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.
A Path Computation Element (PCE) is a computing device in a network capable of calculating paths. Once a PCE receives a path computation request, the PCE is suppose to provide a response within a reasonable short time. However, computing a feasible path is not a straightforward task, since the computational problem must consider several constraints in a short time. In this paper we propose an algorithm...
Today's backbone communication networks serve a wide range of services with different availability requirements. Each customer has a contract, denoted a Service Level Agreement (SLA) which specifies the availability requirement over the contract period. In the literature, different provisioning strategies to establish connection arrangements capable of meeting a statistical asymptotic availability...
At present there is a strong worldwide push toward bringing fiber closer to individual homes and businesses. Another evolutionary step is the cost-effective all-optical integration of fiber-based access and metro networks. STARGATE (IEEE Commun. Mag., vol. 45, no. 5, pp. 50-56, May 2007) is an all-optical access-metro architecture that does not rely on costly active devices, e.g., optical cross connects...
In this work we develop a fair resource allocation scheme for a multi-class time-slotted optical overlapped code- division multiple-access (OV-CDMA) network. The resource management scheme is fair in the sense that the users have their power and rate allotted according to their quality of service (QoS) requirements. In addition, no class of users can dominate over the other classes. A unified framework...
Translucent WDM networks use a set of sparsely but strategically placed 2R or/and 3R regenerators to overcome physical impairments and wavelength collision introduced by fully transparent networks. In this paper, we concentrate on the study of control architectures and management approaches for connection establishment in translucent networks. A hybrid OCP (optical control plane) has been proposed,...
We propose path computation algorithms for two resource allocation models for optical VPN, namely shared and dedicated. By simulation, we show that combined with proposed algorithm, dedicated model can achieve better resource usage efficiency.
