Description
Technical field
The present invention relates to the network communications technology, more particularly to BIER (the Bit Indexed Explicit in multicast field
Replication, the explicit duplication based on position index) in technology, a kind of transmission method of control information, device and system.
Background technology
IP multicasting technologys realize efficient data transmission point-to-multipoint in IP network.Netowrk tape can effectively be saved
It is wide, reduce offered load, so real time data transmission, multimedia conferencing, data copy, IPTV (IPTV),
All many-sides such as game and emulation are all widely used.Present multicasting technology typically adopts PIM (Protocol
Independent Multicast, Protocol Independent Multicast) agreement (including Protocol independent multicast-sparse mode (PIM-SM) and
Protocol Independent Multicast-dense mode (PIM-DM)), MSDP (Multicast Source Discovery Protocol, multicast
Feed Discovery agreement) etc. realize, one of these multicast protocols is to need to build a kind of control plane multicast tree the characteristics of common, profit
With this multicast tree by network plane logic arrangement for tree-shaped, to realize that the point-to-multipoint data forwarding and loop of multicast forwarding are kept away
Exempt from, this intermediate node to build multicast routing protocol of the distribution tree as core is required for safeguarding complicated multicast forwarding letter
The state of breath, as the scale of network is increasing, in the case that multicast data traffic grows with each passing day, this multicasting technology faces
Challenge in terms of increasing cost and O＆M.
For this purpose, industry proposes a kind of new technology for building multicast forwarding path, referred to as BIER (Bit
Indexed Explicit Replication, the explicit duplication based on position index) technology, the technology propose it is a kind of it is new not
The multicasting technology framework for building multicast distribution tree is needed, as shown in figure 1, the router for supporting BIER technologies is referred to as BFR (Bit-
Forwarding Router, bit forwarding router), a multicast forwarding domain being made up of BFR is referred to as BFR domain,
The edge in BIER domains, the equipment that BFIR encapsulation is carried out to the multicast packet of user is referred to as BFIR (Bit-Forwarding
Ingress Router, bit forwarding ingress router), the edge BFR equipment for decapsulating BIER data messages is referred to as BFER
(Bit-Forwarding egress Router, bit forwarding egress router), multicast packet enters BIER by BFIR encapsulation
Domain, the head that BIER is depended in BIER domains is forwarded, and leaves BIER domains via one or more BFER equipment,
In BIER domains, receive and forward the equipment of BIER messages to be referred to as transit (forwarding) BFR of the BIER messages.One BFR according to
It can be both BFIR role that the difference of encapsulated message is conciliate in encapsulation, can be again BFER role.
In BIER domains, one is distributed whole to every BFR (intermediate forwarding nodes can distribute can not also be distributed)
Bit position (bit position) globally unique in BIER sub-domain (subdomain), every BFER are by the bit of oneself
Position is using IGP (Interior Gateway Protocol, Interior Gateway Protocol) agreement in BIER domain domains
Flood, all of bit position constitute a bitstring (Bit String), transmission and road of the data message in BIER domains
By depending on bitstring.When other BFR have received the heading for including BIER, carry according in BIER headings
Bitstring forwarded based on Bit Forwarding Table (bit forward table or claim position index forward table).It is this
The principle forwarded based on BIER bit positions will be previously required to be changed to use bit-identify based on the forwarding for building multicast distribution tree

Fig. 2 describes the process of BIER forwardings, and BFR1 is BFIR for ingress BFR, and BFR5, BFR6 and BFR7 are
Egress BFR are BFER, and the bit position of three BFR are respectively 0001,0010,0100.Egress BFR pass through in advance
(such as IS-IS, (Intermediate system to intermediate system, intermediate system is to middle system for IGP agreements
System) agreement, or OSPF (Open Shortest Path First, ospf) agreement) in BIER
The bit position of its own are noticed in domain, BFR1 have received the logical of the bit position of BFR5, BFR6 and BFR7
After announcement, in local position index forward table these information are preserved.When BFR1 have received multicast message, it is assumed that the multicast message is needed
BFR5 and BFR6 is transferred to, then BFR1 calculates the value of the Bitstring of the message according to the prior mapping relations for preserving
For 0101, the multicast message of user is encapsulated as into BIER messages, the Bitstring fillings 0101 in wherein BIER Header are simultaneously
BFR2 is forwarded to, BFR2 is received after message, searches the entry in the position index forward table for preserving in advance, according to entry, message is needed
Be forwarded to BFR3, then by Bitstring with the item entries of the matching F-BM (Forwarding Bit Mask forwarding ratio
Special mask table) do and operation, the Bitstring in obtaining 0101, BFR2 using 0101 as BIER Header refills BIER
Message, and BFR3 is forwarded the packet to, BFR3 have received after the message, search the position index forward table of oneself, and BFR3 has 2 bars
Matching record, represents respectively message next-hop and is forwarded to BFR4 and BFR6, and for first entry, BFR3 is by Bitstring's
Value is done and operation with the F-BM in entry, obtains result for 0001, in second entry, the value of Bitstring with F-BM do with
The result of operation is 0100, then message is forwarded BIER messages to BFR4 and BFR6 by BFR3 from 2 interfaces respectively, wherein BFR4's
The value of the Bitstring of BIER Header is 0001, and the value for being forwarded to the Bitstring of the BIER Header of BFR6 is
0100.For the message for reaching BFR6, it is found that the value of bitstring as the bit position for oneself noticing, is represented certainly
Oneself is the destination of the message, decapsulates BIER messages.And when reaching message arrival BFR4, successively aforesaid forwarding principle, incites somebody to action
Message is forwarded to BFR5, and by BFR5 BIER messages are decapsulated, and so far, transmission of the multicast message in BIER domains is completed, by group
Report receiving node BFR4 and BFR6 that text is forwarded to multicast by the BFR1 nodes of entrance.
The issue of existing BIER control messages be by extend IGP or BGP (Border Gateway Protocol,
Border Gateway Protocol) come what is issued, such as IGP agreements, can by all nodes of message flooding to the BFR in whole BIER domains,
And for some control messages, such as border has which multicast group address is accessed, or which VPN that border addition is
