The host-to-host conmunication mode based on the "IP address" has been difficult to meet the current development requirements of the Internet. Research of the future network has become a hot spot, and Information Center Network (ICN) is considered a promising fixture network architecture. ICN can't avoid the emergence of network congestion because of the routing and forwarding based on information...
Traditional Internet based on the IP routing has an innate deficiency when facing up with large numbers of concurrent distribution of video and other media content. Software-Defined Networking (SDN) and OpenFlow protocol try to improve data transfer efficiency and flexibility by separating the forwarding layer and control layer, and the content-based routing idea proposed by Content-Centric Networking...
We propose dynamic routing and spectrum assignment algorithms for bitrate-flexible lightpaths in OFDM-based optical networks. The novel algorithms enable dynamic spectrum assignment with more efficient resource utilization and less traffic blockings.
