It is of great significance for network operators and researchers to obtain accurate AS-level traceroute paths, for which mapping IP addresses to correct AS numbers is critical. Thus, there have been a lot of efforts to improve the original IP-to-AS mapping table, which was extracted from BGP routing tables. One of these efforts is called pair matching, which refines the original mapping table by...
Multicast is widely applied for multimedia communications in Internet. The effective multicast routing is the key technology to the communications. The Qos of multi-constrained multicast routing problem deserves more attention. The objective function is to minimize the cost and meet multiple constraints to realize high Qos. The solutions' fitness is obtained by the concentration mechanism of immune...
This paper studies the traffic hot spots of mesh networks in the context of chip multiprocessors. To mitigate these effects, this paper describes a non-uniform fat-mesh extension to mesh networks, which are popular for chip multiprocessors. The fat-mesh is inspired by the fat-tree and dedicates additional links for connections with heavy traffic (e.g. near the center) with fewer links for lighter...
