As you've learned in this chapter, GMPLS extends MPLS to support non-packet/cell interfaces. The support of the additional TDM, lambda, and fiber interfaces impacts the basic LSP properties, such as how labels are requested and communicated and the unidirectional LSP behavior, error propagation, and so on.
Table 8-1 summarizes the basic differences between MPLS and GMPLS described in this chapter.
|Supports packet/cell-based interfaces only.||Supports packet/cell, TDM, lambda, and fiber.|
|LSPs start and end on packet/cell LSRs.||LSPs start and end on “similar type” LSRs (that is, PSC, L2SC, TDM, LSC, FSC).|
|Bandwidth allocation can be done in any number ...|
