Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of many topological networks retransmission method and corresponding device thereof.
Background technology
In three layers of traditional route network, only the destination address based on message forwards, and causes distinguishing message according to business, cannot carry out meticulous control to business.Simultaneously to based on SPF(Shortest Path First, SPF) Routing Protocol of algorithm, whole net shares a shortest path tree, shares a Zhang Tuo and flutters, and easily cause on optimal path flow to transfer now congested, and on suboptimum link, bandwidth is wasted.For addressing this problem, MT(Multi-Topology has been proposed, how topology) concept.Support, after MT, can divide Global Topological as required, be divided into multiple subtopologies, different like this flows just can be walked different topologys.For example, refer to Fig. 1, voice flow can be walked subtopology A, and video flowing can be walked subtopology B.For subtopology A, Router B does not exist; And for subtopology B, it is thought between Router A and Router D, and it is connected between Router B and Router C, not have available link.In order to indicate different topologys in network, introduce the concept of MT ID, carry out the unified topology of distinguishing of the whole network by MT ID.The scope that can be used as how topological ID on the current equipment wherein stipulating in RFC5120 is 6 to 3995.
Carry out the unified topology of distinguishing of the whole network by MT ID, the Routing Protocol of control plane and Forwarding plane carry out adaptation with respect to three layers of traditional route network to be revised.The Routing Protocol of control plane, as IS-IS(Intermediate System to Intermediate System, Intermediate System-to-Intermediate System) agreement, by at LSP(Link State Protocol Data Unit, Link State Protocol Data Unit) in carry expansion TLV(Type Length Value, type lengths values), Link State in different topology is described, and on equipment, safeguard the LSDB(Link State Data Base of different topology, LSD).When the Routing Protocol of control plane carries out route calculating, carry out SPF(Shortest Path First, SPF according to the LSDB of different topology respectively) calculate, for each topology is safeguarded a routing table and transmits.
When Forwarding plane carries out message repeating, first according to user configured strategy, message is mated, according to matched rule, different messages is incorporated in different topologys, message is introduced into after different topologys, then according to transmitting under this topology, carries out IP forwarding.MT has special RFC to the modification of control plane Routing Protocol in realizing at present, but the modification for Forwarding plane does not explicitly call for, each manufacturer is all by configuration MT strategy, come destination address, source address, dscp(Differentiated Services Code Point to message, differentiated services code points) font, protocol type field filter.
But according to strategy, message is filtered to this problem below that exists:
1, due to the forwarding in topology or IP-based, so just require to move in network on all devices of MT and all need to configure MT strategy, in network, every equipment is in the time carrying out data message forwarding, all need to check many topology strategies, judge that by policy filtering data message forwards in that topology, device hardware is had relatively high expectations, and forward efficiency is low.
2, will carry out meticulous division to message, just need to configure complicated MT strategy, can configure multiple coupling list items in MT strategy, as long as a wherein list item of coupling, flow just can enter this MT and forward.The hardware chip function of mid and low-end products is limited, to the not support hardware forwarding of complicated strategy, can only forward by software, greatly reduces the performance of MT forwarded; If the whole network all uses high-end devices, can greatly improve the cost of networking.

Referring to accompanying drawing, each embodiment of the application is described in further detail.
Referring to Fig. 2, in the exemplary a kind of execution mode of the present invention, provide a kind of retransmission method of many topological networks, the method is carried out following steps:
Step S201, set up MT label forwarding list item for many topologys of this plant maintenance, described MT label forwarding list item comprises the corresponding relation of described many topologys and MT label;
Step S202, in current network, send link advertisement message, described link advertisement message identification MT label forwarding ability;
Step S203, receive the link advertisement message of miscellaneous equipment in current network and carry out the calculating of many topologies, and in each many topologys of this plant maintenance to support the equipment of how topological label forwarding ability as MT label corresponding to the route forwarding table items mark of down hop;
Step S204, in the time receiving the data message of miscellaneous equipment and comprise MT label, in the MT of local maintenance label forwarding list item, find corresponding topology according to this MT label, and ejecting after this MT label according to the forwarding of tabling look-up of this topological route forwarding table.
In the present embodiment, support the equipment of the present embodiment to configure after many topologys in this locality, for each many topological arrangement MT ID, and on equipment, record the corresponding relations of MT ID and many topologys, then the many topologys that are local maintenance according to this corresponding relation are set up MT label forwarding list item, described MT label forwarding list item comprises the corresponding relation of described many topologys and MT label, and wherein, the MT ID that the equipment of respectively supporting the present embodiment is each many topological arrangement is identical.Described MT label forwarding list item can be as following table, and in the present embodiment, label is identical with topological MT ID:
The wherein label of No. 0 corresponding underlying topology of label, because the scope that stipulates can be used as on current equipment how topological ID in RFC5120 is 6 to 3995, therefore in MT label forwarding list item, in respective user networking, be No. 6 and later label in each many topologys of this locality configuration.Determine after corresponding topology at the label based on MT ID, POP(ejects) MT label, removes and enters corresponding topology after label and forward.
At present, in the practical application of MT network, control plane adopts Intermediate System to Intermediate System, by carry expansion TLV field in the IS-IS LSP message sending, describes the Link State in different topology.The equipment that moves Intermediate System to Intermediate System in MT network is by collecting in current MT network the LSP to the whole network inundation from other equipment, create and safeguard the LSDB of different topology, and in the time carrying out route calculating, carry out SPF calculating according to the LSDB of different topology respectively, for each topology is safeguarded respectively an independent route forwarding table.And in the present embodiment, be the notice by Intermediate System to Intermediate System being expanded to realize MT label forwarding ability.
In the present embodiment, NLPID(Network Layer Protocol Identifier in the supported protocol TLV of Intermediate System to Intermediate System LSP, network layer protocol identifier) new ability parameter 900 of Field Definition, be used for marking equipment and whether there is MT label forwarding ability.Refer to following table:
Supported protocol TLV is the agreement that the originating equipment for specifying message is supported, for the agreement of each support, the NLPID in TLV can have a corresponding NLPID value.In the present embodiment, when certain equipment has MT label forwarding ability, the NLPID in the LSP message that this equipment sends in supported protocol TLV will increase a value 900 newly.Therefore, the equipment of all support MT label forwarding abilities, by collecting in current MT network the LSP to the whole network inundation from miscellaneous equipment, can determine in current MT network, whether miscellaneous equipment has MT label forwarding ability, and set up the LSDB of local maintenance according to the LSP collecting; In the time carrying out how topological SPF route calculating, if the originating equipment of the LSP message receiving can add shortest path tree to, further check in the supported protocol TLV field of this LSP message and whether carry newly-increased NLPID value 900, if, the equipment that shows to send this LSP message has the ability of MT label forwarding, in each many topologys of this plant maintenance, the MT label of correspondence on the equal mark of route forwarding table items take this equipment as down hop, wherein this MT label is the MT ID of the many topologys in described route forwarding table items place.
When supporting the equipment of MT label forwarding ability as the edge device in current MT network, while forwarding the data message from user's side to miscellaneous equipment, first determine the forwarding topology of this data message according to default MT strategy.So-called MT strategy, thereby refer to using property values different in data message as coupling according to the different matched rule forming, different matched rule corresponding to topology, as long as the arbitrary described matched rule of the property value in the data message of receiving coupling enters the forwarding of tabling look-up of topology that this matched rule identifies.Such as in actual applications, thereby this matched rule can be take the destination address of data message, source address, DSCP font, protocol type field etc. as coupling is according to the matched rule forming.If the recipient of this data message down hop has MT label forwarding ability, the route forwarding table items that this data message is corresponding has corresponding MT label, this equipment is before forwarding this data message so, this MT Tag Packaging is arrived to this data message, and then be transmitted to the recipient of down hop.Refer to Fig. 3, in the present embodiment, MT tag head is between two layers of head and IP message, and wherein the type field value of two layers of head is newly-increased NLPID value 900.MT label value is used for confirmation message and enters which topology and forward; EXP field, is used for carrying out QOS processing, and its concrete value is identical with the TOS field in IP message, and field is below to retain position.
In the time supporting that MT label forwarding capacity device is not the edge device in current MT network, while receiving the data message from miscellaneous equipment in current MT network, first need to judge whether this data message has encapsulated MT label.If this data message does not encapsulate MT label,, determine the forwarding topology of this data message according to default MT strategy, and enter the forwarding of tabling look-up in this topological route forwarding table.If this data message has encapsulated MT label, the MT label carrying according to this data message is searched the forwarding topology that this data message is corresponding in the MT of local maintenance label forwarding list item, if do not found, this MT label is being carried out after POP operation, after ejecting this MT label, determine the forwarding topology of this data message according to existing strategy again, and the forwarding of tabling look-up in this topological route forwarding table.
When having determined after the forwarding topology of the data message of receiving, enter this topological route forwarding table to this data message table look-up forward time, if corresponding route forwarding table items has corresponding MT label, be transmitted to again the recipient of down hop after using this MT label to encapsulate this data message.If the route forwarding table items that this data message is corresponding does not have corresponding MT label,, directly forward according to IP message repeating flow process.
Known by above description, in the present embodiment, when the equipment that has MT label forwarding ability in by MT network when the data message that has not encapsulated MT label forwards, forward after still determining corresponding many topologys by default MT strategy; When the equipment that has MT label forwarding ability in by MT network when the data message that has encapsulated MT label forwards, directly determine that by MT label the topology under message forwards, thereby improved the forward efficiency of MT network-internal apparatus; Now, in actual MT networking process, can only need the edge device of MT network to use high-end devices, greatly reduce hardware requirement and networking cost to equipment.
