Resumen:
The lack of investment in regional network infrastructures in Latin America (LA) has global consequences, particularly, in the area of interdomain Traffic Engineering (TE). For example, the region shows the world’s largest deaggregation factor of IP prefixes per Regional Internet Registry (RIR) region, so LA contributes considerably to the growth and dynamics of the global BGP routing table. In this paper, we first analyze the peculiarities of LA’s interdomain routing architecture, and provide up-to-date data about the combined effects of the current multihoming and TE practices in LA. We observe that, the IRTF initiative about the separation of the IP address space into locators and identifiers, not only offers appealing TE opportunities for LA, but can also contribute to considerably alleviate both the growth and dynamics of the global BGP routing table. We outline one of the solutions under discussion at the IRTF, namely, the Locator/Identifier Separation Protocol (LISP), and examine its potential in terms of interdomain traffic management in the context of LA. The key advantage of LISP is its non-disruptive nature. Unfortunately, the existing proposals for its control plane have some fundamental problems that hinder its possible deployment. In light of this, we introduce a new and 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.
