It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Fig. 1A is an exemplary flow diagram of a multicast data transmission method according to some embodiments of the invention. As shown in fig. 1A, the multicast data transmission method of this embodiment includes steps S102 to S110.
In step S102, a first Multicast Tunnel End Point (MTEP) receives a first Multicast packet sent by a Multicast source, where the first Multicast packet includes an original Multicast source address and an original Multicast group address.
The first MTEP may be carried on an ME (Multicast Edge). The same ME may carry one or more MTEPs.
In step S104, the first MTEP encapsulates the first multicast packet into a second multicast packet, where a multicast source address of the second multicast packet is an address of the first MTEP, the multicast group address is a public network multicast group address corresponding to the original multicast group, and the public network multicast address may be, for example, an address of a second MTEP at an opposite end of the tunnel.
The first MTEP may store a mapping relationship between the original multicast group address and the public network multicast group address in advance. In some embodiments, the mapping relationship may be issued by the controller.
In the mapping relationship, the same public network multicast group address may correspond to a plurality of original multicast group addresses, that is, different original multicast group addresses may be mapped to the same public network multicast group address. Therefore, the multicast packets corresponding to different multicast group addresses may be transmitted to the same device or module in the public network, for example, to the same ME or MTEP, and then further forwarded by the receiving device.
An exemplary structure diagram of the second multicast packet may be as shown in fig. 1B. In fig. 1B, the second multicast message includes an Ethernet Header (Ethernet Header), an outer IP Header, an inner IP Header, and a payload (Playload); the outer layer IP header at least comprises a protocol type with a length of 8 bits (bit), a source IP address with a length of 32 bits, and a destination IP address with a length of 32 bits, wherein the source IP address is the IP address of the first MTEP, the destination IP address is the IP address of the public network multicast group, and the outer layer IP header also comprises other fields with a length of 72 bits and 16 bits.
In step S106, the first MTEP forwards the second multicast message to the second MTEP according to the public network multicast address. That is, the first MTEP can perform transparent forwarding only according to the address of the outer layer without paying attention to the original multicast group address when forwarding. The second MTEP may be the other end point of the tunnel in which the first MTEP is located.
In some embodiments, the first MTEP may transmit the second multicast message over a wide area network, IP backbone. Other devices on the network also rely on the outer header of the second multicast message for multicast forwarding.
In step S108, the second MTEP decapsulates the second multicast packet to obtain the first multicast packet.
In step S110, the second MTEP forwards the first multicast message to the device corresponding to the original multicast group address.
The method of the embodiment adopts a transmission mode of two layers of multicast addresses, the two layers of multicast addresses are respectively oriented to a wide area network and a platform ad hoc network, the two layers of multicast addresses are not interfered with each other, any layer can be flexibly disposed according to the actual service on the basis of sufficient multicast addresses, products are overlapped on the whole, and the address scale is doubled. In addition, the complexity and the link length of the network environment at each stage are reduced, and the possibility of failure is reduced.
In some embodiments, the controller may manage and issue a mapping between the original multicast group address and the public network multicast group address. An embodiment of the mapping relationship issuing method of the present invention is described below with reference to fig. 2.
Fig. 2 is an exemplary flowchart of a mapping relationship issuing method according to some embodiments of the present invention. As shown in fig. 2, the mapping relationship issuing method of this embodiment includes steps S202 to S206.
In step S202, the controller receives a multicast service application, where the multicast service application includes a multicast group address to be used by each multicast platform, that is, an original multicast group address.
In step S204, the controller fragments the public network multicast group address for each original multicast group address, and establishes a mapping relationship between the two.
In step S206, the controller issues the mapping relationship to the MTEP in the network.
In some embodiments, the controller may issue the mapping relationship to the ME carrying the MTEP through the southbound interface, so as to facilitate monitoring and management, and is easy to implement and wide in application range.
By the method of the embodiment, the controller can comprehensively allocate the public network multicast address according to the situation of the whole network.
In some embodiments, the original multicast group addresses corresponding to the same original multicast source address correspond to the same public network multicast group address in the mapping relationship. That is, the multicast packet sent by the same multicast source may be handed to the same MTEP for decapsulation processing and forwarding.
For example, the multicast source address corresponding to the platform 1 is S1, and the multicast group addresses are G1 and G2; the multicast source address corresponding to the platform 2 is S2, and the multicast group addresses are G3 and G4. G1 and G2 may be selectively mapped to a public network multicast group address G10 and G3 and G4 may be selectively mapped to a public network multicast group address G20.
An embodiment of the multicast data transmission method of the present invention is described below with reference to fig. 3A and 3B.

Both ME31 and ME32 carry MTEPs, which are connected via an IP backbone and are separately connected to controller 30.

In step S302, the multicast source devices 3111, 3112, 3121, 3122 transmit the original multicast data (S1, G1), (S2, G2), (S3, G3), (S4, G4) to the ME1, respectively. (Sn, Gn) indicates that the multicast source address is Sn and the multicast group address is Gn.
In step S304, the MTEP in ME1 encapsulates the original multicast data into a new packet, and converts (S1, G1), (S2, G2) into (11.1.1.1, 233.1.1.1) and (S3, G3), (S4, G4) into (11.1.1.2, 233.1.1.2) with its own IP address as the multicast source address and the public network multicast group address as the multicast group address.
In step S306, the ME1 forwards the encapsulated new packet to the backbone network. Multicast data packets (11.1.1.1, 233.1.1.1) and (11.1.1.2, 233.1.1.2) are transmitted along a Multicast distribution tree of a PIM (Protocol Independent Multicast) Protocol in a backbone network.
In step S308, the MTEP in ME2 decapsulates the received multicast data packets (11.1.1.1, 233.1.1.1) and (11.1.1.2, 233.1.1.2), and restores them to the original multicast data (S1, G1), (S2, G2), (S3, G3), (S4, G4).
In step S310, the ME2 delivers the original multicast data to the multicast group devices 3201, 3202, 3203, 3204 corresponding to G1, G2, G3, G4, respectively.
Embodiments of the present invention may be applied to a variety of application scenarios. For example, in a scenario where a certain hotspot event occurs, a hotspot information source may be first transmitted to each media and platform, and then each media and platform may be used as a multicast source to encapsulate hotspot data through an MTEP and transmit the hotspot data to a network, and an opposite-end MTEP receives the multicast data and then decapsulates the hotspot data, and then distributes the hotspot data to a user group. For example, traffic having regional directionality or a trend may be first propagated from a source point to nodes such as provinces and cities, and then sent from the nodes of each province and city to a user group. The transmission process also adopts encapsulation and decapsulation modes, which are not described in detail here.
