The optical network management system is very important for optical equipment monitoring and managing, the timeliness and accuracy are very critical parameters. Automatic discovery of network nodes is the embodiment of automation of network management system. However, most of the traditional automatic discovery method is based on the ICMP protocol, which is to ping all the IP addresses in local area...
We consider the schemes that would lead to the increase in the channel capacity of free space optical links (FSO) and propose a novel orthogonal angular momentum (OAM)- and WDM-based MIMO architecture for highspeed QKD in turbulent FSO channels. We evaluated the dependence of OAM-based interference, which notably affects QBER, from the number of OAM states and the turbulence strength. The scheme is...
In this paper, we investigate the performance of free space optical (FSO) systems with parallel multihop relaying and path selection. Specifically, we consider an FSO communication system which employs M parallel relaying paths each of which consists of N decode-and-forward relays. We assume the deployment of the so-called mth best path selection (m-BPS) protocol. In this protocol, data is transmitted...
Current GMPLS standardization allows control plane deployment to be either physically or only logically separated from the data plane, describing out-of-fiber or in-fiber control plane configurations. It is widely accepted, that the out-of-fiber strategy provides enhanced flexibility, which derives from the natural separation of both planes. Nonetheless, such a configuration poses new challenges to...
This paper describes a new path computation model in Multi-protocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks. It introduces a path computation element (PCE), which is functionally separate from label switching routers (LSRs). The Path Computation Element (PCE) is an entity that is capable of computing a network path or route based on a network graph, and applying computational...
