, below will be so that the present invention realizes that example is applied particularly in TRILL network as an example, to present invention implementation for ease of understanding
The process that implements of example is described in detail.
In TRILL network, corresponding fragment message is TRILL-Hello bursts, abbreviation Hello bursts.When this hair
When bright embodiment is applied in TRILL network, corresponding AF information specifically can be both carried in each Hello bursts, simultaneously
Also the corresponding VLAN of corresponding AF information scope (scope) information is carried, for determining to carry in each Hello burst
AF information VLAN segment informations.It just can so make the Appointed Forwarders Sub-TLV (abbreviations in network
AF information) it can be issued in multiple TRILL-Hello bursts (abbreviation fragment message), it is possible to guarantee receives TRILL-
The RB of Hello bursts can be updated processing to corresponding VLAN AF in time.
In TRILL network, the scope information for the VLAN that corresponding Hello bursts are carried specifically can be, but not limited to bag
Configured information and VLAN range informations are included, wherein：
(1) special Nickname (pet name) can be used as configured information, for showing to take in this Hello bursts
With VLAN segment informations, for example, can with Nickname field values be " 0 " as corresponding configured information, it is of course also possible to
The configured information referred to using other specific values as the place；
(2) newly-increased AF Scope TLV (the VLAN range informations belonging to AF) can be used to carry corresponding VLAN scopes letter
Breath, for indicating the VLAN segment informations belonging to the AF information carried in this Hello bursts.
, then just can be to each in corresponding receiving terminal after constructing corresponding Hello bursts in the manner described above and sending
The AF information carried in Hello bursts is independently handled.For example, non-DRB is received comprising Appointed
After Forwarders Sub-TLV (specify information for turning originator specified) Hello bursts, then can only it handle in this VLAN
AF situations of change in segmentation, i.e., it is only local according to AF information updatings are received in the corresponding VLAN segmentations of the VLAN segment informations
The corresponding AF information safeguarded；The AF information of VLAN for being not comprised in VLAN segmentations then can consider that its AF does not have
Change；Meanwhile, that in VLAN segmentations is not the VLAN that it specifies AF, then RB needs to remove the AF oneself safeguarded originally.
For ease of understanding, corresponding RB is received comprising Appointed below in conjunction with a specific example
Processing mode after Forwarders Sub-TLV Hello bursts is described.
For example, as shown in Figure 3, it is assumed that specify as DRB RB1 be VLAN1,3,5,7 ... ..., 99 and VLAN1001,
1003 ... ..., 1099 AF, and RB3 is specified for VLAN2,4,6,8 ... ..., 98 and VLAN1002,1004 ... ..., 1100
AF。
Based on shown in above-mentioned Fig. 3 it is assumed that then corresponding Hello bursts can be, but not limited to include as shown in Figure 4 and Figure 5
Content, wherein：
The content of burst 1 shown in Fig. 4 includes：Represent to carry VLAN in the burst for 0 using special Nickname
VLAN range informations in segment information, corresponding VLAN segment informations then with Start.VLAN (starting VLAN ID values) and
End.VLAN (terminate VLAN ID values) represents, i.e., what is carried in the burst 1 is VLAN 1 to VLAN 1000 segmentations
VLAN AF information；Follow-up content is then corresponding AF information, for example, VLAN1 AF information is DRB (i.e. RB1), VLAN2
AF information for RB3, etc..
The content of burst 2 shown in Fig. 5 includes：Represent to carry VLAN in the burst for 0 using special Nickname
VLAN range informations in segment information, corresponding VLAN segment informations then equally carry out table with Start.VLAN and End.VLAN
Show, i.e., what is carried in the burst 2 is the AF information of the VLAN during VLAN ID1001 to 4094 are segmented；Follow-up content is then phase
The AF information answered, for example, VLAN1001 AF information is DRB (i.e. RB1), VLAN1002 AF information is RB3, etc..
When the RB3 in Fig. 3 receives the DRB Hello bursts of DRB transmissions, then its processing mode that can be used includes：
When RB3 receives burst 1, then its own is set to the AF of VLAN2,4,6 ... 98, simultaneously as in the Hello
The VLAN segment informations that burst is specified are 1-1000, but do not provide in the Hello bursts AF information of VLAN100~1000,
Therefore, RB3 needs to remove the AF information of VLAN100~1000 of local maintenance；
When RB3 receives burst 2, then its own is set to VLAN1002,1004 ... 1100 AF, simultaneously as
The VLAN segment informations that the Hello bursts are specified are 1001-4094, but do not provide in the Hello bursts VLAN1101~
4094 AF information, therefore, RB3 need to remove the AF of VLAN1101~4094.
Alternatively, in this embodiment, in order to avoid the abnormal scene such as Hello bursts loss causes AF changes not located
Reason, causes same VLAN to have multiple AF to occur, and the AF information for all VLAN needs to complete once to send out in the given time
Operation is sent, for example, all VLAN AF information can be made complete in each Hello Interval (hello packet interval time)
Portion is sent once.
In the embodiment of the present invention, the VLAN segmentation covering VLAN ID of all Hello bursts complete span, example
Such as, current normal VLAN ID complete span is 1~4094.
Further, in the embodiment of the present invention, if a Hello burst can carry all VLAN AF information,
Need to show that all VLAN AF information has been carried completely by corresponding VLAN segment informations, for example, it is assumed that VLAN ID's takes
It is 1~4094 to be worth scope, then when some Hello burst can carry all VLAN AF information, corresponding VLAN segmentations
Information can be using as shown in fig. 6, i.e. VLAN range informations is 1~4094, to represent that the Hello bursts have carried all VLAN's
AF information.
By foregoing description as can be seen that above-described embodiment in a single Hello burst by carrying one
The corresponding Appointed Forwarders Sub-TLV of VLAN segment informations, so as to which user data has been effectively ensured
(VLAN AF information) can be carried in TRILL-Hello bursts in TRILL domains and normally be forwarded, it is possible to so that
Under various application scenarios TRILL-Hello bursts can receiving end correctly handle, to ensure the reliability of network transmission.
Further, technical scheme provided in an embodiment of the present invention can support up to 4k VLAN of any scene (even
It is more) AF information transmission.Moreover, can quickly delete the AF failed in information receiving end (such as RB), effectively subtract
The probability of few AF conflicts, so as to reduce the time of blocking traffic when AF changes, improves network performance.
