Abstract:
The Path Computation Element (PCE) is a functional component capable
of selecting paths through a traffic engineering (TE) network. These
paths may be supplied in response to requests for computation or may
be unsolicited requests issued by the PCE to network elements. Both
approaches use the PCE Communication Protocol (PCEP) to convey the
details of the computed path.
Traffic flows may be categorized and described using "Flow
Specifications". RFC 8955 defines the Flow Specification and
describes how Flow Specification components are used to describe
traffic flows. RFC 8955 also defines how Flow Specifications may be
distributed in BGP to allow specific traffic flows to be associated
with routes.
RFC 9168 specifies a set of extensions to PCEP to support
dissemination of Flow Specifications. This allows a PCE to indicate
what traffic should be placed on each path that it is aware of.
The extensions defined in this document extends the support for
Ethernet Layer 2 (L2) and Layer 2 Virtual Private Network (L2VPN)
traffic filtering rules either by themselves or in conjunction with
L3 flowspecs.
