The energy consumption of backbone networks has become a primary concern for network operators and regulators due to the pervasive deployment of wired backbone networks to meet the requirements of bandwidth-hungry applications. While traditional optimization of IGP link weights has been used in IP based load-balancing operations, in this paper we introduce a novel link weight setting algorithm, the...
Although recent studies show that both topological structures and human dynamics can strongly affect information spreading on social networks, the complicated interplay of the two significant factors has not yet been clearly described. In this work, we find a strong pair wise interaction based on analyzing the weighted network generated by the short message communication dataset within a Chinese tele-communication...
Three-Network Convergence” refers to the way the telecommunications network, the TV broadcasting network, and the Internet converge and develop together, connecting the three networks and sharing their resources in the provisioning of Internet access, TV, and telephone services. A related term “triple play service” refers to the provisioning of the three services over a single broadband connection...
The mapping of the Internet topological structure is indeed of great importance for a better understanding of the network's internal structure, network management, etc. Current explorations still mainly rely on the extensive use of the traceroute tool from a given set of sources to a given set of destinations. However, the deployment of dedicated measurement infrastructures on sources is often quite...
Constructing a router-level topology map of an IPv6 network is important for understanding the internal properties of IPv6 networks, building new applications, network management, etc. However, the well-known topology discovery tool, traceroute6, can only obtain interface-level topology information, which creates a significant problem known as IPv6 alias resolution. Though the inaccuracy and incompleteness...
Recently, the characteristics of traceroute probe have been widely studied in the field of Internet topology discovery, which helps researchers to understand the role of Traceroute tool better, such as sampling bias, marginal utility and so on. In this paper, we study three raw datasets of traceroute probe of different platforms and observe an interesting phenomenon: in the process of one probe, every...
Considerable effort has been spent on collecting all the information of routers by using traceroute-like probes in the router-level topology measurements. This method has been argued to introduce uncontrolled sampling biases on statistical properties of the sample graph and heavy load to the network being measured. In order to improve the quality of the maps induced by the method, researchers are...
With the rapid development of IPv6 network, constructing a router-level topology of IPv6 is helpful for network management, network simulation, protocol design, etc. As same as IPv4, the well-known IPv6 topology discovery tool, traceroute6, also brings an important problem named alias resolution. In this paper, we present one novel heuristic method, called Route Positional Method (RPM), for IPv6 alias...
Internet topology plays a vital role in studying network's internal structure and properties. Currently traceroute-based topology discovery is the main approach to map the network. However, the deployments of probing sources are usually quite costly and complex. Even if the total numbers of sources are the same, the overall coverage of the sampled network may vary significantly for different sources...
An accurate map of the Internet is very important for studying the network??s internal structure and network management. The main approach to map the Internet is to collect information from a set of sources by using traceroute-like probes. In a typical mapping project, active measurement sources are relatively scarce while traceroute destinations are plentiful, which makes the sampled graph quite...
