Description
Technical field
(Internet Protocol, IP) multicasting technology relate in particular to a kind of method, equipment and system that realizes designated router to register at convergence point to the present invention relates to Internet protocol.
Background technology
The IP multicast is meant that in IP network certain that packet is sent in the network with the form that transmits (best-effort) as possible determines the node subclass, and this subclass is called multicast group (multicast group).The IP multicasting technology has solved single-point effectively and has sent the problem that multiple spot receives, and has realized the efficient data transmission of IP network mid point to multiple spot, can save the networking bandwidth in a large number, reduce offered load.Can utilize the networking multicasting technology to carry out some new value-added services easily, as: internet information service such as online live, Web TV, long-distance education, tele-medicine.
In realizing the IP cast communication, the multicast route technology is one of its key technology.The main task of multicast routing protocol is the distribution tree of structure multicast, makes the multicastapackets data can be sent to corresponding multicast member.Different with use according to the distribution to the multicast member in the network, multicast routing protocol is divided into two classes: dense mode Routing Protocol and sparse mode Routing Protocol.Wherein, (Protocol Independent Multicast-Sparse Mode PIM-SM) is multicast pattern in a kind of territory commonly used to Protocol Independent Multicast-Sparse Mode.PIM-SM carries out the forwarding of multicast packet by setting up multicast distribution tree, and wherein multicast distribution tree is divided into two kinds: (Rendezvous Point is the shortest path tree of root for the shared tree of root with multicast source S RP) with the convergent point of group G correspondence.As shown in Figure 1, PIM-SM finishes the foundation and the maintenance of multicast distribution tree by the adding/beta pruning mechanism that shows.According to this mechanism, satisfying outgoing interface for empty, perhaps finished shortest path tree (Shortest Path Tree, SPT) under the condition of Qie Huaning, receive any logon message (Register) again, transmission stopped registration messages (Register Stop) is triggered in the capital, and (Designated Router, DR), the speed of the stopped registration messages of RP transmission at this moment is the same with the speed of data message to the source Designated Router.Source DR is after receiving such stopped registration messages, with registration outgoing interface (Reg Tunnel) deletion of correspondence.
Having on the DR of source under the situation of a large amount of list items, if the data transmission rate of these list items is very high, each logon message all can return a stopped registration messages over there from RP, delivering to control unit on each stopped registration messages is all understood handles, when stopped registration messages is too much, will take more processing resource, like this all protocol massages of PIM-SM, as add prune packet, hello, RP message and will be dropped, stopped registration messages also can be dropped certainly.As certain source group (S, G) (wherein, S:Source (source), G:group (group)) sends after the registration probe messages, send the basis (S that returns from RP, G) stopped registration messages is because other (S, G) stopped registration messages is too much, and is dropped, and can cause registration timer overtime, the registration outgoing interface is added to return again, and restart to send the log-on data message, and at this moment will further increase logon message and stopped registration messages quantity in the network, increase the burden of control unit, vicious circle appears in consequence aggravation packet loss.
As shown in Figure 2, the very first time, source DR sends a large amount of (S1, logon message G1), and (S2, registration probe messages (Probe) G2) is because RP can respond a large amount of (S1, G1) stopped registration messages causes that (S2 G2) gets stopped registration messages and lost; Caused for second time, source DR can send in a large number (S2, logon message G2) cause at last (S1, stopped registration messages G1) is lost, the registration outgoing interface is added to return again, sends once more that a large amount of (S1, logon message G1) constitutes vicious circle with this.
Too much when stopped registration messages, be dropped for continuous 4 times and same adding prune packet occurs, the outgoing interface ageing timer that will cause router to be preserved can not get upgrading for a long time, and ageing timer is overtime, and outgoing interface is removed, and data can not normally be transmitted.Equally, when same neighbours' hello packet is dropped for continuous 4 times, cause long-time the grade less than renewal of neighbor information of router preservation, at this moment can cause neighbours' timer expiry, neighbours are deleted.
And a plurality of identical stopped registration messages of source DR reception is insignificant at one time.After source DR receives first stopped registration messages, state machine enters the beta pruning state, in the time, receives same stopped registration messages at certain hour (the registration inhibition cycle subtracts the registration detect cycle) once more afterwards, to directly abandon, without any the action of other meaning.
By as seen above-mentioned, in the prior art,, cause the greatly processing resource of consumption systems because stopped registration messages is too much, cause some important protocol message of PIM-SM to be dropped, status error occurs, even enter vicious circle, can't operate as normal.It also is skimble-skamble simultaneously handling a plurality of identical stopped registration messages at short notice.
