Abstract
Ethernet is a success story in local area networks (LAN).
Efforts for extending its boundaries beyond LAN to the carriers' backbone
networks are in progress. We study the problem of designing reliable and cost-efficient
high-rate (100Gbit/s) carrier-grade Ethernet in a multiline-rate
optical network under signal transmission-range constraints. Reliability is
achieved using shared-path protection at the connection level (Ethernet tunnel
in this study). We construct an auxiliary graph, called mixed topology (MT),
using which it is possible to: 1) identify traffic grooming possibilities;
2) select a path which requires the minimum amount of 3R regeneration; and
3) effectively choose the data rate of the channel to be established. Our
algorithms, tested on the 17-node German network, resulted in lower network
cost and higher resource utilization compared with other schemes.
