Use Cases
Deploying Native IPv6
Overview
gogo6 has developed new family of products that enables deployment of IPv6-only networks that can enable use of IPv6-only applications and provide interoperability with IPv4 networks. For enterprise based networks and certain other cases, this solution can provide same functionality as NAT-based IPv4 networks. The new family of products was developed as a result the latest developments in IPv4 address allocations trends and as a more direct response to the customers request for this type of products. The products offered by gogo6 allow operators to deploy IPv6-only networks and have IPv6 capable applications be able to interwork and communicate with legacy IPv4 applications
For certain network architectures, IPv6-only alternative can provide same functionality as IPv4 alternative, while lowering operational costs and enabling additional services. For instance, new enterprise networks having problems in obtaining new or additional IPv4 address space, can easily obtain IPv6 address space and deploy an IPv6-only network compatible with IPv4 networks. By deploying IPv6-only network instead of an IPv4-only network, the enterprise gains address independence from its access provider and can easily change its access provider or achieve multihoming with several providers. Furthermore, operators can easily deploy new IPv6-only services that are fully compatible with and accessible from the IPv4 Internet. See demoes.
Network Topology
IPv6-only networks are easily deployable and manageable compared to IPv4 NAT-based networks and dual-stack networks. Compatibility with IPv4 networks is provided through gogoSERVER Advanced product. End users are not aware of the network protocol used and can fully take advantage of both IPv4 and IPv6 versions. Moreover, access to IPv6 services from IPv4 hosts can be provided using gogo6 Overlay Connectivity technology.
Interworking between an IPv6 and an IPv4 network is achieved using a Network Address Translation-Protocol Translation (NAT-PT) mechanism. NAT-PT mechanism has similar functionality compared to Network Address Translation functionality, which is quite common and is extensively deployed in the Ipv4 world. The main difference between NAT-PT and NAT is that for IPv4, translation is entirely done between IPv4 address realms, whilst when used for translation between IPv4 and IPv6, translation is also done at the protocol level.
IPv6-only networks normally assumes that applications deployed are IPv6 capable. However, it is possible to support IPv4 applications in an IPv6-only network by using alternative transition mechanisms (for more information see Solution 1).
In IPv4, NAT function is normally located in host's default router. In IPv6, NAT-PT can be co-located with host's default router, but it does not have to be. Whilst in IPv4 traffic that needs to be translated is directed to the nearest NAT device using Ipv4 routing functionality, in IPv6 traffic that needs to be translated is directed to the nearest NAT-PT device using DNS functionality. For instance, when an IPv6-only capable host needs to communicate with an IPv4 host, it will start by performing a DNS lookup for host's domain name with a DNS that is aware of translation. The DNS server will execute DNS lookup on the behalf of the host and return an IPv6 address to the host pointing to the NAT-PT device. The NAT-PT device will in its turn accept IPv4 destined to the IPv4 host and make sure the communication between IPv6 and IPv4 host can take place.
This configuration implies that IPv6-only hosts that wish to communicate with IPv4 hosts need to use the DNS servers that are capable of NAT-PT devices. This is conceptually similar to setup where Ipv4 hosts located in private networks needs to be configured with default route pointing to a NAT capable gateway. However, since provisioning of both IPv4 and IPv6 hosts is done automatically using DHCP, providing hosts with default route or DNS server is already supported by most provisioning systems.
Product Information
Deployment of IPv6-only networks compatible with IPv4 networks is enabled by gogoSERVER product.
