Abstract:
A MultiProtocol Label Switching (MPLS) label was originally defined
to identify a Forwarding Equivalence Class (FEC). A packet is
assigned to a specific FEC based on its network layer destination
address, and optionally Class of Service. It's difficult or even
impossible to derive the source identity information from the label.
For some applications, source identification is a critical
requirement. For example, performance monitoring, where the
monitoring node needs to identify where a packet was sent from.
This document introduces the concept of Source Identifier (SI) that
identifies the ingress Label Switching Router (LSR) of a Label
Switched Path (LSP). A SI is unique within a domain that is referred
to as Source Identifier Administrative Domain (SIAD).
This document also introduces the concept of Source Label (SL) that
is carried in the label stack and carries the SI of the ingress LSR
of an LSP. Source Label is preceded by a Source Label Indicator
(SLI) when included the label stack and is not used for forwarding.
