“…In August 2003, RFC3582 [1] "Goals for IPv6 Site-Multihoming Architectures" explained the need for multi-homing and set out some clear goals, including scalability ("A new IPv6 multihoming architecture should scale to accommodate orders of magnitude more multihomed sites without imposing un-reasonable requirements on the routing system.") and limited cooperation ("A multihoming strategy may require cooperation between a site and its transit providers, but should not require cooperation (relating specifically to the multihomed site) directly between the transit providers").…”

Companies seeking to ensure that their Internet connection is resilient often purchase services from multiple providers. This leads them inexorably towards having their IP address range visible in the global routing table, increasing the resource usage of every Internet router. Since this is essentially 'free', yet impacts the cost and stability of every router in the world, this is a classic 'tragedy of the commons'. There is little prospect of change in the IPv4 world, but there is a chance to fix the problem as IPv6 is rolled out. Unfortunately, SHIM6, the engineering solution chosen to solve this issue in IPv6, will only be effective if universally adopted, and there are no short-term incentives to prefer SHIM6 over a duplication of the IPv4 arrangements. Incentives could be artificially introduced by requiring payment for adding multihomed address space to the global routing table -a naïve estimate of the actual cost being 77 000 per routing prefix. However, it would be almost impossible to ensure the substantial revenues involved are correctly redistributed to those bearing the costs.

“…Multihoming in IPv6 has been viewed as a problem of the end host, suffering under the fact that the IPv6 standards allow multiple IPv6 addresses to be assigned to end terminals. There are two RFCs studying the general goals of multihoming at site level: [67] presents the goals and [68] proposes a partial solution to allow multihoming support at the site exit. Ambiguities at end system or site level have been ignored up to the moment.…”

Research challenges in QoS routing

Quality of Service Routing is at present an active and remarkable research area, since most emerging network services require specialized Quality of Service (QoS) functionalities that cannot be provided by the current QoS-unaware routing protocols. The provisioning of QoS based network services is in general terms an extremely complex problem, and a significant part of this complexity lies in the routing layer. Indeed, the problem of QoS Routing with multiple additive constraints is known to be NP-hard. Thus, a successful and wide deployment of the most novel network services demands that we thoroughly understand the essence of QoS Routing dynamics, and also that the proposed solutions to this complex problem should be indeed feasible and affordable. This article surveys the most important open issues in terms of QoS Routing, and also briefly presents some of the most compelling proposals and ongoing research efforts done both inside and outside the E-Next Community to address some of those issues. q

“…As a criteria for the analysis of the security offered by the new multihoming solutions, it is usually required that they should not enable vulnerabilities that are not possible in the current IPv4 infrastructure [14]. With the tools that have been presented so far, we can think of new attacks that are not possible when the identifier and locator functions are integrated in a single IPv4 address, as it is the current case.…”

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. q
