PURPOSE: A link capacity computation methods for designing ip networks with performance guarantees is provided to compute worst-case and optimistic link capacity requirements and to optimize metwork topology and to determine router placement within a network. CONSTITUTION: A method for designing a packet-based communications network, comprising the steps of: computing a pair of link capacity values for each link to be included between nodes in a topology of the packet-based communications network(202), the link capacity values representing an upper bound and a lower bound of a link capacity range based on a set of flow demands, a round trip delay and a link congestion scenario associated with at least one connection requirement(204); and outputting the link capacity values for selection of the value at or within the upper and lower bounds for each link, which substantially satisfies the at least one connection requirements, for specification in the network topology(210).
