Multi-Service Provisioning and Quality of Service (QoS) Guarantee in Optical Code Switched GMPLS Core Networks
, M.Sc. Thesis Sharif University of Technology ; Salehi, Javad (Supervisor)
Abstract
The growth of the word wide Internet causes to increase the request of subscribers for various applications of multimedia which having different traffic characteristics. In order to provide such applications which generate divers data traffic with different transmission rate and quality of service, we need to design a network supporting multi-rate and multi-quality (multi-service) transmission. In this study we present two schemes to support multi-service transmission in generalized multi-protocol label switched (GMPLS) core networks. In the first scheme we use multi-length variable-weight optical orthogonal codes (MLVW-OOC) as signature sequences of optical code division multiplexing system...

Abstract
In this paper, we present a novel labeling scheme to provide multiservice path switching in a generalized multiprotocol label switching (GMPLS) network. The idea is based on optical code division multiplexing (OCDM) scheme in GMPLS network using multilength variable-weight optical orthogonal codes (MLVW-OOC) as signature sequences. The router architecture of the proposed multiservice GMPLS network is also presented. To provide a requested service, the length and the weight of codes are designed based on the service characteristics. Furthermore, to guarantee the desired service, we propose to limit the number of connections based on the activity coefficient of the connected paths. In order to...

Abstract
In this paper, we propose a new scheme to provide multiservice transmission on generalized multiprotocol label switching (GMPLS) networks using optical code-division multiplexing (OCDM) in each wavelength of a wavelength-division multiplexing system. To provide multiservice transmission in a typical GMPLS network, we propose to classify the fiber bandwidth into a number of waveband and consider the wavelengths of each waveband for a specific class-of-service such that the corresponding codes to be used are designed based on the characteristics of the class-of-service. The traffic behavior of the network is examined using Erlang's model, and the probability density functions (PDF) of the...
