9.6 Creating a New Agent

To create a new agent, one has to do the following:

1.

sep0pt

2.

decide its inheritance structureSectionsec:pingexample, and create the appropriate class definitions,

3.

define the []recv and []timeout methods Sectionsec:agents:exmethods,

4.

define any necessary timer classes,

5.

define OTcl linkage functionsSectionsec:agents:exlinkage,

6.

write the necessary OTcl code to access the agentSectionsec:agents:exotclcode.

The action required to create and agent can be illustrated by means of a very simple example. Suppose we wish to construct an agent which performs the ICMP ECHO REQUEST/REPLY (or ``ping'') operations.
