Embodiment 1

[0039] In this embodiment 1, for the multicast transmission of the private network multicast protocol message, it is specifically transmitted through the first public network default multicast distribution tree of the default multicast group corresponding to the MVPN, and for the private network multicast data message The multicast transmission is specifically performed through the second public network default multicast distribution tree of the default multicast group corresponding to the MVPN.

[0040] Figure 5 Shown is the flowchart of the multicast packet transmission method provided in Embodiment 1 of the present invention, specifically including the following processing steps:

[0041] Step S501 , the user terminal in the MVPN sends a private network multicast message that needs to be multicast transmitted to the PE connected to it; the private network multicast message carries an active source address and a private network destination address.

Embodiment 2

[0069] In this embodiment 2, for the multicast transmission of the private network multicast protocol message, it is specifically transmitted through the first public network default multicast distribution tree of the default multicast group corresponding to the MVPN, for the private network multicast data message The multicast transmission is specifically transmitted through the public network data multicast distribution tree of the data multicast group corresponding to the MVPN and corresponding to the private network destination address in the private network multicast data packet.

[0070] Figure 6 Shown is the flowchart of the multicast packet transmission method provided in Embodiment 2 of the present invention, specifically including the following processing steps:

[0071] Step S601 , the user terminal in the MVPN sends a private network multicast message that needs to be multicast transmitted to the PE connected to it; the private network multicast message carries an...

Embodiment 3

[0099] Based on the same inventive concept, according to the multicast message transmission method provided by the above-mentioned embodiments of the present invention, correspondingly, Embodiment 3 of the present invention also provides an operator edge device, the structural diagram of which is as follows Figure 7 shown, including:

[0100] The receiving unit 701 is used to receive private network multicast messages that need to be multicast transmitted in the multicast virtual private network MVPN;

[0101] A determining unit 702, configured to determine whether the received private network multicast message is a private network multicast protocol message or a private network multicast data message;

[0102] The first transmission unit 703 is configured to, when it is determined that the private network multicast message is a private network multicast protocol message, transmit the message in the public network through the first multicast distribution tree of the multicast...

Abstract

The invention discloses a multicast message transmission method and a provider edge device (PE). The method comprises the following steps that: receiving a private network multicast message which needs to be performed multicast transmission in multicast virtual private network (MVPN) by the PE; determining whether the received private network multicast message is a private network multicast protocol message or a private network multicast data message; when the private network multicast message is determined to be the private network multicast protocol message, carrying out multicast transmission to the private network multicast protocol message on a public network through a first multicast distribution tree of a multicast group corresponding o the MVPN; when the private network multicast message is determined to be the private network multicast data message, carrying out multicast transmission to the private network multicast data message on the public network through a second multicast distribution tree of the multicast group corresponding o the MVPN. By using a scheme provided by embodiments of the invention, when the private network multicast message, which is packaged as the public network multicast message, is transmitted on the public network, distinguish between the private network multicast protocol message and the private network multicast data message can be realized.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a multicast message transmission method and operator edge equipment. Background technique [0002] Currently, Border Gateway Protocol / Multi-protocol Label Switching (BGP / MPLS, Border Gateway Protocol / multi-protocol label Switching) method to establish a virtual private network (VPN, Virtual Private Network), that is, BGP / MPLS VPN. For the multicast message transmission between user terminals in the VPN network (i.e. private network) in the BGP / MPLS VPN environment, the multicast domain MD scheme is widely used now, and the main process of the MD scheme is as follows: [0003] Each VPN network that transmits multicast packets is called a multicast virtual private network (MVPN, Multicast Virtual Private Network), and a protocol-independent multicast routing protocol (PIM , Protocol Independent Multicast), the operator's edge device PE (Provider Edge Device) connected to ea...
