Efforts of standardization bodies illustrate that Ethernet is conquering carrier environments. Resulting technologies intend to overcome Ethernet bridging limitations. Validated through emulation, we ...
Wavelength Selective Switches time requirements for shared path protection in ASON/GMPLS rings
Wavelength Switches time shared path protection ASON/GMPLS rings
2008/8/6
We analyze the protection time provided by the shared path protection scheme in GMPLS-based optical rings, as a function of the switching time of the Wavelength Selective Switches (WSS).

Proactive Protection Based on Pre-FEC Statistics in pure IP Networks
Proactive Protection Pre-FEC Statistics pure IP Networks
2008/8/3
We extend the implementation of proactive protection to pure IP protection schemes and test its performance over a real DWDM system and additional failure modes: PMD injection and mechanical disconnec...
WSXC optical networks are an interesting option for future optical transport networks. All competitive future optical transport networks will have some restoration mechanism implemented. In this paper...
Dynamic Protection and Restoration Supporting QoS in OBS/GMPLS Interworking Network
Dynamic Protection Restoration Supporting QoS OBS/GMPLS Interworking Network
2008/7/31
Dynamic protection/restoration schemes supporting QoS were proposed in OBS/GMPLS interworking network for the first time. Dynamic offset time scheme supported by OBS extensions was also verified.
