Abstract:
With the open and standard programmatic interface and the flexibility
of controlling network, Software Defined Network (SDN) can obviously
simplify and integrate operation and business support systems. As a
consequence, to satisfy the rising switching demand in the data
center network, it is a good option to adopt SDN technology. In
addition, current architecture of data center network is far from
ideality, which results in the low utilization rate in bandwidth
resource. For example, mice flow cannot be well effectively served in
the conventional Wavelength Division Multiplexing (WDM) optical
network with at least 50GHz spectrum interval. From a data center
network perspective, it is necessary to further improve the resource
utilization efficiency and the flexibility of coping with different
traffic.
This document described an optical data center interconnect, which
comprises both the fixed and flexible grid transceivers. A traffic
monitor is implemented in the SDN-based data center network to
evaluate the coming traffic demands and allocate appropriate spectrum
for the request. For instance, mice flow can be served by fixed grid
transceivers, well the elephant flows can be transmitted by the
flexi-grid transceiver using multiple subcarriers to form a
superchannel. Thus, spectrum efficiency is optimized and bandwidth
utilization is improved dramatically.
