Eng. This paper studies the capacity and flow assignment problem artstng in the design of selfhealzng ATM networks using virtual path (VP) concept. The problem is formulated here as a linear programming problem which is solved using standard methods. The objective is to minimtze the spare capacity cost for the given restoration requirement. The spare cost(More)
In this thesis, we present the identification of methods and tools for the design and analysis of an Agile All-Photonic Network (AAPN). This thesis discusses the layered topology which comprises of a set of overlaid star/tree networks, with an optical core space switch at each of the star centers and hybrid photonic/electronic switches at the edges, and(More)
This paper studies the capacity and flow assignment problem arising in the design of self-healing asynchronous transfer mode (ATM) networks using the virtual path concept. The problem is formulated here as a linear programming problem which is solved using standard methods. The objective is to minimize the spare capacity cost for the given restoration(More)
In this paper, we present an approximate model (with finite or infinite waiting room) for an integrated service system with three types of traffic: a first offered narrow-band traffic, an overflow narrow-band traffic and a wide-band traffic. A narrow-band call requires a single server, while the number of servers required to serve a wide-band call is N .(More)
We study the capacity allocation problem in service overlay networks (SON)s with state-dependent connection routing based on revenue maximization. We formulate the dimensioning problem as one in profit maximization and propose a novel model with several new features. In particular the proposed methodology employs an efficient approximation for state(More)
The Agile All Photonic Network (AAPN) is a high speed transparent agile optical transport network. A key issue in these all photonic networks is the distributed scheduling method employed at the edge nodes and the manner of co-ordination with the core switching state. In this paper we compare several classes of resource sharing methods. Optical Burst(More)
