Embodiment 1

[0096] Figure 5 It is a flow chart of the information transfer method based on BIER technology provided by Embodiment 1 of the present invention. according to Figure 5 The flow shown can transfer the control information (including the identification information and the corresponding information) of the predetermined flow between the BIER forwarding nodes, so as to achieve the purpose of generating the forwarding path corresponding to the identification information by the BIER forwarding nodes.

[0097] Such as Figure 5 As shown, the method provided in this embodiment includes the following steps:

[0098] Step 501: The entry node of the BIER network judges according to the traffic situation, assigns corresponding identification information to the traffic that needs to take the label identification path, and maps the corresponding exit node set or link set information; here, according to the predetermined traffic corresponding exit A set of nodes, or a set of desired TE l...

Embodiment 2

[0110] Figure 7 It is a schematic diagram of the implementation of the information transfer method based on the BIER technology provided by Embodiment 2 of the present invention. In this embodiment, a predetermined flow, or a certain type of flow, is identified in the form of a label set, and the set of exit nodes that the predetermined flow needs to reach is converted into bit string information, and these information are combined with Information such as subdomains, set identifiers, and bit string lengths are advertised through protocol extensions, etc. Each BIER network node forms a forwarding entry according to identification information (label set). When the data message is forwarded, it is directly forwarded to the next hop node through the forwarding entry formed by the label set. For example, here, the label 200 corresponding to the ingress node 1 and the label 50 allocated to the predetermined traffic are combined as identification information (ie, corresponding to...

Embodiment 3

[0118] Figure 8 It is a schematic diagram of the implementation of the information transfer method based on the BIER technology provided by Embodiment 3 of the present invention. In this embodiment, a special method is used to identify predetermined traffic, or a certain type of traffic. For example, here, a certain type of traffic is identified as ABCDEFG, and the identification information and the corresponding egress node set or chain are notified through signaling. Road set (or bit string information generated according to the exit node set and / or link set information), or the controller sends identification information and the corresponding exit node set or link set (or according to the exit node set and / or link set After the bit string information generated by the collection information), the forwarding node forms a corresponding forwarding entry, and the forwarding node can directly forward the traffic carrying the identification information to the next hop according t...

Abstract

The invention discloses an information transmission method, an information transmission device and an information transmission system. The method comprises steps: identification information is distributed for a predetermined flow, and the information corresponding to the identification information is determined, wherein the information corresponding to the identification information comprises information formed by an exit node set and/or a link set; and the identification information and the information corresponding to the identification information are transmitted to one or more network nodes. The above method can improve the network forwarding efficiency, and development of a multicast technology and the network is thus promoted.

Description

technical field [0001] The present invention relates to the communication field, in particular to an information transmission method, device and system. Background technique [0002] Multicast data communication is playing an increasingly important role in the current Internet. Interactive Personality TV (IPTV, Interactive Personality TV), Net-Meeting (Net-Meeting), and live game live broadcasts all use multicast technology. Existing multicast technologies include: Protocol Independent Multicast (PIM, Protocol Independent Multicast), Internet Group Management Protocol (IGMP, Internet Group Management Protocol), Multicast Listener Discovery Protocol (MLD, Multicast Listener Discovery Protocol), etc. In the initial small-scale application scenarios, these existing protocols can meet the needs of users. However, as the multicast application becomes more and more extensive, the networking forms become more and more complex, and the multicast is directly applied to the Internet, ...
