It is a challenge to break up the wavelength into smaller sub-wavelength parts for optical network. The sub-wavelength switch (OSS) can be realized employing time and space division multiplexing, and orthogonal frequency division multiplexing among others. In the industry side, automatic switched optical network (ASON) based on synchronous digital hierarchy (SDH) is widely employed in the backbone...
Automatically switched optical network (ASON) is controlled with the help of generalized multi protocol label switch (GMPLS) protocol. It enables telecom operators automatic traffic provisioning for enhanced network protection, operation and maintenance, but the deployed ASON/GMPLS realizes only point-to-point connections. The emerging broadband services, such as IPTV and e-Science, would need point-to-multipoint...
Automatic switched optical network (ASON) is controlled with generalized multi protocol label switch (GMPLS). It enables telecom operators to provide automatic traffic provisioning for enhanced network protection, operation and maintenance. The emerging broadband services, such as IPTV and e-science, need point-to-multipoint and multipoint-to-multipoint connections besides the point-to-point one in...
