Method of changing program of network node remote from network management system
First Claim
1. A program-changing method for a network comprising at least two nodes that each have a program, said network further comprising a network management system (NMS) coupled to a first node of the nodes, the method comprising the steps of:
- (a) transmitting, by the network management system (NMS), a new program data and a first control signal to said first node coupled to the network management system (NMS) disposed in the network separately from the nodes and configured to manage the changing of the programs of the nodes;
(b) allocating a fixed region in a memory within said first node in response to the reception of the new program data, storing the received new program data in the allocated fixed region, and replacing the program of said first node coupled to the network management system (NMS) with the new program data responsive to the first control signal;
(c) causing the network management system (NMS) to transmit to said first node a data-transmitting signal for transmitting the stored new program data to a second node, and transmitting, by the network management system (NMS), a second control signal to said second node for program-changing; and
(d) in response to the data-transmitting signal, causing said first node to transmit the stored new program data thereof to said second node for program-changing.

Abstract
A program-changing method for a network having at least two nodes that include a first and a second predetermined node, each network node having a program, includes a network management system connected to the first predetermined node of the network. New changing program data and a control signal are transmitted to the first predetermined node connected to the network management system which is disposed in the network separately from the nodes and configured to manage the changing of the programs in the nodes. The first predetermined node replaces its program with the new changing program data. The network management system transmits a program-transmitting-signal to the first predetermined node, causing the transmission of the newly changed program data stored therein to the next predetermined node to change the program of the next predetermined node under control of a respective control signal to the second predetermined node from the network management system.

4. A program-changing method for a network comprising a plurality of nodes including a first node and a second node, each of the first and second nodes having a program, the method comprising the steps of:
-
(a) transmitting a new program data and a first control signal to the first node, said first node being coupled to a network management system (NMS) located in the network remotely from the plural nodes; (b) changing the program of said first node to said new program data under the control of said control signal; (c) storing said new program data in a memory means of said first node; (d) transmitting, by said NMS and to said first node, a first command signal to transmit the stored new program data to the second node and transmitting a second control signal to said second node; and
,(e) upon receiving said stored new program data from said first node, changing the program of said second node to said new program data under the control of said second control signal. - View Dependent Claims (5, 6, 7, 13)

8. A program-changing method for a plurality of nodes that each have a program, said nodes being arranged in a network having a network management system (NMS) remote from the plural nodes and coupled to one of the plural nodes, the method comprising the steps of:
-
(a) transmitting a new program data and a first control signal to the one of the plural nodes coupled to said network management system (NMS) which is disposed in the network separately from the plural nodes; (b) storing said new program data in a memory means of the one node; (c) changing the program of said one node to said new program data under the control of said first control signal; (d) transmitting, by said NMS to said one node, a first command signal to transmit the stored new program data to another of the plural nodes and transmitting a second control signal to the another node; and (e) upon receiving said stored new program data, changing the program of said another node to said new program data under the control of said second control signal. - View Dependent Claims (9, 10, 11)

17. A program-changing method for a network that includes a plurality of nodes and, connected to a node of the plural nodes, a Network Management System (NMS), the plural nodes being connected in a particular formation, said method comprising the steps of:
-
transmitting a new program, from the NMS, to a first node of the plural nodes; and iteratively propagating the new program forward along said formation from said first node to a second node, from the standpoint of inter-node hops on said formation, is an immediately neighboring node of corresponding said first node such that the second node and receives the new program, and receives said new program exactly once, each of said inter-node hops of the propagation being controlled by the NMS, wherein the NMS exercises the control by issuing two types of signals, one of the types being a program-changing signal that commands a first node of the plurality of nodes to, by storing at a fixed, allocated portion of memory at said first node, replace, with the new program, a program stored in said memory of said first node, the other type being a data-transmitting signal that commands said first node to retrieve the new program from said memory and to transmit the retrieved program to a second node immediately neighboring the first node. - View Dependent Claims (18, 19, 20, 21)
