Abstract


The continuous growth of IP traffic in combination with other emerging high rate applications, such as high definition TV, video on demand, cloud computing and grid applications require more scalable and cost-effective networking infrastructure. To cope with this ever increasing bandwidth demand, we are moving towards more sophisticated communication systems, advanced modulation schemes, resources flexibility and more intelligent devices. While moving toward more agile networks flexible resources have clear edge on static resources in terms of reconfigure ability without manual intervention but this solution is not cost effective though. However high cost of flexible and intelligent resources has drawn attention toward hybrid environment where flexible resources join already existing infrastructure to meet bandwidth demands. This study is supported by simulative results derived from a sample optical network. The results give an insight of the spectrum resources utilization and efficiency benefits that can be obtained using hybrid transponder schemes in optical networks.
