6.10.1.1 Interface Statistics Conventions
To reduce their design complexity, most networks are organized as a series of layers or levels, each one
built upon its predecessor. Layer n on one machine carries on a conversation with layer n on another ma-
chine. The rules and conventions used in this conversation are collectively known as the layer n protocol.
The number of layers, the name of each layer, the contents of each layer, and the function of each layer
differ from network to network.
Figure 60 below illustrates layers and protocols applicable to Dataradio network architecture implementa-
tion. The five basic layers are:
Physical Layer
Datalink Layer
Network Layer
Transport Layer
Application Layer
Figure 60 - Layers and protocols applicable to Dataradio implementation
In reality, no data are directly transferred from layer n on one machine to layer n on another machine. In-
stead, each layer passes data and control information to the layer immediately below it, until the lowest
layer is reached (Figure 61).
Paragon4 radio base station web interface presents data transmission statistics for the Datalink layer.
Network and Transport layers statistics are not accessible through the web interface; they are provided in
1213 MIB and can be accessed through a MIB browser or an SNMP manager (see section 6.8.4.3: SNMP
Overview for more details on 1213 MIB).
