Slotted WDM rings are considered to implement high-speed all-optical metro networks. The usual approach to transfer variable-size data units, such as IP datagrams, is to segment them into cells, and transfer each cell independently in the WDM ring. This approach entails complexity due to segmentation/reassembly procedures. We investigate in this paper architectures and control strategies to guarantee that all segments of a variable-size packet are sent contiguously on the ring, thereby drastically reducing reassembly complexity. Our proposal is based on register insertion techniques exploiting optical delay lines. A number of schemes are proposed, and compared by means of simulation, showing how performance impairments can be traded with hardware complexity.

“…A large number of WDM networks are based on ring topology since ring structure itself is simple and integrative with SONET/SDH standard [11]. One of the first contributions in protecting WDM ring network is proposed in [12] with the idea of protecting a network with only three nodes that are connected (this actually is path protection of WDM ring network that will be discussed later). Many authors have considered WDM ring architectures with link protection and path protection.…”

“…5.4) is now updated to be 8 units including 5 units on (2-1-3) and 3 units on (2-3). Therefore, A-GSBM requires less backup capacity than that of GSBM which is 10 units with 1 unit on each link (2-4), (4-6), (7)(8)(9)(10)(11)(12); 2 units on link (3-6); 5 units on link (5-7). Finally, for domain D3, there is a slight difference in assigning spare capacity from virtual connections to physical connections.…”

“…Fig. 5.6 shows that virtual link (10)(11)(12) and (8)(9)(10)(11)(12) represents set of multi-physical links which are (10-11-12) and (8-11-12) respectively. This is the reason why we should consider virtual link cost in the optimization problems in order to achieve a result that is more efficient.…”

Multi-Domain Network Design Strategy for Survivable Large-Scale Optical Networks

View full text Add to dashboard Cite

This thesis addresses two main issues of survivable multi-domain large-scale optical networks, namely domain privacy and scalability. In principle, the physical network topology of each domain can be hidden from other domains by using an aggregation model to form a network of virtual domains, thereby satisfying domain privacy requirement. First, we develop an improved aggregation model for p-cycle protection that ensures full protection against all single link failures and is more efficient than existing models. To optimize for the spare capacity requirement, Integer Linear Programming (ILP) formulations are derived. Second, we propose a new approach for multi-domain network design using shared-mesh protection where the backup capacity of intra-domain and inter-domain links can be shared more effectively. The proposed approach also provides a three-step systematic design and optimization, which allows our proposed ILP formulation to resolve larger network problems compared to single-domain network design approach. Several practical network design examples are given to illustrate the effectiveness of our proposed technique with respect to spare capacity requirement and network latency.
