Abstract:
1. A method for provisioning service in a network comprising a first service node, the method comprising: receiving a flow record, at the first service node, from a router comprising a fixed-size buffer, the flow record based on a sampling of packets at the router; automatically determining a measurement interval based on a first traffic load of the first service node; generating a first partial traffic matrix based on the flow record received from the router during the measurement interval, wherein generating the first partial traffic matrix comprises estimating a value of a first matrix element based on stored values of previous partial traffic matrices generated during prior instances of the measurement interval, the first matrix element corresponding to a second traffic load associated with the router; and transmitting the first partial traffic matrix to a matrix generator node to be combined with a second partial traffic matrix generated by a second service node to form a total traffic matrix.
