Hi,
This is the latest version of the BGP-PIC draft that was presented on
Nov/2/15 during the IETF-94 meeting in Yokohama
We have addressed the comments as follows:
- Added statements in multiple places, including the abstract,
indicating the need for more than one BGP path
- Added example in Section 2.3.3 with illustrations in Figure 4,5,6 on
how to handle a platform that does not support the required number of
hierarchy levels. Section 4.3 explains the gradual degradation of
BGP-PIC benefit as a result of the reduced platform support
- For handling unlabeled traffic in case PE-CE failure, the last bullet
in Section 4.2.2 indicates that an egress PE must always treat a core
facing path as a backup path to avoid looping the packet in case of
PE-CE link failure. The first statement in Section 5.1 indicates that
the draft does not cover the failure of a CE node
We would like to request adoption of the draft.
Thanks
Ahmed

Abstract:
In the network comprising thousands of iBGP peers exchanging millions
of routes, many routes are reachable via more than one path. Given
the large scaling targets, it is desirable to restore traffic after
failure in a time period that does not depend on the number of BGP
prefixes. In this document we proposed an architecture by which
traffic can be re-routed to ECMP or pre-calculated backup paths in a
timeframe that does not depend on the number of BGP prefixes. The
objective is achieved through organizing the forwarding chains in a
hierarchical manner and sharing forwarding elements among the maximum
possible number of routes. The proposed technique achieves prefix
independent convergence while ensuring incremental deployment,
complete transparency and automation, and zero management and
provisioning effort. It is noteworthy to mention that the benefits of
BGP-PIC are hinged on the existence of more than one path whether as
ECMP or primary-backup.
Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
