Abstract

Aspects of the subject disclosure may include, for example, a first network device receiving from a second network device a software, the first network device adjusting operations at the first network device according to the software, the first network device providing a digital signature to the software to generate an adjusted software where the digital signature indicates that the first network device has received the software, and the first network device transmitting, to a third network device, the adjusted software. Other embodiments are disclosed.

First claim

What is claimed is:

1. A first waveguide system comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of first operations, the first operations comprising:
transmitting, to a second waveguide system, first electromagnetic waves via a transmission medium;
wherein the first electromagnetic waves are guided by the transmission medium without requiring an electrical return path;
wherein the first electromagnetic waves convey data including a software program;
wherein the software program is received by the second waveguide system from the first waveguide system without being received directly from a network source server that originated the software program;
wherein a hierarchical configuration of the first waveguide system and the second waveguide system is dynamically organized such that the first waveguide system is designated as a root node, for distribution of the software program, for a group of elements comprising the second waveguide system; and
wherein the transmitting of the first electromagnetic waves facilitates adjusting second operations at the second waveguide system utilizing the software program.

2. The first waveguide system of claim 1 , wherein the first operations facilitate:
transmitting by the second waveguide system, to a third waveguide system, second electromagnetic waves via the transmission medium, wherein the second electromagnetic waves are guided by the transmission medium without requiring the electrical return path, and wherein the second electromagnetic waves convey the data; and
providing, by the second waveguide system, a digital signature to the data being transmitted to the third waveguide system, wherein the digital signature indicates that the second waveguide system has received the software program.

3. The first waveguide system of claim 2 , wherein the software program comprises a software program update associated with an existing software program at the second waveguide system, wherein the data received from the first waveguide system includes another digital signature indicating that the first waveguide system received the software program update.

4. The first waveguide system of claim 2 , wherein the second waveguide system is an adjacent node to the first waveguide system and to the third waveguide system, and wherein the adjusting of the second operations at the second waveguide system comprises adjusting an operating system of the second waveguide system according to the software program.

5. The first waveguide system of claim 2 , wherein the group of elements further comprises the third waveguide system.

6. The first waveguide system of claim 1 , wherein the second operations comprise:
determining an applicability of the software program to the second operations of the second waveguide system, wherein the adjusting of the second operations at the second waveguide system is responsive to a determination that the software program is applicable to the second operations of the second waveguide system.

7. The first waveguide system of claim 1 , wherein the transmitting of the first electromagnetic waves is responsive to receipt, by the first waveguide system, of an update request from the second waveguide system.

8. The first waveguide system of claim 7 , wherein the update request is transmitted by the second waveguide system, to the first waveguide system, using second electromagnetic waves, wherein the second electromagnetic waves are guided by the transmission medium without requiring the electrical return path, and wherein the second electromagnetic waves convey the update request.

9. The first waveguide system of claim 1 , wherein the first waveguide system and the second waveguide system are adjacent nodes in a wired network comprising power lines that are the transmission medium, and wherein the first waveguide system receives the data from the network source server that originated the software program.

10. A method comprising:
dynamically organizing a hierarchical configuration of a first waveguide system and a second waveguide system such that the first waveguide system is designated as a root node, for distribution of a first software program, for a group of elements comprising the second waveguide system;
authenticating, by the first waveguide system, the second waveguide system according to authentication information received from the second waveguide system;
responsive to an authentication of the second waveguide system by the first waveguide system, transmitting the first software program by the first waveguide system to the second waveguide system;
adjusting operations at the second waveguide system according to the first software program;
providing, by the second waveguide system, a digital signature to the first software program to generate an adjusted software program, wherein the digital signature indicates that the second waveguide system has received the first software program; and
transmitting by the second waveguide system, to a third waveguide system, the adjusted software program.

11. The method of claim 10 , wherein the first, second and third waveguide systems each transmit and receive electromagnetic waves at a respective physical interface of a transmission medium, wherein the electromagnetic waves are guided by the transmission medium without requiring an electrical return path, and wherein the authentication information, the first software program and the adjusted software program are conveyed via the electromagnetic waves.

12. The method of claim 10 , wherein the second waveguide system is an adjacent node to the first and third waveguide systems, and wherein the method further comprises:
responsive to another authentication of a fourth waveguide system, receiving, by the second waveguide system from the fourth waveguide system, a second software program; and
comparing the second software program with the first software program;
wherein the adjusting of the operations at the second waveguide system according to the first software program is responsive to a determination that the first software program is a later version than the second software program.

13. The method of claim 10 , further comprising:
transmitting, by the second waveguide system, an update request to other elements of the group of elements including a fourth waveguide system, wherein the transmitting of the update request does not include providing the update request to a network source server that originated the first software program; and
determining, by the second waveguide system, a latest version of the first software program being stored by each element of the group of elements,
wherein the transmitting the first software program by the first waveguide system to the second waveguide system is responsive to a determination that the first waveguide system has the latest version of the first software program.

14. The method of claim 10 , wherein the first software program comprises a software program update associated with an existing software program at the second waveguide system, wherein the method further comprises determining an applicability of the software program update to the operations of the second waveguide system, wherein the adjusting of the operations at the second waveguide system is responsive to a determination that the software program update is applicable to the operations of the second waveguide system, and wherein the adjusting of the operations at the second waveguide system comprises adjusting an operating system of the second waveguide system according to the first soft
