GMPLS constraints consideration for CSPF path computation
This draft provides the guideline to consider generalized multi- protocol label switching (GMPLS) traffic-engineering (TE) attributes for constraint-based shortest path first (CSPF) path computation at a source node in a GMPLS network environment. This draft summarizes most possible cases of GMPLS constraint TE attributes at an ingress link, transit links and an egress link to establish a GMPLS label switched path (LSP) appropriately.
