After label distribution and mapping were finished, the ILM of formation (Incoming Label Mapping goes into the label mapping) table content was as shown in table 1:
Table 1:ILM table
| Go into label | Type of service | The VPN index | Bandwidth | Formation ID | Tag operational | The outgoing label stack | Outgoing interface | |
| 101 | | 100 | 10MB | 1 | Eject | - | Interface 1 | A.A.A.A |
| 102 | VPWS | 100 | 20MB | 2 | Eject | - | Interface 2 | - |
| 103 | | 100 | 40MB | 1 | Eject | - | - | - |
| 104 | | 0 | 80MB | 2 | Exchange | 105 | Interface 3 | B.B.B.B |
In the last table, the processing queue of each Business Processing correspondence of formation ID sign MPLS promptly needs the scheduling processing queue numbering that enters.Equipment is when handling the MPLS message, go into tag entry for four and correspond respectively to four kinds of MPLS business, need to handle respectively according to business characteristic behind the inquiry tag mapping table, because the difference of business characteristic, device interior is bigger to the handling process difference of four list items.
In the said method, during device processes MPLS message, before the label mapping table is not gone in inquiry, can't predict this tagged traffic type, thereby can't determine also which handling process this MPLS message enters, promptly can't instruct next step operation flow shunting from label itself, need huge the going into the label mapping table and could determine type of service of further search space, the shunting processing procedure relative complex of MPLS business.

Embodiment
A kind of MPLS label distribution method of the present invention is gone into some process informations in the label mapping table with prior art, deposits in the MPLS label with the form of message identification, realizes the expanded application to the MPLS label.The flow chart of this MPLS label distribution method as shown in Figure 4, may further comprise the steps:
Step S401, label send the network equipment to tag library application MPLS label, and the process information sign is arranged in the MPLS label.
The size of MPLS label value is 20 bits, in actual use, this 20 bit is not used and is expired, and the FEC capacity of system's support does not generally need so big label range.Therefore, can be with some process informations of going in the label mapping table, the form that identifies with process information directly is stored in the MPLS label.At first, set the corresponding relation between various process informations and the process information sign, this corresponding relation is stored in the tag library; The network equipment is according to concrete needs, to the process information sign of tag library application correspondence, and this process information sign deposited in the MPLS label, carries this process information sign by the MPLS label.
In addition, the application of MPLS label is carried out according to FEC, and a FEC uses an independently MPLS label.Label sends the network equipment according to concrete FEC, sends MPLS label application request to tag library, then the MPLS label of application just corresponding this concrete FEC.Hence one can see that, and when label sent the network equipment and belongs to different FEC respectively, this label sent network equipment according to different FEC, applies for respectively corresponding those the different FEC of a plurality of different MPLS labels; Promptly label sends the network equipment and can have a plurality of MPLS labels simultaneously, and those a plurality of MPLS labels be by label send the network equipment respectively according to different FEC to the tag library application, so corresponding different respectively FEC of those MPLS labels.
Before step S401, also need the corresponding relation of set handling message identification and process information, determine which process information that will go in the label mapping table is stored in the MPLS label, is provided with the corresponding relation of those process informations and process information sign then.For example: the type of service that needs will go in the label mapping table is stored in the MPLS label, and type of service comprises: common MPLS business, L3VPN (Layer2 Virtual Private Network, two-layer virtual private network) professional, VPWS (Virtual Private WireService, the service of virtual private circuit) business and VPLS (Virtual Private LAN Service, virtual special local area network service) are professional four kinds.Then can represent common MPLS business, L3VPN business, VPWS business and VPLS business with 00,01,10,11 respectively, those 00,01,10,11 are the sign of representing miscellaneous service, those signs are stored in the MPLS label, need take 2 bit space in MPLS label 20 bits.If needing the business information of storage is common MPLS business, then service identification 00 is deposited in the MPLS label; If needing the business information of storage is the L3VPN business, then service identification 01 is deposited in the MPLS label; If needing the business information of storage is the VPWS business, then service identification 10 is deposited in the MPLS label; If needing the business information of storage is the VPLS business, then service identification 11 is deposited in the MPLS label.
Step S402, label send the network equipment this MPLS label are sent to the label reception network equipment, finish the mapping of label.
Label sends the network equipment and arrives the MPLS label to the tag library application, comprises the process information sign in this MPLS label; Then, label sends the network equipment and passes through signaling protocol, the formation label mapping message is bound in the IP address that the MPLS label applied for and this label is sent the network equipment, then this label mapping message is sent to label and receive the network equipment, receive the network equipment by label and store, thereby finish the mapping of MPLS label.
The detailed process of MPLS label application among the above-mentioned steps S401 as shown in Figure 5, may further comprise the steps:
Step S501, label sends the process information that the network equipment is stored as required, and the MPLS label section of carrying out is decomposed.Cun Chu process information is multiple if desired, and the process information kind that then can store is as required carried out multistage with MPLS label correspondence and decomposed.
MPLS label value size is 20 bits, this 20 bit is not used full during actual the use, the maximum label value of supposing the miscellaneous service of MPLS network equipment support is 32K, the then actual label value that uses only need be represented to get final product with 15 bits, and remaining 5 bit reality are not used in the label so.
Therefore, the MPLS label can be divided into the two large divisions, comprise: first and second portion, as shown in Figure 7, first is used for the storage tags deviant, takies 15 bits, and second portion is used for being stored into the section processes information in the label mapping table, those process informations are to be stored in the MPLS label with the form that identifies, and this second portion takies 5 bits.And according to different process information storage demands, also second portion can be proceeded to divide, for example: the label transmission network equipment needs to go into type of service and the formation ID (IDentity in the label mapping table, the identify label number) classification information deposits in the MPLS label, and type of service need take 2 bit space, formation ID classification need take 3 bit space, then the network equipment continues the second portion of MPLS label is divided into two little parts, the space of distributing 2 bits and 3 bits respectively, the space of 2 bits is used for the identification information of storage service type, and the space of 3 bits is used for the identification information of storage queue ID classification.
