    Abstract: A method is described for solving traffic engineering problems in a network In one aspect, the invention is used in a network that has at least one QoS service class and at least one class of service that is not a QoS class. Bandwidth is allocated to service routes in the QoS service class so as to optimize a figure of merit such as network revenue. Then a new allocation is made so as to minimize network usage without departing too far from the optimal value of the figure of merit. A residual network consists of that bandwidth that remains unallocated, on each link of the network.
    Bandwidth for non-QoS traffic is allocated to routes on the residual network. In a second aspect, the invention involves the use of optimization techniques to allocate bandwidth among service routes in one or more service classes in response to a set of demands in each class. The demands are calculated so as to take into account an effective bandwidth associated with the pertinent class, and so as to make allowance for the stochastic behavior of the traffic demands that occur in practice.

    Abstract: A method shares resources associated with various classes among calls in the various classes according to a state dependent reservation parameter. Nominal amounts of one or more resources are allocated to each call class. When a call of a class of service operating in a network requires resources in excess of those allocated to the class, resources allocated to other classes of service are advantageously shared with the class of service. The sharing is based on a reservation parameter associated with the class of service of the call. The reservation parameter is advantageously a function of the network state. The role of the reservation parameter is to protect underloaded classes (i.e., those classes not using all of their allocated nominal capacity) from excessive borrowing by overloaded classes ( i . e ., classes using more than their allocated nominal capacity). More generally, the inventive method is used to determine if sufficient resources are available for routing calls and to route calls based on the determined available resources.
