Appeal No. 94-4400
Application 07/771,063
This is a decision on the appeal under 35 U.S.C. § 134
from the examiner's rejection of claims 10-20, which constitute
all the claims remaining in the application.
The claimed invention pertains to a method for handling
requests on a network between several client nodes and at least a
pair of control point nodes. At any point in time, one control
point node acts as the primary control point node while the other
control point node acts as an alternate control point node.
Representative claim 10 is reproduced as follows:
10. In a network having a client node and a pair of control
point nodes operable as servers to the client node, each control
point node functioning as either a primary control point node or
an alternate control point node, a method for establishing one of
the control point nodes as a primary control point node to the
client node, comprising the steps of:
(a) interrogating each control point node from the client node to
determine its status as a primary or alternate control point
node; and
(b) at each control point node, in response to being interrogated
by the client node:
(1) if the node is a primary control point node, advising the
client node of the status of the control point node as a primary
control point node;
(2) if the node is an alternate control point node, interrogating
the other control point node for information regarding its status
as a primary or alternate control point node;
(3) in response to the receipt of status information indicating
that the other control point node is a primary control point
node, advising the client node of the status of the interrogating
control point node as an alternate control point node, otherwise,
