Description of Working Group:
-----------------------------
The Border Gateway Protocol (BGP) is fundamental to the
operation of the Internet. In recent years, occurrences
of BGP related operational issues have increased, and
while overall understanding of the default-free routing
system has improved, there is still a long and growing
list of concerns. Among these are routing table growth
rates, interaction of interior and exterior routing
protocols, dynamic properties of the routing system, and
the effects of routing policy on both the size and
dynamic nature of the routing table. In addition, new and
innovative uses of BGP, such as the use of BGP as a
signaling protocol for some types of Virtual Private
Networks, have created new and unexpected operational
issues.
The purpose of the GROW is continue and expand on
the original charter of the PTOMAINE WG. In particular,
the purpose of the GROW is to consider and measure the
problem of routing table growth, the effects of the
interactions between interior and exterior routing
protocols, and the effect of address allocation policies
and practices on the global routing system. Finally,
where appropriate, the GROW documents the operational
aspects of measurement, policy, security, and VPN
infrastructures.
GROW will also advise various working groups, including
the IDR and RPSEC working groups, with respect whether it
is addressing the relevant operational needs, and where
appropriate, suggest course corrections. Finally,
operational requirements developed in the GROW can also
be used by any new working group charged with
standardizing a next generation inter-domain routing
protocol.
GOALS:
-----
(i). To provide a clear definition of the problems
facing Internet Routing Scaling today. This
includes routing table size and route processing
load (former PTOMAINE goal).
(ii). To collate measurements of routing table scaling
data and publish a reference list (former
PTOMAINE goal).
(iii). To discuss and document methods of
filtering/aggregating prefix information and to
discuss and document what support from protocols
or vendor knobs that might be helpful in doing
this. In addition, to suggest policy guidelines
to RIRs, LIRs and/or ISPs for allocations and
aggregations,etc. that may be useful (former
PTOMAINE goal).
(iv). To determine the long and short term effects of
filtering/aggregating prefixes to reduce router
resource consumption.
(v). To develop methods of controlling policy
information propagation in order to limit the
need for propagation of prefix sub-aggregates.
(vi). To determine the effects of using BGP as a
signaling mechanism on the scalability of BGP
(e.g.,. draft-ietf-ppvpn-rfc2547bis-03.txt)
(vii). To determine the effects of interaction of new
IGP techniques (e.g., ISIS-TE) on the stability
of BGP and in particular, what techniques are
required to isolate the global infrastructure
from the any of the dynamic properties of such TE
systems.
(viii). GROW will document operational aspects of routing
security and will provide recommendations for
protocol specific work to RPSEC, IDR, and other
WGs in Routing area.
