Embodiment 1

[0066] According to the embodiment of the present invention, aiming at the problem of cross-domain forwarding, an embodiment of a network architecture for message cross-domain forwarding is provided, as shown in image 3 As shown, the network architecture includes: a hierarchical controller located in the first domain AS100, a bit index display replication-convergence point device BIER-RP, a bit index forwarding ingress router BFIR, and a bit index forwarding egress router BFER.

[0067] The hierarchical controller is used to manage cross-domain routing information, network topology information and multicast group information.

[0068] BIER-RP is respectively connected to the hierarchical controller and BFIR, and is used to notify the hierarchical controller of the cross-domain multicast group address, send cross-domain routing information to the second domain AS200, and notify the received cross-domain multicast group address in the first domain. routing information.

Embodiment 2

[0142] According to an embodiment of the present invention, a method embodiment of a message sending method is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and , although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0143] Figure 17 is a flow chart of a message sending method according to an embodiment of the present invention, such as Figure 17 As shown, the method includes the following steps:

[0144] Step S1701, the bit index of the first field shows that the replication-convergence point device BIER-RP notifies the controller of the cross-domain multicast group address.

[0145] Step S1702, after receiving the multicast data message requesting cross-domain transmission to the second domain, the BFIR forwards the ...

Embodiment 3

[0161] The embodiment of the present invention also provides a message sending device. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and what has been described will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0162] Figure 18 is a schematic diagram of a message sending device according to an embodiment of the present invention. Such as Figure 18 As shown, the device may include: a first notification unit 181 and a transmission unit 182 .

[0163] The first notification unit 181 is used to control the bit index display of the first domain and the replication-rendezvous point device BIER-RP to notify the controller of th...

Abstract

The invention provides a message sending method and apparatus and a message cross-domain forwarding network architecture. The message sending method comprises steps: a bit indexed explicit replication-rendezvous point (BIER-RP) device of a first domain announces an address of a cross-domain multicast group to a controller; and after a bit-index forwarding ingress router (BFIR) of the first domainreceives a multicast data message requesting to be transmitted across a domain to a second domain, the BFIR transmits the multicast data message to a bit-index forwarding egress router (BFER) of the first domain, and the BFER forwards the multicast data message to the second domain. The technical problem that many network resources need to be occupied when the multicast data message is transmittedin a related technology can be solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a message sending method and device, and a network architecture for message cross-domain forwarding. Background technique [0002] IP multicast technology realizes efficient point-to-multipoint data transmission in IP network, which can effectively save network bandwidth and reduce network load. Therefore, IP multicast technology is widely used in real-time data transmission, multimedia conference, data copy, IPTV, games and Simulation and many other aspects have a wide range of applications. At present, multicast technology is generally realized by Protocol Independent Multicast (PIM protocol for short, including PIM-SM, PIM-DM), Multicast Source Discovery Protocol (Multicast Source Discovery Protocol, MSDP protocol for short), etc. These multicast protocols A common feature of all is the need to build a control plane multicast tree, using this multicast tree to process the lo...
