Optical networks of tomorrow are expected to support the rapid growth of data services such as the broadband access,
including broadband mobile access, storage area networks with long connection times and large transfer capacities, as
well as data center interconnections, requiring ultra-high capacity links. Those services with differing capacities and
patterns will converge in the same optical platform. The standardization bodies have reached an agreement on the format
of the optical 100 Gb/s transmission. However, the large variety of services is likely to generate traffics both below 100
Gb/s as well as exceeding that maximum port speed. In order to address this demand efficiently it is necessary to
consider more flexible methods of traffic allocation. One solution may be provided by a spectrum-sliced elastic optical
path network (SLICE). The aim of SLICE is to efficiently allocate client traffic while performing the necessary
networking functionality directly in the optical domain. Technologies and concepts employed in SLICE enable efficient
utilization of network resources by providing optical paths with bandwidths ranging from 40 Gb/s to over 400 Gb/s.
Basing on the concept of elastic optical path, we discuss the following concepts: path bandwidth flexibly following client
traffic with capacity of 40 to 400Gb/s, grooming and aggregation performed optically: seamless aggregation of optical
paths exceeding the maximum speed of a single port to form a super-wavelength optical path; sharing of resources
through reduction of the overall number of required resources; distance adaptation through reduction of consumed
resources by transmission margin optimization.
This paper describes the evolution of future WDM networks that use multi-wavelengths to realize several network functions.
