Method for estimating the traffic matrix of a communication network

In many packetized communication networks, it is not feasible to obtain exact counts of traffic (OD counts) between specific origin-destination node pairs, because the link counts that are readily obtainable at router interfaces are aggregated indiscriminately over OD pairs. The best that can be done is to make a probabilistic inference concerning the OD counts from the observed link counts. Such an inference relies upon a known linear relationship between observed link counts and unknown OD counts, and a statistical model describing how the values of the OD and link counts are probabilistically distributed. Disclosed is an improved method for making such inferences. The disclosed method takes explicit account of past data when forming a current estimate of the OD counts. As a consequence, behavior that evolves in time is described with improved accuracy and smoothness.

In one embodiment, a counting method of the invention uses an adaptive sketching-update process to compress an unknown cardinality into a counter value that counts the number of binary ones in a hashed bitmap vector.

Parameters of the sketching- update process are selected so that the relative error of cardinality estimates obtained based on the counter values is relatively small and substantially constant over a relatively wide range of cardinalities, e.g., from one to about one million. Due to the latter property, the counting method can advantageously be implemented in the form of embedded software that relies on a relatively small, fixed amount of memory.
