes a multicast request record including an IP address of the terminal device sending the IGMP multicast request information, and a multicast source address and a multicast group address in the IGMP multicast request information in the multicast information table; when the multicast information table does not include the multicast source address and the multicast group address included in the IGMP multicast request information, the home gateway sends a multicast application to the edge router of the operator according to the multicast source address and the multicast group address applied by the terminal device. It should be noted that, when the multicast information table does not include the multicast source address and the multicast group address included in the IGMP multicast request message, the home gateway does not store the IGMP multicast request message in the multicast information table after generating the multicast application according to the multicast source address and the multicast group address included in the IGMP multicast request message.
After the home gateway sends the multicast application to the operator, the operator may send a corresponding data packet to the home gateway according to the multicast application of the home gateway, and in this example embodiment, receiving the data packet sent by the operator and corresponding to the multicast application includes:
and receiving a data message which is sent by the edge router of the operator in a unicast mode and corresponds to the multicast application.
Specifically, after the home gateway sends the multicast application to the edge router of the operator, the edge router of the operator sends the data packet corresponding to the multicast source address in the multicast application to the home gateway according to the received multicast application. The edge router of the operator adopts a unicast mode when sending the data message to the home gateway.
In step S230, the data packet is sent to the corresponding terminal device through the multicast information table, so as to implement home multicast.
In this exemplary embodiment, after the home gateway receives the data packet sent by the edge router of the operator, the home gateway needs to forward the received data packet to the interrupt device, and referring to fig. 7, sending the data packet to the corresponding terminal device through the multicast information table may include step S710 and step S720:
step S710, obtaining a source address of the data message, and matching the source address with the multicast information table;
and S720, when the source address of the data message is consistent with the multicast source address in the multicast information table, sending the data message to the corresponding terminal equipment.
Hereinafter, step S710 and step S720 will be further explained and explained. Specifically, first, after receiving a data packet sent by an edge router of an operator, a home gateway obtains a source address of the data packet according to the received data; and then, matching the source address of the data message in the multicast information table, and sending the data message to the terminal equipment corresponding to the multicast source address when a multicast source address in the multicast information table is the same as the multicast source address of the data message. The source address of the data message is the address of a multicast source which sends the data message to the home gateway in the operator network.
In this exemplary embodiment, referring to fig. 8, when the source address of the data packet is consistent with the multicast source address in the multicast information table, sending the packet data to the corresponding terminal device may include step S810, step S820:
step S810, when the multicast information table comprises a plurality of multicast source addresses consistent with the source address of the data message, copying the data message according to the quantity of multicast source data consistent with the source address of the data message to obtain a plurality of data messages;
and S820, respectively sending the data messages to corresponding terminal equipment.
Hereinafter, the steps S810 and S820 will be further explained and explained. Specifically, first, when the home gateway matches the multicast information table by using the source address of the data packet and finds that a plurality of multicast source addresses in the multicast information table are the same as the source address of the data packet, the number of multicast source addresses included in the multicast information table and identical to the source address of the data packet is determined, the home gateway copies the received data messages according to the quantity, obtains a plurality of data messages after the copying is finished, sends each data message to the corresponding terminal equipment in a unicast sending mode,
the home multicast implementation method provided by the disclosed exemplary embodiment has at least the following advantages: on one hand, the home gateway proxies the multicast request message for different terminal devices, performs centralized management on the multicast request message through the multicast information table, and sends the multicast application to the operator according to the multicast information table, thereby avoiding sending repeated multicast application to the operator and reducing network pressure; on the other hand, after the home gateway sends the multicast application to the operator, the operator sends a corresponding data message to the home, and after the home gateway receives the data message sent by the operator, the home gateway sends the data message to a corresponding terminal device, so that the problem that the terminal device cannot directly access the network multicast service through the home gateway in the related art is solved, and the terminal device can directly access the network multicast service through the home gateway is realized; on the other hand, the home gateway maintains the multicast information table based on the IP address of the terminal device, so that the terminal device is not limited to access through a physical LAN port, and can also access through WIFI, thereby expanding the range of multicast application based on an application provider network.
An exemplary embodiment of the present disclosure further provides a device for implementing home multicast, which is shown in fig. 9 and may include: an information table establishing module 910, a multicast application sending module 920, and a home multicast implementing module 930. Wherein:
