“…Thus, the code sequence becomes longer, too. However, as indicated by [13], a core network with 10 In addition, we compared Tables 3 and 4, and discovered that when the number of core switching nodes becomes larger, under the condition that QC and EQC pick up 3-7groups (i.e., passing through 3-7 nodes), the noise margin becomes wider. This means that if the core network gets bigger with more nodes, the noise margin will get wider.…”

The optical label switching has been proposed to simplify the packet forwarding process. These methods simplify the design of switch devices in optical domain and speeds up packet forwarding significantly, but packet transmission requires either header modification or any label swapping techniques. Hence, we would like to take advantage of the existing OCDMA coding schemes to encapsulate the labels, which can achieve the same goal, but of ideal switching avoid the O/E/O procedure. The OCDMA codes (labels) are suitable for expressing routing information. Our methodology doesn't need any label swapping/header modification, so that the upper layer, i.e., the label switching layer, can operate on optical networks transparently.

“…It is not easy to estimate the number of core nodes that will be required in the core MPLS network in the future. However, an investigation of a large number of backbone networks operated by different Internet service providers is given in [9] and it is indicated that 10-30 core nodes are sufficient and a similar number is used in the European ACTS project OPEN [10], which considers an all-optical network based on optical cross connects. Therefore, the focus is on networks with less than 50 nodes in the core network.…”

The MONET [4], AON [5], and ACTS [6] projects have demonstrated that WDM optical networks are feasible. Moreover, there are optical networking vendors like LUCENT [7], CISCO [8], Calient Networks [9], ADVA [10], and others.…”

In recent years, optical transport networks have evolved from interconnected SONET/WDM ring networks to mesh-based optical WDM networks. Time-slot wavelength switching is to aggregate the lower rate traffic at the time-slot level into a wavelength in order to improve bandwidth utilization. With the advancement of fiber-optics technologies, continual increase of fiber bandwidth and number of wavelengths in each fiber, it is possible to divide a wavelength in a fiber into time-slots, and further divide a time-slot into mini-slots so that the fiber bandwidth can be more efficiently utilized. This article proposes a router architecture with an electronic system controller to support optical data transfer at the mini-slot(s) of a time-slot in a wavelength for each hop of a route. The proposed router architecture performs optical circuit switching and does not use any wavelength converter. Each node in the mini-slot TDM WDM optical network consists of the proposed router architecture. Three different network topologies are used to demonstrate the effectiveness and behavior of this type of network in terms of blocking probability and throughput.
