In this paper we consider the pricing of point-to-point bandwidth leasing contracts and options. The underlying asset of these contracts is a point-to-point telecommunications connection. Due to the network structure the network capacity prices depend nonlinearly on each other. A leasing contract on a point-to-point connection can be seen as an option because the seller of the connection select...

We will be concerned here with efficiencies of point-to-point and multidrop links. Directly or indirectly, these efficiencies translate to dollars. For instance, a point-to-point link often takes the form of a leased high-quality telephone line, which may be very expensive. In the case of a multidrop link, the line may be owned rather than leased, but if its efficiency is too small, its users w...

Using the category of frames we consider various generalizations of the patch space of a topological space. Some of these constructions are old and some are new. We consider how these variants interact and under what circumstances they agree.
