abstract = {This paper explores the potential benefits of
programmable networks for telecommunication carriers. It particularly focuses on
using a programmable network to offer a new type of wholesale product by adding
value to the wholesale of pure carriage. By augmenting the wholesale of carriage
with the wholesale of network-based computation, the need for server overlay
deployment to support retail service providers is reduced or eliminated. The
paper develops an efficient algorithm for allocation and management of
computation and transport resources within the network infrastructure. This
algorithm is designed to optimize a large network supporting many retail service
providers and can be used by the wholesaler for the optimal management of scarce
computational and transport resources. The algorithm is based on the Lagrangian
relaxation method and provides error bounds so that the accuracy of the solution
can be ascertained. Numerical results are presented and the benefit of the
optimization for a simple multi-service scenario is assessed.}
