IEEE 39- Storage Area Networks Extension Scenarios in a Wide Area WDM Mesh Architecture under Heterogeneous Traffic


ABSTRACT-



In this paper, two storage area networks (SANs) extension scenarios are proposed in a wide area wavelength
division multiplexing (WDM) mesh architecture. While in the first scenario storage resources are assumed to be
located in two nodes serving as primary and secondary SANs, storage resources are assumed to be distributed
over a number of nodes serving as primary and secondary SANs in the second scenario. SAN traffic is assumed
to co-exist with IP and/or 10GE traffic to achieve economy of scale. A hybrid optical switching (HOS) technique
is considered. OCS is used for IP/10GE traffic transmission and OBS is used for SAN traffic transmission.
Simulation is carried out to evaluate the performance of the proposed scenarios using accurate traffic sources.
