HIDRA: Hierarchical Inter-Domain Routing Architecture

As the Internet continues to expand, the global default-free zone (DFZ) forwarding table has begun to grow faster than hardware can economically keep pace with. Various policies are in place to mitigate this growth rate, but current projections indicate policy alone is inadequate. As such, a number of technical solutions have been proposed. This work builds on many of these proposed solutions, and furthers the debate surrounding the resolution to this problem. It discusses several design decisions necessary to any proposed solution, and based on these tradeoffs it proposes a Hierarchical Inter-Domain Routing Architecture - HIDRA, a comprehensive architecture with a plausible deployment scenario. The architecture uses a locator/identifier split encapsulation scheme to attenuate both the immediate size of the DFZ forwarding table, and the projected growth rate. This solution is based off the usage of an already existing number allocation policy - Autonomous System Numbers (ASNs). HIDRA has been deployed to a sandbox network in a proof-of-concept test, yielding promising results

Domain Identifiers In A Next Generation Internet Architecture

In this paper we make the domain entity a first class citizen. The concept of Domain Identifiers (DIDs) is introduced to effectively bring the domains to the next generation Internet scenario. The paper presents an architecture to address challenging next generation Internet requirements such as node and domain mobility, multi-homing, security, network composition and inter-domain routing. Although our architecture supports all the mentioned requirements, the focus of this paper is specifically on node and domain mobility in order to evaluate and compare the advantages of having DIDs for facilitating the mobility. First, we present the generic Next Generation Internet architecture proposal and its envisioned scenario. Then, we show how to instantiate it to work together with the current Internet. We have developed a prototype to evaluate our proposal and we depict results related to node and domain mobility under this gradual deployment scenario using the Internet as the core. © 2009 IEEE.Farinacci, D., Fuller, V., Oran, D., Meyer, D., Locator/ID Separation Protocol (LISP) (2007) IETF Draft - draft-farinacci-lisp-05. txt, p. 14. , NovSchuetz, E.S., Winter, R., Burness, L., Eardley, P., Ahlgren, B., Node Identity Internetworking Architecture (2007) IETF Draft - draft-schuetz-nidarch- 00, , September, 14Moskowitz, R., Nikander, P., (2006) Host Identity Protocol (HIP) Architecture, , IETF RFC-4423, MayM.
