TCP/IP Network Requirements

This section provides a general description of ethernet networks, TCP/IP and
X.25 protocols and the requirements needed to support the operation of INM
Broadband.

Ethernet

The ethernet protocol is a standard defined by the Institute of Electrical and
Electronics Engineers (IEEE) for communication networks. The IEEE
standard 802.3 defines the layer 2 functionality in the protocol stack shown
