Method, apparatus and program storage device for efficient construction of network overlays through interconnection topology embedding

摘要

Methods, apparatuses and program storage devices for constructing a network overlay via embedding an interconnection network in a network overlay graph are provided herein. The network delay distances between pairs of overlay nodes are measured on the shortest network paths. The mapping of the interconnection topology to the network overlay nodes preferably involves assigning 2m m-length binary indexes to the network overlay nodes. There is proposed herein a polynomial time algorithm for interconnection topology embedding using iterative cluster division and node binary index assignment. There is further proposed herein a method for construction of network overlays through interconnection network topology embedding, with the objective of optimizing a quality of service metric (e.g. minimization of the average network overlay routing delay).
