MPLS-TP – Multi-Protocol Label Switching Transport Profile (MPLS-TP) is a new technology developed jointly by the ITU-T and the IETF. The key motivation is to add OAM functionality to MPLS in order to monitor each packet and thus enable MPLS-TP to operate as a transport network protocol.
CSC Carrier Supporting Carrier is a hierarchical MPLS VPN architecture between the Service Providers.
OSPF and IS-IS for MPLS TE- You need OSPF or IS-IS to distribute link information such as reserved, unreserved and used bandwidth, metric, link colouring information.These informations are used by CSPT ( Constraint based shortest path first ) algorithm.
Actually all are the same thing. VPWS stands for virtual private wire service , VLL stands for virtual leased line and EoMPLS stands for Ethernet over MPLS.
Is MPLS mandatory for Traffic Engineering? What is Traffic Engineering in the first place ?
There are many posts about MPLS Traffic Engineering with RSVP on the Website, in this post we will look at the alternative approaches to the MPLS TE with RSVP.
Why do you need MPLS Traffic Engineering? – MPLS Traffic Engineering is a mechanism that provides cost savings in an MPLS networks.
Is Inter-AS MPLS VPNs commonly deployed ? In real-life deployment which Inter-AS MPLS VPN Option is most common ? What are the use cases of Inter-AS MPLS VPNs ? This is not a theory post , I will share practical information with you.
MPLS Traffic Engineering Fast Reroute Link Protection – I will explain it in plain English and the most important point of MPLS TE FRR Link Protection among other Fast Reroute mechanisms.
What is PLR, Point of Local Repair in MPLS Traffic Engineering ? PLR is the term is used in the context of Fast Reroute. I briefly mentioned from PLR in the MPLS Traffic Engineering Fast Reroute Link Protection post earlier and in this post, will explain it in more detail.
