Re: [ns] MPLS simulation

Chrysostomos,


        The MPLS implementations you found are the same. They were
implementated by the same person and there are very few diferences between
them, basicly bug fixes.

        The major diference is that in version 2.1b7 the tcl class structure
was changed a little bit to reflect some changes on the ns node tcl class
structure. You don't have a MPLSNode tcl class anymore.

        Instead, the ns-mpls-node.tcl file installs new MPLS methods, the
same ones you find at earlier versions, into the regular ns node and then,
at simulation time, you get a reference to the MPLS module. The C++ classes
weren't modified.

        The only problem with this setup is that I don't know how to create
new MPLS tcl classes based on this new structure.

        But, as far as I know, this MPLS implementation works fine.
