Step 11, determines the carry-on AF(Appointed Forwarders of current fragment message, specifies forwarding person) information and VLAN(Virtual Local Area Network, VLAN) segment information;
Wherein, described AF information is AF information corresponding to VLAN that described VLAN segment information comprises, and that is to say, the VLAN segment information carrying in fragment message is illustrated in the AF information that needs to carry the VLAN that this VLAN segment information comprises in this fragment message.For instance, the AF information of the VLAN here does not refer to the AF information of all VLAN that VLAN fragmented packets that VLAN segment information is corresponding contains, the one or more VLAN that contain for corresponding VLAN fragmented packets do not have the situation of corresponding AF information, in this fragment message, can not carry the AF information that these one or more VLAN are corresponding;
For instance, corresponding AF information can be, but not limited to comprise: AF title and corresponding vlan information; Corresponding VLAN segment information can be, but not limited to comprise: indication information and VLAN range information, described indication information is used to indicate and in fragment message, carries described VLAN range information, described VLAN range information refers to the VLAN ID(VLAN mark of each VLAN that VLAN fragmented packets contains) scope of value, if corresponding VLAN range information can be the VLAN1(VLAN ID value VLAN that is 1) to the VALN1000(VLAN ID value VLAN that is 1000) amount to 1000 VLAN, etc.
Step 12, is carried on described AF information and VLAN segment information in described fragment message and sends, so that receive the AF information that the network equipment of fragment message can be managed the VLAN of its local maintenance according to corresponding AF information and VLAN segment information.
By technique scheme, can carry a large amount of AF information by fragment message on the one hand, can also ensure that on the other hand the receiving terminal of AF information can be processed corresponding AF information accurately, thereby improve the reliability of network.
The embodiment of the present invention also provides a kind of method of specifying forwarding person's information of processing, and its specific implementation can as shown in Figure 2, can comprise the following steps:
Step 21, receives fragment message, obtains AF information and VLAN segment information in described fragment message, and wherein, described AF information is AF information corresponding to VLAN that described VLAN segment information comprises;

Can find out by this technical scheme, owing to not only having sent the AF information of VLAN in AF information transmitting terminal, also send corresponding VLAN segment information, make information receiving end process respectively each fragment message independently and process again without waiting until that all fragment messages collect after standby, thereby ensure the AF information of the VLAN of renewal local maintenance that can be promptly and accurately at information receiving end, effectively improved the performance of Internet Transmission.
For ease of understanding, will realize example taking the present invention below and specifically be applied in TRILL network as example, the specific implementation process of the embodiment of the present invention is described in detail.
In TRILL network, corresponding fragment message is TRILL-Hello burst, is called for short Hello burst.In the time that the embodiment of the present invention is applied in TRILL network, specifically can in each Hello burst, both carry corresponding AF information, also carry the scope(scope of VLAN corresponding to corresponding AF information simultaneously) information, for determining the VLAN segment information of the AF information of carrying in each Hello burst.So just, can make the Appointed Forwarders Sub-TLV(in network be called for short AF information) can in multiple TRILL-Hello bursts (abbreviation fragment message), issue, and can ensure that the RB that receives TRILL-Hello burst can upgrade processing to the AF of corresponding VLAN in time.
In TRILL network, the scope information of the VLAN that corresponding Hello burst carries specifically can be, but not limited to comprise indication information and VLAN range information, wherein:
(1) can use the special Nickname(pet name) as indication information, in this Hello burst, carry VLAN segment information for showing, for example, can be that " 0 " is as corresponding indication information with Nickname field value, the indication information that certainly, also can adopt other specific values to mention as this place;
(2) can use the affiliated VLAN range information of newly-increased AF Scope TLV(AF) carry corresponding VLAN range information, for the VLAN segment information of indicating the AF information of carrying in this Hello burst to belong to.
After constructing in the manner described above corresponding Hello burst and sending, the AF information of carrying in corresponding receiving terminal just can be to each Hello burst is processed independently.For example, non-DRB receives and comprises forwarding person's the appointed information that Appointed Forwarders Sub-TLV(specifies) Hello burst after, can only process the AF situation of change in this VLAN segmentation, only in VLAN segmentation corresponding to this VLAN segment information, basis is received the corresponding AF information of AF information updating local maintenance; Can think that for the AF information that is not included in the VLAN in this VLAN segmentation its AF does not change; Meanwhile, the VLAN that does not specify AF for it in this VLAN segmentation, RB need to remove the own original AF safeguarding.
For ease of understanding, below in conjunction with a concrete example, corresponding RB is received that the processing mode after the Hello burst that comprises Appointed Forwarders Sub-TLV is described.
For example, as shown in Figure 3, supposing to specify is VLAN1,3,5,7 as the RB1 of DRB ..., 99 and VLAN1001,1003 ..., 1099 AF, and to specify RB3 be VLAN2,4,6,8 ..., 98 and VLAN1002,1004 ..., 1100 AF.
Based on the hypothesis shown in above-mentioned Fig. 3, corresponding Hello burst can be, but not limited to comprise content as shown in Figure 4 and Figure 5, wherein:
The content of the burst 1 shown in Fig. 4 comprises: use special Nickname to carry VLAN segment information in this burst of 0 expression, VLAN range information in corresponding VLAN segment information is with the initial VLAN ID of Start.VLAN(value) and End.VLAN(termination VLAN ID value) represent, what in this burst 1, carry is the AF information of the VLAN in VLAN1 to VLAN1000 segmentation; Follow-up content is corresponding AF information, and for example, the AF information of VLAN1 is that DRB(is RB1), the AF information of VLAN2 is RB3, etc.
The content of the burst 2 shown in Fig. 5 comprises: use special Nickname to carry VLAN segment information in this burst of 0 expression, VLAN range information in VLAN segment information represents with Start.VLAN and End.VLAN equally accordingly, and what in this burst 2, carry is the AF information of the VLAN in VLAN ID1001 to 4094 segmentation; Follow-up content is corresponding AF information, and for example, the AF information of VLAN1001 is that DRB(is RB1), the AF information of VLAN1002 is RB3, etc.
In the time that the RB3 in Fig. 3 receives the DRB Hello burst of DRB transmission, its processing mode that can adopt comprises:
In the time that RB3 receives burst 1, himself be set to VLAN2,4,6 ... 98 AF, simultaneously, because the VLAN segment information of specifying at this Hello burst is 1-1000, but in this Hello burst, do not provide the AF information of VLAN100～1000, therefore, RB3 need to remove the AF information of VLAN100～1000 of local maintenance;
In the time that RB3 receives burst 2, himself be set to VLAN1002,1004 ... 1100 AF, simultaneously, because the VLAN segment information of specifying at this Hello burst is 1001-4094, but in this Hello burst, do not provide the AF information of VLAN1101～4094, therefore, RB3 need to remove the AF of VLAN1101～4094.
Alternatively, in this embodiment, cause AF to change for fear of abnormal scenes such as Hello burst loss not processed, cause same VLAN to have multiple AF to occur, complete in the given time a transmit operation for the AF informational needs of all VLAN, the AF information that for example, can make all VLAN is in each Hello Interval(Hello message interval time) in all send once.
In the embodiment of the present invention, the VLAN segmentation of all Hello bursts covers the complete span of VLAN ID, and for example, the complete span of current normal VLAN ID is 1～4094.
Further, in the embodiment of the present invention, if a Hello burst can carry the AF information of all VLAN, also need to show that by corresponding VLAN segment information the AF information of all VLAN carried completely, for example, the span of supposing VLAN ID is 1～4094, in the time that some Hello bursts can carry the AF information of all VLAN, corresponding VLAN segment information can be as shown in Figure 6, be that VLAN range information is 1～4094, to represent that this Hello burst has carried the AF information of all VLAN.
Can find out by foregoing description, above-described embodiment by having carried an Appointed Forwarders Sub-TLV that VLAN segment information is corresponding in a single Hello burst, thereby can effectively ensure that user data (the AF information of VLAN) can be carried in TRILL-Hello burst and normally be forwarded in TRILL territory, and can make TRILL-Hello burst under various application scenarioss correctly to process receiving end, to ensure the reliability of Internet Transmission.
Further, it is even more that the technical scheme that the embodiment of the present invention provides can support that any scene reaches 4k VLAN() the transmission of AF information.And, can delete fast at information receiving end (as RB etc.) AF having lost efficacy, effectively reduce the probability of AF conflict, thereby reduce the time of blocking flow when AF changes, improve network performance.
