A QoS-Driven ISP Selection Mechanism for IPv6 Multi-homed Sites
نویسندگان
چکیده
A global solution for the provision of QoS in IPng sites must include ISP selection based on per-application requirements. In this article we present a new site-local architecture for QoS-driven ISP selection in multi-homed domains, performed in a per application basis. This architecture proposes the novel use of existent network services, a new type of routing header, and the modification of address selection mechanisms to take into account QoS requirements. This proposal is an evolution of current technology, and therefore precludes the addition of new protocols, enabling fast deployment. The site-local scope of the proposed solution results in ISP transparency and thus in ISP independency.

متن کاملLeveraging Network Performances with IPv6 Multihoming and Multiple Provider-Dependent Aggregatable Prefixes
Multihoming, the practice of connecting to multiple providers, is becoming highly popular. Due to the growth of the BGP routing tables in the Internet, the way to multihome in IPv6 is required to preserve the scalability of the interdomain routing system. A proposed method is to assign multiple provider-dependent aggregatable (PA) IPv6 prefixes to each site, instead of a single provider-indepen...

The successful and increasingly adopted Session initiation Protocol (SIP) does not adequately support hosts with multiple network addresses, such as dual-stack (IPv4-IPv6) or IPv6 multi-homed devices. This paper presents the Address List EXtension (ALEX) to SIP that adds effective support to systems with multiple addresses, such as dual-stack hosts or multi-homed IPv6 hosts. ALEX enables IPv6 t...
متن کاملA MIPv 6 - based multi - homing solution
Global adoption of IPv6 requires the provision of a scalable support for multi-homed sites. This article proposes a multi-homing solution based on the usage of the currently available MIPv6 protocol. It is shown that the MIPv6 protocol is suitable to be used for the provision of IPv6 multi-homing support without modifications in the packet formats defined in the specification, and that it only ...
