With the continuing growth in the amount of backbone traffic, improving the cost-effectiveness and ensuring survivability of the underlying optical networks are very important problems facing network service providers today. In this paper, we propose a bandwidth squeezed restoration (BSR) scheme in our recently proposed spectrum-sliced elastic optical path network (SLICE). The proposed BSR takes advantage...
This paper proposes a joint storage-network resource management for a super high-definition video delivery service. The method for allocating storage and optical path resources is discussed. The feasibility of the proposed system is shown.
This paper investigates power-aware traffic engineering for multi-layer networks utilizing ILP, and proposes a heuristic approach. Simulation results illustrate that partial deployment of TDM-XCs in multi-layer networks with smart traffic engineering contributes to power conservation.
We demonstrate dynamic optical path operation of colorless ROADM and connection switching between routers in a router network. We also evaluate and demonstrate both colorless-directed ROADM and colorless-directionless ROADM in a router network.
A technique to design signaling and management communication networks (SCN and MCN) is proposed based on experiments using a GMPLS-enabled network. This design technique will provide SCNs and MCNs with a sufficient bandwidth for packet loss-free and jitter-less transmission.
