Appeal No. 2004-1703
Application No. 09/333,269
1. A node for use in a data network, said node
comprising:
- an input for receiving traffic units from a
first remote node;
- an output for releasing traffic units to a
second remote node;
- a control unit coupled to said input for
estimating a data occupancy level of at least a portion
of the data network based at least on a rate of traffic
units passing from said input to said output, when the
data occupancy level reaches a certain threshold said
control unit being operative to generate a control
signal instrumental to cause a reduction in the data
occupancy level.
THE REFERENCE
Newman 5,457,687 Oct. 10, 1995
THE REJECTION
Claims 1-24 stand rejected under 35 U.S.C. § 102(b) as being
anticipated by Newman.
OPINION
We reverse the aforementioned rejection.
Each of the appellants’ independent claims requires
estimating a data occupancy level of at least a portion of a data
network based at least on a rate of traffic units passing from an
input to an output of a node. The appellants state that the data
occupancy level is the amount of data being carried by the
transport ring that interconnects the node with other nodes
(specification, page 12, lines 19-20).
