Technology Development of ASON
At 1996,IETF brought the suggestion of MPLS forward
MPLS protocol can provide the package flow control function
called Traffic Engineering to the data network.
MPLS: Multi-Protocol Label Switch

Technology Development of ASON
Generalized Multi-Protocol Label Switching:
The GMPLS was brought forward by IETF at 2000.
Compared with MPLS, GMPLS has been improved further:
− Generalization of label mapping
− Bidirectional transportation
− Enhanced signaling ability
− Integrated routing ability

SC: Switched connection is a service connection requested by aterminal user (router, for example) and then created in the ASONcontrol plane through signaling.
PC: Permanent connection is a service connection calculatedbeforehand and then created through the NM by issuing a command toNE.
SPC: Soft permanent connection, the connection between the user and
the transmission network is configured directly by the NM. Theconnection within the transmission network is requested by the NM andthen created by the NE’s control plane through signaling.

ASON Protocols
GMPLS (Routing, Signaling, Link Management)
OSPF (routing):
Flood and gather topology for calculating service path
RSVP-TE (signaling):
Establish and then maintain the service path
LMP (link management):
Discover the neighbors and links

Protection and Restoration
Protection: Protection switch. Redundancy resource is reserved to
protect the working traffic in very short time when working channels is
failed;
Restoration: Real time reroute. Routing protocol will recalculate the
service path, then signaling protocol re-build the new LSP to restoreservice.
