Y-Net Stack

The Y-Net protocol stack provides a set of advanced communication services enabling a standard, rapid and simple method of development for low cost command and control networking applications over the power line media using IT900A. The services provided by the Y-Net protocol stack enable developers to focus their efforts on the implementation of their applications, rather than on the communication and networking function.

The Y-Net stack provides high flexibility and an extensive range of modes and configurations for developing applications based on the most suitable network installation scenario requirements for that application. The Y-Net stack will support network installation scenarios varying from simple plug-and-play networks (Y-Net defaults) to highly secured networks.

The Y-Net protocol stack consists of the following:

➤ Physical (PHY) layer consisting of the physical interface to the power line media.

➤ Media access control (MAC) layer providing Y-Net stack interface for lower layer communication services.

➤ Network Layer (NL) providing Y-Net stack interface for advanced networking services such as ad-mission, routing and addressing.
