label switched path การใช้

• PCE applications compute label switched paths for MPLS and GMPLS traffic engineering.
• For example, IP links can be realized by protected MPLS using Label Switched Paths  LSPs ( IP over MPLS ).
• "' HSMP LSP "'is hub & spoke multipoint Label Switched Path ( P2MP LSP to each leaf node.
• RSVP-TE generally allows the establishment of MPLS label switched paths ( LSPs ), taking into consideration network constraint parameters such as available bandwidth and explicit hops.
• In the Resource Reservation Protocol ( RSVP ), OSPF-TE is used for recording and flooding RSVP signaled bandwidth reservations for label switched paths within the link-state database.
• In Fig . 1 ( right ), there is a primary path ( Label Switched Path, or LSP ) from A to E via B and D . The traffic of customers connected to A and E will take this path in normal operation.
