BoD Service Setup Through GMPLS Call
I want an ETH BoD service !
Hi, I can support the service with the following
possible options……, what would you prefer to?
Hi, somebody call an ETH BoDservice with you !
That’s OK! OK, I prefer to the following option……!
Connections setup
Hi, ETH BOD service is OK!

Bandwidth Decreasing Procedure
GE Link GE Link
TDM Network
I don’t need XXX bandwidth anymore, and xxx bandwidth
is enough now!
Hi, I will delete connection A! Hi, the bandwidth
will be decreased to xxx !
That’s OK!
OK, do it !Connection
remove
Hi, I will charge you at xxx bandwidth!
Remove the member connection from
VCAT group
Remove the member
connection from VCAT group

Bandwidth Increasing Procedure
GE Link GE Link
TDM Network
I need xxx more bandwidth, is it OK?
Hi, I will setup connection A and
B and will add them to the VCG. Hi, xxx more
bandwidth will be added to the
service !
That’s OK!
OK, do it !New connections
setup
Hi, I will charge you more for new
bandwidth!
Add the new connection A and B to
the VCG
Add the new connection A and B to the
VCG

Impact To Existing Protocol
GMPLS SignalingØ GMPLS Call- RFC4974 have already supported the negotiation procedure
Ø The negotiation parameter need be enriched.
• Possible mapping and adaptation path sets
GMPLS Routing
Ø If VCG members are co-routed, the differential delay of different member can be ignored, so the routing protocol is not necessary to extended.
Ø If VCG members are diversy-routed, the differential delay of different member should not be ignored, the routing protocol should concern the link and node delay for path calculation.
