A. CONSTRUCTING AN IP NETWORK ADDRESSING PLAN
This annex summarizes the rules for constructing a TMN based on the IP protocols suite.
A.1 - Preamble
The IP protocols suite enables the transport of data in a transmission network in the form of
packets between two points in the network.
According to the ISO model, IP is the network layer protocol. It is therefore responsible for the
packet routing of each node, so that the packets can be routed correctly via the network.
The protocols "below" IP correspond to the link and physical layers: they set up the links
between two consecutive network nodes.
The protocols "above" IP, TCP and UDP, are the transport layer protocols: they enable end-to-
end data transmission between two remote points on the network. The protocols based on
TCP/UDP are application oriented: they offer services such as file transfer (TFTP over UDP,
FTP over TCP), equipment management (SNMP), messaging (SMTP), etc...
The figure below describes the stacking of the main protocols that can be used in a network
node.
Note: The MAC protocol is linked to the Ethernet physical port (point-multipoint media) and
PPP protocol is linked to the physical ports for the point-to-point links (optical, radio,
V11 , etc...)
