Advances in device technology and dense wavelength division multiplexing have enabled modern optical backbones to provide high data rate services in a cost-effective manner. At the same time, applications are emerging with the potential to leverage these capabilities for short time spans: load migration for Internet clouds, integrated computational grids, and remote surgery. Until such applications...
In mobile ad hoc networks, node's free movement is one of the most outstanding features. Due to mobility, link failure happens frequently so several communication problems such as low successful packet delivery ratio and large control overhead are naturally brought. However, node's mobility may bring dynamic situation, for example, distance between source and destination becomes closer or mobile node...
In mobile ad hoc networks, transmission is a challenging problem, because the wireless channel is characterized by limited bandwidth, multi-hop connectivity, and dynamically varying network topology. Compared with unipath routing protocols, multipath routing is an attractive alternative for route resilience and throughput, however, existing multipath routing protocols have problems, such as no concern...
Network management and security is currently one of the most vibrant research areas, among which, research on detecting and identifying anomalies has attracted a lot of interest. Researchers are still struggling to find an effective and lightweight method for anomaly detection purpose. In this paper, we propose a simple, robust method that detects network anomalous traffic data based on flow monitoring...
There have been a lot of research and investigation to improve handover latency of mobile IPv6 (MIPv6). The handover latency is one of the most important factors because performance of TCP flows as well as realtime traffic degrades sharply as the latency increases. The MIPv6 handover process consists of movement detection, duplicate address detection (DAD), and binding update. Among the three components,...
In this paper, we will survey and classify researching advanced routing algorithms that take advantages of MPLS (multiprotocol label switch) network to extent routing algorithms, supporting QoS (quality of service) services and traffic engineering and load balancing. We also consider some recent projects that are researching and working with advanced routing algorithms. This paper include 6 parts...
Routers determine a routing path considering network topology and link state information for guaranteeing quality of service (QoS). Therefore, it is important that routers should know link state information so as to calculate a routing path. However, if routers generate link state update messages inordinately, their router performance may be reduced due to the processing burden of link state update...
Survivability becomes increasingly critical in managing high-speed networks as data traffic continues to grow in both size and importance. In addition, the impact of failures is exacerbated by the higher data rates available in optical networks. It is therefore imperative to address network survivability in an efficient manner in order to design and operate reliable networks. Transparent optical networks...
Overlay multicast has been recently proposed as alternative scheme to traditional IP multicast. However, since data packets are transmitted by relaying between group members in a form of unicast packet, overlay multicast has larger link stress that indicates the number of times that the same data traverses a particular physical link than IP multicast. Larger link stress may cause packet loss by network...
Traffic measurement is required to protect network from abnormal traffic that is created by attacking or computer virus. Traffic measurement and flow information exporting method have being standardized and partially introduced. But traffic measurement devices and flow exporting software have still too low performance to collect all flows. Recently, traffic grows rapidly and various flow by emerging...
The current Internet protocol (IP)-based networks face tremendous requirements such as quality of service (QoS) guarantees, efficient traffic engineering (TE), network scalability, and high network performance, in accordance with the emergence of diverse Internet services. A constraint-based routing path is determined based on network topology and link state information to guarantee QoS. It is necessary...
The advanced information technology (IT) will promote the transformation of communities the world over into an information society and a knowledge-based economy in the next generation. During the past years, the explosive growth of the Internet's popularity has brought a great number of changes in the telecommunications area. The current Internet Protocol (IP)-based networks face tremendous requirements...
