AS number change could affect Internet routing from 1
January
2009
________________________________________________________________________
Manufacturers urged to upgrade routers and network
management
software to support the use of four-byte Autonomous
System numbers
by 1 January 2009.
Regional Internet Registries (RIRs), including Asia Pacific
Network
Information Centre (APNIC), have warned that routers and
network
management software should be upgraded ahead of the
increased
distribution of four-byte (also known as 32-bit) Autonomous
System (AS)
numbers.
AS numbers are a vital part of the Internet's core routing
system, the
Border Gateway Protocol (BGP). With existing two-byte AS
numbers
predicted to run out in early 2011, RIRs will issue
four-byte AS numbers
by default (unless otherwise specifically requested)
beginning 1 January
2009, as the next phase of a transition from two- to
four-byte
numbers.
Following a globally coordinated policy, RIRs began
allocating four-byte
AS numbers by request only in January 2007; January 2009
marks the
transition to allocating four-byte AS numbers by default.
Without timely support from vendors, network operators risk
having
routers and network administration systems that won't accept
the
expanded four-byte number format. As such, the RIRs urge
operators to
verify their vendors' routers will support four-byte AS
numbers.
Geoff Huston, Chief Scientist at APNIC, expressed severe
concerns over
failure to prepare for four-byte AS numbers: "AS numbers are
often used
to identify external relationships, set routing attributes,
and manage
traffic. Learning from our current experiences with IPv6
preparation
issues, Internet engineers designed four-byte AS numbers to
be backward
compatible with much of the installed network
infrastructure. But new
entrants and networks that are expanding or merging will
need new AS
numbers and as of 1 January 2009 these will be, by default,
four-byte AS
numbers. If router software and support systems in critical
parts of the
Internet's infrastructure aren't upgraded by January, we'll
encounter
some significant network routing problems. We're extremely
concerned
that a lot of routers and network management software out
there cannot
and will not be able to recognize four-byte AS numbers".
An Autonomous System (AS) is a collection of networks, or
routers,
administered as a group sharing a common set of routing
policies, each
defined with a unique number, or AS number. Massive Internet
growth has
depleted the existing pool of two-byte AS numbers (65,536
numbers in
total). As a result, engineers have expanded the AS number
space from
two bytes to
four-bytes, to include over 4 billion AS
numbers. Some
routers do not currently support the use of four-byte AS
numbers.
To help vendors understand what they need to do to provide
four-byte AS
number support and to help network operators find products
that support
four-byte AS numbers, APNIC has set up a special website at:
