Abstract:
This document describes a new OAM protocol - TraceFlow that captures
information pertaining to a traffic flow along the path that the flow
takes through the network. TraceFlow is ECMP and link-aggregation
aware and captures the information about constituent members through
which the traffic flow passes. TraceFlow gathers information that is
relevant to the flow such as outgoing interface Layer 3 address,
Next-hop to which the packet of the flow is forwarded, effect of
network policies such as access control lists on the flow. This draft
requires the Traceflow protocol to be processed by Layer 3 devices
only. Devices such as Layer 2 devices, MPLS LERs/LSRs along the way
are passed through without any processing as if in a pass-through
mode. IP tunnels such as IP-in-IP, IP-in-GRE mechanisms are expected
to pass the Traceflow packets through them using the pass through
mode. For achieving its purpose Traceflow advocates the use of a
specific UDP destination port to be assigned from IANA.
