Abstract

Future bandwidth-consuming services will require 10 Tbps class network interface. Massively parallel transmission with dynamic bandwidth assignment becomes a key. To realize the 10 Tbps class dynamic bandwidth flexible media access control (MAC) mechanism, we have proposed “Dynamic MAC” concept. The key technical component is round-robin distribution of the MAC signal into parallel transmission lanes. Therefore, we have proposed a hierarchical round-robin mapper (HRRM) and developed a software-based dynamic MAC emulator for evaluating the HRRM. Details of the emulator and experiment results are presented.
