Presenter: Antonio Marsico, FBK CREATE-NET, Italy
We propose a novel negotiation scheme for an application-driven relaxation of different requirements in multi-layer networks. Simulative results show that it improves service acceptance while keeping requirements' degradation much lower than applications' worst-case acceptable values.

Application aware multilayer control and optimization of elastic WDM switched optical networks (Th1D.4)
9:30 - 10:00     Invited Submission
Presenter: Ioannis Tomkos, Athens Information Technology Center, Greece
In dynamic networks with diverse application requirements, Software Defined Networking (SDN) principles enable application-aware in-operation planning. EU project ACINO built a network orchestrator as the connecting component between network applications and the underlying network infrastructure.

Access Network Economics: A Total-Cost-of-Ownership Perspective (Th1B.1)
8:30 - 8:45     Contributed Submission
Presenter: Christoph Lange, Deutsche Telekom, Germany
Several fiber-based access solutions are compared regarding TCO and NPV using an analytic framework and real service area data. Fiber-copper and fixed-wireless solutions show improved TCO and NPV efficiency short-term, FTTH in longer-term constellations.

Software Defined 5G Converged Access as a viable Techno-Economic Solution (Th1B.2)
8:45 - 9:00     Contributed Submission
Presenter: Andrea Marotta, University of L'Aquila, Italy
Software Defined Converged Access represents a feasible solution to effectively address 5G traffic demands. This paper proposes an integrated mobile-optical control for wavelength and bandwidth allocation. Evaluations of bandwidth utilization and techno-economic viability are provided.

DBA Capacity Auctions to Enhance Resource Sharing across Virtual Network Operators in Multi-Tenant PONs (Th1B.3)
9:00 - 9:15     Contributed Submission
Presenter: Nima Afraz, CONNECT Center, Trinity College Dublin, Ireland
We propose an economic-robust auction mechanism for multi-tenant PON's capacity sharing that operates within the DBA process. We demonstrate that our mechanism improves PON utilization by providing economic sharing incentives across VNOs and infrastructure providers.

Deep Neural Network Based Dynamic Resource Reallocation of BBU Pools in 5G C-RAN ROADM Networks (Th1B.4)
9:15 - 9:30     Contributed Submission
Presenter: Weiyang Mo, The University of Arizona, United States
An LSTM network is developed to predict BBU pool traffic in 5G C-RAN ROADM networks. 5G throughput improvement and resource savings are observed with resource reallocation by reconfiguring the optical network 30 minutes in advance.

Joint Optimization of BBU Pool Allocation and Selection for C-RAN Networks (Th1B.5)
9:30 - 9:45     Contributed Submission
Presenter: Yao Li, The University of Arizona, United States
BBU pool allocation and selection are jointly optimized for maximizing wireless traffic capacity while minimizing wavelength resource occupation in optical networks. Numerical results show optimal BBU pool locations under different traffic patterns and network capacities.

MixCo: Optimal Cooperative Caching for Mobile Edge Computing in Fiber-Wireless Access Networks (Th1B.6)
9:45 - 10:00     Contributed Submission
Presenter: Ning Wang, Soochow University, China
We consider the optimal content caching problem among Mobile Edge Computing (MEC) servers in a Fiber-Wireless (FiWi) access network, to minimize the average content delivery latency subject to limited storage and computing capacity of each server. An MILP model and a Mix-Cooperative (MixCo) caching strategy are developed for efficient performance.
