Abstract:
N-GREEN is a cost attractive optical network, which uses coloured optical packets. Its basic component is a ring of novel overdimensioned switch/router nodes, which promises low latency making it interesting for applications with strict latency requirements like 5G. Nevertheless, it suffers from a low efficiency of resources usage, especially when it is used in the Unicast mode popular in the metro aggregation. Here, we try to ensure a better use of network resources by proposing an alternate packet management and transmission method referred to as Ssh-time which could be used in both the Unicast mode and the Broadcast-and-Select (BS) one. We show by simulation, that the proposed method improves not only the resources efficiency in case of a metro-aggregation network but also decreases the mean access delay.
