Table 9
Introduce a kind of concrete implementation step of in the transmission network domain system, determining the going out of Business Stream/ingress edge equipment below again.
In this example, suppose the Business Stream bi-directional symmetrical, system promptly requires to determine the ingress edge equipment of Business Stream on outlet device, also requires to determine on ingress edge the outlet edge equipment of Business Stream.
Step 1, control network element 420 is according to the corresponding relation shown in the table 6, and the stream source/place that the described overseas network address is associated and the corresponding relation of edge device are handed down on the every other relevant edge device.
For example, for edge device A, the control network element is gone into shown in the table 10 for its corresponding relation that issues:
Edge device Stream source/place
B 200.1.3.0/24
C 202.0.0.0/8、210.8.0.0/16
Table 10
Behind control network element 420 newly-increased corresponding relations, the corresponding relation that increases associated stream source/place, the overseas network address and edge device newly is handed down on the every other relevant edge device.
For example, a newly-increased edge device C and overseas network address 210.8.0.0/16 corresponding relation are as shown in table 7 on the control network element 420, then control network element 420 and immediately it are issued edge device A and B, and the corresponding relation of edge device A obtains upgrading as shown in table 11:
Edge device Stream source/place
B 200.1.3.0/24
C 202.0.0.0/8、210.8.0.0/16、210.8.0.0/16
Table 11
In like manner, after control network element 420 is cancelled a corresponding relation, notify the corresponding relation deletion of relevant edge device stream source/place that the overseas network address of being cancelled is associated and edge device.
Step 2 when edge device is handled the Business Stream that flows into transport network domains, as ingress edge equipment, according to the information source place of Business Stream, is determined its outlet edge equipment, as outlet edge equipment, according to the stream source, determines its ingress edge equipment.
For example, when being used as A and receiving Business Stream from 200.1.4.1 to 202.1.1.1 for ingress edge equipment, according to the corresponding relation shown in the table 12, the ingress edge equipment of determining this Business Stream is C.When being used as A and receiving Business Stream from 202.1.1.1 to 200.1.4.1,, determine the ingress edge equipment C of Business Stream according to the corresponding relation shown in the table 12 for ingress edge equipment.
