We investigate the problem of omputing the types of the relationships between Internet Autonomous Systems. We refer to the model introdu ed in [6, 17℄ that bases the dis overy of su h relationships on the analysis of the AS paths extra ted from the BGP routing tables. We hara terize the time omplexity of the above problem, showing both NPompleteness results and eÆ ient algorithms for solving sp...

An upward embedding of an embedded planar graph states, for ea h vertex v, whi h edges are in ident to v \above" or \below" and, in turn, indu es an upward orientation of the edges. In this paper we hara terize the set of all upward embeddings and orientations of a plane graph by using a simple ow model. We take advantage of su h a ow model to ompute upward orientations with the minimum number ...
