CONTROL SYSTEMS FOR CURRENT OPTICAL NETWORKS BASED ON GMPLS PROTOCOL

CONTROL SYSTEMS FOR CURRENT OPTICAL NETWORKS BASED ON GMPLS PROTOCOL

Optical transport systems have evolved in many senses with the pass of years. A first advance can be seen on the transport network, which at the beginning used TDM protocol for transport. PDH was the first used protocol, but due to its equipment complexity was replaced for SDH which gives to the optical network a better management. Later, optical networks use WDM to transport data and its improvement, DWDM is currently used providing to transport networks velocities over 100Gbps.

On the other hand, a new control plane protocol was development, MPLS and its improvement for optical networks GMPLS, which is based on the forwarding of information separated from header IP content and the label swapping between MPLS routers, allowing a faster processing of packets or optical signals over the network, this due to the use of labels on packets which contains its own routing information.
