In this context, the optical burst switching (obs) technology is considered as a promising solution for reducing the gap between transmission and switching speeds in future networks. This thesis presents the analysis, modelling, and evaluation of the obs network with emulated offset-time provisioning (e-obs). E-obs defines an obs network architecture to transport and switch optical data bursts in a core network. On the contrary to a conventional offset-time provisioning obs (c-obs) architecture, where a transmission offset time is introduced in the edge node, in an e-obs network the offset time is provided in the core node by means of an additional fibre delay element. The architecture is motivated by several drawbacks inherent to c-obs architectures. It should be pointed out that the e-obs has not been studied intensively in the literature and this concept has been considered rather occasionally. Due to the limitations in optical processing and queuing, obs networks need a special treatment so that they could solve problems typical of data-centric networks. Contention resolution in optical domain together with quality of service (qos) provisioning for quality demanding services are, among other things, the main designing issues when developing obs networks. Another important aspect is routing problem, which concerns effective balancing of traffic load so that to reduce burst congestion at overloaded links. Accounting for these requirements, the design objectives for the e-obs architecture are (i) feasibility of offset-time provisioning, (ii) an overall high quality of service, and (iii) reduction of network congestion. These objectives are achieved by combining selected concepts and strategies, together with appropriate system design as well as network traffic engineering.
