Title:
A CONNECTION PERFORMANCE OPTIMIZE METHOD OF THE ADAPTIVE OPTICAL TRANSMISSION NETWORK AND DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2007/121651
Kind Code:
A1
Abstract:
An adaptive performance optimize device of the optical switch network and method thereof,
when the connection is set up, it can forecast the transmission performance, and
the device includes: a route controller for selecting the route and transmitting the
link information, a link analyzer for analyzing the transmission performance and
the optical characteristic of the received link information in order to determine the
validity of the route, and a connection controller for setting up the connection with
the above effective route. The method includes: selecting the route in answer to
the connection request information and transmitting the link information, analyzing
the transmission performance and the optical characteristic of the above link
information in order to determine the validity of the route, and setting up the
connection with the effective route. Compared with the prior art, because the
said device and method of the present invention forecast the transmission performance
when the new connection is set up, it gains the advancement in the course of the
re-route and setting up the connection, and improves the validity of re-route
and connection of the network, and ensures the high quality signal transmission
in the connection being set up.
