Atm Virtual Private Networks for the Internet Data Traac

The eecient utilization and management of bandwidth in broadband networks is of paramount importance since bandwidth costs are likely to dominate network operational costs, especially in the wide area scenario. However, relatively little attention has been given to this issue in developing the current schemes for the transport of Internet data traac over ATM. In this paper we describe a bandwidth allocation and management approach for the transport of Internet traac over ATM that uses Virtual Private Networks, exploits the ABR service and implements bandwidth guarantees. We also address the ef-cient sharing of bandwidth between Internet data traac and other media traac using ATM.
