F5 BIG-IP Carrier-Grade NAT: Easy and secure migration to IPv6
Tired of having to deal with the management of your networks in the face of the exponential proliferation of wireless devices? Certainly, these interoperability challenges represent higher levels of depletion in the IPv4 address, which translates into a much slower transmission speed between networks.
However, with IPv6, the new generation of the Internet Protocol, these challenges can be better managed, since the hosts determine the MTU (Maximum Transmission Unit) before sending datagrams.
How to achieve a fast and secure migration to IPv6? Globenet International Corp in association with F5 Networks presents the BIG-IP Carrier-Grade NAT, a solution that will allow your network administrators to easily manage IPv4 address depletion by interoperating your existing IPv4 devices and at the same time migrate to IPv6 to take make a good use of the advantages.
The F5 BIG-IP Carrier-Grade NAT achieves these benefits because it has a broad set of tools, including tunneling solutions with Dual-Stack Lite capabilities as well as native network address translation solutions, such as NAT44 and NAT64.
Let’s see some of the advantages you can get with F5 BIG-IP Carrier-Grade NAT:
Scalability: This F5 solution offers a very high number of IP address translations, very fast NAT translation setup rates, high throughput and high-speed logging.
Performance improvements: This is achieved because BIG-IP CGNAT can scale to tens of millions of IP address translations, translation setup rates in the order of a million per second and tens of gigabits of performance. Performance improvements with high-speed logging allow you to reduce spending as you can handle your migration needs with fewer servers in the network.
Reduction of management costs: Thanks to a unified and easy-to-manage platform, server management costs can be simplified and lower investments can be achieved in CapEx, OpEx, energy and cooling.
How does F5 BIG-IP Carrier-Grade NAT manage the IPv4 address depletion?
The high capacity of Network Addresses translation in BIG-IP CGNAT enables you to deliver IPv4 connectivity and to handle high amounts of concurrent sessions as you manage IPv4 address depletion and plan for a seamless migration to IPv6.
NAT64: BIG-IP CGNAT provides NAT64 for those having IPv6-only endpoints deployed in their network. This will allow service providers with IPv6 endpoints to transparently access IPv4 content and destinations by translating between IPv6 and IPv4 addresses.
464XLAT: This support will be especially useful for handling everyday challenges such as having to manage, at the same time, networks and devices that migrate to IPv6 and applications and services that will continue to support only IPv4. The 464XLAT support allows service providers to implement a simple and scalable technique to gain access to IPv4 services for mobile and wireline IPv6 networks without encapsulation.
DNS64: This is another feature of this solution provided by F5 BIG-IP Global Traffic Manager. DNS64 allows IPv6 hosts to see IPv4 destinations as IPv6 addresses. For DNS servers that receive requests for a domain’s AAAA records (IPv6) but only find A records (IPv4), DNS64 synthesizes the AAAA records from the A records and forwards them to the user, enabling networks with IPv6-only endpoints to continue accessing IPv4 and IPv6 content. In addition, BIG-IP CGNAT interoperates with external DNS64 gateways, providing flexible deployment options in your network.
BIG-IP CGNAT also offers ALG support for point-to-point tunneling protocol (PPTP). This feature allows data to be sent across NAT without being broken up and without an F5 iRules or iApps template extension.
Tunneling: If you are one of the service providers that have implemented an IPv6 network, but you need to support legacy IPv4 endpoints, BIG-IP CGNAT guarantees tunneling technologies such as Dual-Stack Lite. This will allow IPv4 users to continue to access IPv4 content.
Dual-Stack Lite (DS-Lite): DS-Lite enables you to implement an IPv6-only access and aggregation network while still providing service to IPv4 endpoints and destinations. It is a tunneling solution in which endpoint IPv4 packets are encapsulated in an IPv6 tunnel and sent via the AFTR (Address Family Transition Router) to an external IPv4 destination through your network. Within the AFTR, the tunnel packet is decapsulated and a NAT44 function is applied to the tunneled private IPv4 traffic before delivering it to the public IPv4 destination. At the other end of the DS-Lite tunnel, the DS-Lite B4 (Basic Bridging Broadband) functionality occurs at the CPE device, such as the gateway.
So you know … if you already migrated to IPv6 or even if you need advice to boost the transmission speed and improve the interoperability of your networks, Globenet International offers you the possibility to take a step up through F5 BIG-IP Carrier-Grade NAT.
