description of the configuration parameters of the base SRM agent.The second part describes the architecture, internals, and the code pathof the base SRM agent.The last part of the chapter is a description of the extensionsfor other types of SRM agents that have been attempted to date.<P>The procedures and functions described in this chapter can be found intcl/mcast/srm.tcl,
