An Incremental Approach to IPV6 Multihoming
MetadatosMostrar el registro completo del ítem
The availability of two or more connectivity providers (conﬁguration known as multihoming) allows improvements in failure tolerance and enables trafﬁc engineering capabilities. Current IPv4 multihoming solutions suffer from scalability limitations. In this article we present a solution that allow IPv6 networks to beneﬁt from multihoming, taking advantage from the fact that each provider delegates its own set of addresses. The proposed solution consists in multiple mechanisms that provide different beneﬁts to the multihomed site. More precisely, the solution includes a mechanism for the provision of ingress ﬁltering compatibility, a mechanism for establishing new communications after an outage, a set of tools for trafﬁc engineering and a protocol for preserving established communications through outages. In addition we propose a roadmap for the incremental deployment of the set of mechanisms included in the solution based on the trade-off between deployment effort required by each mechanism and the beneﬁts obtained by the involved party.
