The characteristics of Latin American network
infrastructures have global consequences,
particularly in the area of interdomain traffic
engineering. As an example, Latin America
shows the largest de-aggregation factor of IP
prefixes among all regional Internet registries,
being proportionally the largest contributor to
the growth and dynamics of the global BGP
routing table. In this article we analyze the
peculiarities of LA interdomain routing architecture,
and provide up-to-date data about the
combined effects of the multihoming and TE
practices in the region. We observe that the
Internet Research Task Force initiative on the
separation of the address space into locators
and identifiers can not only alleviate the growth
and dynamics of the global routing table, but
can also offer appealing TE opportunities for
LA. We outline one of the solutions under discussion
at the IRTF, the Locator/Identifier
Separation Protocol, and examine its potential
in terms of interdomain traffic management in
the context of LA. The key advantage of LISP
is its nondisruptive nature, but the existing proposals
for its control plane have some problems
that may hinder its possible deployment. In
light of this, we introduce a promising control
plane for LISP that can solve these issues, and
at the same time has the potential to bridge the
gap between intradomain and interdomain traffic
management.Peer ReviewedPostprint (published version
