Description
Technical field
The present invention relates to communication field, relate in particular to a kind of method, interface board and router of message up sending.
Background technology
The architecture majority of router is a distributed frame.Under distributed routing environment, control plane is realized the processing of agreement, and datum plane is realized message forwarding.Usually, the unit of being responsible for control plane is called master control borad, is responsible for the interface board that is called of datum plane.A general master control borad and a plurality of interface board of existing in the distribution router.After interface board is received protocol massages from physical interface, can protocol massages be delivered to master control borad by the bus between plate and handle.
The IP multicast is that certain that in IP network packet is sent in the network with the form that transmits is as possible determined the node subclass, and this subclass is called multicast group.The basic thought of IP multicast is, source host only sends a piece of data, and the destination address in this piece of data is a multicast group address; All recipients in the multicast group can receive same data copy, and have only the main frame in the multicast group can receive these data, and other main frames can not be received in the network.
The Internet group member management protocol (IGMP, Internet Group Management Protocol) is that the IPv4 field is used for realizing that main frame adds the agreement of particular multicast group, has three versions, is respectively IGMPv1/v2/v3.In the v1 version, main frame adds certain specific multicast group by the router of Report message notifying adjacency, after router is received, the multicast group timer is set, and creates corresponding multicast group and is used for instructing forwarding; Whether router sends common query message (General-Query) termly and determines to also have under each interface multicast group to exist to main frame; After main frame is received common ground query message, can add the ground multicast group sends to adjacency with the form of Report message router to main frame; After router is received the Report message of existing multicast group, upgrade the multicast group timer; If do not receive the Report message of certain group in a period of time, the multicast group timer expiry, the state of this group is also deleted.
Among the IGMPv2, on the basis of v1, increase the transmission of Leave message.If main frame has left some multicast group, send the router of Leave message to adjacency.After router is received, send group polling message (General-Query) immediately, whether determine to also have under this interface other main frame to want to continue to receive the data of this multicast group, the All hosts that does not leave this group resends the Report message, shows the existence of this main frame.
In IGMPv3, on the basis of v2, increased the overanxious mechanism in source, main frame is by sending the Report message, show that this main frame only wants to receive the data from some particular source, or except that crossing some particular source, data from other sources can receive, respectively corresponding two states: INCLUDE (A) (data in other sources that expression A set is outer do not receive) and EXCLUDE (B) (data in other sources that expression B set is outer all can receive); After main frame is received query message, respond the Report message of IS IN or IS EX type respectively according to the state of each group, if the source that main frame can receive increases or reduces, then initiatively transmission types is that ALLOW (increase) is the Report message of BLOCK (minimizing) type.Cause that the message that the multicast group state changes is called state change message.
In the prior art for IGMP/ multicast listener discovery (MLD, Multicast Listener Discovery) message, the multicast group state that each main frame sends changes message and sends to master control borad by the interface board that is connected with main frame by bus, and master control borad sends to each main frame that is connected with interface board to the query message that each main frame sends by bus.Under the situation that has a large amount of IGMP/MLD main frames to exist, every tens seconds, receive the query message that router sends, each main frame in the network all can be responded a current multicast group state message to master control borad by connected interface board, and message is sent to master control borad by bus from interface board; Bus run between master control borad and the interface board greatly may cause obstruction because bandwidth is certain like this, causes the bottleneck that protocol massages is handled.Master control borad will be handled the message that a plurality of interface boards are received in the router, when in network, having a large amount of message up sending, master control borad has little time to handle at short notice a large amount of messages, at this moment the main frame in the network can be waited for the response of master control borad and can not carry out other work, can not carry out corresponding work with the equipment in other networks that the main frame of waiting for is connected, thereby cause whole network each task to lag behind, exchanges data has some setbacks in the network.
