Problems solved by technology

However, since these MAC sublayer protocols require fixed frames, these protocols limit the ways in which the network can be configured and operated
Furthermore, this fixed-frame architecture cannot be easily extended

Embodiment Construction

[0013] figure 1 is a block diagram illustrating an example of a network 100 comprising a plurality of nodes 120 connected by a communication link 140, which may be a wired link, a fixed wireless link, or a mobile wireless link. In network 100, messages may be segmented into data packets, such as data packet 130, and transmitted according to packet-switched protocols such as Transaction Control Protocol (TCP) / Internet Protocol (IP), X.25, and Frame Relay. Various embodiments of network 100 may be connected to another network, include one or more other sub-networks, and / or be a sub-network within another network. Several embodiments disclosed herein are applicable to wireless networks; such as networks utilizing the 802.15 or 802.16 standards as well as the WCDMA / CDMA 2000 3G standard.

[0014] In some embodiments, network 100 is a wireless smart grid network that monitors and controls various nodes 120, which are devices used to generate, distribute, monitor and / or manage elec...

Abstract

Methods are disclosed for generating a data packet at a sending node of the network that conforms to a media access control (MAC) layer protocol for network communications. The data packet includes a MAC header and a data segment, wherein data in said data segment is encoded as a type-length-value element identifying a value for an operating parameter of the network. The data packet is transmitted from the sending node to a receiving node. At the receiving node, the data packet is processed at the MAC sublayer of network protocols to retrieve said element and determine the value for the operating parameter. Operating parameters within the receiving node are adjusted to conform to the determined value of the operating parameter.

Description

technical field [0001] The present disclosure relates generally to the management and operation of devices connected by computer networks, and more particularly to the dynamic configuration of such devices. Background technique [0002] Network devices use protocol stacks that organize communication software in hierarchical layers. For example, the Open Systems Interconnection (OSI) model defines seven layers, including four upper layers for software applications, and three lower layers for processing data packets. The upper layer includes application layer, presentation layer, session layer and transport layer. The three lower layers include network layer, data link layer and physical layer. Network device management is usually implemented at the upper layers of the network and, to a limited extent, at the physical layer. [0003] The data link layer (ie, layer 2) is responsible for ensuring node-to-node validity and integrity of transmissions. The Data Link Layer (DLL)...
