- Some Explaination of MPLS Code
- August 29, 2000
- - MPLS CODE IS HIGHLY EXPERIMENTAL AND IS NOT THOROUGHLY TESTED. YOU
- SHOULD CAREFULLY VALIDATE IT FOR YOUR SPECIFIC USAGE. IF YOU FIND
- ANY BUG, OR HAVE ANY PATCH, PLEASE SEND TO ns-users@isi.edu
- - It does not work with multicast routing, particularly because (1)
- there is no label setup mechanism for multicast groups, (2) there is
- no multicast replicator to cooperate with MPLS classifier, and (3)
- MPLS header contain pointers, which do not work with multicast
- replicator.
- - It works only with flat unicast routing but not hierarchical routing
- in any form. This is because current node-config architecture only
- provides exclusive node types, namely, a node cannot supports
- hierarchical routing and MPLS at the same time.
-
- - Some interfaces in MPLS classifier and MPLS node are expected to
- change in the near future to accomodate a new design of node-config
- mechanism.
- - There are no simple example files of MPLS code, because the ones in
- MPLS test suite are enough to serve as examples. Please read
- tcl/test/test-suite-mpls.tcl.
