specification, page 1, lines 7-8). The system and method
measures the transmission of a desired cell in a cell stream,
such as a stream of asynchronous transfer mode (ATM) available
bit rate (ABR) user cells, during a selected time interval based
on the occurrence of predetermined events. The measurement is
then used to determine the cell bandwidth (specification at page
5, lines 13-19). The measurement comprises sensing first and
second events, measuring the time period there-between, counting
the number cells received during the time period, and calculating
the transmission rate based on the time period and number of
cells received (specification at page 6, lines 6-21).
Claim 34 is representative of the claimed invention and is
reproduced as follows:
34. A method for determining a transmission rate of a first
type of cell transmitted in a cell stream over an asynchronous
transfer mode (ATM) network connection during an event-based
adaptive time period, the method comprising the steps of:
a) sensing the occurrence of a first predetermined event;
b) sensing the occurrence of a second predetermined event;
c) measuring a time period between the occurrences of the
first and second events;
d) counting a number of cell received from the network
connection during the time period; and
e) calculating an actual transmission rate of the cells
