Service Gateway
Action:
Is configured by Gateway selection.
Check the frames into/out of my network.
Judge whether the frame belong to this device.
With this function entity, so that:
Make the function entities in DAS sublayer clearer and more understandable without importing complexity. Leave the Frame Collector and Dstributor unchanged AFAP.In 802.1AX, Frame collector is forbidden to transmit frame to Frame distributor. The rule should not be violated in DRNI.Only Service Gateway need to know to which Intra-das link the frame transmitted.Slide4
Virutal Aggregator Multiplexer
Action:
Is created according to the aggregated links information from other nodes by DLIC.
Forward the traffic to other node in the same portal
Purpose:
For every device in the portal, their aggregator looks like to be same. It’s also a consistent with the Figure 7-2 in D0.3
Distributor can see all the aggregation links, so that link selection negotiation is getting easier.We should not aggregate the Intra-das link into DLAG directly.Slide5
DLAG Internal Coordination
Separate from LACP entity as a new function entity.
Reason:
Information need to coordinate is different with LACP’s
We can’t aggregate the intra-das link into DLAG. Otherwise, may need to change the LACP a lot?
LACP in DRNI is network to network, while DLIC in Portal is within my network.
LACPDU is transmitted on every aggregated links, while DLICPDU is transmitted only on Intra-das link. Slide6
