Figure:6 Functional model
Description
This section presents the feature and list the requirements needed to make it understandable to the end-
user.
The purpose of the Dispatcher is to act as communication bridge between a serial device and multiple TCP/
IP devices.
Description of Data Flow
FR001 The Dispatcher expect the data coming from the serial port to respect the format defined
in Figure 4 - Dispatcher Protocol
FR002 In normal circumstances (see Figure 4 - Dispatcher Flow char), the Dispatcher extracts the
Message section of the Data packet (shown in Figure 4 - Dispatcher Protocol) received on
the serial port, it then decode it to a TCP/IP segment and finally sends it to the IP address/
TCP port number that matches the Link ID.
FR003 In normal circumstances (see Figure 3 - Dispatcher Flow char), the Dispatcher extracts the
data contain in a TCP/IP segment it receives from an opened TCP/IP connection; it then
encapsulate it to a Serial data packet (see Figure 4 - Dispatcher Protocol) and finally
forwards it onto the Serial connection.
