The Internet is in a transition phase. Migrating to IPv6 is currently the centre of many studies, since the IPv4 address space exhaustion is starting to be noticeable by facts like the slowdown in the growth of the IPv4 routing table. Another less advertised but equally important challenge for the Internet is the exhaustion of the current 16 bit Autonomous System Numbers. The solution adopted by the...
The emergence of wavelength division multiplexing (WDM) technology has led to a tremendous increase in the available transmission capacity in wide area network (WAN). This technology is also being used in backbone networks. For a large-scale network, it is difficult to maintain the centralized global state information of the network. Hence, distributed methods are required to organize network nodes...
Internet traffic is highly dynamic and difficult to predict in current network scenarios. This makes of traffic engineering (TE) a very challenging task for network management and resources optimization. We study the problem of intradomain routing optimization under this traffic uncertainty. Recent works have proposed robust optimization techniques to tackle the problem, conceiving the robust routing...
Network multimedia applications constitute a large part of Internet traffic and present a big challenge because of their sensitivity to delay, packet loss and higher bandwidth requirement. The need for guaranteed delivery and lower delay is caused by propagation of more the one domain. The domains used in this paper are co-operating and communicating with each other and all of them support IPv6 QoS...
In recent years, information leakage through the Internet has become a new social problem. Many information leakage incidents are caused by illegal applications such as Peer-to-Peer (P2P) file sharing software. To prevent information leakage, early detection and blocking of the traffic exchanged by illegal applications is strongly required. We have proposed a method for application identification...
Due to exponential increases in internet traffic, Active Queue Management (AQM) has been heavily studied by numerous researchers. However, little is known about AQM in satellite networks. A microscopic examination on queueing behavior in satellite networks is conducted to identify problems with applying existing AQM methods. A new AQM method is proposed to overcome the problems and it is validated...
Previous simulation studies have shown that providing a simple priority to short-flows in Internet routers can dramatically reduce their mean delay while having little impact on the long-flows which carry the bulk of Internet traffic. In this paper, we present simple fluid models which can be used to quantify this observation. We carry out a connection-level analysis taking into account file arrivals...
Quality of service (QoS) in the Internet depends on queuing and sophisticated scheduling in routers. In this paper, we address the issue of managing traffic flows with different priorities. In our reference model, incoming packets are first classified based on their priority, placed into different queues with different capacities, and then multiplexed onto one router link. The fuzzy nature of the...
