Abstract:
An MultiProtocol Label Switching (MPLS) label is originally defined
to identify a Forwarding Equivalence Class (FEC), a packet is
assigned to a specific FEC based on its network layer destination
address. It's difficult or even impossible to derive the source
information from the label. For some applications, source
identification is a critical requirement. For example, performance
monitoring, traffic matrix measurement and collection, where the
monitoring node needs to identify where a packet was sent from.
This document introduces the concept of Source Label (SL) that is
carried in the label stack and used to identify the ingress Label
Switching Router (LSR) of an Label Switched Path (LSP).
