Field-trial demonstration of cost efficient sub-wavelength service through integrated packet/circuit hybrid network [Invited]
Carriers are under constant pressure to meet
the ever-increasing bandwidth demand while reducing
cost per bit, enhancing network throughput, and offering
a large variety of services. Hybrid packet and circuit network
technologies are being widely investigated and considered
as a solution for offering both the high network
throughput of the packet domain and wavelength services,
i.e., a low fixed latency and zero packet loss. To enable carriers
to serve a higher number of customers requiring
wavelength services, optical transport network (OTN)-
based sub-wavelength switching is adopted to support
finer granularity with similar performance to full wavelength
services. However, OTN is not able to perform
statistical multiplexing and achieve the throughput
efficiency of packet networks. In this work an integrated
hybrid optical network field-trial is described to demonstrate
the ability to both aggregate and transport sub-wavelength
circuits, and offer high throughput efficiency by
statistically multiplexing traffic on transport wavelengths.
Results show the transport of sub-wavelength services with
packet-delay variation limited to only 15 ns and 82.4%
wavelength utilization using statistical multiplexing
