Description
Technical field
The present invention relates to the communications field, in particular to a kind of control method and device of flux of multicast.
Background technology
Bit position index displaying duplication (Bit Index Explicit Replication, referred to as BIER) technology is recently international mutual
The multicast forwarding technology that networking project task groups (Internet Engineering Task Force, referred to as IETF) begin one's study,
Its core concept is as shown in figure 1, the node in network is all only represented with one BIT, and flux of multicast is passed in go-between
It is defeated, it is not to be presented with multicast IP packet forms, but encapsulate in a specific BIER head, BIER directly or indirectly
Including BIER essential informations (can directly include Sub-domain sub-domain informations, Bit String Length bit bit string length information,
This three elements information of Set Identifier set identifiers information, can also indirect this three elements information of unique mark by way of label)
With Bit String bit bit string information.
Wherein, BIER essential informations are used to navigate to bit position index forward table (Bit Index Forwarding Table, referred to as),
Bit String bit bit string information labelings all purposes node of the multicast data flow, these information of go-between in BIER
Search BIFT to be route, ensure that flux of multicast can be sent to all purposes node with optimal path.
Flow specification Flow Specification technologies are studied on IETF based on Border Gateway Protocol (Border Gateway
Protocol, referred to as BGP) extension notice flow specification rule, and flow specification rule is based on to the flow received on the router
Carry out the technology of dynamic control.Specifically, flow specification rule is a series of component type (Component that can be coarse to fine by granularities
Type) constitute；The dynamic and quick of the rule of flow specification on each BGP Speakers is realized as chain of command by bgp protocol
Notice and revocation, improve preventing distributed refuse service attack in network (Distributed Denial Of Service, referred to as
DDOS) the ability of attack, it is to avoid pass through the method for static configuration in legacy network so that the control of network traffics is dynamic
With it is flexible.
Fig. 2 is the technical principle schematic diagram of BGP flow specification Flow Specification in correlation technique, is flowed referring to Fig. 2, BGP
Control equipment notices flow specification rule to each BGP Speaker by extending bgp protocol, and each BGP Speaker are by the flow specification received
Rule is stored in forward table, when receiving flow, and flow specification rule is matched first, what the match is successful, then is advised according to flow specification
Then corresponding action Action instructions perform corresponding action, including filtering, redirection, packet loss etc..
Currently, flow specification Flow Specification primary formats are as shown in figure 3, wherein, Network Layer Reachable Information value field NLRI
Value defined flow specification rules in current RFC5575 are as shown in table 1 below.
As table 1 below can be seen that the current control explanation not being defined to BIER flux of multicast so that network can not realize base
In the dynamic control of the flux of multicast of BIER technologies.
Table 1
For in correlation technique, the problem of dynamic control of the flux of multicast based on BIER technologies not yet proposes effective technical scheme,
Not yet propose effective solution.
