Appeal No. 2004-1676
Application 09/263,918
BACKGROUND
The invention relates to segmenting and reassembling
asynchronous transfer mode (ATM) data in an ATM interface. In
the past, segmentation and reassembly (SAR) was implemented on
personal computer using a chip, which had the disadvantages of
cost and limited flexibility. The invention implements SAR
functions in software executed on a central processing unit
(CPU), in particular, the CPU of a personal computer.
Claim 1 is reproduced below.
1. A method comprising:
performing asynchronous transfer mode (ATM) segmentation
functions with a segmentation and reassembly (SAR) software
module implemented in a central processing unit (CPU) of a
personal computer including,
receiving data to send;
segmenting the data to generate a plurality of ATM cells;
buffering the plurality of ATM cells in a memory device;
traffic shaping the buffered plurality of ATM cells; and
transmitting the plurality of ATM cells on a network.
THE REFERENCE
The examiner relies on the following reference:
Kwak 6,262,995 July 17, 2001
THE REJECTION
Claims 1, 4, 5, and 7-16 stand rejected under 35 U.S.C.
