Routing indicator

Abstract: The switching centre of the invention comprises a switch for access to the service (11) and a monitoring point (12) which are connected by a multiplex connection (601). The switch is connected to base-station monitors by first multiplex connections (65) and to the switched public telephone network by second multiplex connections (610) also routing indicator signals relating to a permanent file, to a temporary file and to other switching centres. The switch establishes semi- permanent connections between the multiplex connection (601) connecting it to the monitoring point (12) and, on the one hand, the first multiplex connections (65) for an exchange of indicator signals, and, on the other hand, with the second multiplex connections (610) for an exchange of indicator signals with the permanent and temporary files and the other switching centres.

Abstract: We study a class of robust network design problems motivated by the need to scale core networks to meet increasingly dynamic capacity demands. Past work has focused on designing the network to support all hose matrices (all matrices not exceeding marginal bounds at the nodes). This model may be too conservative if additional information on traffic patterns is available. Another extreme is the fixed demand model, where one designs the network to support peak point-to-point demands. We introduce a capped hose model to explore a broader range of traffic matrices which includes the above two as special cases. It is known that optimal designs for the hose model are always determined by single-hub routing, and for the fixed- demand model are based on shortest-path routing. We shed light on the wider space of capped hose matrices in order to see which traffic models are more shortest path-like as opposed to hub-like. To address the space in between, we use hierarchical multi-hub routing templates, a generalization of hub and tree routing. In particular, we show that by adding peak capacities into the hose model, the single-hub tree-routing template is no longer cost-effective. This initiates the study of a class of robust network design (RND) problems restricted to these templates. Our empirical analysis is based on a heuristic for this new hierarchical RND problem. We also propose that it is possible to define a routing indicator that accounts for the strengths of the marginals and peak demands and use this information to choose the appropriate routing template. We benchmark our approach against other well-known routing templates, using representative carrier networks and a variety of different capped hose traffic demands, parameterized by the relative importance of their marginals as opposed to their point-to-point peak demands.
