Abstract
This paper considers the link capacity requirement for an LEO satellite constellation. We model the constellation as an N # N mesh-torus topology under a uniform all-to-all tra#c model. Both primary capacity and spare capacity for recovering from a link or node failure are examined. In both cases, we use a method of `cuts on a graph' to obtain lower bounds on capacity requirements and subsequently find algorithms for routing and failure recovery that meet these bounds. Finally, we quantify the benefits of path-based restoration over that of link-based restoration; specifically, we find that the spare capacity requirement for a link-based restoration scheme is nearly N times that for a path-based scheme.
