VNET6: SOA Based on IPv6 Virtual Network

No more IPv4 address left with IANA or APNIC, IPv6 is critical to the Internet's continued growth. How can IPv6 be flexible and adaptive for a broad range of services? How can IPv6 network adapt to the services specified requirements with high quality of experiences to users? How can IPv6 network simplify management for services? How can IPv6 network provide reliable services? This paper is an attempt to answer these questions and proposes IPv6 Virtual Network Architecture (VNET6) to support flexible services in IPv6 network. Different from other network architecture proposed in the past, VNET6 supports incremental network evolution and VNET6 is an idealized service-oriented network architecture based on IPv6 and virtualization technologies. IPv6 is a critical protocol in VNET6 and Virtual networks are built above network layer of IPv6 protocol stack. Virtualization in VNET6 aims to be a scale-out architecture using multiple entities to build a logical entity. This paper presents the details of virtual consolidation, virtual partition and virtual service. VNET6 supports different services and has many advantages such as service flexibility, simple manageability and high reliability. Giving example considerations of optimizing video experience, VNET6 is adaptive to video service with high bandwidth and low tendency and improves quality of experiences to users.
