TL;DR: This article proposes a novel, spectrum- efficient, and scalable optical transport network architecture called SLICE, which enables sub-wavelength, superwa wavelength, and multiple-rate data traffic accommodation in a highly spectrum-efficient manner, thereby providing a fractional bandwidth service.

TL;DR: A concept of a novel adaptation scheme in SLICE called distance-adaptive spectrum resource allocation, which can save more than 45 percent of required spectrum resources for a 12-node ring network, is presented.

TL;DR: A novel multiflow optical transponder (OTP) that enables more efficient IP optical networking and a novel optical virtual private line service based on multiflow OTPs that supports multiple optical connections from a single customer site to multiple customer sites with capacity adjustment is discussed.

TL;DR: The architecture, enabling technologies, and benefits of elastic and adaptive optical networks with the new concept of an optical corridor are overviewed and some possible study items that are relevant to the future standardization activities are discussed.

TL;DR: In this paper, a bandwidth variable communication method is provided that enables effective use of frequency bandwidths in which the bit rate is constant in every optical path, and exchanging control information between the network management apparatus and a control unit of each communication apparatus on the optical path route.
