Efficient Network Switching Hierarchy
Overview In this paper, it is argued that the right granularity for grooming in the next-generation core optical network is STS-48 (2.5 Gbps), while STS-1 (51.8 Mbps) grooming is better suited for the edge of the network and legacy applications. In the TDM world, both wideband (VT1.5 - 1.5 Mbps) and broadband (STS-1 - 51.8 Mbps) grooming are required in particular segments of the network to manage different traffic levels - serving distinct but complementary roles in the network. Similarly, as transport speeds move primarily to 10 Gbps and eventually scale to 40 Gbps, and DWDM channel counts continue to increase, STS-1 and STS-48 grooming switches are also expected to perform distinct but complementary roles at the network edge and core, respectively.
