126 Chapter 4
The primary focus of this book is on the Transport layer/Network layer that enables
the delivery of Carrier Ethernet??”specifically the MEF Carrier-class E-Line and E-LAN
services, as defined in Chapter 2. The network technologies and solutions (these terms
are used interchangeably throughout the book) that make up this layer are manifested
in physical equipment??”the hardware and software??”generally offered commercially by
several vendors. The physical equipment is usually made up of several discrete Network
Elements (NEs) that are configured collectively to provide Carrier Ethernet services.
