BACKGROUND
The invention relates to acknowledgment of receipt of messages in network
protocols. Claim 1 is reproduced below.
1. A method for acknowledgment of receipt of a message in a network, the
network including a plurality of nodes, comprising the steps of:
(a) sending a message from a first node of the plurality of nodes destined
for a second node of the plurality of nodes;
(b) setting a timer for the first node for receipt of an acknowledgment
packet from the second node;
(c) determining if a wait acknowledge packet is received by the first node,
wherein the wait acknowledge packet notifies the first node that the message
has been sent to a next hop; and
(d) resetting the timer if the wait acknowledge packet is received by the
first node.
The examiner relies on the following references:
Chen et al. (Chen) 4,970,714 Nov. 13, 1990

Claims 1-15 stand rejected under 35 U.S.C. § 103 as being unpatentable over
Chen and Ohsawa.
