With new optical transport systems able to provide sub-wavelength granularity, the dynamic characteristics of the network are expected to strongly increase. Furthermore, such properties are highly related to the underlying physical network topology, which in turn require from the control plane important features such as scalability, dynamism and automatism. In this paper we analyze the properties...
Network load balancing is the ability to aggregate two or more wide area network (WAN) connections in order to achieve greater reliability and overall throughput. This paper discusses traffic technology and flow optimization in optical network. Performance optimization of networks is actually a control problem. Traffic engineering should provide sufficient control in an adaptive feedback control system...
Survivability becomes an important issue in optical networks due to the huge bandwidth offered by optical technology. Many works have studied network survivability. The majority of these works are typically destined to single-domain. In this work we address the survivability in multidomain optical networks. This paper provides a classification of the existing protection solutions proposed for multi-domain...
Optical burst switching (OBS) was proposed as an alternative optical switching paradigm, in order to overcome the limitations of optical circuit and optical packet switching paradigms. In OBS networks, resource reservation protocol plays a key role for better resource allocation along the path from source to destination data transmission. In this paper, we focus and consider some of the relevant one-way...
Resource utilization is an important issue that needs to be taken into account when providing recovery mechanism in networks. In this paper, we investigate the recovery scheme for multi-layer network which cannot only manage the operation confusion among each layer, but also reserve network resources effectively. Then, we proposed an algorithm that adapts the concept of multi-layer approach to multicast...
Protection and restoration strategies are critical to Optical mesh networks. Two are the most usual methods of the optical path protection. In the first method, the spare capacity is usually allocated as a "dedicated" resource where the backup capacity is allocated for the sole use of the connection or link. In the second method, it is associated as a "shared" resource, where the...
Optical packet switching (OPS) technologies are among the most promising solutions for next generation network architectures. Resource contention resolution and Quality of Service (QoS) management mechanisms have been developed in order to remedy the lack of optical buffering and implement multi-service support in OPS networks. In this paper we propose an analytical model for the access and core nodes...
Traffic grooming techniques in optical networks are attracting increasing research attention in order to handle the huge bandwidth mismatch between high capacity lightpaths and low-rate individual traffic requests. It is important to have guaranteed survivability of all user connections in such networks. Path protection has emerged as a widely accepted technique for survivable WDM network design....
The Automatically Switched Optical Networks (ASONs) and the Generalized Multi Protocol Label Switching (GMPLS) control plane are envisaged to play an important role in the next generation Internet. They provide optical networks with intelligence and automation and they enable the Multilayer Traffic Engineering (MTE) paradigm which facilitates the IP/optical adaptive integrated routing. This paper...
